Tuners Rejoice! Free Tuning For M4.4!


Recommended Posts

I honestly have zero idea what's going on or how I can use this. I do, however, understand enough to know that the smart volvo'ers can now tune their cars for free and on their own. And for that, I +1 you good sir. I'll still buy a tune from Lucky.

Hmmm... that is different. Can you get the datasheet on the chip in the far bottom right corner? It isn't on any S70/C70/V70/850 ECU's I've seen.

On another note I got SAS disabled in software, so no more need for a diode. I'm working on taking care of EVAP right now...

I explained earlier that it has the overboost function; if you go over the target load you are in overboost mode. You can only be in overboost mode for a short period of time until some sort of the load is limited to scale it back down. I'm not sure what method it uses to limit the load at the extreme, but it may be a fuel cut.

There is another factor that literally translated from German means "Drop out rate for achieving a fuel cut." I set this factor to its maximum and I set the load difference for overboost detection to its maximum and have not hit fuel cut.
