If you change one wrong byte, can either blow your motor, or fry you ECU. So we have to consider that.

Oooo... that's a big one. Take your time to get it right.

If the goal is to use a GUI so that we can (in order): 1) mod, 2) baseline flash to the ECU and perform an initial tune, 3)datalog, 4)rewrite & reflash 5)and retune. And be fully reversible, too.

To do that process over and over again based on further performance modifications to a car, then you guys really have something there. That's the type of user interface we would all like to see.

I'm not interested in sending my ECU some place to get flashed. One of 'our' beloved vendors has such a policy with their piggyback unit, and I'm just not a fan of that particular process. Good luck.

Thats awesome cant wait to get my hands on this!!! please start with the fed spec!!!!!

Oh, you're definitely there. No one yet has done it, and there is a definite need for it. This is a good start but you'll still need to "get the word out" after you've got the work nailed down.

If someone is willing to give me a FED spec ECU... then I can work on it. Till then, it's nothing I can do, I don't own a 3rd gen.

It's a pros to cons to your statement. Yes it would be easy to just reprogram your ECU over and over again for every mod you do. The cons are you have so many times you can reflash your ECU internal Flash Memory. If you re-flash too many times, your ECU will refuse to erase, or have a dead ECU causing you to buy a new ECU. The expected life of the erase and re-write are 100 times. Some I have seen over 100 times, and others only 30 times.

So this is something that should not be played with, and taken seriously. And by reading your post, I see that you understand that. So we have alot to think about releasing a user-tuner, as we don't want to be responsible of people blowing there cars up, or making there ECU inoperable.

So it will be a while for any release of user-tune.

I appreciate your candor. Sometimes getting your fuel trims in closed loop right takes several tuning attempts. It is good to know that there is a finite number of times you can flash. Not to mention that this ECU is not cheap if it is fried.

Fuel Trims in closed has nothing to do with adjusting fuel maps unless you change 80hex which is 14.7:1 in the low RPM and load ranges. Mitsubishi uses a 4 different sets of trims, 2 long terms and 2 short terms trim controls. The 2 fuel maps, the ECU uses that for OPEN LOOP fueling. Timing works with open loop and closed loop.

repforenzo · 02/14/2006, 10:29 PM

That's not true... if your fuel maps are designed for a specific application and you change it (with CAI, headers, etc) your fuel trims will be off in closed loop. I found that out when I installed some long tube headers and eliminated the EGR. My fuel trims went from right on, to leaning out on what was once a good map. Since I've changed variables, the map is too rich for stoitch (14.7:1)

Here my current averages for a 2700 rpm closed loop cruise, both short and long term (Bank 1: Short Term=-3.1 Long Term=-7.0 Bank 2: Short Term=-2.4 Long Term=-6.3). Now, that isn't bad, but the original map is now rich to maintain 14.7:1 without have to pull back the fuel trims.

Maybe I'm coming too much from the piggyback unit side of the argument... But along with observing you EGT, AFRs, Timing, etc. in a WOT situation, it is almost more important to have the closed loop operation as close to stock as possible... At least that is what I've been told countless times.

Not trying to get in any pissing match here at all. You definitely seem to be an authority on these ECUs and I definitely want to see your product realized. The basis for my arguement is that my friend used the Split Second program to change his fuel maps in his ECU to get zeroed fuel trims... he's got a supercharged Toyota T-100. Thanks.

My personal experience seems to say otherwise. However, I am no ECU expert my no means. It seems there is some sort of correction factor for WOT that carries over from closed loop fuel trims. I would think it would be to adjust for chages in fuel system as things age. Here is my experience with fuel trims and WOT A/F ratios.

Odd lean situation

Humm I want this. If they are getting 10WHP it might be worth it. Any idea on price.

Also since I have my SAFC 1 tuned for my N20 will this interfer with that?

hi, jaytech,

have e-mailed your company, directed to justin as he is listed as the tech but no replies. have sent a couple of mail over a week period! FYI.

anyway as i wrote previous, i live in Peoria & would be willing to meet with you or whom ever regards using my 00' GT as a test subject, if interested?
already have your location map quested & am willing to spend the day or even leave the car if needed. ( as long as i have some way to get back & forth).

car is NA with only a compete intake system PnP'd. headers, flow through exhaust, CAI.

PLMK if i can be of some assistance regards this issue...623-399-6497 or lwbobbe@cox.net...............larry

Tearstone · 02/15/2006, 07:09 PM

Stilwrks, if I were you call them up directly with the number on the website.

The rest of you guys... please relax. I know you all are excited about this but we are really onto something revolutionary and they are willing to help.

I spoke to Jay tonight and he will no longer be posting on this website. So if anyone has any questions about their products please route them through me. I will be providing you all with periodic updates as they come through.

Thank you, Russ, for stepping in and being the voice of reason here.

