Perfect, thank you. I figured it was likely just a tracer issue and not an ECU issue.

RB20 ECU on 11U0H rom. So first is the question, and how exactly are these tables used? Are they referenced when the fueling map is in a closed loop cell? If so, are they reaching out to previously learned values corresponding to this table? So if I'm right, it'd be an 8x8 self learned table? The is...

Is there any conversion that can be done to figure out the amount of air flowing into the engine thru the MAF? I know other tuning programs I've used have had a built in conversion. Trying to understand how much air is flowing into the motor versus virtual dyno numbers. I'm thinking I have a boost l...

Is that board reflash free?

Also do to packing constraints, the intake cannot be any different. So the injection time is too high essentially flooding the motor, making it impossible for it to recover itself?

So I'm reviewing a log and not sure what's happening. My throttle hung slightly open after a small acceleration. I blipped the throttle and it went back to normal idle voltage, but the car never saved itself. RPM's just kept falling. It shows the injection time picking up, but the AFR's are not matc...

It would be a nice addition if the input tracer would load all the values from a lot, instead of having to replay the entire log.

If this is in there somewhere, I've clearly missed it.

Perfect explaintion. Thank you so much. I got some work to do now

I want to make sure I'm doing everything right. I saw lots of post from the past where you want to drive around in 4th and about 2k rpm, and low or raise K constant until fuel trims are in line, then start fuel map tuning. Now I'm reading some new material that suggest fuel trims should be roughed i...
