This means the signal from the standard ECU to the solenoid booster valve is exactly the same as the signal from the modded one. Again totally illogical. In first and second the solenoid booster dumps the power early as it should and then closes, increasing turbo boost, as you go up the gears to 5th. Given that the engine with the mod is a few degrees advanced and the fuel is re-mapped, the increase in acceleration is felt with the modded ECU. My problem is that I know the modded ECU should hold back the wastegate actuator until the gauge reaches the yellow/red zone. Assuming the turbo works as per, which it does, Apart from the solenoid booster valve, is there any other electrical unit which could be interfering with the system. It can't be the dump valve that is new and is probably set at about 1 bar. The engine is only receiving standard boost, so the dump valve shouldn't be the problem.??????????????????????????? I am hoping the solenoid valve is at fault but looking at it logically, on standard ECU the system works ok. If, as he says it does, the modded ECU is ok, then why isn't the Robou holding the booster valve closed.
My biggest problem with all this is that the mod has no effect on the boost at all.
Is there anyone in England who can help me sort this out. I will pay for your expertise and any parts you use. Otherwise this is a white elephant???
