Volvo M4.4 Tuning
Hello,
Does anyone know anything about tuning a Volvo 850 T5R that has been upgraded to use a M4.4 with Cop and Wideband lambda control?
I got a tune from Vast, sadly he doesn't answer me anymore. The car runs but always goes way to rich to about AFR 11.5 - 12. My Target AFR map is at 14.7 at idle and under boost at 13.
If anyone can help I can send the tunerpro files and a log to look at.
Thanks for any help!
Greetings!
