Msd 6btm

[DAT240Z]

I have a 240z with a 77-280z engine (N42/ N42), 83 turbo distributor and T3 turbo out of a 83 280zx,with megasqurit. I have been having a lot of problems with the spark side of megasquirt, it has not been reliable. The car have spark for a while then no spark, dies 50 miles away from home when I'm driving and have to have it towe home. I bought the MSD 6BTM box to control the spark and use megasquirt for fuel only.What I need to know is how do I install the MSD box with the turbo distributor for megasquirt to get injestor pulse.

I have read the 6BTM would work with 77-78 DISSY, as well and would be an eaiser install. Have anyone used one of these boxes on their turbo car and is willing to help.

Thanks

I use it, but you need to disable the BTM part of the MSD (the boost retard knob), just by unplugging it.

 

You can use megasquirt to control spark/timing.

 

Here's the wiring diagram for you to hook up MSD w/ MS...

280zforce, I'm confused, are you saying that if I don't install the control knob for the 6BTM, I can use my turbo dissy. If so how do I control timming, as I'm using the megasquirt for fuel only.

[Guest 280ZForce]

Yes, you can use the turbo dizzy if you disable the btm knob. You can download a version of MSnS then you can control spark/timing settings.

I dont think I mention this in my first post but my ECU has the coil driver but is not reliable thats whyI got the 6BTM. The megasquirt box have MS&SE install now,on Megasquirt site it said to turn off all the spark out puts and the unit will be fuel only. Is this how your is set up?

Thanks
