Current problems I’m having
Car runs fine without the quarter horse plugged
Throws a check engine light for egr being disconnected
But if I plug it in and it’s loaded with the a9l2 tune the check engine light flashes really fast and it does not run well I’ve tried redownloading the tune but still the same thing
I’m also having problems with getting my wideband to show up on the data I’ve tried ever guide I can find still no luck I’ve check the voltage and I have it tapped into the correct wire on the ecu connector still nothing

im really about to give up on the quarter horse and go to my tried and true delta force software the data logging might not be worth all the headache

I’m running the a9l2_240103.bin gufx_240206.xdf and the decipha_230417.adx

You'll need to post your tune so folks can see what's up with it.

The tune is the straight up stock a9l2 no modifications made to it yet but I can post it if needed

if the check engine light is flashing that means you have a major problem

should be obvious on the dash as something should be red or not reading correctly

wideband logs automatically no setup required

simply right click on the wideband on the dash and select your wideband from the drop down list.

I have no idea about delta force but have found QH and TPRT so simple. Complete plug and play. Absolutely amazing for what it does.

Have you tried just running a stock A9L tune? Is your fuel pump continually priming when you hit the ignition? If you can’t get it running, could be as simple as the tune not being loaded.

So after many hours of diagnostics found out the rebuilt ecu from sia electronics that was in the car was faulty and causing all my problems I put a a9p from ecu exchange in it and it’s all good now logging the wideband no more flashing code light now I just need to figure out how to make the history table stream line adjustments

it does automatically

simply poll data with the histogram opened in the background and itll populate all your corrections

The stock tune is for 19# injectors and you have 24?
