First logs ; opinions?

Ok guys - as I've stated before, I've NEVER tuned a MAF car before. I've always tuned SD. This car has DSMLink v2.5, so I'm tuning it on the stock MAF (I'm going to eventually upgrade to v3 and go SD, but for now this will have to do - the wife will kill me if I drop any more $$$ on this car right now haha).

Here is a rundown of the combo:
'95 Talon TSi AWD
Evo9 springs/retainers
Kelford 272 cams
FP Cast Race Ex. Manifold
Precision SCM-6031E turbo
3" Exhaust
Spearco 216 FMIC
Crappy ghetto'd IC piping
Greddy Type RS BOV
FIC 950cc injectors
ACT 2600 Clutch, streetlight flywheel
Aeromotive AFPR
Walbro 255HP pump
1G CAS mod

I think that about does it for mods.

I'm pretty sure I have this figured out, so correct me if I'm wrong:
1) Use WBO2/AFRest/WBFactor to dial in the MAFComp sliders for open loop ; WBFactor should be as close to 0% as possible.
2) Use Fuel sliders to set desired AFRs in open loop.
3) Begin adding timing slowly after fuel is dialed in.

Am I on track with this?


I'm attaching a short WOT pull to 5k, and I'll upload a short cruise log tomorrow. Feedback is welcome.

Looking good... Only thing i would say and im unfamiliar with 2.5, but it looks like about 600-900hz mafcomps need to be increased 7% or so. Rough guestimate lol, but thats the only thing that looked askew to me anyway. 28lbs at 19psi. I have a 5858 thats new and seems to flow quite a bit more at that level. Just a comment, its of no concern but i thought the 6013 flowed more(just from the numbers being larger than 5858). Though ive never heard of one. Is it an older turbo, im curious

Yeah, the 6031 is an older turbo, a 60-1 unit. Precision always claimed it's 580hp capable, but I've never seen a compressor map on it. I'm pretty sure there's still a boost leak or two in the IC piping, which I'm not fooling with because I'm gonna replace all of it very soon. I've been adjusting the MAFcomps, but I'm still working on dialing it in (and with boost leaks, that's going to be pretty well a losing battle haha). It should come alive when I replace the IC piping. I mainly wanted to make sure I was on the right path with my understanding of how tuning with 'Link on a MAF setup was.

If you had a significant boost leak i would think you would have to do some seriious mafcomps up near 18psi and your not. If you have leaks theyre obviously small or else you would run alot richer. Your afrs are good for the most part. After the BLT, you can dial it closer to 11:1 if you like. At around 1600hz your comping only 4.7% which is not bad. That there tells me theres no gaping hole letting air out. Im doing a BLT soon too, i still havent done one(shame on me i know lol)
