Hi Guys,

I've got a Turbo AVO Stage 3.



What do you think. I don't think it's knocking much...

First tune with it and it's driving real nice.


Getting a bit of boost creep going up to 10PSI but apart from that, it's running real nice.

Fueling and timing are all over the place actually, you don t even know the real afr since it s maxed out by tune

Yeah I need to get an actual afr gauge.
Avo says the tune is trying to target 11.3 but obviously you can't tell with the stock sensor

Didn't realise the fuels and timing is all over the place.

Might need to get a dyno tune sooner then I thought

This is the 2nd tank of e85. It would have 1-2 litres of 98 fuel still mixed. Driving up a mountain.
Should I be happy,What do you think?

maf is a little off on open loop
Probably would run better fuel-wise with some more petrol mixed in and less ethanol

That increase IAT from oil cooler messing with fuel trims, but man this thing stays strong in the heat now. NO power fade with heatsoak via butt dyno. E85 log from earlier yesterday.
That knock correction you're getting at roughly 3200-3600 RPM and 0.6 load -- have you figured out what that is? I've got similar knock at the same load ranges. Looks like it happens twice on your log, once was -0.7 degrees KC and the other was -2.8 degrees KC.

On my logs, here is one large KC event that caused IAM to drop to 0.88:

https://datazap.me/u/darksunrise/202...zoom=6097-6225

I cut about 4-5 degrees of timing from the base timing there and that helped, but still occasionally see knock there:

https://datazap.me/u/darksunrise/202...4&zoom=621-923

I doubt it's false knock since it happens at a specific load and RPM range, but seems odd to me that it would knock like that on E85.

Also are you using a catted header?

I've been hunting down the cause of that knock for years, bro.. Chalk it up to "phantom knock". Although I've found that a catted front pipe vs a straight one, the catted OE pipe will always register less amount of knock correction at the .6 load area in the sub 3600rpm range. I'm not sure if you recall. That "knock" only happens half the time that I hang the load and RPM's in that load and rev range. pretty much 50/50. Half the time it does nothing. Same on petrol. I haven't hooked up knock ears to it, since I dont have much experience with them. If you're worried, maybe give that a shot and see if that help you correctly categorize whatever it is thats is triggering the sensors.

Besides the original equipment that come on the car. I've ran 3 separate catless headers. If a 17 up header falls in my lap, I will likely develop a flex fuel tune for it.



I think cams might have something to do with it. Loose exhaust components will obviously exacerbate the problem. (thats from experience)

That's really interesting that the OE catted FP results in less KC there vs. catless. Wouldn't expect that if the knock was real. Have you ever gotten KC more than -3 degrees at those loads/rpms?

The knock ears is also a good idea but I don't have experience with them unfortunately.

I've cut so much timing out of those load cells/RPMs that I'm actually running less timing there than the stage 1 gas map. Seems like it may have helped, but hard to say since like you said, the knock seems to appear randomly. I might eventually take your approach and just view it as phantom knock, but going to try one more thing first. If I find something that eliminates this annoying KC, I'll let you know.

With a 2.75" straight front pipe, I had all sorts of false knock. I'm guessing perhaps extra vibration at that load or the "harmonics" of the pipe amplifies whatever it is that is causing it to pull timing. That is my best guess, and I'm sticking with that theory until proven otherwise.



The trick is.. not look at it too much. lmao the more you try to reproduce this in logs and staring at it the more annoying it will get. You can play with the cams, fueling or timing to try to reduce (which I did as well). I ended up doing a bit of richening of the fuel map at those loads, pulled a bit of timing and called it done. I also tried adjusting the cams a bit, but after I saw I wasnt really effecting that KC, I decided not to pursue that rabbit down the rabbit hole any further. But if you figure it out, let me know. I would really appreciate it. lol

Edit: while adjusting the cams I did notice where it’s “triggered” seems to move up or down the revs by a couple hundred rpms. It stil had the same KC same amplitude just at a slightly different spot. Now if you manage to make it occur, say, only 20% of the time as opposed to half the time. I’ll call that a win.

Wayne roms e85 tune 3rd tank, 700kms 2 pulls and some driving. Before I touch any thing. I`ll wait for recommendations. cheers.

it's very good, maybe you can try with his version +2% rich
since your open loop is a bit lean (even if e85 is keeping strong, i would enrichen a bit

Rescaled my maf from my last Log and these are my 2 new logs 1xCL and 1xOL.
I think they are good but I will wait for the comments from people that have more than my limited experience.
Comments welcome!

LTFT is very poor.

You can try increasing the rpm range for CL like this.
