You are talking about the 400% load in the timing maps. Those maps have it built in, but the ECU will not go up there. The range is set. The most I've seen "ECU Load" in EVO scan report is about 96%.
Well, She's (SDS) in...

The most the "load" column will show is about 96-99%. . . Look at the "load Calculated" column and compare the timing and fuel trims to the 400% column. . . .that'll tell you what column it is pulling numbers from :bigthumb: (what i found out. . . .also posted up a log in the 3.5L thread)

Sorry bud. You are wrong. The ECU does not understand load over 100%. PERIOD. The code in the ECU is written for a 0-100% scale and that is it. The 400% you see is a safety margin.
If you want to test this, try rescaling your tables so that 0-100 is in the first half of the columns. Then go 130-160-190 etc on the remainder of the columns. Go do some datalogging and report back what you find. What you will see is that the only thing you were able to do is decrease your resolution.

:agreed: It is unfortunately the case. The sensors (MAF etc.) 'see' boost are report to the ECU their data. The ECU just does the calculations like it is still n/a.

I know what you are talking about, but that field (like others) is just the EvoScan doing its OWN calculations. Has nothing to do with how the ECU is calculating. ECU LOAD is the real deal.
Like I said before, the sensors on the car report the proper data while a car is boosted. We share many of the components with the EVO. I looked at some of the Load Cal fields and the data doesn't make sense in the real world.

what if you get rid of the mas period. Wouldnt the ecu have no way to calculate load. My intial plan is to use the maft pro with speed density. The speed density allows me to get rid of the mas and replace it with just a gm map and air temp sensor. Im not sure if the ecu would still try to correct itself

All the maft does is translates once type of signal (GM hotwire 0-5 volt) to another (karmen vortex). The ECU receives the same signal it would as if the MAS was there. So as long as the MAS is metering accurately and you have space for it, there really isn't a need to switch.
Most the the evidence points to the 3G MAS and EVO MAS being very similar. We really haven't seen examples of it being "over run."

Its been a on going fight but people have tune our cars with piggybacks before the flash came out. It just requires time and patience.

Right. Plus the key with piggyback is to not try to go too large with the new injectors. Cutting the airflow signal by too much is just asking for trouble.

I don't look at it as a fight. I can tell the ECU to do what I tell it. The issue is the parameter range is not correct for boost. Once that changes, the sky is the limit.

Ok, I've ordered 42lbs (441 cc) injectors. They are getting flow tested as we speak. I'm hoping Greg will have some good news for me when I come back from my Las Vegas business trip on Thursday.
was talking about that with a buddy of mine with an Evo, as far as either of us were able to see, they are pretty much identical, and word in the DSM world has our MAS being an upgrade for the 1g and 2g

Well, I'm still waiting for my heads to get done. I have one more business trip to LA that will take me til June the 4th, and by then hopefully Greg will have good news for me.
The down time is not a good thing. It is making my car an afterthought. I saw a nice dark blue Z06 and I wanted it. It was the first time in a long time that I felt passion for a car other than my own. I've got to get it running soon, or the desire to get rid of it may take over...
I'm hoping this feeling passes, but having a car sit on jack stands for a month and a half does not endear me to it. I suspect once I get working on it again, I'll feel differently.

i know the feeling i was really close to selling my turbo kit and car last year. But i kept it and im back working on it. But aside from that i have a question regarding the ecu limits. Ok we all that ecu is strict and cant read over 100% load but the timing function works great with ecu flash. What if we use megasquirt ems to control the fuel and read load while we use the ECU flash for timing.

Just as I'm starting to feel sorry for myself, I find out the heads are completed. I've already paid for the repair and will pick them up from Greg on Sunday.
Installation will have to wait until I return from the west coast on the 4th of June. Once Greg and I set a date to put the heads and timing belt on, the rest should be a snap.

I know how you feel but since I picked up my car today it was better then before.Just as I'm starting to feel sorry for myself, I find out the heads are completed. I've already paid for the repair and will pick them up from Greg on Sunday.
