Hi all!
My name is Peep Päädam and i'm from Estonia. I have a modified Porsche 931 w/ 2.0 engine using K26/29 turbo. I'm planning to use VEMS Genboard v3.3 on it.
We are installing my V3.3 to my friends 944 Turbo 3.0 (yes, 3.0)
and we're planning to use cam mounted Hall trigger wheel. It's already used on 944T with Tatech EMS and has mounting for two Hall sensors (Honeywell 1GT101DC, datasheet here: http://catalog.sensing.honeywell.com/printfriendly.asp?FAM=solidstate&PN=1GT101DC) and aluminium trigger wheel that has two trigger points per sensor (180 degrees apart, because of the cam mount).
The wiring is already done and we're going wasted spark with Bosch coil-pack (everything already waiting for install).
Fuel injectors are Siemens 780cc High-Z.
Is it possible that someone would help me with setting the constants in MegaTune? Starting values would be:
- injopen = 0
- injocfuel = 1200 usec
High-Z, so no PWM-ing:
- 100% injector duty for 25.5 msec
- injector duty = 100% after that
Update regarding the injectors.
They will be Low-Z after all, so PWM-ing will be necessary.
