NOLRA=7 disables adaptations. It doesn't disable anything else.


NOLRA =7? Disable all ltft and stft adaptations to tune fueling perfect?
Does this apply on 551K box as well?

Glad to hear somebody is using it besides me. Nice to know the work didn't go to waste.

For what it's worth, I seem to have the best results with smoothing passes set to 4 and smoothing factor set to about 85%. There is another new version I just published.

And for the record, the correct variable to log for pulse width is tevfakge_w. You want the exact input variables for FKKVS axes to be as accurate as possible.

I used the values which you provide with your example log file on bitbucket.
There is no tevfakge_w

Can you please reupload the screenshots to your companys page?

can you make the smoothing factor visual as %number? that would be a great improvenment.

great tool btw  Grin

I was being lazy and general when I said te and being smart after that.

tevfakge and tevfa are literally the same, so either will work perfectly.

No because i did this with nolra=7 weeks ago and this was the result:
http://nefariousmotorsports.com/forum/index.php?topic=6772.msg66386#msg66386

Right now i was under the impression that fr_w will do nothing with nolra=7

But if i use fr_w to use guitars fixer nolra should be stock...

Additionally log STFT. I do not think that FKKVS will help you here... You see initial jump of fr correction right? Try to log full pulls in different gears. If the initial jump is not in the same rpm range then I think you might have air miscalculation (leak, maf, map)

When I'm back home I'll write you the variables for both LTFT and STFT. Basically (x * LTFT + STFT) * fr_w (that is without other variables such as evap, wall wetting...)

fr_w is short term fuel trim.

rka_w and fra_w are adapted trims.
