Note the warning posted on Volvospeed - don't try this on your ECU, buy a spare! Good advise...

i have a 850r ecu in the car now and my original turbo ecu on the shelf
are the bin files available for both ecu`s to test that things are working id like to flash the stock t5 ecu to the r file just to confirm things are working correctly

the two ecus should be the same mechanically, its just the boost curve programmed into the R is a bit more aggressive. Please post up how flashing the stock ECU goes. I'd be willing to bet somebody has posted files for even more aggressive set ups like you'd get with an after market flash from TME and others.
