Re: Idle Issue
yea ACT is a global fuel modifier. ACT is part of the fuel mass calculation.
Lambse is commanded fuel, commanded won't change.

Re: Idle Issue
Perfect, not crazy and am on the right track lol!
ill report back after I wire into the Pro-m IAT thermistor and hopefully it clears up the factory located ACT issue.
I feel like at WOT the EV6 injectors are causing a bit of a mist that may be reverting back onto the sensor as there only 2" away from each other but also may just be a shit sensor!

Re: Idle Issue
Is the ACT global table defined ?
Is it a table or more of a scaler

Re: Idle Issue
Ah so no tables or modifiers and just part of the calculation.
Working on it now!

Re: Idle Issue
Once I hook up to the IAT in the MAF is there a IAT transfer function that needs scaling or is it close enough ?

Re: Idle Issue
Ok IAT sensor is hooked up in the maf now instead of ACT and it seems to be reading just fine but still the issue remains on hard accel or WOT something is messing with the signal. Wiring issue, EEC issue? WTF Log attached
Guess I could start with an overlay of wiring directly to the EEC, possibly a broken wire or partially broken on the signal return.

Re: Idle Issue
Well there ya have it, Ran an overlay for the sig return and no change and figured I would check the 5v and sure enough its dropping on the voltage side of things. Overlay to the EEC on both wires and now IAT is reading correctly!

Re: Idle Issue
I noticed this guy has a TB spacer that necks down to approx 50mm from the 75mm TB. Anyone think this is a big enough restriction to validate lower then anticipated rwhp numbers?
