Ok , Thanks for your help.
Well, I drove around yesterday and burned a tank of fuel. I took Removebeforeflight's advice and removed the wastgate actuator. I was really able to get the ve tables in in those 100kpa cells.
My laptop died right when I was about to hook up the actuator and take a ride and datalog.
Got a few more days on it. Still chasing some random knock counts. Going to have to check the knock sensor torque. The 3" DP and exhaust have plenty of clearance. I don't feel/hear anything rattling.
Is there a setting that turn the air off after x amount of TPS or AE or PE? My AC compressor cycles off with hardly any throttle angle, at any gear of speed. I've just redid the entire AC before driving the car. Pressures are good, high is not too high, and low is not to low. I've adjusted the low pressure switch since I am running R134a.
Take a look at a data log of this. As for stopping A/C, there is a flag when set to kill it when in PE mode. PE mode can be entered via TPS% vs RPM or MAP KPa vs RPM:
Option Word 3 - Bit 3 - A/CPe
PE - TPS% Enable Threshold
PE - MAP Enable Threshold
There is also a high RPM A/C cutout:
A/C - High RPM disable
A/C - Low RPM Enable
Thank you sir, after looking at a log, that is what's happening. The ac is turning off when going into PE, and it's the map PE. Now, I don't think I want to change the TPS and MAP PE tables, so maybe I'll uncheck that flag, and just use the RPM table.
I thing my EBL classic used that routine to turn off the AC, just and RPM window. You'd remember better than me.
The Classic didn't have the MAP enabled PE table/function. And there wasn't a flag to allow the A/C to stay on in PE mode.
The above mentioned option flag just changes the A/C so it stays on when in PE mode. Another thing you can do is to increase the MAP PE enter values.
Thank you! Great info. I think I'll try just turning off ac/PE flag.
