DP with stock DP map

Post by Sakkie »

HI all,

Im new to versatuner, quick question though, I have a highflow downpipe installed on my car, there are no OTS maps available on my VT that shows map for high flow dp. The only OTS maps available are for stock dp. Can i load a medium tune file for stock dp on my car with the cat-less high-flow dp?

Yes, there are OTS maps for a high flowing downpipe. At least two IIRC...

i have VT for my gen2 and there are no ots maps in the application for anything but cars with a standard downpipe. Am I looking in the wrong place?

Indeed, for gen2 you don't have any OTS tune for high flow exhaust.
This is from a tune I used for a friend of mine who has an UR catted DP and and UR catted TP. I hope it helps.

I hope you have fuel pump internals as well. If you don't you'd better get them before you start trying various calibrations.

You're offtopic but no, you need at least a 8" wide rim for a 235mm tire of that height (40% out of 235mm).
