Tach Out -more detail or pictures wanted

Post by Miles965uk »

Hello
I have a V3 MS1. code 2.25. using 1 output to the dizzy. 6 cylinder engine.

I see the electrical diagram for the tach output but I have limited electronic exp- I bought the board made up.

http://megasquirt.sourceforge.net/extra/tachopin.html

I think seeing a picture of the tach out setup would be a great help if anyone has it or more info on the electrical diagram.

Thanks

Miles

I've made this mod on my PCB and just before I finish off the car I may be tempted to unbolt everything and take a couple of photos for you.

Its dead easy to construct in the proto area though...

If your tacho is from a toyota, you might find that circuit not powerful enough to drive the tacho.

See here http://www.msefi.com/viewtopic.php?t=21005 (scroll down to last post) for diagram that works for older toyotas that get engine upgrades.

Thanks,
the car is a '94 911 turbo with a straight forward tach.

ITGuy I would really greatful to have some pics of your circuit.

Just a thought is the additional hardware config all ways needed for the tach output?

I'm doing similar thing on my 930. Will post a pic once I confirmed that mine works - though I'm still having trouble starting the car :(

Do you mind posting/PM your msq? And how is yours set up? I believe you were running EDIS?
