Introduction
I am planning to install VEMS on a Fiat/Lancia 5 cyl. 2l 20V engine. Since I have no previous experience with engine management the time frame for this project is pretty much unlimited.
Some data on the engine:
- 5 cylinder, 1998cc, 20V, turbocharged
- Firing order: 1-2-4-5-3
- OEM ECU is a Bosch Motronic 2.10 with a 58+2 (60-2) missing tooth trigger wheel.
- Stock injection timing sensor is a Hall effect sensor, reading off the exhaust camshaft.
- Coil-on-plug setup.
- Fiat VVT, simple variable valve timing system.
From what I can tell (which isn't alot) all sensors needed by VEMS is already there (except MAP sensor). Problem seems to be to figure out if they can be used.
- Since almost all components are made by Bosch, there shouldn't be any problem with these sensors
I have two sets of injectors, high impedance Bosch. Standard ones are rated at about 330cc/min@3 bar. The second set is rated at 384cc/min@3 bar.
Questions
- How can I tell what sort of crank trigger sensor is used. The manual only states part no. which havn't helped me alot.
- measure Ohm with DVM. Any combination of pins, in both directions. DVM Diode mode can help too.
- OEM coil-on-plug setup can most likely be used. Is there a way to find out if they are "active" or not?
- measure Ohm with DVM. Any combination of pins, in both directions. DVM Diode mode can help too.
MembersPage/EmilMalmsten/AudiS/OldPage is a 5cyl that was running on 60-2 (+ camsync, of course) earlier, before it was converted to InputTrigger/AudiTrigger.
