Tune and Data log Review

Unread postby Gatorsfan1979 » Thu Dec 03, 2015 7:57 pm

I would like for you to look over my tune and data log. I'm looking to improve low end power. The car runs great on top end. I changed from 3.55 gear to 3.23 and ran about an 1" taller Street ET tire and lost half a second in a 1/8th mile it was all in the 60' time no wheel spin. I was thinking that I might could tweak timing to help. The data log attached is cruising and a 2nd gear pull on the street. I don't have a recent drag strip data log and I can't really test 60' on the street blows tires off. Any help would be appreciated

Thanks.

you didnt max out the backflow clip fn037

your maf transfer is inverted

and its got two pretty good humps in there

it looks to be heavily over advanced at WOT

I wouldn't try to squeeze any more timing into if anything she would most likely pick up some power by taking some timing out of her

your fuel looks close but not dialed in too well, you have quite the fueling offset between bank 1 and bank 2

Okay I maxed out the backflow clip in fn037, not sure why maf transfer was inverted something to do with BE it appeared to invert almost everything I reloaded strategy and tune seemed to fix, I massaged the maf curve to be smoother, I disabled WOT Spark advance parameters and I am using Spark Sealevel Table, and Spark-Advance vs ACT to pull timing. I have copied your A9L2 timing table ,Spark-ECT Adder over. To be honest I have no idea what set the timing at I have read your timing write up and i'm not sure where my heads fall in on the MBT chart. I will upload head specs. As far as fueling offset between banks i'm at a loss on that one any advice on how to fix that would be greatly appreciated.

those heads should mbt somewhere around 32 degrees

with 10lbs on her you should probably back it down to 24 degrees or so, iirc you had 26-28 degrees in her, can u post a pic of a plug showing the burn across the backstrap ?

Galaxy S6... That doesn't sound good at all I would have thought that I would have noticed if it was detonating that bad. Guess that's why you pay somebody that knows what they're doing.

I would recommend pulling the wot timing down to 18 degrees for now, start off by dialing in your fuel first with the meth disabled, it would be easiest if you simplify the maf to 0.25 volt increments, if you can bypass boost for the time being dont exceed 32 degrees until you get the fuel dialed in, then toss a new plug in it onee cylinder at a time while swinging timing around and checking the plug after each pass to see exactly where shes happiest n/a, then once you find mbt n/a hook up the blower and drop the wot timing 8 degrees of so, re enable the meth and see what kinda timing she likes with boost

I wouldnt recommend beating on it too hard until you get it dialed in safely

Thanks for all the help. Going back through my tune I found that I had scaled my breakpoint wrong and it was causing the humps in my Maf curve.
