Was on the dyno checking AFR. At 4000 it was 12:1 so added 5% to the PE table @ 4000. No change in AFR. Then added another 10% then 15%. Still no change. Everywhere else I had no problem changing the AFR.

What am I missing?

adding to would make it richer

Ed,

What are you PE enable setting (MAP, TPS%, RPM delay)? Was this a WOT dyno pass and what kind of dyno?

Ed Blown Vert

TPS is 26%, RPM delay is default (and I understand it has no effect). MAP is also default. It must be going into PE, otherwise why would go to 12:1?? Didn't have the problem on the last engine.

WOT pass on a Dyno Dynamics and DynoJet

And yes I do want it richer.

What injectors are you running and how much power are you making?

Mototron 60#
Numbers in sig

maybe check OLFA tables

What about fuel pressure? vac/boost referenced regulator? Did you log the inj duty cycle?

Never seen this problem before unless the injectors are maxed, but it really doesn't sound like they would be on your setup.

Add some fuel via the VE table..........

FP started @ 60# and dropped to 50# (Ractronix FP). Injector DC was if I remember correctly 75% @ 6500. No referenced regulator

I know they are not maxed out, didn't have a problem dropping the AFR @ 6300 from 12:1 to 11:1

why not logged commanded afr to see if its at least attempting to go richer

What is your enrichment rate set at? That has a big impact as to how quickly it ramps into the extra fuel...max rate is 4.0 (where mine is).

Ed Blown Vert

Next time I am on the dyno, I'll check commaned. I didn't touch enrichment rate.

what were your iat's

Ed Blown Vert

iTrader: (2)

I'll have to check the EFI log, but I think around 100

This is why I told ya to get a better fuel setup. Or at least a FPR with return at the rails.

Celsius or fahrenheit

I don't have my software with me to check, but for some reason I *think* I recall seeing a parameter that limits max enrichment. I could be talking out of my *** too.

I only have this issue @ 4000 rpms. Everywhere else I can change the AFR.
