Just wanted to add a note relating to DBW and idle hunting (based on Kris's input also).
Under DC Motor | Pedal Position - I changed the Pos 4 breakpoint from 192 @ 9 degrees to 196 @ 9 degrees based on the Monitor ADC realtime values for "Exhaust Pressure" (assuming this is a free channel not used normally and is now setup for DBW input/output). I noticed that when the car is not running Exhaust Pressure/aka Pedal Position was at 192 bits. But when I start the car it's at 196 bits with occassional drops to 192.
This change has helped remove some of the idle hunting, but I might need to adjust fuel in addition to get it perfectly smooth.
I also adjusted the Air Temp sensor calibration and Water Temp calibration as they didn't appear to match real world temps. The Air Temp was as much as 7 degress C off what I tested. I'm gonna dare suggest that calibration of these sensors is critical BEFORE any tuning is started.
Now the scarey part for me (just not enough knowledge yet). I installed NGK wideband and did the pin change to support Lambda 2. I loaded up Phil's Lambda 2 values as he is using the same NGK wideband. However, the car under load does NOT like the Lambda 2 values. Now here is the scarey part, if I switch back to Lambda 1 the car runs great under load.
I would love to get some Lambda 2 hints.
I have to say, I'm kinda enjoying this.
