MegaSquirt trigger wheel sensor solution, What's your design?? Options

[draganc]

Hi guys!

I’m planning to upgrade my D-jet system on a 75 2.0 (2056) with a MegaSquirt system.

I’m still debating how to mount the trigger-wheel-sensor and would like to see some of your solutions.

Thank you for your input,
Dragan

Trust me, I really don't want to have to screw withMS, because I still have scars from it.

Here are my experiences with MS failures. I had 2 failures with wires coming loose because of solder failures at the DB 37 connectors to the Megasquirt board. Both times I was stranded. I had 1 injector driver go up in smoke on an MS1 board but that was in the garage and I hooked stuff up wrong.

And, I had the king of all failures on Jake's dyno where I could not get a tach signal for some unknown reason. When he said he has the scars from it, he's telling the truth. He got some nasty burns on his hands. He grabbed a 12 gauge wire we ran from the battery that shorted to ground on the dyno. His fast thinking and action may have saved all of us from going up as the wire ran across fuel lines. I hate to remember it, that was a really bad day. I never did look for what caused the problem, cause I never unpacked the MS I shipped back home.

That system is only as good as the builder and installer. I think the the weakness is all the soldering and the hodgepodge of used parts people use.

Since then I have run SDS. It is OK for the most part. I don't like the tuning module/ screen. I miss tuning on the PC. It is simple for sure. I had problems at altitude at Tahoe for WCR where it over compensated for elevation gain and ran lean. I had to bump the fueling by using the tuning knob. I also had starting problems that disappeared when we got back down the hill. The acceleration enrichment has been impossible to tune and I live with a bogging down at really low rpm. I'm not often down there but, on the occasional AX course it is a pain cause it forces 2 extra shifts. I would say it is a pretty good electrical carb.
