no rpm
ok i've searched but i dont seemed to have found an answer.
I have a ms1 v2.2 fuel only right now on a 87 6 port turbo swap
the ms seems to be working right all the gauges are reading but no rpms (cranking or running). I have the tach wire tied to the single black wire on the leading coil w/ sheilded wire grounded in one place. i hope someone can help me pls
any and all help is greatful thx again

The megasquirt in question is the same one I had running in my fc a few years ago. Hardware wise, its fine, unless something got damaged when he wired it. But I think his problem lies in the stock ecu he is using for ignition. I talked to him earlier, and he unplugged the stock IAT and CLT senders from the stock ecu and just had them hooked up to the megasquirt.

could i have shorted out the tach part of the squirt if i hooked it up to the positive side of the leading coil ? i had a auto gauge tach hooked up to that wire and wired the squirt to it at first.
all i want to know is did i screw something up or could it be some other problem.
btw i don't have a stim and don't have the money right now. been laid off for over a month.

Buy a Stim or make one. I sympathize if you don't have any money, but you gotta' pay to play. A Stim is probably the single most useful troubleshooting device.
Have you checked the wiring on the 'Squirt to make sure it's set up to take a coil input?

Just look in the Megamanual for "Dave capacitor".
The resistor goes in series with the negative of the coil and the Megasquirts ignition input.
Can you post your MSQ?
You get RPM on the Stim, but not in the car? Is that assumption correct? If so, where do you have the ignition pickup connected?
