Could somebody basic map for 850 R/T5 for m4.4 ?? Thanks If you pull the hose from the WGA there is no any boost imitation from the ecu any more. It should be a hardware problem, like a leaky compressor bypass valve and or some hose poppet off? Or simply a worn turbo that isn't capable of doing more boost due to cracked turbine housing or wastegate flap/valve.

If a used an old m4.3 ecu and pull out hose from actuator the turbo going up very well - about 1,3 -1,4 with the older and smaller turbo, just short time, because it wasn´t regulated.. I tested 3 different compressors..every hoses are new, differents actuators, "smoked test" of hoses and pipes...every time the same problem. The last turbo is new - 19T compressor - i really dont worry about low value.. Edited January 4, 2018 by ady123 Quote Link to comment Share on other sites More sharing options...
Beunhaas Posted January 4, 2018 Report Share Posted January 4, 2018 (edited) Ahh maybe you have a fuel cut? That would be software related yes. How did you adjust your wastegate actuator? Edited January 4, 2018 by Beunhaas Quote Link to comment Share on other sites More sharing options...

How did you adjust your wastegate actuator? Yes, of course, looks like a fuel cutting...because with every turbos and actuators was the same every time.. Wastegate actuator with basic value working as well...if i made some turns (i did it different many times) on the actuator shaft) it works good may to 0,9 bar max...more turns on shaft didnt help them for value...every time stands on 0,95 bar, if value jumps a little more, the angine missed ingnitions...power fall down Quote Link to comment Share on other sites More sharing options...

Time to get tuning and read this thread from the beginning including the Wiki. Happy tuning ;-) Quote Link to comment Share on other sites More sharing options...

Thanks. Of course it is about tuning of converted from 4.3 to 4.4 on 850 T5r, and custom software which i did...but i have some problem with boost - thats not about tune of m44? 7 hours ago, Beunhaas said: Ah why didn't you say that in the first case then, it's a safety you should be happy it's there.

Happy tuning ;-) i read this topic, maybe u didnt read my posts from the begining.. i didnt want basic value...and power, i have custom ecu and did custom soft,mate..

Beunhaas Posted January 5, 2018 Report Share Posted January 5, 2018 Sorry mate didn't get that. So what do you have on settings under: Limiters -> Overcharge Load? Quote Link to comment Share on other sites More sharing options...
Phillyc2003 Posted January 5, 2018 Report Share Posted January 5, 2018 hi all i am getting near the point to start logging/mapping but have a small question for those that have used the wideband i have. I have almost finished fitting my wideband (innovate scg-1) i am using the 4.9 lsu sensor, there is only one wire off controller for logging via ecu, will this be suffice. and does anyone have the correct calculation for it on setting it up via tunerpro rt. any help appreciated Quote Link to comment Share on other sites More sharing options...

Beunhaas Posted January 6, 2018 Report Share Posted January 6, 2018 Don't think you reach a load of 12 @ 1 bar charge press I guess? Can you see the fuel-cut happening in you logs? Quote Link to comment Share on other sites More sharing options...
