BTSSM log

[aaronpnz]

Hi, I was wondering if someone could look at the log from BTSSM for me. Legacy has been like stumbling or hunting at lights while waiting, revs drop etc. The AFR and FC needles swing wildly from extreme to extreme.

 

Just wondering what it might be and what I'm up for this time.

Can you do a LV for us?

Your IAM is low enough to be quite concerning too which means you've been knocking quite alot too. FKC and FLKC are worth logging to catch that.

Ditch half those parameters you're logging too. No need for double ups with different units. Can you do another log with throttle angle and MAF g/s logged aswell

 

Yea fuel correction is making some super weird swings but can be pretty sporadic even when the car is running fine as it's a live correction. Fuel learn hitting -14.1 is pretty bad as it is almost past the range the ECU can correct for and that is a long term learned figure.

 

Chances are it is a leak somewhere which shouldn't be too hard to track down as it will be quite a big one

Hi, thanks Andy_Mac, logged again on way home tonight.

 

Unable to log MAF, when selected, it freezes BTSSM up, maybe the sensor is playing up?
