Thoughts. Hope to not derail the topic too much.

This. The tuning process can be a little bit of a learning curve for people unfamiliar, but the better tuners will pick it up easily enough. The other issue is the speed of flashing. You can tune other platforms that offer live tuning 3 to 4 times faster than the current solutions on the market for us.

Ok, here goes. As the original post suggests, I am one who has very little tuning knowledge and have such have placed my faith in a couple of Ecutek tuners. Attached is a log from each and any interpretation by those who know about these things would be appreciated.

Ok, so just got a new tune, and while my tuner assured me its all dialed in, want to post and get everyones opionions. Biggest thing, is before i had pretty much "0" knock correction all the time. Now i am getting swings of -1/-2 or so at WOT every once in a while.. It has hit -4 once as well.

Does that seem right?

My tuner said that since im running e-85 shouldnt really be a concern.

Here are some logs...
log one shows the knock correction, second log has none, as its not all the time.

2-4th WOT

3rd WOT

Yeah thanks. I do think an FI guy might have more insight. Hard to say, as I am just starting to understand these logs. So not sure if there is a big difference between NA or FI logs.

The first log didn't seem like a 2-4 gear pull. just a normal 3rd gear wot pull. However you had some nice knock in it. it wasn't just tip in knock.. it looked like it was at -2knock for sometime and it was pulling timing.

The first -2 knock event lasted damn near 500 rpms worth of knock.

The 2nd -2 knock event last a long time. Lasted from 3500 rpms till red 7300 rpms and then stopped knocking. that seems to be a long time for one long knock event at wot.

For me i have had -2 knock but its been at crusie and at really low rpms and low throttle input. throttle tip in knock. I think the first knock event you had was that but the 2nd really bad one im not so sure.

Got a couple good 3rd gear pulls today.. went to a long stretch of road with no traffic about 45 min from home. I could only get to just below 7000 because the road starts turning

This is my first ECUTek tune.. my tuner will be reviewing my logs and sending me an updated tune. hopefully soon.

I don't understand the dip in throttle position.. I had it WOT up to 7000. Is physical throttle position different than this parameter? I see a correlation with ignition timing, but I don't know what that means.

If you look at engine load its doing the same thing. Ill look at mine tonight and see if its the same. Weird but maybe not

there's a lot more than just throttle position that goes into calculating target throttle plate angle in any given situation. a simplification is to say that requested torque is resolved from a 3-dimensional map of accelerator pedal angle and rpm, which is then used in another map to look up a target throttle plate angle. in reality it's more complex than this, with other maps involved that i don't understand. point being you can't expect a steady input to result in a steady output.

Here are some logs of my Innovate SC w-70mm pulley on e85. Other supporting mods include FIC 540cc injectors, DW65c pump, FA20club IAT relocation kit, Rev Works UEL header and SRT HB exhaust. I'm a noob when it comes to tuning but I have been trying to educate myself about what is what when looking at data logs. Tony@FA20club is tuning the car and he has NOT finished revising (He's been very busy so I'm still waiting on the next revision). In the mean time I would like someone take a look as I have some questions about what's going on in the logs. Do the short term fuel trims look way too high? Is the knock correction I'm getting tip in knock? When I'm driving normally the car feels a little sluggish. It hesitates when taking off from a stop or giving it gas at lower rpms. I know Tony will get the car dialed in but in the meantime I feel like I've been over analyzing the logs trying to understand what's going on with the car. Feedback is appreciated thanks
Here is a link to download my logs. For some reason 1 of the logs got uploaded multiple times so please ignore the duplicates.
