Hey guys,

I've been working on my own custom tune the past week and below are the maps I've come up with. My car really seems to like the tune, as validated by the log attached. With the ECU controlled boost I'm hitting 22 psi peak, tapering to 17psi at redline.

I'm running the mods listed in my sig, along with 93 octane fuel. Unfortunately I still don't have a wideband to verify the AFR, but as you can see I only slightly leaned out the stock fuel map by adjusting the 6K+ rpm range by .5 points.

Let me know what you guys think.

Thanks.

 

are you using 93 or 91? your thread says 93 but your sig says 91. Your still super rich down low but I understand being on the safe side without a wideband.

 

ya you a litle to conservative, you gots much room for more timing and leaning out the fuel.

 

I put the log beside one of my customers tunes I recently completed...looks like you're down about 3* of timing and 20kpa, but I can't tell where your fuel is.

 

Crossing the load with the fuel map and using some experience with lean spool enabled cars your fuel is probably in the 11.0-11.2 range near redline. When you log, logging some variables like the NB voltage can give a rough idea of where its at.

Your timing definitely looks low for 93 (the 1 count scattered knock could be anything) but about right for 91. The load is about right for 17psi though. I usually see 225-230 holding it 19/20 by redline so thats ballpark for sea level.
