E82 135i N54 - Procede v5 REV3- HELP

[Dennis J]

Hi Guys,

A few Months ago i bought an BMW 135i steptronic in spacegrey with N54 and step tronic. The car was already fittet with everything from BMW, and also including M-package in and out, BMW performance exhaust and PPK.

IT was also fittet with Vishnu Procede REV3 and AFE stage 2 intake.

Now going to the dyno i found out that the stock program/ECU was tuned as well.

The dyno also use a sniffer at the exhaust tail to measure AFR. until 3000 RPM the AFR was great, but from that on the AFR went to 10:1 (lambda 0,6) all the way to redline. So insanely rich. I had my laptop with vishnu procede sw hooked up to monitor and AFR was great according to Vishnu or greater. They where around 11.5-12:1.

The DME stock tune also showed same rich measurement on the dyno. The sniffer is trust worthy on the dyno.

The power levels was nothing to be impressed about. 365bhp and 576nm of torgue. This IS NOT WHP, but CHP.

So my questions and issues are:

How badly is Vishnu affected by the flash DME tuning and why is the AFR on Vishnu not measuring correct?

I have loaded the aggresive 9/10-maps - stage 1. Can i go higher?And is there a map description anywhere? anyone tried autotune with 9/10-maps?

With the 7-29 v5 - autotuning the car would go in to limp mode using autotune - why? (correct firmware for maps was used)

Help is much appriciated.

TBH no one has ran the Procede tune in about 3 years now. They stopped selling that tune and stopped offering support for it. Your probably better off running a supported tune like Cobb or JB4.
