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
Yesterday we installed VEMS on the 951 3.0 and the installation process was painless. Calibrated things (TPS, battery etc) and got spark with Bosch 2+2 coil-pack.
It started barely with 3 (or two?) cylinders and died after second or two, again after trying.
Of course, injector settings are way off and I quite haven't understood what reading should I get when calibrating MAP (engine off)?
And I'd like to be sure that I connected the coil-pack right. I used ign channels 0 and 1 (EC36 pins 33 & 35) but does that matter to what coil-pack terminals I should connect them (besides power supply of course, doh)?
