Hi, thanks for the replies. I have those idle numbers in there to disable the adaptives because I was trying to find the final airflow min via this method: ...
2011 CTSV, has a 102mm TB (china) and 4.5" CAI. Updated the ETC scalar but still getting elevated RPM until the adaptive idle kicks in. I'm trying to set the final airflow minimum like in the...
I'm having an issue I can't solve and wanted to try a known good file. Does anyone have a 4L80E swapped file for an fbody that they've used before? If I'm going to burn the credits I guess I'd...

So I actually don't see Clutch safety switch on there but it looks like Gray/Blk+white is clutch pedal position so the purple/green is probably Clutch...
Thanks but that doesn't really help me as the problem is intermittent, or I don't understand the conditions causing the early shift.
I changed the 0% TPS values in the shift table and verified the "early shifting" is tied to the 0% TPS cell, only seems to happen with TPS values from between ~20-30%. However, I've never actually...
No I didn ‘t write it down. Basically this:
Wire one side of the shifter’s neutral safety switch to ground.
Wire the other side to PCM blue 34 and pin86 of the relay.
Wire pins 30 and 85 of...
Ok I just did this. You need a relay to reverse one of the signals then you can use the shifter for both the P/N signal to the PCM and the clutch safety switch. Also, if you are logging "current...
Ok, I made a custom pid for trans speed based off the trans output shaft speed and the rev/mile value in the tune. The 2,931.6795 value from the first tune is correct resulting in a trans speed that...
I swapped in the speedo segment from the 4L80E tune and calibrated the speed for my gears/tires. I got a different value for trans revs / mile then the tune posted above. So I flashed it but I'm...
What am I missing? Seems to be shifting too early and the converter locks too early too. Seems ok at lower tps values but at ~ 25-30% it doesn't follow what's in the tune. See starting at frame...
Adding airflow to the Idle proportional airflow (low) tables fixed this for me.
you could create a custom PID and calculate from dyncylair. See attached from Marcin's blog, the units are in kg/sec (convert dyncylair to kg/cyl first) but that is easily converted to lb/min.
...
You talking about dynamic airflow? Checked some logs, mine maxes at 67.725lb/min (2000camaro). Maybe its a hard coded limit in the PCM.
You need to log the idle stuff. Cracker, follower, stit, idle desired airflow, IAC, etc. Then you can figure out what is going on. Cracker is just rolling idle. Follower "follows" TPS. The...
