Looking for help with my tunes. Mostly boost controls but if you have any suggestions or advice on anything else I'm all ears. I can't get this truck to make more than 30-31 lbs of boost. Mods are...

Anyone?

I have been over the tune ten times and I can't figure out what is limiting me. Trying to set my WOT shift points at 3600. Something is limiting starting at about 3300-3400 RPM, then the truck will...

I re-read over the post and followed the advanced summary as well. Not sure if you can tell much from a log but I'll post it just in case you're able to see whether it's right or wrong. I've logged...

I have all my pids selected and logging. Is there anything that needs to be done to the tune before starting? Does it need to be in speed density like the auto be method?

Also with this file the car stumbles when it enters PE. Are there any adjustments that need to be made to use that operating system in an older car?

12212156 is the OS. Here's the screenshots.

Okay I found the GM.EQIVRATIO. I realized that maybe I should connect to the PCM and see if it showed then. The Dynamic Air Temp DAT shows valid, however, Dynamic Air Temp DYNAIRTEMP_DMA is showing...

I cannot find that pid in my scan tool.

Pid file and calc txt file

Dynamic Air Temperature gives errors PID value cannot be determined because the following error would occur: Expression not valid: Unknown parameter {GM.DYNAIRTMP_DMA.C}, at position 21. And two...

My Scan Tool is giving me some errors with certain pids on the calc pid file. Ben From WB, Closed Loop, Dynamic Air Temp are all X.

Hey Joe, I getting ready to start this today. I was wondering what the difference between this and the calc.maf reverse process was and whether one is better than the other?

Is this the best way to wire direct?

Joecar, when wiring the serial cable for the wideband is it possible to just wire a direct cable? What it the purpose for the adapter?

I'm measuring about 0.15V. If I bring a ground wire from the battery and tie into the wideband will that help? I am going to search for the null modem procedure just in case it won't.

So what build dates have it?

Do all the CM2350B controllers utilize the SGM or just some?

So you would just check your battery ground vs. wb ground? How much difference if any is acceptable?

What are the ground offset issues?

Also thanks for the help. This is hopefully going to be a big improvement for this and a few other builds I have.

Okay I have the 2002 file and have adjusted the engine displacement, speedo, etc... Is there a benefit to using serial connection for the wideband or will analog do the same job? My wideband is an...

The car is a 1999 Trans Am but when I found a stock tune file for it the OS matched that of the 2000 Trans Am from the dropbox.com of gmperformancecentre. The engine is a 383, mild cam build. Is this...

I have read over the sticky a dozen times and I still do not know what I am suppose to be doing. I can follow what pids to select and can configure data to display in different units. But when it...

Ok, thanks Joe.
