3.041 autotune bug?

V3 SOFTWARE
1

Hi guys
Since the 3.041 update I’m not seeing any data above 21.5 %tps and approx 5000 rpm, cells above all stay greyed out
01142946.BG3 (4.2 MB)

Looking back through the data this seems to not be working since I updated the edl-1 to the 1.17 firmware

It looks like it works ok.

If you look at Aututoune rejection reason (this channel is filled up when you perform Aututone command from menu), most of the samples are rejected by ACC enrichment correction.

4

The acc enrichment threshold for autoutne is 2%.
I will add for next build option to define this threshold. I would suggest for autotune change the acce enrichment threshold to make sure that small throttle movements will not add fuel.

I’ve just realised that the X axsi is from 0 to 20%.
It looks like a bug.

Could you post your project ?

Getting lots of rejection due to accel enrich so I’ve zeroed it out at low TPS rate, but being turbocharged and alpha-n the accel settings are proving very challenging, any tips would be welcome

If I disabled sample rejection all cells are filled so the reason is ACC enrich.

However I found 2 minor bugs ha ha. When you switch to ALphaN the X axis is from 0 to 20% by default.
The second if you change to AlphaN or Load alphaN project, the Autotune window X asis doesn’t refresh automatically, you need to close and open the window again.
