I thought to use partly old wires, most grounds will be new.
- Original TPS Bosch 0280120400, 5 pin connector
- do you know pinout ? measure voltage in a factory setu[
- Can it be used? most likely. datasheet link ?
- Original IAC BOSCH 0280 140501 3 pin connector
- resistance between pair of pins ?
- Original CLT Bosch 0280 130026
- most likely good. Measure resistance at known temp, and see if resistance drops as you warm it a bit
Best place to set IAT, before or after TPS? This is a tough issue, depends on a lot of factors. If you can place after TPS without major heatsoak problems, that would be nice. But often
- Note that VEMS can be configured as "auditrigger" sec. trigger setup and accept Porsche 944 Turbo stock starter gear ring+crank home trigger arrangement. A bit more work perhaps, but install will be neat and clean (i.e. no additional trigger wheel etc).
Has anybody really got VEMS workin with Porsche original trigger, wich are 130 tooth flywheel (vr sensor) and
1 reference tooth on flywheel (vr sensor)?
Porscche turbo has 132 tooth flywheel and one ref sensor 58.28 dec BTDC
A V3.3 ordered for Porsche original trigger (auditrigger) can use
- primary trigger VR (which can be either crank or cam) with sectrig disabled
- or primary trigger=VR and secondary=VR
- but primary trigger=VR and secondary=HALL requires removing a small solderblob at the bottom of the board slightly under the FETs (in good light conditions possible with just endplate removed)
A: MembersPage/MagnusKarlstrom has his 944 working on original 130teeth+crank home signal.
You have to order VEMS as secondary trigger auditrigger option.
Question: about plug and play motronic. Wonder does the shielding of vr sensors work if i use some kind of daughterboard to install VEMS to motronic connector? Any experience?
- apparently most people solders wire between the VEMS genboard (mainboard) and the motronic connector (a bit hack, but it works, and some hotmelt secures it mechanically).
