ECMlink Preliminary Log

[GST with PSI]

I've been breaking in my new motor on stock 450s and about 12psi. I hit almost 4k miles on the motor this week, so I'm beginning the next stage of my build. Slightly larger injectors and a tune are next up on the to-do list.

I swapped in my set of Evo 560s, and bumped up the boost to about 17psi. I didn't change the tune too much, but I did modify the fuel and timing maps a bit to combat a some knock I was seeing. I wanted to start tweaking fuel, the higher range of the MAF, and up the boost a bit more, but I'm waiting on my LC-1 to come in the mail later this week before starting to do any real tuning.

Anyways, the tune definitely needs some work still, but here's a 3rd gear pull. This is on 93 pump gas, and it was about 65°F outside. There's still a bit of knock, but I'm confident I can tune it out once I have a WB to work from. Comments and feedback are welcome. Thanks.

What MAF are you using? 30+% correction down at idle is a lot. You might need to change your global size to reduce that to something more reasonable.

I wouldn't keep doing pulls with that much knock. Or just take and lower your sliders 4* from 4000 RPM on up to help combat that until you can tune it out elsewhere.

Everything else looks ok. You might run out of injector once you up the boost.

Hey, Brian, thanks very much for the reply. I'm running a stock 1G/GVR4 MAF. I bumped up the MAF comp until I could get AirflowPerRev to and STFT in check. I used the MAFComp Adjust for the most part. I have a 2G MAF that's going in the car, so at that point, I'll need to start over with the MAFComp. I'll try and post up an idle log so you can take a look. I could very well be doing something wrong.

As far as the knock goes, I just did 2 pulls. I was going to add a little fuel, and pull a bit of timing from the cells that needed it. I got my WB in the mail today, so I should be able to make some real adjustments as soon as I can get it installed.
