Trying to get some expert opinion, how does this look?

Thanks to everyone keeping this thread going, I try when I can, but I certainly am no expert.

Looks like your LPFP is starting to $hit the bed...I'd look into upgrading, or at least refreshing, that soon.

Yep, that's about a e25 blend and I noticed my lpfp couldn't quite handle that

Everything else look OK?

Good log!
Boost rides target well. No corrections. good fuel trims etc.

For the not so good part, as already mentioned, lpfp is going low. I look at the log and notice the rich afr beyond 5k rpm (in some cases that may be necessary) I prefer afrs approaching low 12s or slightly lower. Leaning it some should alleviate the lpfp and be fine. Granted not straight forward on an ots map.

I'm running Stg 2+ 95 oct in CA (E85/91 mix) and my logs look pretty clean and the car feels great. However, my post-shift timing corrections are a little alarming. I've done some research and I know these cars are notorious for it, but still, I don't know if i should be on it hard because the corrections are recovering super slow and reach almost 9 degrees on cyl 1. I'm hoping it's just from the high IATs from a long pull (which I only do while logging).

Auto log separated spool from the rest of the run for some reason, but I'm not concerned with that anyhow.

Thoughts?

Your tune looks fine and somewhat similar to mine. I also have custom Wedge E60 tune. HPFP is only at 1000 psi for a very very very short time. Doesn't impact trims or AFR so it's not an issue. Corrections are random and correction on one or two cylinder is nothing to concern about. You have none. Your STFT also is acceptable around +/-10.

Have done:

I am running a 93 oct map with 98oct in the tank.

I am getting timing corrections everywhere, but my main issue at the moment seems to be the afr going very rich, going into fuel mode 6 higher in the revs.

Before adaption reset

After adaption reset fuel/air and lambda

Bump for a look

That is standard ots map? Ask MHD to look in to it. Yes very rich, Cant tell, may be o2 sensors? Did you code the new injectors and all that bs?

Unfortunately I have nothing to offer other than my own log of the OTS E60 map:
http://datazap.me/u/fcobra94/log-147...-17&zoom=38-88

This was the first pull after resetting adaptations ~30 miles prior, so I'm assuming it will adjust a bit with more time.

I'm mainly interested in what AFRs should look like on these E60 maps since I haven't really seen a clean log yet to compare it to.

[CoffeeBean]

I just tried the E25 map and it pulled great, no misfires that I could tell. Still stock intercooler and fuel system. I see some issues in the logs and want to make sure others agree with me. This was just a test to see where I'm at, no intentions to do pulls like this consistently right now.

I got some aggressive timing corrections in cyls 2 and 4, and IAT went from 93 to 153 topping out 3rd gear and into 4th which I know is way too high. LPFP dropped to 43 psi at one point too, and stayed in the mid to upper 40's most of the time. AFR stayed pretty much in the 12s though which I think is ok? What are your thoughts, and do you see any other issues?

http://datazap.me/u/rossburns/log-14...-21&zoom=23-95

EDIT: I see my STFT is dropping into the -20s in bank1 and -teens in bank2. Isn't that too much fuel being pulled out, and what could cause that?

Yeah stage 1+ 93 oct map.
New injectors in bank1 only and were coded.
MHD please have a look

try flashing the
ACN91
CAD94
map from MHD see if that clears up the timing.

Thanks mate,
Am more concerned with the very rich afrs atm

I'm no expert but it looks normal. Have you measured the E60 content in your fuel tank?

Pretty sure Lambda banks are for gasoline. They increase the fuel scalar tables to adjust for e60. Seems fine,can go down a tad bit. Not sure whats up w the timing between 3k and 4k.

Yup, I check it at every fill up; it's E60 on the nose. I "played it safe" by starting with E70, then moved to E65, now down to E60; HPFP seems happier now and still no timing corrections, so no extra octane past true E60 is needed to run the OTS E60 map in my case.

True, yeah, I've researched the lambda/fuel scalar topic and it seems pretty straight forward. Even after the scalar adjustment, I'm still not sure what AFR the map targets to have something to benchmark my values against for any given RPM range though.

I think Cobb OTS maps have Bank1/Bank2 AFR *target* values as a datapoint as well so that you can actually compare target/actual on a graph within a log, which I think is awesome. I guess that could be added to MHD too, which would be great given that you could monitor AFR target vs actual; just like you can with boost and load, etc. currently. MHD Tuning: thoughts on adding this to a future revision?

Thanks for your note about timing as well; given that I always seem to forget, traction control was left on so that may have contributed. Or it could be still adapting..?? Either way, I'll keep an eye on it.

Thanks!!

Wow. Those are some bad timing pulls. Are you sure you're mixed at a true e25? Also, across multiple logs, are the same cylinders pulling timing?

That's a good question, and one I thought of afterwards. I had just mixed the fuel 2-3 miles before I did it so that may not be enough. I was literally on fumes (no mileage left on the dash) and put in 3 gal of E85 with 8 gal of 93(E10), so it should have been about an E30 mix.

Just looked at old logs and there's no pattern of pulling timing on those cyls. Some there was none pulled at all, and very little on the ones that did.

I haven't done a true pull since, but it does feel quite a bit faster now than it did then...

[YoungBlood]

E85 is only E70ish around here. I mix 50/50 and it comes out to e40 or a hair under usually fwiw.

At least you get E85, they are phasing it out where I'm from.

New log I took this morning after a handful of WOT runs over the last couple days (traction control was half off this time):
http://www.datazap.me/u/fcobra94/log...28&zoom=91-122

AFRs go all whack-a-doo from 2900-3250 RPM, each bank being off by a full point; this seems to be the result of STFT1 flatlining for that period of time.

WedgePerformance: could this be an Open loop/Closed loop thing?

Not really sure what else it could be since everything is brand new (HPFP, LPFP, LPFP sensor, injectors, primary O2 sensors, etc.).

I also reset all three fuel adaptations 3 days ago when I saw this same issue creep up then; I thought it was a fluke given that I just so happened to change Ethanol content from E65 to E60, but apparently not.

Did you replace the HP Rail sensor?