People, just step back and give these guys a chance to do their work. We've waited a long time for something like this and when the word comes out, as you would expect, a lot of people (myself included) get excited. Hell I spent 15 minutes trying to explain what this really means to my wife (and she understands cars) and she really thought I'd lost it. Well now everyone wants to know "how are you going to handle this?" and "what about that?" People, many of them entirely well-meaning, are giving advice and asking questions when these guys are just at the beginning of their work. It's a bit like trying to cook Thanksgiving dinner with your mom, your wife's mom, your wife, and your grandmother all trying to help (yeah, I did all the cooking). Sometimes it's easier to work things out on your own without everyone's questions and input, because everyone has their own ideas and things they want to see done, but it's not all headed in the same direction. We've got N/A guys, turbo guys, nitrous guys, RIPP guys, everyone vying for their attention. It sounds like they definitely know what they're doing, so let's just try to chill and be patient. It would be a HUGE shame if we badger these guys so much that they decide to drop the project, seriously. I think we could ALL afford to wait 6 months, hell a year or two even, if it takes that long for this to fully come to be.

When I first came to this board I was really intimidated by how quick some people will jump on the opportunity to criticize or second guess. There's a ton of knowledgeable people here, and also quite a few rather bullheaded ones

(me for one, although not on here). I'm sure we scare off more than just a few n00bs from time to time; let's not scare off this company and one of our greatest opportunities.

Hold on a second. I'm all for further development of any new device that will help this community and allow owners of their 3g to maximize their performance. If you are going to offer an industry-changing device that may revolutionize how we go about tuning the 3g, then you have to expect some questions. How many of you guys knew there was a limit to the number of time you can flash? I didn't, until I asked.

What got me was his statement, "Fuel Trims in closed has nothing to do with adjusting fuel maps unless you change 80hex which is 14.7:1 in the low RPM and load ranges.” which is categorically FALSE. Fuel Trims are directly related to fuels maps, especially when the target is stoitch or any other closed loop AFR you want to set (is you can actually change that setting). I've done it, and seen the fuel trim changes with my own eyes when you adjust a fuel map. Jay just said I missed his point, didn't elaborate, and bolted. Fasteclipse00 also noted the statement.

Our ECU costs $1081 new, by the way. We've had enough blown engines from FI apps that were widely misunderstood by the end user. The last thing I want to see is some Noob flashing his/her ECU and ...ZAP! Please understand my motivation... my loyalty is with this community.

I want Max, Jay and their company to take their time and do this right. I am optimistic, with Russ involvement; we may see something by year's end.

pacoslant · 02/16/2006, 12:11 PM

they also already have all my info and as soon as they feel they are ready they will tune my car (03 gts with a SDS @ 16psi) will (willywill) is gonna be their fed spec test car also.

so they already did an 01 cali spec with nitrous, they will do will's car (00 fed spec), mine (RIPPED) and Russ's (turboed), we should be good to go but let's have some patience.

First of all I did not bolt... If I come on here every single time, I can not get this project done. So I will let Russ handle the questions on the board. Now back to the fuel trims. Let's take the Mitsubishi EVO for an example. Which fuel and timing maps work the same as you guys 3rd Gen. When you put exhaust, intake, more boost etc.. on a EVO, the fuel trims never change. The only reason it would change, if you put bigger injectors, or use some sort of piggyback system, that changes your injector pulse width or MAF signal. Usually EVO owners don't use piggybacks because there ECU can be flashed. I know how your ECU work, I spend countless hours going thru the code that looks like this:

mov.l @(h'C8,pc), r10 ; [0003706C] = unk_0_2DDCC
jsr @r10 ; unk_0_2DDCC
nop
mov.l @(h'DC,pc), r0 ; [00037088] = h'000088B8
mov.w @r0, r0
tst #8, r0
bt loc_0_36FC6
mov.l @(h'1C0,pc), r10 ; [00037174] = h'000089EC
mov.w @r10, r10

So I can see how the ECU works. So if you a putting just a cold air intake, and headers, downpipe etc... Then your piggybacks are not doing there job correctly, if you need to adjust cruising fuel adjustments. So my point was, once you can reflash your ECU correctly, you wouldn't really have to worry about adjusting your fuel trims. But you are right, sometimes you may have to, if the mods are a big change to the engine performance. But for minor intakes, downpipes, exhaust systems, it shouldn't be no need to adjust cruising parameters in the fuel map. So I understand where you are coming from, and I hope now you understand where I am coming from. So it's no need to:

at me.

P.S All types Flash memories have a limit of erase and write cycles. Sometimes in the hundreds or thousands. Not just a 3rd gen ECU

zeeshan · 02/16/2006, 01:06 PM

Keep up the good work guys! We all appreciate it, even if you have been bombarded with questions and the occasional criticism here and there

Unfortunitely my car started to run lean. Most likely because I am 3500 or so feet higher than where the car was tuned. Jay told me this might happen before he reflashed it, so he's gonna fix it when I bring the car in. I have a safc for nitrous, so I just richened it up 15% and it runs fine for now.

ok so I went to mynes yesterday and Jay worked on my ecu for a long while, the ecu now controls the 440cc injectors and the idle is very good, I can drive it around with no problems (no boost) I am going back today or tomorrow and we will work on WOT and part throttle with the emanage still controling timing, then on the next session we will finish up the timing and we should be done!! this is what he's thinking, it might take a little longer but good news so far.

