Log : Cobb Stg2+FMIC Aggr v401

bv1 · 03-31-2012, 06:40 PM

Was hoping to get some insight on the log I captured today. Mods are in my signature.

I'm getting a timing correction on cylinder#1 and throttle closures. Is this likely a bad coil pack? Boost is kinda rocky as well.

How is the timing profile? standard for this map or low?

Is it normal for the tps to close like that for stage 2? Maybe because of the boost spiking, idk.

The A/F are bouncing between 11.5-12.0, I was just logging my stage 1 v401 and was flat lining 12.2. Cylinder 1 seems to be a common problem on most cars logs, mine being one. Swapping coil pack would be where to start.

Thanks for the review. Yeah, I'm not really clear on TPS closures cause and effect wise.

I didn't look that closely at the AFR ratio. However, it seems to represent a harmonic oscillator dampening as it approaches ~12.0 not sure if this normal or not.

I'll try swapping coils and see what happens.

I'll re-post log in the Cobb thread. Should have been there anyway my bad.

Did you post your log?

I never posted my logs. I'm not a pro but I think my logs looked good enough. Car drives amazing on the V4 software.

I don't think harmonic oscillator dampening has anything to do with a/f. Mine is locked in at 12.2. Somethings are better to look at on a spreadsheet rather than a graph IMO.
