Hello all. So a tuner friend of mine owns an 850R like myself and is giving it a go with trying to tune our vehicles. We are having issues with controlling boost. We cannot get any boost to build. He's tried adjusting target load setpoint, didn't seem to make a difference. Same with adjusting TCV Duty Cycle Pilot. Looking through the M4.4 Wiki, made sure he's changing values in the 70% throttle column. Also tried disabling LDR routine to get 1:1 control with TCV duty cycle pilot, no change. We've tried the Volvo TCV's and a Mac TCV, no change. He is auto so he's using a 607 bin, I am manual swapped and it does the same with a 608 bin. We are using a 610 ECU with an ostrich chip for live tuning/datalogging. He was able to get a good base tune with a MBC on my vehicle, but obviously we want TCV control to finalize tune and have everything working smoothly. Have you guys run into this before or know the solution to this problem?
