These are the first 3 logs that I have taken....after looking at these, I believe my car runs better than it did on the 91 map.


Can someone have a look at these and let me know if I am wrong?


1. http://www.datazap.me/u/p5yk0t1c/first-0?log=0&data=1 (IAM=1, FLKC=0, Knock corr.= 0)
2. http://www.datazap.me/u/p5yk0t1c/second-0?log=0&data=1
3. http://www.datazap.me/u/p5yk0t1c/dee...0?log=0&data=1

The only difference between the 91/93 tunes is about 1.5 degrees extra ignition timing over 6000 rpm.

see above post from @Phantobe

This is the best I can do with MAF scaling OL.

Still rich on tip-in for a second and a half and between 7200 to 7400 ignition cut.

It will go about 0.2 leaner when IAT is heat-soaked on the dyno with bonnet closed.

Just picked up my OFT the other day and flashed the Stg 1 V2.XX 93 tune. Here are two quick data logs that I was hoping you guys ( @steve99 @wparsons ) could take a peak at to make sure its all safe. I am running 94 which has an E content of up to 10%

First log was just some in town driving between a few sets of lights.
http://datazap.me/u/dthissen/log-143...4?log=0&data=1

Second log, was 3rd gear getting on to the highway. Unfortunately I caught up to some traffic so I could not go completely WOT and why you might see a longer duration at the 5000RPM range.

Sorry if I logged the wrong info, still learning this whole process.

nothing wrong their, in fact it probably does not get much better
no knock
iam 1
long term fuel fuel trims max 2%
afr looks fine

Thank you sir. That's what I thought too, but it's always good to get a 2nd opinion lol.

@steve99 here is another if you don't mind. I noticed my LTFT are a bit lower now. http://datazap.me/u/dthissen/log-143...0&data=1-2-3-6

all good, ltft will vary a bit due intake air temperature changes and fuel formulation especially changes in ethanol content, thats what its their for.

Thanks again

would someone mind taking a look at a log for me. Just switched over to corn juice for the summer and would like to make sure everything is running ok

looks ok
knock ok
running richer than commanded afr but oft tunes do that
normal for oft tune on E85

your IAM is not monitoring correctly, make sure you have updated tablet and running ofm V20 and template 7.2

I completely forgot to update after you told me about that when i posted my 93 logs. I just updated. I'll log a few WoT pulls tonight and post another log.

Thank you very much for continuing to help!!

@steve99 or anyone

Can you check these out? I know I'm getting a bit of knock I'm working on editing the timing, currently going onto rev3.

But I seem to be getting some weird jumps in AFR & ST Fuel Trims. I'm running Stg1 91 Tune, just swapped back to oem exhaust manifold. LTFT seems to be pretty stable. Open loop AFR seems to be a bit lean, I was used to seeing like low 12s now I'm seeing high 12s even low to mid 13s. Also when I'm coming to a stop @ idle I see the AFR jump down to like 13.5 then jump up to 16, seems to be acting weird I don't recall this while on stg2.

Dont worry about stft it varies with heap of factors like load throttle temp ect, long term fuel trim is the one you watch its the average of stft over a sliding time window and the difference between commanded and actual afr. yours looks ok.

When your rolling downhill or to a stop the momentum of car is used to turn engine over and the ecu shuts off fueling to save fuel so you will see afr go to high values like 20.

Looks like you still have some knock arroind 3000 to 3400 loads 0.8 to 1.1 , probavly what knocking your iam down.

and some 4800-5200 loads around 1
