Hi ya'll! I'm moving my engine build over here from the restoration forum section as I'm deep into my Megasquirt build. I saw the other post about CAS wiring and wanted to pick the brains of the folks here - I too followed the rabbit hole of searching and found that a lot of CAS information had been deleted from the forums. Would appreciate any guidance for jumpers, wiring, etc!
Engine: B20
MS: MS2/Extra 3.4.3
CAS: Yoshifab adapter with aftermarket CAS
IAT: GM sensor
CLT: Bosch sensor, calibrated
MAP: MS2 onboard sensor to intake
Spark: Wasted spark with VW coil pack, mods done on MS2 board (correctly, hopefully)
Fuel system: Stock D-jet, flow tested and pressure tested
Wideband: AEM wideband
As it currently sits on my engine run stand:
Wiring:
CAS. I'm not sure which disc to use? I believe the one in the CAS is the correct one.
I've read all the MS documentation and forums posts but I am not quite getting it. Can anyone help me answer these questions?
Wheel: Is the wheel in the CAS the best one for MS?
Wiring: I believe the wiring is as below from the documentation for the 4G63 wheel
Pullup resistors: Can anyone confirm that these are needed? Documentation says "Electrically, the two signals on these CAS are connected the same as a hall sensor and require a pair of pull-up resistors in the wiring harness." Does anyone have a 'pullup resistors for dummies' link? When it says a pair, does it mean on each of the 2 hall sensor wires?
Jumpers on board: I believe none are needed. Can anyone share their setup?
Any other advice or sh*t I'm not thinking about?
Thanks so much in advance for any advice. I'm really enjoying this process.
