	Torque limitation based on coolant temp « on: June 22, 2015, 02:07:12 AM »

Hi

I have ME7 Volvo and it drives allright when WOT and hot. Except on cold mornings and when engine is not up to temp it surges/hesitates just a little.
I tried finding something in the FR and closest thing appears to be KFDMINS (MDZUL). I havent looked for this map in my file yet (not 100% sure its even used), but in TT ols file it looks like this:

I have a hard time understanding these values.

Thanks

I have tried disabling level 1 interventions by setting two scalars to -48 and KFMIZUOF to FF. It doesnt help for some reason. And the car feels even less smooth.

Contrast ,

Look into KFFWL_0_A and KFFWL_1_A , s4 wiki says this can alleviate rough running when warming up

Log don't guess. Don't randomly change map values, and especially don't just disable torque intervention.

Volvo logging isn't as easy. I'm a complete noob in IDA and i've worked hard to find things.
I could possibly find out RAM variables, but I wouldn't know which ones are needed.
And my logging solution doesnt output a csv file either.

It's easy, been there and conquered it once with my opensourcechipkit and another one with Factory tool, wasn't difficult but time consuming, reading the rom was a complete $%$%$%. Take it ur using DHA or ViDA not really meant for tuning.

I solved it long time ago. Forgot about the thread. I was a fuel pressure sensor giving wrong values. Actual rail pressure was way off.
