Your advance multiplier is not pegged at 1.0 ... it is responding to the knock. In the snapshot you provided it starts off low and slowly climbs up. What is interesting is it is climbing up even though there is knock events....

Yeah, in that snapshot your right it climbs. in others it has sat right at 1. It seems to change slightly.

I will setup a camera to record, hard to watch that while im driving...i will also pull the logs from the aem failsafe and see what it says.

Yeah, either pull he log of the Failsafe, or set the digital readout to the middle digital display so its easier for you to see exactly what numbers you are seeing.

For some reason in the snapshot it climbs, but looking at the raw data in the CSV from your first post, it seems to be 1 for the whole log.

Ok, so probably should clarify, the snapshot is from a log i just happened to have open and was from today. I was simply using that image to point out the multiplier setting, as i didnt have it in the original snapshot.Its not a graph of the specific logs. I changed it back, so now its referencing the right one.

Sorry, bout that, hard enough to ask for help, but probably shouldnt be confusing everyone like that.

Ok, so here is the last update. I have sent him new logs....from today. They show a wide range of knock, -1 to -5.. He is going to look them over and get back to me with his thoughts.

LOGS

When speaking to him about it on the phone, this was his explanation of knock.

"-1 or -2 on initial wot start or throttle off is not really a concern at any time. This is also the case with general cruising. -3,-4,-5 etc..knock is not really a concern unless its all the time. If it happens here and there, no worries, all the time, then yes there is an issue. So for example out of every 20 pulls i get a -5, not really a concern."

To be honest and fair....I DO NOT get knock all the time. But i do get it alot. Basically 4th and 5th gear WOT I seem to be getting -4/-5 or so like 1 out of 5 times maybe?

He has offered to start completely over and retune the car starting from scratch, for free. The problem is, he does not have any time until around the middle to late November.....so that means i am about 3-4 weeks out.

Realistically, its starting to rain/snow soon, so might not even drive the car that much, but on the flip side, i really want to on the nice days, and was really hoping to have this good for the track.

So i have 2 options.

1. Ask for my money back, maybe just partial refund? or full? not really sure how this is viewed, as he has spent time, and offered to fix, but just not confident he can. So his argument could always be that he will fix for free.
2. call it a loss and move on to a new remote tuner.

Is it even correct to ask for a refund? While he did spend time working on the car, he has yet to get it right. I feel like a nice compromise is a partial refund.

Really appreciate everyones input.

Thoughts.

Try to get at least a partial refund
But u should get NO KNOCK at all

Well -1 can be a phantom knock but -5 dayum

If you were running straight gasoline, I'd say he's right. All gasoline engines are going to knock once in a while. It shouldn't be repeatable, but it's going to happen from time to time.

Here's the thing though. E85 is so damn knock resistant that if you're getting ANY KNOCK AT ALL, it's a problem. You can destroy an engine from extreme cylinder pressures without any measurable knock on E85.

You can keep adding timing right past MBT, start losing power and destroying rod bearings with zero knock, all because E85 just doesn't like to knock. So if you're running E85 and you're getting knock, even a little bit here and there, something is wrong. Any "tuner" that's worth a shit knows all of this.

Man I think you should move on. Ask for a partial refund, if he doesnt give it just move on. That response from him is completely unacceptable. I agree with Sellout but only saying from time to time and very rare you get a -1 or maybe a -2. Then on top of that you are running the king of knock resistant gas...

But to say -5 at cruise sometimes is "ok".. It is NOT. It is not as bad as it being WOT at 7K, but it is still BAD. It will STILL kill your engine in the long run.

How far is FBM? Make it a mini vacation? What about Bob @ Drift Office. Remember all the money you have put on the car is worthless unless you have a good safe tune.

I was actually looking on maps and plotting routes to different shops to see if any were worth driving to...as you said, mini vacation. I am in Denver, CO, so trying to find a shop within 12hrs would be ideal.

FBM would be about a 12hr drive.
Delicious tuning would be about 16hr. Of course if i go to delicious, i can stop in Vegas on the way, split the trip and gamble a bit!

Might consider that. Or a remote tune is still an option.
For remote tune i am considering @FA20club or @jrtuned or @CircuitMotorsports, if they will do a turbo e-tune. I have spoken to two of these via email briefly. Circuit hassom eof my logs and offereed to look at them and get me feedback, so they might be able to help. Waiting to hear from them. I just want to make sure if i go the remote route they have a clear understanding of what i want from my tune, and that i will get good followup support if needed.

Current tuner

He just emailed me back and looked through my last logs...."Ease up on the WOT for now and I will revise the map. The exhaust cam was the odd hesitation. I will adjust timing and fuel to eliminate your knock. It may still not be real."

So he might have a revised map tomorrow. His thoughts are that the knock might be "phantom knock due to the knock detection being tuned for stock engine, but i have an aftermarket turbo".....his words.

-1 phantom knock is understandable, anything over -2 isn't imho

If I were you and had time time, I would drive to FBM or delicious.
consider Bob @Drift-Office , he's the master tuner for AVO for real....

If none of the drive up options works out, remote tune @FA20Club.com

Just my personal educated opinion.
