hey I was just wondering if anyone could tell me how to safely rescale my map to lean out my AF. My current mods are injen UICP and intake. HKS BOV recir. Catback exhaust(no muffler). I'm currently running the stage 1 OTS map and my trunk is COVERED in black soot from my exhaust. I don't currently have an AFR but I will. I'm planning on adding a test pipe soon, and was going to run the stage 2 OTS map with it. But I feel it will still be way too rich. Is there anything I can safely modify to improve this? I've also been expieriencing some counts of knock. Highest usually 7. Can anyone help with this as well?!?!

 

We have a little How-To on our Knowledge base that well help you calibrate one of our OTS maps for the Injen intake kit.

You can use this process to modify any of our OTS maps to work with the Injen Intake!

I have done this. It's still rich. Wayy rich

 

I think your next best bet would be to get someone to do an etune for you that will fix the running rich problem most likely and will add a couple ponys!! The Etune can be done with the cobb tuner as well!

 

I'm running Stock with the Stage 1 map, the highest knock count I've gotten was 6. Is this normal?

 

Have you tested the car for any boost/vacuum leaks? How do the fuel trims (both LTFT and STFT) look? Feel free to email us a datalog if you've got one (support@cobbtuning.com)!

It's definitely not uncommon to see a bit of knock count, the most important part is when that knock occurred. If you're seeing it consistently under load it's definitely worth investigating.
