My intake is the grimmspeed. I'm running the 93 tune while I wait for the grimmspeed one from the openflash guys. I can't get them to e-mail me back yet.

have a read of the flashing reset learning link below you can get ecu to set fuel trims in 5 minutes.

I might need some help trying to find whats going on. The AM continues to fluctuate below 1 and if I'm looking at the data correctly I'm knocking quite a bit for being on E85. My car is an auto, this mornings commute I drove it in auto mode the entire time and things looked much better than previous logs. My fuel level was around half tank during the morning drive which is Valero E85. I've been told the one I went to is low content E85. So today during lunch I went to a Racetrac that supposedly has better E85 so I filled up the tank from half. I'm hoping that wasn't a bad idea to mix it? I did some logging after filling up, I'm guessing it has to relearn every time I fill up so should I see it fluctuate like that?

The car technically drives fine, I've been trying to drive carefully but if the engine isn't happy then I certainly want to fix any issues.

It likes to knock around 2400 rpm, and although you've logged a bunch of useless stuff instead of engine load, i'm guessing it's around 0.7 g/rev as it's at light throttle.

The AT tends to knock more than MT, worse maf calibration and have higher engine loads, that last one is compounded on E85 and will cause you to have worse fuel economy than MT. Basically, it doesn't run well out of the box like it does on most MT's.

There's already a thread with example AT maps. You just need romraider and the definitions attached to the thread.

I had same experience with E85 and the knock exist between 2000-3000rpm .
these parameters increase the knock :
1. hot temperature , above 30 celsius degree
2. high load
3. higher height from see level (above 1800m)

No power mods, just an Openflash with Wayno's modified tables for AT.
The knock looks excellent to me, only slight corrections and the multiplier is pegged at 1. It looks to me like the ST Fuel trims are all over the place though. Can someone who knows what they're doing provide some feedback please? Thanks.

I would be more concerned if the STFT was not all over the place :-)

According to that article, the 15.x AFR is not acceptable. Should I take steps or are those okay where they're showing up?

Yea I had a feeling someone would mention engine load. I put it back on yesterday, some of the stuff I left in there from testing but I'll remove them. Here are logs from yesterday with engine load if you want to take a look, no pulls just regular driving.

I honestly didn't know that, good to know. I've been doing countless research and that didn't cross my mind. I hope I'm not trying to come across as a total noob about this stuff. I'm really trying to learn about this; what the data means, what I should watch out for etc. But I think I'm getting slowly a decent grasp of it.

Yep I've been looking at your thread for a while, great stuff. I've been trying to figure out how to do all of that in romraider.

Have a look at your throttle position when afr is 15 its zero, the ecu shuts off injectors on overun to save fuel this is normal

Ok giving away my secrets here

mod your IAT temp compensation tables as per below to make the retard cut in at lower temps (note mine is in Celsius you will need to convert back to that weird F scale you guys use) and the IAT activation table to make it more aggressive in the problem area.Also the activation table is scaled differently to yours
where i have 0 you use -100
50 you use -50
29.7 you use -70.3
100 you use 0

ie take a 100 off all the values you see in my IAT activation table


also mod the cold/warm/hot port/direct injection ration tables to run less port injection in problem areas ie around 2000 rpm.

I don't have my datalog to post right now. but Yesterday I received a new tune from shiv for my OFT350 SBD Kit. Ran great yesterday...afr was at 14.7 idle was perfect..now today I start it up and idle is kinda acting like a Honda with a bad iacv...and AFR is 18.1 at idle...what could of have happened? Something with the tune? I will admit as soon as I reflashed it yesterday I beat the poop out of it trying to get logs for shiv. I did datalog my ride to work so I will try and get it posted asap. Vacuum looks like its reading correctly too so I don't believe its a vacuum leak.

sounds like a hardware problem ie intake or exhaust leak, dirty maf/map sensor ect. melted wiring ect.

i would talk to shiv, turbos running lean not good
