Subject: Co Trim not saving in Guzzidiag Mon Sep 14, 2020 2:43 pm
Loaded a new map 2 days ago with Guzzidiag suite. All went well, reset tps, learning parameters and Co Trim. The mixture turned out to be over rich and so today I attempted to reduce the Co Trim value. All seems to be Ok but the reset value doesn't save. I've tried everything I can think of, 3 different versions of Guzzidiag and removing and reloading the new map. Help please on how to achieve/force a Co Trim change. Many thanks, Mark

I have seen cases where you need to wait ~20 seconds between setting and saving, for the value to "take". For example, if you set CO trim at -3, wait a minimum of 20 seconds before saving. Then wait another 20 before killing the engine, etc. A pause between steps.

Beetle, tried your suggestion but with no success, setting still not taking. Any other things that I can try, or alternatively is there some way of editing the Eeprom that would solve the problem using the eepromtool?

It can be edited with TunerPro. Beard made an XDF for the eeprom.
