good to know, maybe i'll skip the homemade pnp harness

Re: MEGASQUIRT 2 v3 Need help firing up my bimmer
 

GOOD MOVE!!

OEM looms from all makes and models always ---- up ms installs.

the grounding schemes are NOT compatible.

the headaches this causes... are endless.

glad you found it. may this thread be a lesson to others.

I just learned something ;)

Re: MEGASQUIRT 2 v3 Need help firing up my bimmer
 

So should one build a dedicated harness from megasquirt to all the components thereby bypassing the oem one completely???

Re: MEGASQUIRT 2 v3 Need help firing up my bimmer
 

If you can, that would make ---- even easier. I just did it so that when I finish, I pop the hood and all people see is the stock ECU box plugged into the harness. Something goes wrong, I pull it, pop in the factory ECU and I'm on the road again. Convenience ftw.

Need to get my ------- LC1 working right, I've wired up these things in three cars and this one has been the most retarded. Refuses to calibrate, hope i didnt get a DOA sensor.

Re: MEGASQUIRT 2 v3 Need help firing up my bimmer
 

Yeah, but you can still ---- that up too. Grounding and power are VERY important :-)

Re: MEGASQUIRT 2 v3 Need help firing up my bimmer
 

i might still get one of those adapter boards that guy on bimmerforums is having made, if i understand right, i still need to gut a stock ecu for the connector but then its just solder the connector to the adapter board and plug MS in
