I know right? More like, V6 pistons aren't able to handle a bad tune.

:agreed:

ECU Reflash no go on boost. :lol:

Still, the fuel control side has some limitations. But the dual timing maps has allowed me to go lean up top and avoid typical engine loss results.

While everything is out, I'm going to upgrade to Ford's 42 lbs. injectors. We'll also add a 6:1ish FMU.

I heard the FlashBlueRS is able to unlock the boost control. Does this only apply to the RS/GS or the V6 guys as well?

Why not just get a 1:1 FPR and some nice 440c's ?


I always wondered if the Saturated most guys are using aren't the problem, with their lag time. :dunno: Some food for thought...

Sheesh, its kind of scary that all this is happening because of the belt jumping off the pulleys, especially for someone who has close to a 5000$ motor. Honestly, i think the walls on the pulleys should be a bit taller as to prevent the belt from running off. The plastic idler pulley is a POS, not to mention it is almost impossible to line up correctly with the belt. I really am thinking about replacing it with an aluminum pulley than has walls on it. Also, me and kris have been talking about going with a high grip shaft pulley, which does have a taller wall on it and taller ribs.

I'd take a guess and say that the belt runs off either the idler pulley or the altenator pulley. Another thing i could say is that possibly the SDS shaft isnt correctly lined up (IE, locked into the slot position, which would be farthest to the driver side as possible.). This would make the belt want to run off towards the passenger side, probably off the idler pulley, and then a sequence of events after that. The ripp crank pulley does have a pretty decent sized wall on it, so no running off should occur there. The stock pulleys on the A/C and Alt are pretty cheesy for the SDS application.

Maybe we should look in to sourcing out a complete pulley swap, including ALT,A/C, Idler, and SDS shaft, all which would include taller walls. I feel this would help prevent any belt runoff situations.

Bryan, count me in if you all go that route. I am interested in cutom "heavy duty" pulleys to avoid a belt jumping off. This thread has just about scared the poop outta me.

I have an Aeromotive 1:1 already. I experimented with the latency numbers adnauseam. It is the 100% load limitation that bones us. I can certainly get enough fuel for WOT by cranking up the fuel pressure and fatting up the injector scaling. I just don't want idle to be a 10:1 or so. I think I just need to find the right combination.

I feel ya. What happened to me is just bad luck. Most shredded belts don't end up where mind did. Maybe a higher wall would help. To me it is the pressure the Vortech and the SDS shaft put on a belt. The ribs on the pulley are like razor blade that cut deeper into the belt and over time, one belt becomes six smaller ones.

It'll be hard to get someone to source this car.

Don't be scared, as I said, it was some bad luck. But it comes with the territory. Once the SDS is in, you'll be still working on the tune and such.

Actually, I kind of enjoyed pulling the motor apart. This is not a hard engine to work on in some respects. The engine bay is not near as restrictive as some bays I've seen.

It is the down time that annoys me. Ok, and maybe the cost... But this is nothing compared to some of the disastrous situations I've seen at the track.

 

[Clipse3GT]

If we could get a idler developed that puts on a constant load that would help. Without the damn belt bouncing around like on the spring one. Or modify the current tensioner to put a constant pressure on the belt. That way you minimize the chance of your belt hoping off the damn pulley's.

I know your trying not to use a piggyback but wouldnt that help you in your situation

The flash isn't the end all answer for boost. Only if you are a 5spd RS or GS that can flash to the EVO ROM. That is the only way your ECU will be properly setup for boost. While Phil has done a remarkable job of getting his car to run good with the reflash, you have to remember he is doing all of this in open loop. If he had to enable closed loop operation he would be stuck in the water as that becomes a nightmare. That was part of the problem w/ the SDS car I've been working on. I needed closed loop so the car would pass readiness tests for emissions. The car won't do that in open loop only.

So yes, the flash is NOT the complete answer for boost tuning. It can definitely play a major role depending on your circumstances but it is not perfect nor complete.

There is NO boost control whatsoever even in the EVO ROM. The ECU doesn't see boost, it just can understand load greater than 100%. Our ECU's are limited because it doesn't understand anything above 100%. Hence the reason our ECU's suck ass.

EMS for me FTW!

 

[thahnic1080]

So if someone wants to pass emission would it wise for them to flash the car so open loop comes on earlier for example part throttle. If your running ems wouldnt you have to worry about obdII check for inspection.

 

[PharmEcis]

Phil basically has closed loop disabled so he is not passing the readiness tests. He does have another map he can reflash back to for emissions purposes if necessary but it is strictly for driving like grandma.

An EMS will not pass emissions because of no OBD-II. That being stated, that is still what is going into my car.

evo 9 ems. Im suprised he didnt know about it before.

I do have an e-manage. Greg is tuning a car using the flash for timing and the e-manage for fuel. So that is definitely one route to go.

I haven't left every stone unturned yet. As Greg said, I'm running in Open Loop all the time, and I'm still going to try to get back to some sort of Closed Loop operation for idle and cruise. But if not, I do have a tune that has zero fuel trims in closed loop that I can use for emissions purposes.

I think it is time to post something on the OpenECU boards and see if Colby would attack the 100% load issue one day.

 

[thahnic1080]

Yeah me and my turner were discussing this issue but he said having the ability to make the car run open loop all time is great (in his opinion). Maybe colby could do something about the load but i believe it has to be a high demand on it. Or possibly flash could do something.

FlashBlueRS is not interested in tackling the 100%, primarily because he has a RS and can flash an EVO ROM whenever he goes FI. Not to mention it will be a big undertaking. Colby may have to do this.

 

[MarkSpyder]

Perhaps we should start a poll to see how many people would be willing to pay a good chunk of $$ to get this done. It seems to me that the 3G ECU needs to be able to read loads above 100% in order to be a completely tunable car via ECUFlash & logger only. Are anyother parameters required in order to only use ECUFlash on a boosted V6? I'd be willing to put a few hundred+ into the project. I'm not keen on the idea of using the BRAT and that other "half assed" stuff. If we can move to a laptop and tactrix cable alone then that would give me a BIG piece of mind and I am willing to pay for that. Would be good to have an idea of who all was interested and how we could make it worth Colby's time before approaching him about it ??

 

[thahnic1080]

that would be a good idea but how many FI cars are out there. Theres not a lot to get it moving in my opinion. Im willing to pay though

 

[Dragon34x]

The ecu CAN read loads above 100%. . . .the thing is "tunability". One column on our maps for any loads over 100% is all we have. Like you've seen repforenzo, it will read loads over 100, the thing being tunability is extremely limited.
