Megajolt Rev/tacho
Turbo Mini Forums

Im currently sorting my loom out for MJ, but have just realised the pin for the tacho is missing. Ive read this thread



But im still a bit unsure if you can just drill the blank pin and connect it direct or if you have to connect diodes aswell?

What is the 'Tacho out' for on the molex connector? will that give an output for the tacho instead?

Cheers

Just drill it out and connect it directly to the tacho. However, it does not work on all rev counters, but without trying you won't know.

If it does not work then you have to go down the diode route.

i was wondering weather somone has tried using a classic smiths revcounter with megajolt, and could say if it worked or not?
thought it would be good to know before buying one!?

if the rev counter is fine with a square 12V wave it will be fine with the EDIS signal. I dont know how the signal from the megajolt box behave, but it is probably not more voltage at least...

My smiths one didnt work with megajolt. The diode thing doesnt look too hard though.

Im planning on a small screen now with the new megajolt software with the dials

if it helps , the mega jolt output for tach ,works on my mini tach !

Yes, the standars rev counter from the three dial dash works a treat.

A pall of mine had a few problems getting his working and ended up converting his to 2 cylinders and driving it off just one of the coils. There are plenty of ways to get things working.

Anyone used a Tim gague with MJ, just for my reference?

ive tried and failed

Bugger thats what ive got!!!

I think it can run 2 4 or 6 cylinder though so I should be able to tap off the coil and set it to two cylinders, fingers croosed!
