First log of the spring, need some advice..

[DSM_23]

Alright, I havent done any tuning since the summer and decided to do a log today. I have my boost at 20 psi all mods are listed in my profile, for some reason the logs look VERY lean up top, keep in mind the ECU is stage III chipped so keep that in mind when looking at the MAS readings they're X2. I was only running 93 octane during the log as well... I have the afc adding as much as +13-16 from 5400 and up, and my IDC's are almost pegged at 100%. So do I need to ease down on the timing to ease the fuel demand or what? Thanks in advance!

dude, you know you cant tune, get willy to help you

 

[DSM_23]

well to update the situation I believe I might have found out a good chunk of the problem, after inspecting my manifold 2 of the bolts to the turbo were very loose which created a huge exhaust leak registering a lean condition. I'll repost a new log soon to see how it looks.

 

[spyderturbo007]

I would also look at adjusting your TPS properly, as it seems your highest reported reading was around 92%.

Can you give us the settings for your chip, such as max timing, injector compensation settings, target AFR, etc?

 

[DSM_23]

Yea I'll check out that TPS, and the injectors are 680's and compensated for that, max timing is 16 degrees, target AFR is 11:1, im currently trying to get my turbo housing rethreaded so I can put the manifold back on, the threads got wacked up upon taking them out, so I cant post a revised log till then.
