COBB Datalog Review DATAZAP

n55 | FBO | 93 Octane

The aggressive maps (stage 2 and 1+) seem to not make my engine happy. Had lots of throttle closures and a few boost spikes so I've been running 2 and 2+ sport maps on 93 fuel. Car has recently cleaned intake valves and fresh plugs.

Last night I put my bms intake back on for shits and giggles. Logged stage 2 sport and still had throttle closures + boost spikes.

This afternoon I logged (see DATAZAP below) stage 2+ sport, 4th gear pull from 2500 to 6000 rpm (im in mexico so yes thats 125 mph) and the car felt great! Looks like no throttle closures and fairly steady boost which makes me feel good about the direction Im going.

AFR seems decent and only timing correction was cyl 6 to -3.56, but im ignorant on the details of AFR and what amount of timing pull is dangerous!

Seems odd the car appears happier on stage 2+ sport than on Stage 2 sport?

COBB or anyone else care to give an opinion of how happy the engine is at stage 2+ sport?

How does the boost curve look?

AFR?

Thanks in advance fellas!

I have been having boost spikes on the new v200 maps. never had them before.

I am running stage 1+ aggressive. wondered if it might be the colder temperatures. this has been happening in recent temps of 28-38 degrees F. only happens on long WOT pulls in third gear.
