Flash Tuner For Plus T

[k31th]

I have been running the adjustable rate of gain fuel regulator and wideband sensor for over 6 months now...running up too ten psi with external..I now have a factory turbo and manifold too go on.. (current set up just welded flange too factory manifold..as you do)mixture control at the moment is not perfect but I keep it rich if anything..if a flash tuner can communicate with my ecu I am prepared too try it as I can make.sure mixtures are good..has to be better than what I have now especially considering timing control which I don't have..I have a spare engine which cost next too nothing..I'm very surprised I haven't needed it, even had the downpipe red hot..so will a sct tuner load the tune if I wire in a turbo map sensor..one guy reckons he already done it but really?

OK, so if the wideband sensor and wideband gauge are installed, that's relatively safe if you can keep it rich with the factory timing being retarded by the ECU when the MAP is pegged (this may or may not happen)

Depending on model, the turbo MAP sensor won't plug into the non-turbo wiring loom - wiring/plug changes may be necessary - but yes, once it's installed, your tuner can modify the ECU tables to match the relevant MAP sensor's voltage/pressure/temperature settings so that the values aren't all over the place when you plug it in.

The turbo ECU and wiring loom with the "solenoid" and "boost pressure sensor" is your ideal bet for factory boost control. Otherwise aftermarket boost control is the only option. These are difficult to tune, as the tuner will need to modify the tune then modify the electronic or manual control separately, then modify the tune again, rinse/repeat until the tune is OK/safe for a motor that is not meant to be running boost anyway.
