ACK!! CLT & IAT are not registering in Megatune
MSI v3.0
Kags Board Mods
KingofFleet PnP
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!

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.
