Anyone help interpreting data logs?
 
I have very little tuning knowledge and have such have placed my faith in a couple of Ecutek tuners who are around this forum. Attached is a log from each and any interpretation by those who know about these things would be appreciated as I don't want to ruin my engine. :cheers:

Bottom one looks better.

Thanks - anything I should be worried about in either of them?

It'd be better if you could just zoom in on one wot portion.

At first glance I wouldn't want to run the top one. Too lean.

I agree - The top run looks like its quite lean meaning your engine will be running hotter than normal.

A photo with just a full throttle pull in second or third gear starting from 2000RPM up to the limit would help a lot.

^^ All true, but the bottom one has some tip in knock. It doesn't seem to be effecting the advanced multiplier though. The top one starts off with the advanced multiplier way down, it raises to .47 but doesn't go any higher. I'd be curious as to why it started off so low.

Have either of the tuners seen these logs?

First chart: Agree with the above conclusions that the 1st one is too lean and the advance multiplier is too low. The ecu is not happy with the calibration. Caveat: the multiplier is on its way up during your data logging, so potentially that 0.46 could go back closer to what it should be.

Second chart: This is better although I would ask the tuner to look into those knock corrections. They don't happen under lots of load so I am thinking it may actually be just phantom knock or tip-in knock like someone said. As for the advance multiplier being at 1.0 how long was this car driven with this particular ROM. If it has been driven for a few days and the multiplier is at 1.0 then chances are the ecu is happy with the calibration.

Thanks. Both tunes have had several revisions but I am waiting on them to come back to me about these particular logs.

Cheers. Flashed the second one straight after a run with the first one so it had only been on the car for about 20 mins when I did the run.
