Megasquirt talk (split from robokills project thread)

[wouter86]

to completely change the subject...

I now have a megasquirt with a V3 board lying around here with a stimulator (so if someone wants to build one, you can lend mine) and I was planning on building a jumper cable so I can plug and play it in the original 4age wiring loom.I've been reading a lot and found a site that describes how to make that jumper cable.

All the sites i saw that have write-ups on how to make a jumper cable for a 4age engine are based on engines with an AFM.Does anybody know if there are walkthroughs for MAP based 4age's?Because the plug on the AFM also contains fuel pump control and the air intake temperature sensor.

Also the writeups for AFM 4age engines mention that the ignition part of the engine has to be the VAST ignition system and not ESA.I could not find a clear answer on how te determine which system is used in the european 4age map based engines.It has something to do about 4 or 24 wheel teeth.

Did anyone ever make a jumper cable for a 4age map based engine?

Small noob question.The megasquirt has 3 connectors, a db9 connector for the connection to the pc.A db37 connetor for the wire loom in the car but there is also a db25 connector available.What is it's purpose .

I know that the MS probably won't be running the engine better than the stock ecu, but i just wanted a project i could learn something from and since there are a lot of maps available for the stock engine i thought this might be a nice project to start with.And a free programmable ecu is a nice base for tuning.
