Auto Tune. Inspiration for developers http://www.youtube.com/watch?v=qwkqjotkDJQ&feature=related


General wishes

couple of WOT runs on stretched road over rpm range

step0:Run 1 record ignition angle and A/F

step1:Run 2 retard ignition 2 degrees and run again

step3: compare A/F in run 1 and 2

step4: if step1 A/F > step0(retard 2 degrees) else advance 4 degrees. ect. ect.

Found this program Virtual dyno and hope we could have the same function in Vt so we can see when we are making more power Hp/Nm

make a 2000-6000 pull and 100% tps

Convert to .csv

open csv file in excel

delete the first line “vems” to make it work

Nice functions to have in Vt:

Peek Nm and Hp

3 runs graph in the same row

Measurement on the fly


Wish for the Round

A wizard to create the wideband custom curve would be very useful, just a simple two point linear curve generator would suffice in most cases that allows you to simply set min/max lambda and corresponding min/max output voltage. It's also useful to have a test-mode where you can force the output while checking for the same result in the ECU that receives the signal. The test mode is useful for all output types, not just the custom curve. I got within 0.01 AFR acurracy from 10:1 to 20:1 AFR with an Autronic unit, if not for the test mode I would have been 0.4 AFR off at either end of the signal.

Download WButil for TechEdge WBO2 and play with it: [Unzip and run]

Here is how it's curve wizard appears with the test mode,

The blue line is the wideband units signal and the red line is generated from the wizard. The crosshair is at the test output voltage.
