Perrin intake, OFH, Perrin OP, Invida Q300 CB

Thank you.
If I could get an AFR log like that with ZERO knock and only -2.34 LTFT constantly across the RPM range I would be rapt. Not sure about the -10 LTFT on over run, do you have a pop tune or similar? Trouble with changing the MAF scale is its gunna effect WOT AFR due to a change in LTFT.

Adjust your logcfg.txt to grab data for tip-in instead of tip-in-enrich. T-I-E is a constant IIRC.

The correct tip-in is zero almost all the time and only spikes down occassionally on accelerator movement.

Hello!
please tell me your impressions about the logs. It´s 2x WOT at 3rd year and a bit of gentle driving ("mix" log)

Running NA with catless header, stock intake. Modified OFT tune

https://datazap.me/u/jm22/20230911to...8?log=2&data=1


From what I understand
- AFR @6500rmp is almost 12, should I try a bit "richer"?
- AFR vs commanded AFR until 4k rpm behaves as it should?
- kock is fine. Maybe too convervative?


*I belive I have a exhaust leak on the gasket mid to final pipe. Would that influence somehow?

Hi,

It's an 86 from 2013, stock air filter and stock header.
I'm on Wayne's rom E85, lean -2.
I don't understand my IAM remains at 0.98 while my ethanol is around 80%. This is the first time that my IAM has fallen. It has always remained at 1 even with Ethanol at 65%.

Does anyone have an idea?

Here are two logs, one a wot and one normal.

https://datazap.me/u/visclo/log-1695232857?log=0&data=1

https://datazap.me/u/visclo/log-1697888228?log=0&data=1

Thanks.

Thanks.
remove some ignition timing from table Base timing B
under 2000rpm and over 7200rpm and sjould be good

tune looks good on your car i wouldn t touch anythjng else
anyway it s not a big deal 0.98 you still get basically full timing everywhere you could easily ignore specially if you are running e85 could not even be a real knock
