I don't mean to revive an old thread, Its been over a year but I'd like to reinforce what you said, the deadtimes were extremely low. The correct values were as you stated. Although its been some time, just wanted to extend a formal thank you for taking the effort to review and provide input. The ...

Would anyone be so kind enough to share how they approach starting and idle fuel for speed density based calibrations?

Background to why I’m asking:
I’ve made a custom turbo kit. 1,000cc injectors, dw65c. Gt3076. Nothing radical, on a stock k24z7, original engine in vehicle.

I’ve already dialed in ...

Background: I've been trying to dial in a MAF based calibration for about a week and I think I've got it pretty close, there are some slight fueling issues up top at WOT but nothing too bad as this is a MAF based cal. (will be going to speed density pretty soon once I get the vehicle to run as ...

I’m learning and trying to tune a stock car with just a resonator delete.

Intake is completely stock, down to the airbox.

When I idle, the vehicle would stumble/stall a bit and my physical interpretation was maybe the resonator delete results in less back pressure so the fueling at idle is ...

Check for exhaust leaks, if there's an issue with your O2 sensor, the datalog readings for fueling may not be completely accurate.

I can tell you what I THINK based on what you provided and my reasoning behind it.

You have an aftermarket intake and exhaust.
Your speed density min is set to -14.7, (You said it was full speed density before however, at idle/part throttle, your MAF sensor is controlling the fuel supply with ...

Alright, so since the ecu is locked to a different Flashpro, I would then have to purchase an additional Flashpro (that is not locked ofc) and then I would be able to revert the married ecu back to factory on my own? Or would I have to send in both units so you guys can properly do everything?

Background: I am doing some mechanical work on an SI for someone I know personally and the owner bought the vehicle but has no idea about vehicles whatsoever. It is NOT stock at all but it is tuned, I know it’s not on KTuner because there is active launch control on the vehicle, and I am sure this ...
