car: 08.5 MS3

I have included a couple of logs (From AP).
Running Stage1 stock vehicle map v1.03.
Stage1 for Stock Vehicles. 93 octane fuel.

I know..they are not graphed but deal with it.

I am running 93 octane fuel.

Also, what the difference between actual & equiv A/F ratio.

The car feels damn quick but kind of nervous about that lean spot when I hit boost.

Considering running the stage 1 stock vehicle map for 91 octane to see if it richens up the mixture.

Logs 2 & 3 were WOT..not sure what gear.
Log 4 is partial throttle not sure what gear.

I was running the Stage 1 stock 91 octane V1.03 for the last week and was getting huge boost spikes in the 22 psi range. Target is 17.5 psi!! I switched back to the installed stock map...

I posted this on the other forum as well. this is your data. More people will look at it if its graphed

acidbbg,

Based on this graph, what is your question? Fuel pressure, knock retard, boost, and air/fuel ratio look on target for a stock setting.

Fuel Pressure: above 1600psi, GREAT
Boost: spikes around 17psi, levels off to 15psi, OK FOR STOCK
Knock Retard: never above 1.5, GREAT
Air/Fuel Ratio: around 12~12.5, GREAT

I'm sure dread meant to say you should NOT load your car up under 3000k rpms. I think the log looks pretty good for a stock car.
