Funny, I had a GTX2867R on it for a while but ended up pulling it off. I was never able to totally resolve an exhaust leak at the turbine inlet and with pump gas and stock exhaust (didn't want a loud obnoxious DD), the spool was just too slow and I didn't enjoy it in DD form. The stock frame turbos on those cars were worthless, but they actually seem decent/good on this platform.

Maestro DIY Tuning Help

I am working on understanding fueling right now. I read/heard that .88 tapering to .8-.81 at redline is generally accepted?
I have been playing with these two tables along with the IAT table and have some questions. IN the tables, do i input the taper that i wish to see through the RPM range at wot? Or are these just lookup values that the ecu references and adjusts labmda based on other variables on the fly. I am used to hp tuners on another car where you set the afr you want at each range and it interpolates.
If i want my max allowed lambda to be ..88-.9 once i enter boost at wot, does the below suggest i am i on the right track? I should pick up some power by richening the mixture, correct?

Not sure how much boost you're targetting, but I think your Full load lambda at 0 seconds should at least match or be lower than your 915 mg/stk column in your DI table at 3500 rpm. Not sure how much it matters since you're in the ballpark at 0.5 sec, but I made mine match.
Interesting how your Full load is scalled 0-60 seconds. My 1.8 map was scaled 0-6.

I don't see a reason why you would target such rich AFRs below 3000 in the DI table in the last two columns. Take a look at your last two columns in DI after 5k, your values are a little messed up. You're targeting lambda .83 after you've been WOT for 3 seconds. Can't really comment on what's correct on your full load table because I don't know where you're commanding boost or timing. For me, I target .85 after 4k at 1 second and then .83 further up in the RPM after 3 seconds. Not saying it's right, it's just what I do and I think it's on the safe side.
nevermind I misunderstood what you said.
I followed the map that was already in the base file I just richened it up more thanwhat it was. So interpolation is the same just richer values on the full load maps. Boost targetis met about 3300 from a 3k mash.
I see what you are saying about the di map though, will adjust

I finally got it figured out. cleanest logs ive gotten so far and the car feels really good with no odd torque dips and pulls right up to when i let off. Hiccup in the first log was from a bump lol. 24 psi @ 91 oct with 93 in tank

Might be able to handle 92.
Looks nice and safe.
Guys what You think about this???

I'd probably dial it back 1psi all over at least. Not only are your STFT near peak on low end because it is overboosting but also lots of corrections on top end.
Ran e30 log and set slider to 30% at 25/91, looks like my blend is probably closer to e20-e25, log tool is telling me trims too rich in certain areas and to adjust e slider. stft showing -16 to -18 in some areas. fuel rail pressure dropped to 160 right after 3-4 shift. boost delta jumps out at me.
any suggestions?

E20 vs E30 should be about 5 percent difference. I'm pretty sure the O2 feedback that is logged by ED is STFT...so it really doesn't give you the full picture as to what is going on. I have found the best way to double check E content is to look at LTFT after some driving. When I run E30 I see LTFT jump to +10 and then short term fuel trims are back to normal/minimal correction. Personally I don't bother to change the slider running only E30, anything beyond that I probably would though.

Can any look it over and see how it looks? I will post more in a bit..
