1.8 BPT MegasquirtII No Tach/CAS
Hello all, I'm a total noob to this megasquirt thing. I'm trying to feel my way through the setup in my B2600.
So here's my setup:
JDM 1.8 BPT
Miata 1.8 Intake
Aftermarket Miata 1.8 turbo manifold
OEM Coolant Temp Sensor
OEM Distributor with new cap
1.8 EGT Ignitor
1.8 EGT Ignition Coil
OEM BPT Injectors/fuel rail
MegaSquirt-II Engine Management System w/PCB3 - Assembled Unit
Ok so i'll start by stating i originally was just going to use the OEM BPT ECU. I got it wired up and it was not putting out signal to the Injectors. At the time i could spray starter fluid in the intake and it would fire and run as long as I kept spraying. My mechanic buddy suggested i pull all the oe harness and switch to a megasquirt II.
I pulled all the wiring and started fresh by going straight to sensors and leaving them with pigtails. I ran new wires from all the sensors to the MS. I started by downloading a basic 1.8 Escort GT map and loading it. Currently the Coolant temp, TPS work great. I can't seem to figure out how to get Tach/CPS to work which I assume is why there's no spark. I am only using 3 wires off the DIZZY wiring;
Yellow / Blue = G signal not connected
Pink / Black = NE Signal going to pin 24 on MSII
White / Red = +12V
Black / Lt Grn = Sensor GND
On Tuner Studio the RPMs are not there at all. I guess my questions are these, am i wired correctly to the dizzy? Next what are the correct settings on the ignition tab?
Side note, the Injectors are working great now.
