First off, let me preface this by saying I am new to tuning. I purchased a Neptune demon board and software license from my buddies at Wicked Innovation to change over from my crappy crome chip.

car is a basically stock a6/y8 mini-me. skunk2 IM, dc header + exhaust. stock internals.

I think I've pretty much got my fuel maps straightened out but would like some feedback. I started by setting some target afr's. did a couple part throttle 3rd gear runs and WOT runs to touch on the different parts of the map, all the while continuing to smooth it out.


the % difference is really easy and intuitive to use! I wonder if neptune has any other neat tricks up it's sleeve haha.

I recently visited VCU (2 hours from my house) to check out the physics and engineering department for school and tried to do some tuning on the way down. On the highway I managed to lean it out to ~15.5afr's between 3-3.5k rpms and 299-414mBars. Everywhere else I'm mid to low 13's.

Pretty much, I'm posting to find out how far I can take it, both afr-wise and map-wise. Can I continue to lean it out over the next column? (528mBar?) I remember overhearing a conversation at a meet a few years ago about leaning it out around cruising 'till it starts backfiring, then adding some timing for the best mpg? <--this could be a load of **** for all i know...

also, can anyone tell me how to expand the scalars out for boost? I have a little greddy kit I'm getting ready to put on and would like to finish up this basemap before just throwing it on.


thanks in advance

What are your timing values in the low load columns? if your running 93/91 octane, then you can run up around 40-42* and get a bit better MPG

Most stock honda engines can cruise around 16:1 without having misfire probems. You might want to start keeping an eye on EGT's if youre going to be running that lean though.

yea right around cruising is 40-42. i haven't touched the timing map since i don't have access to a dyno. Should I invest in an EGT sensor? I was just planning on using the .5* retard per lbs of boost (compounded) and stick with that when I put the turbo on.
