calculating load stopped at 150?

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

calculating load stopped at 150?

Post by midnightman » Wed Jun 06, 2018 12:17 pm

Guys,

I have little problem with EEC-IV cosworth.

we sorted cheating MAF, now maf is reading like hell 700Kg/h but car wont calculate more than 150% load!

look at picture...please..

load is going up...then when is load 148....it will continue with 148...straight..
=
low PW....less fuel...and you can see real AFR blue pen..going lean cause air is comming...fuel not.

is it point where ECU is in limp mode?

or what can cause this?

I have more logs...where LOAD stucks on 150...

I don't know if this is related, but this sounds similar to an issue I remember from years ago in GUFx stuff related to the Airflow Max vs RPM Clip (FN037) function. Raising all right-hand column values in that function to their max fixed the issue I'm remembering.

I don't know that this issue ever manifested as you have detailed here though.

GHAJ0 strategy, there is no FN037 :(

Can you log ZFAR and FLAGS_2 as well.

Comparing logs, your larger exhaust turbine VS OEM has significantly changed the relationship between MAP and VMAF/LOAD
As part of failure management, the EEC cross references inputs and calculations. When reality is too far from software, default values are applied.

I see you have adjusted WG desired load to a big number across the board. Return to some realistic numbers the turbo/engine combo can actually do.

You may have fallen foul of WGLODLIMF, by putting in desired load values that the turbo/engine can't deliver.
Adjust FN530
Try adjusting FN1036A
Have a look at VMAF at 52.662 seconds in the log and VMAMAX.

What was your reason for changing FN532?

Put BPMAX back to the OEM value.
Cheers
