Re: JRockland E38 750il gen 1 supercharged

SO small update... :? I checked around the harness and modules and all that rat nest, and rode from the repair manual.. :geek: "Just adding the rusefi" won't be that easy: The automatic transmission is linked with EVERYTHING in the car... :cry: and if anything is messed with it won't work....

I actually wish I could help, I love those projects.. hmm before spending any money on the tranny, check the valve seals on the engine, they usually go bad and it is reall...

Re: JRockland E38 750il gen 1 supercharged

Hmm I know those connectors are probably really useful and look pretty but I think Ill just skip and start the harness straight from the board. I have tons of 2-3-4 pins connectors for car harness so Ill just connect each element independently for now. When it is running and functional I might make ...

the one I'm looking at is for a 5.4l v8, I can't find anything much bigger then that. I don't want a big American thing that pop out of the hood, just something for a bit of kick.

Re: M73 Automatic transmission

Will do tomorrow, a company is picking up the engine to built a custom frame so I can run and dyno it in my garage.

While getting it ready I realized 3 of my 4 knock sensors where busted, I guess bosh plastics isn't good for 25 years XD

Re: JRockland E38 750il gen 1 supercharged

Ok. Wiring is going great, now I need to know what I need to buy (version/model) so I can order the Rusefi.
Also need to know what I need to run wideband sensor as my dyno doesn't have the module.

**Also where can I buy it.

Thank!

Re: Looking for a good electrical diagram for M73

If you really want a picture :D

Still waiting for the welder to come assemble the engine frame so I can start working on it :x
And also my shop is getting painted, might delay everything by a week or two. Anyway I'm in no hurry.

Re: M73 Automatic transmission

Looking at the harness the easiest way would be to keep the original ECU's, cut off all their output to the motors and give them enough input to make them believe they are in control. This way they still control the TCM. I had been looking for people around with a similar series car but no luck. ***...

Re: Proteus v12 club

Soo yea took a look at the engine and realized the sparkplug goes right between headers.
Cable it is.

Is double spark plug a thing in cars ? I'm use to built motorcycle engine and in Harley's we would drill a second hole to get 2 spark per cylinders. never seen that in cars. just a question.
