M140i engine control unit tuning

Post by DutchM140i » Tue Feb 20, 2018 4:40 pm

After reading a lot on this forum without posting I wanted to share the results of my tuning.

I had my M140i tuned at a Dutch BMW specialist, Mosselman Turbos, currently they only have an engine control unit for the B58.
They put a lot of effort into adjusting the unit with the car on the Dyno, it spent at least 2 hours on runs to perfect the settings.

I am happy with the results;
Stock torque 549 CEngTq and HP CEngHp 359.3
With control box torque 585 CEngTq and HP CEngHp 395.8

While running on 95 octane fuel.

Dutch

Not bad gains for 95RON but what were they adjusting for 2hrs on a dyno ??

Any datalogs to share to see what they achieved ?

I assume it’s Mosselman itronic - as per Mstyle’s post

The guys where initially not happy with the results, they remapped the turbo pressure until the temp got too high and then down again. No data logs just some print outs from the runs.

Looking at Mosselman too (they are a 10 minute drive away).

One of the best BMW tuners in Holland but also one of the most expensive. Not sure yet about tuning, still got warranty till the end of 2020, don't wanna waste that really...

But nice gains! You should try Firezone 102 and run again, see what gains that brings!
