Running strong for 9 months

I was messing around with hooking up the simple shift light and when I went to start it, it would turn over but not start.

Ok, I had messed with the plug wires earlier, so I check those. They were fine.

So I pull a plug, gas all over the plug. Hmmm gas no spark. I guess I blew the igniter again

So I just up and order another igniter. Got it today and its doing the same thing.

So I hook up the laptop and everything looks normal in MT, Im getting readings from the CAS, MAP appears to be working (it moves) but IAT and CLT are both red and like register -44°F

Any ideas here? All I did with the shift light was use the blue/white wire from the DIY prebuilt harness to a simple PnP transistor to trigger the shift light.

Thanks in advance!

How's the board work on the Stim? Does it run into the same problem there?

ecugrad

I yanked it out last night after working in the yard all day. I was too beat to futz with it.

I'll try it out on the stim tonight and see what happens.

ecugrad

Good but bad.

CLT and IAT work fine on the stim. RPM wont budge. My stim has been bashed around pretty good though in the move to our new house. The RPM worked fine in the car.

I guess I get to hunt in the car for the problem

RPM won't work on the stim with the ignition output mods done (aka Kags board mods). If the clt and iat work on the stim, you need to check through the chassis wiring.

Will the Kags mods work with the "stim as wheel" function set?

Matt Cramer

It depends. The V2.1 and V2.2 stims will have problems unless you remove the Megasquirt's pull-up resistor, or swap R4 on the Stim for a 180 to 200 ohm, 1 watt resistor. On V2.0 and earlier Stims, the Stim for Wheel option should make the RPM work. If it's the newer Stim I wouldn't worry about the RPM at all.

WOW, I seem to find the "Perfect Storm"

The problem?

1- CLT connector and pins all corroded to crap = no CLT signal
2- IAT connector signal socket push waaaaaay to far into the plastic housing = no IAT signal

Clean everything up and adjusted the wire.

Started right up

I feel like a moron
