Hey guys. I'm stuck on the opposite coast as my car, otherwise I'd just go out and experiment until I got things to work. I'll have some car time this weekend, could someone point me in the right direction with regards to the questions below?


I have a set of 750cc injectors waiting to go in, but it looks like most of you guys are running 600s. Is there a way to scale the base maps to run the larger injectors?


I read Stein's install write up start to finish. He's using an AEM wideband serially. Has anyone wired in a Innovate LC-1 via the serial connection? If so, how did you do it? The car is a '99 if it matters (I think there's a narrowband signal the ECU will default to during warmup and error conditions).

Thanks,
Pat

 

1. For a quick and dirty fix use the master fuel trim to scale the 600cc base maps that Travis sent out. 750/600 = 1.25 so set the master fuel trim to -25%. Idle may require hand tuning as usual. KEEP AN EYE ON THE WIDEBAND AND ADJUST ACCORDINGLY.
EDIT: The better way to do this would be to scale the entire base fuel table by -25%. Then let adaptive tuning work on it.

2. You just plug it in and set the Adaptronic for LC-1 input. Use the LC-1 serial plug and the serial adapter cable just like when you plug it into a PC for programming, but plug it into the corresponding serial port on the Adaptronic instead. Easy. Assuming you free-air calibrated it correctly, it either works or it doesn't.

 

Awesome, thank you.

 

Pat,
Lemme know if you want a sorta tuned map to play with. It's based on 600s but it is a good place to start if you don't want to start from scratch...

When you get back into town, I will be more than happy to GTG and share my knowledge with ya.

Cheers,
Matt

 

I remember my req.fuels being in the mid 4s. Going from 460s to 750s, I pulled 40% from my cranking PWs and it was perfect.
