Help me tune please!!!!

When I did my TT swap on 10:1, I used a TT ECU, a wideband and MAFT Pro. With the TT ecu there wasn't much I had to adjust on the MAFT Pro to get it running well on wastegate. I would think a TT ECU would help the most, but in reality, to do it right, you need both.

BTW, did you figure out how to post logs yet? I'm curious to see what the NA ecu does with boost.

I'm goin to get those up ASAP. I have to get a adapter for the cable to hook up to the computer. Which ecu do i need? 9966 or 9965? I might be able to get a good deal on a tt Ecu.

ECU should match the harness and the Cam/Crank sensor set up and whether you are cali or fed. Usually fed will be the way to go. You said first gen, so you would want a 91-92 ecu for a single cam/crank sensor and a 93 for separate sensors. I think 9965 is cali 91-92 and 9966 is fed 91-92.

I ran a cali spec ECU just fine.

Either of them should work but try to get a 9966

0663 should work, you'll just have to do some work with the radiator fan system.

I'm a 93 so they won't work for me. I'm ordering a wideband and tt fuel pump ASAP so hopefully I can get this worked out. I think I'm get the lean missfire because the narrowband o 2 is trying to lean the car out at wot. I also found how to get the logs on my computer but its a spreadsheet. Can't I just unplug my narrowband and just plug the wideband in and tune off that cause I want to do away with the narrowband altogether.

You can. That's what I do.

IIRC the ecu doesn't use o2 sensors at wide open throttle, only maf and tps.

Can your tps go bad? Or can not having the tps adjusted write cause problems. Because I know for a fact my tps is all off and I really didn't think this could effect anything.

your TPS should read around 13% at idle, and about 98% at WOT, roughly,
