oleksiyko VladimirYesin I have made phased injection and ignition control by Invent on M102. What questions do you have?
VladimirYesin oleksiyko I am currently only preparing to install invent jetronic. So basically I need a detailed manual. @JHM announced a month ago that the detailed instructions on ignition control were going to be prepared, but it's still not there
oleksiyko For M103 you need only crankshaft sensor and ignition coil that were mentioned in this topic, I think. At least I have used ignition coil for my M102.
VladimirYesin oleksiyko what about "phased injection" - is this something different from default? How is this implemented?
oleksiyko On M102, by default, it can be simultaneous injection. In my case for phased injection I took trigger wheel and hall sensor from Audi's distributor and inserted it to distributor of M102. About phased injection and how make it on Audi you can read here: https://invent-labs.com/jetronic/docs/en/installation/audi_nf.html#distributor-preparation-for-phased-injection
oleksiyko Disassemble distributors by hammering off a trigger wheel from Audi distributor and locking ring of M102 (you'd better heat up wheel and ring). Wide the window of trigger wheel as described in instruction for Audi: https://invent-labs.com/jetronic/docs/en/installation/audi_nf.html#distributor-preparation-for-phased-injection In the housing on the outside of the distributor, make a 17x17mm window and reduce the diameter of the rotor housing to 23mm for the Hall sensor. Drill holes, cut threads and screw the Hall sensor. Place the rotor shaft on the first cylinder and hammer on trigger wheel (don't forget to hot up it) so that the beginning of the expanded window of the first cylinder overlaps the Hall sensor by half. The end result looks something like this Part no. Audi distributor that was used: 0 237 520 048