That is very good news!

repforenzo · 02/23/2006, 03:42 PM

Sweet!

pacoslant · 02/25/2006, 12:00 PM

so I haven't had time to go back to mynes, I'll try to make it on Mon. I forgot to ask for a datalog showing stock timing, can somebody please post one. Also we did a baseline and I got 288hp and 271tq @ 14psi on their Mustang dyno, Jay is very confident we he can get a lot more out my car when the flash is finalized.

About the current flash on my car... idle is excellent with the 440s, no more up and down on the rpms, it idles like stock and the driveability is great. I can't wait to get this thing done. Pics, dynos and a video will come when the car is done. Post the log please showing timing, it will make it easier on Jay.

Here's my OBD log from my V6 Galant with AEM Short Ram - would this be helpful?

paco has a 5 speed

jaytech · 02/26/2006, 10:18 PM

Just wanted update everyone on how the tuning process went with pacoslant's 03 Eclipse. My first challenge was telling the ECU that this vehicle has bigger injectors. Which are 440 cc using the stock fuel pressure regulator. I rescaled the injectors to the right size. Now the second challenge was telling the ECU the injector opening time vs battery voltage since bigger injectors take more time to open than a smaller injectors. So that was done. Now the third and most hard challenge, is telling the ECU to operate like a turbo/supercharged vehicle. Since pacoslant's car has a supercharger, and most of all... it's blowing thru the Factory MAF making tuning very difficult. His MAF signals were going crazy making the idle very unstable and stalling. So I had to resize his MAF similiar to Mitsubishi EVO in the MAF size scaling map. Also had to use more filtering in the MAF Filter table. Also had to change the scaling in the MAF sensor look-up table, and adjust the MAF tweak table to smooth out the MAF signal and to read like a turbo/supercharged car.

I haven't touch with timing or fuel maps yet. We will do more this week.

Thanks,

Jason

...so you can actually adjust the MAF table and signal to make it run like it's a stock turbo/supercharged car? That's...just plain sweet.

I can see the aftermarket for these cars simply exploding when this all takes off. They've already got the looks, and now, if/when the potential of this reflash is fully realized, it's just gonna be awesome - both for the V6 and the I4.

jaytech · 03/05/2006, 05:36 PM

I am working on the user-GUI software. Here is screen shot of the progress:

repforenzo · 03/05/2006, 06:46 PM

Cool, Jay. What are we looking at? Obviously the grid contains AF ratios. What do the x-axis and y-axis represent? Thrtl pos. and engine load (rpm)?

jaytech · 03/05/2006, 06:58 PM

The top is engine load% the side grid is RPM, but I didn't define them yet in this screen shot. Sorry about that.

wow took me about 20 minutes to read and "search" some of the terms i didnt understand...
This looks very promising...
I agree with mozart on what he said... after this i think the aftermarket for these cars will take off, once the product is finalized and released...

Keep up the good work jaytech... I guess that i would have to go somewhere else to get mine tuned by them cuz I KNOW THEY WOULDNT SEND SOMEONE OUT TO INDY lol (even though we are the FREAKING RACE CAPITOL OF THE WORLD )

repforenzo Stage 1 SDS @10 psi! Join Date: Apr 2005 Location: Crofton, Md. Vehicle: 2003 GTS 5sp. Posts: 2,278	That's not true... if your fuel maps are designed for a specific application and you change it (with CAI, headers, etc) your fuel trims will be off in closed loop. I found that out when I installed some long tube headers and eliminated the EGR. My fuel trims went from right on, to leaning out on what was once a good map. Since I've changed variables, the map is too rich for stoitch (14.7:1) Here my current averages for a 2700 rpm closed loop cruise, both short and long term (Bank 1: Short Term=-3.1 Long Term=-7.0 Bank 2: Short Term=-2.4 Long Term=-6.3). Now, that isn't bad, but the original map is now rich to maintain 14.7:1 without have to pull back the fuel trims. Maybe I'm coming too much from the piggyback unit side of the argument... But along with observing you EGT, AFRs, Timing, etc. in a WOT situation, it is almost more important to have the closed loop operation as close to stock as possible... At least that is what I've been told countless times. Not trying to get in any pissing match here at all. You definitely seem to be an authority on these ECUs and I definitely want to see your product realized. The basis for my arguement is that my friend used the Split Second program to change his fuel maps in his ECU to get zeroed fuel trims... he's got a supercharged Toyota T-100. Thanks.

The rest of you guys... please relax. I know you all are excited about this but we are really onto something revolutionary and they are willing to help. I spoke to Jay tonight and he will no longer be posting on this website. So if anyone has any questions about their products please route them through me. I will be providing you all with periodic updates as they come through. __________________ Russ Sanderlin - Twitter - Facebook - Blog Mitsubishi Eclipse - Generation Gap Eclipse Tech - New 5G Eclipse - 2006+ Eclipse Forums - Mitsubishi Mid Atlantic - Mitsubishi Florida
