Well I went from svn from some recent date and rev785 to rev37. Copied in the xml's from the archive despite the older timestamp this afternoon, still complains about being able the same parameters, I believe they are ol/cl status, tip in throttle, and another. The first two I can definitely poll from the data tab. *shrug* I'll take a look from inside the debugger later unless you find it first.

I'm so happy that we finally have LM-1 integration. I used it yesterday and it worked great!! Thanks.

I've been testing your injector scaling. I'm on my 3rd iteration now, and the car still runs, so I guess thats a good sign.

I'm still reading up on injector tuning and would appreciate what items in the logger I can watch to gauge if your injector scaling code is honing in on the "correct" scaling and latencies. In general am I watching A/F Correction and A/F Learning to ensure they're between say +-5? Are these the long term and short term fueling items I occasionally hear about?

Will I notice bouncing around a local maxima after enough iterations are met?

Any things to help your development along that I can provide?

Well, let me first ask since I might have missed things wading through the posts in this thread.

Are you to apply only one or the other between the latency and scaling modifications? I tried both for fun, and got to the point a value of "0" for 16volts in the latencies table was offered. I denied

In any case, I just tuned my latencies by hand for now. Hit me up with any test cases I can run for you.

on the way home, today, I ran both injector and maf (.2 default).
My MAF is +/- 5%, and the injector interpolation came up with 766cc, -.19 latency change suggestion.. (didn't make the changes, though..)

I also logged LTFT and STFT. A= +6.03, B= +.78, C= -.89, D= -.19

This is the 6th iteration of using the MAF tab on 037. My LTFT started out in the +/- 12-13% range..,

With those A/F Learning A-D values, I would increase the latencies by about 2% or better yet, decrease the bottom end of your MAF tabel by about 5% and blend it to keep it smooth. Not too bad though Rick. I think you are getting closer to havign the car right!

I believe the injector latency and scaling results should only be used as a guide to get you in the ballpark of what the final values will be. As with everything else when tuning your car you need to apply some thought before blindly applying the suggested values.

Looks like you're heading in the right direction.

Hellzyeah! Thanks goes out to you for this.

The injector tab, I'm still a little iffy on.. Currently my injector scalar is 799.94 (800), and my latencies are:

Jeremy - You've got email!

Like I said above, the injector tab results are a guide only. If you are happy with your current settings, don't change them.

Yup, hence my ignoring the suggestions. I didn't look how you pulled table data from the ROM, but maybe you could add logic to detect when a minimum/maximum limit has been surpassed. Or not, I know how when I write software for selfish reasons, I generally stop when things work good enough *cough* utec logging thread issues *cough* meh

hey kascade , thanks so much for the new revision and all your hard work. i tried using the maf tool and the injector tool and for some reason it will not record any data. i then tried using rev785 with just the maf tool and the maf tool worked perfect there for me. any ideas?


Thanks

Make sure the temp ranges in either tool are correct. You'll have to see if you're logging in F or god forbid, C.

Thanks Tgui
