[Fusion_MS3]

they feel pretty close to me, am i trippin?

Mods:cs sri/tip

i did two 3rd gear pulls w/ stage 0
and two 3rd gear pulls w/safe tune for cs 91

Why aren't you using Stage 1 cs sri/tip 91?

Just experimenting?

I kinda don't want to try until hpfp.

Stock MAP AFRs are indeed rich but his dip into mid 9's while they should normally stay in the low 10's.

Boost dumps too - related? I was thinking this was a Stage 0 thing.

Plug all your logs into vdyno and see how they compare.

I'd do it for you but I don't have it installed on my work comp and I don't like you enough to go through all that trouble, sorry.

I'll be your huckleberry!

I got the two that looked decent...put your weight at 180#. I think one of your logs had a shift in it, so I did not include. Someone please let me know if I did this wrong. EDIT - FIXED - CORRECTED VD - THANKS @Pseud)logik!

Comparing Safe and 0:



I see now about the afr's on stage 0 going rich...You would think opposite would happen with new intake and more air comming in, but it dives with the boost.

If you use a 1.01 correction factor and set smoothing to 3 the numbers will be more accurate, but it doesn't look like the logs were done very well in the first place.

@Fusion_MS3; log from 2500-6500 RPM in the future. But I can say right now that the safe mode map is better than stage 0. There's no harm in trying stage 1 as long as you watch your fuel pressure like a hawk for dips below 1600 at WOT.

Thanks, duly noted... I'm still getting the hang of logging. If I end up running stage 1, I'll post some logs as well.

Thanks man!

Stage 0 is the shitty stock tune. Boost and AFR drop like a stone over 5k. No reason to bother running it.

[ms3blackmica]

The key factor that seperates the "safe tune" from others is that peak boost targets are shifted farther up the RPM range taking some load off of the HPFP where it has its disadvantage.

Edit: To answer your question, you will be slower on the safe map..
