Visit Preferences to set your user name Summary of change: 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 M 2.10.4 with a 58+2 (60-2) missing tooth trigger wheel.

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. ** As simple way would be to see if you can find a transistor pack (aka an Igniter). If you have or can obtain a wiring diagram this should help answer these questions and the ones that are yet to be asked. MembersPage/EmilMalmsten/AudiS/OldPage is a 5cyl that was running on 60-2 (+ camsync, of course) earlier, before it was converted to InputTrigger/AudiTrigger.
