ECMlink Maf com problem?

[newdsmtnr96]

Does this look like a maf comp problem? When I transition in to boost It acts like a fuel cut, It goes lean for a second then SUPPER RICH where my wideband flash's 10:0 . I have yet to find a log of what a boost leak looks like on here. Maybe I am searching with wrong words. Has any one seen something like this?


I just replaced my clutch and I dont think anything has to do with it.

Most people don't log boost leaks...they test for them and fix them.

Your MAF comp curve is way out of whack. Why have the DA tables been modified when nothing has been done to get the basic air/fuel calibration done?

I suggest you go through this: http://www.dsmtuners.com/forums/ecm...efore-you-ask-ecmlink-dsmlink-log-advice.html

...and then reset everything to stock and spend some time reading as much as you can before diving in to the ECU and tweaking things.

one thing is you have disable maf comp with SD operation checked your running a maf and your disabling maf comp

That option is only operational when you're actually using speed density.

It has no effect when using a MAF.

Also, I'd zero the fuel sliders and only tune with the MAF Comp sliders, once you get global and deadtime set.
