Title: Torque limitation based on coolant temp Post by: contrast 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: (http://www.upload.ee/image/4794052/image.jpg) I have a hard time understanding these values. Thanks Title: Re: Torque limitation based on coolant temp Post by: littco on June 24, 2015, 03:23:05 AM look for tansmn and set to -48..
Title: Re: Torque limitation based on coolant temp Post by: contrast on June 24, 2015, 07:04:01 AM 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.

Look into KFFWL_0_A and KFFWL_1_A , s4 wiki says this can alleviate rough running when warming up Title: Re: Torque limitation based on coolant temp Post by: contrast on August 04, 2015, 02:54:24 PM Will do. Thanks

Title: Re: Torque limitation based on coolant temp Post by: contrast on August 05, 2015, 08:59:09 AM 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.

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. Title: Re: Torque limitation based on coolant temp Post by: contrast on January 09, 2016, 05:44:20 PM 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.
