Ive noticed the fuel pressure driving around warmed up is around 24 psi.. I did a key on engine off and that showed like 33(cold). So my thought is the FP is not adjusted correctly .. I just bought this vehicle so I have no inclination of whats good. It seems to run great so im kinda reluctant to adj anything.. but If i need to just let me know your thoughts as I realize I am the student and you are the teacher...The run itself looks good.
But your BLM's are low which means the computer is compensating for a rich condition. You can see that almost all the cells are 118. I've found that is usually caused by a bad MAF, or the chip is not matched to the injectors, or the fuel pressure is way too high. This is not the end of the world, but something is going on there.

Here is some of whats done to this car. Im sure many of you know this car already as I bought it off a member here that goes by SS502.If you are happy with the way the car runs, then you can leave it alone. But something is off, and your fuel pressure is way low. You have some knock in that last log, and a big boost spike.
I would check the part# on the injectors, then give me the info on the chip. It almost seems like they are not matched.
I'm assuming you're running alcohol injection in order to run that much boost.
I am going to personally verify the part # and the chip info. Would you say that I should start with the first run .dat and tune from there or start with the last 27# tune if the chip is indeed matched?If you are happy with the way the car runs, then you can leave it alone.

On the MAF BASE setting, I can't see what number that is. You might be able to make a small tweak to help the BLM, but lets see where its set right now.
I recorded the numbers off the maf, they are : Delphi 25168491On the MAF BASE setting, I can't see what number that is. You might be able to make a small tweak to help the BLM, but lets see where its set right now.
The number closest to the red mode box in the translator is 6 or 9. and the other one is on 1
Very good thank you sir. We have rain the next couple days so the car is garage bound for a while till the sun comes out again. I will Change the setting to 8 then reset the ECM. And report back the new BLM grid.That's the 85mm MAF, and "6" is the normal setting. But I would set it to "8", which is slightly leaner and should help the BLM's a bit. It will not affect full throttle performance.
So, change the MAF BASE to "8", then reset the ECM by disconnecting the single orange wire by the battery. That wire comes off the positive side of the battery and has a single connector. Resetting the ECM sets all the BLM cells back to 128 so it can start learning again from scratch. Then after a day or so of driving, lets see what the BLM grid looks like.
