Stock, A/C definitely sucks away power.

This was with AC on, its pretty hot lately but the difference isn't really that bad with it off or on

The timing map is in various spots makes one wonder. The IAM being super low is a result of the knock sensor feedback -- although it may not mean much as you can tune the timing maps to shift very little if none at all due to the IAM.
You're also seeing stoich AFR's while making boost, and you really should be seeing some enrichment when boost comes in -- the leaner AFR in boost will cause cylinder temps to shoot up which can cause some detonation.

Lol just when I thought it wasn't really a tune situation. Not sure why things were setup this way but its clear its tune related. I'm using 93 oct and usually get it from the same station. This is a remote tune, I wish I could have done a dyno tune. I don't really have many options down here, any advise would be greatly appreciated. I'm on ecutek at the moment.

Enrichment on throttle as well as boost should be there as mentioned.

I will not be loading your car at all with IAM that low, putt around and make sure you have fuel side sorted by getting better fuel to eliminate it from the equation. If it's still happening, you need to get your tuner to do something.

That's the thing, I was noticing the IAM going a little crazy and that fluctuation is what I probably felt and attribute it to the heat. I wanted to go full time closed loop and that's the reason we started calibrate the WB to read on ecutek custom map O, my tuner was working on it but we never got back to it. Some say its not good in case the wideband fails but then again I think a simple(maybe not so simple) failsafe to prevent from a bad reading or too lean of a condition would be enough. The stock 02 could also go bad just as likely as the wideband in my opinion.



I sent my tuner these same logs and hopefully he's able to pick up what most of you guys are saying. I'd like to give him a chance as I never revised my tune after changing to my GTX28 from a smaller precision. Not really sure how much that could be at fault but im hoping its the case.

I really appreciate your help and feedback if you'd like me to log any parameters and events please let me know. I really just want this thing to drive normal but mostly safe. I'm surprised how the car feels so good at times, like I had mentioned this is probably when all is nice cool which points back to my ignorant assumption it was all a "heat" thing.

Tagging Mike to see if he could shed some light on the subject @moto-mike
