ok so limit has been raised and now i'm throwing the damn implausible maf signal but not dropping load/ running super lean. It does however change the drivability of the car.

Below is what i THINK the culprit is:



There's normally a word for byte for max voltage, have you adjusted that?

I'm not sure I understand what you mean... "Word for byte"? My volt max is 4.9.

I hit this error regardless of boost level even at 5psi.

Meant to say or not "for" sorry Smiley

There are ML limits too haven't explored that side much though.

What is maf voltage and ml when you hit the code?  compare against limits in file?

I'm using me7logger and I can't find MAF voltage so I can log it...

You can back calc it via the curve then or use IDA to find it.

KFMLDMX is signed. What hex values populate the map?

No more midrange errors.
Also, MAF max (mldmx) has plenty of headroom as seen in this snapshot but is still it cutting load. However it is NOT throwing an EPC/CEL light.

What's knock?  Injection time seems to drop from 14.5 to 10.5 pretty quickly, why?  Also, why is lam 0.66.  Surely that's black smoke time?

knock is around .75~1.5

Injection time drops with load suddenly, that's what I'm here to figure out.

Lambda is rich however O2s read about half a point richer than actual (rear turbo car) due to exhaust pressure

Also injectors aren't fully dialed in according to my fuel trims.

Could be ATR, logging time!

Could be a lot of things!  What is your lower lambda limit?  Why is it going that rich, etc..
