Auto Tune

[BowlingSS]

Will there be a "how to" for using AutoTune (with and without a MAF)?

I would like to know this also.
Thanks,
Bill

AutoTune will only work in SD mode (mafless).
As Ross has stated at the start of the this topic, The best place for the Maf is in the bin. :wink:

Shouldn't this thread be a "sticky"?

Has anyone successfully run MAFLESS (SD) with a fly-by-wire throttle ??

Thank you.

Sticky??? Blacky, GMPX?

maybe I missed it somewhere, but is this remotely possible without a WB, can i work off the narrows or not?

No, you must have a wideband.

Thanks for the Sticky!

I had to go with the competition to tune my 98 a few months back due to no support yet from eflive :( was a bummer, but gotta do what ya gotta do.

I do still have my trusty efilive cable sitting in my laptop bag.

can I work this auto ve and maf magic with just efilive V7 and then export results to hand enter into my "other" tuning product????

There are a couple of key things that are needed to do the Auto Tune, from my perspective.

1) You need to be MAFless - running in Speed Density mode
2) You need to have a Wide Band O2 sensor - basically so that you can compare commanded vs. actual AFR's
3) I'm sure this is dumbed down, but basically what the Auto Tune process is doing is looking at the commanded vs. actual AFR's and calculating the difference (factor) between the two. So that, for example, in cell 4000RPM x 55kPa your factor could be 1.10, which would mean that you are over fuelling by 10% at that specific point.

In EFILive there is a MAP that calculates all these factors for you, and allows you to paste back into the tuning tool using these factors to correct your VE table. Prior to this being available within the EFILive product it was being done in Excel Spreadsheets, so ultimately you still have that option available irrespective of the tuning tool you use.

All you would need to be able to do is build two tables, one for commanded AFR's and one for actual. Then compare the two to see how far out your actual AFR's are.

Hope that makes some sense, or if I am wrong, please flame me...

Hopefully you will have your 98 support soon anyway... Paul and Ross are working hard on this as we speak!
