Procede V4 A/F Ratio reading?

Tronner · 11-08-2010, 10:38 AM

I have done some datalogging recently and noticed my WOT AFR with my Procede is 10.33:1 from 4800 rpms to redline.

Current mods are:
AMS FMIC
AR designs oil cooler
AFE intake
Borla exhaust with race pipes

Does that seem pretty rich? Is there a way to adjust that AFR? I thought I had seen much more lean AFR targets posted before? Am I not logging something correctly or something?

I think you are looking at the wrong AFR sensor. With the current software "air/dual" ratio is actually derived from the rear narrow band sensor which isn't accurate. You want to look at the front o2 wideband readings which are misappropriately labeled CAN coolant temp and CAN knock. That gets fix in the next software release.

Ah, thanks Shiv. I will try that out! One other quick question while you're around haha. I am going to be putting AR catless downpipes on my e92 XI in the next week or two. Probably running the stock exhaust. What do I do with the O2 modifier - what setting should I start with?

Reading your support site for the Procede I guess with CANclear on I shouldn't have to do anything and leave the modifier alone.

No problem. You shouldn't have to do anything to the o2 modifier. Just leave it set at 100% and let CANclear do its thing.

leave it at 100% and have CANClear ON.
You could also totally remove the 02 sensor functionality since CAnClear will just clear the codes and NO Cell will ever appear.

Unless you have old BMW progman software, from 2007.

I can run o2 modifier at 80% and be CEL free (I also leave canclear on).
