Re: Turbo Fuel Setup

Yes this is the way if you want to get a fixed max output voltage from the IAP sensor. It would also be possible just to put a conventional diode in series with the IAP line to the ECU and cut about 0.7 V from the signal (gives max 4.3 V out even for high boost). The disadvantage would however be the upper level is reduced more than necessary and it may not work since the low voltage limit of 0.5 V is violated. The lowest voltage with a diode in series would be 0 V and not 0.5V, which seems to be required by the ECU.

Thanks for great input though which guided me to understand the need to limit the stock IAP signal and how to do it
