got the megasquirt running today guess what the culprit was

thats right, stock bmw harness.

lol.

 

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

 

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

 

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

 

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.

 

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

 

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

 

yea wish he had them back when I was getting it done. Whatever, more ---- learned.

cant get my ------- LC1 to work, gonna drive me bat ----.

cars runs ok on my basemap, but needs a wideband and some love.
