ECMlink Unable to effect fueling..

[DSM IN MN]

We've got a '93 TSi AWD with 1,000cc PTE injectors, a 20g, HKS 272s and a few other things done. Our issue lies in the fueling. No matter what we do with 'link (V2), we cannot change the way the injectors are acting. The car runs around 11.8ish-12.6ish according to the AEM UEGO. No worries on the AEM; it should be getting replaced soon.

So far we have turned the fuel pressure at idle down to 37-38PSI. The setting in the ECU are as follows:

Global fuel -51.2%, global deadtime 450.
0 -10.2, 500 -15.6, 1000 -16.4, 1500 -10.2, 2000, 2500, 3000 are all at 0.0, 3500 +5.5, 4000 +7.0, 4500 +8.6.

We are unable to drive the car very far due to the hella' rich idle so we do not know how it behaves on the upper. We have mostly messed with the 0-1500 as it was giving us a high idle issue before.

Is there any sort of suggestion one can give us? Our next step is to look for a boost leak. We spent most of today sourcing and making a tester. Our main hardware stores were closed so we were stuck with Wally-World and a Fleet Supply. Of course I left my tester at school!

I'll get back with the results of the BLT and hopefully a log as well.

Thanks!

***Edit: Car is running on 91 octane.***

Do everything in this list:

Once you have, you should have your idle dialed in. The ECMTuning videos will help walk you through this (adjusting MAF Comp sliders to get AirflowPerRev in check and adjusting deadtime to get CombinedFT in check). If you get stuck or run into issues, post a log.

Thanks for the link. We found a few boost leaks as I anticipated. Old vacuum lines, makeshift coupler(s) & shaft seals. Not to mention he has an exhaust leak due to the following; he's running a full thickness manifold flange behind his manifold, then a Mitsu. to T3 adapter plate for a Hahn 20g. I want so badly to get a different manifold for the car but the one he purchased "won't work".

Time will tell I guess. We will work through that list then see what we have. Thank you again.

Here is a quick idle. Injectors are set to 2113cc, Global -78.1% and Deadtime 1245.

Any sort of direction would be great.

Disregard that log. We watched a Demo video on the ECM site and I realized we had some stuff way out of wack. Working in perfecting the idle again no. No TPS signal as well even though the sensor is new.

Lol The joys.

Do you have the tps wires hooked up and, in good shape.
