Boost control Hi I've obtained an audi N75 valve and want to use it for boost control Q The primary question I have is: Can I use a extrafet/specfet for this or should I use a injector output for this? A Spec/extra fet can be used but since you are switching inductive loads fitting an flyback diode is required can be mounted either inside case or external across valve wires (diode pointing towards +vbat connection). The Boost control solenoid seems to be working now. Will try to tune it one of these days. ---- OLD / solved issues for reference by other users perhaps experiencing simmilar problems ---- |
| Thanks. Problem solved. It was a bit of a dual problem. one the tps threshold for idle was to high AND there seems to be a bit of a problem in the fuel cut implementation. The fuel cut rev is devided by about 1.6 some way. Will look further into this. |
