Current Configuration Squirt
MegaSquirt
Self-built kit from DIY Autotune. Version 3.0 PCB. Connected via adapter harness (used a Mazda ECU connector) + extra wiring harness to the car. Originally ran the latest Extra firmware but switched to high-res to idle the 550cc injectors nicely and it seems to work fine.
Fuel Injection
Stock 205cc to drive around and test, installed 550cc FC3S injectors (x4) instead, should be adequate for ~300 RWHP @ 80% duty cycle.
Ignition
Using optical CAS for input and stock coils to drive the plugs for now. Plan to convert to Toyota COP units.
Overall, I'm floored and overjoyed that I was able to follow the directions posted at DIY Autotune on how to modify the board for ignition input/output and load up the sample maps and the car started without a hitch (aside from wiring the coils backwards and needing to block off the idle valve until I get the PWM idle sorted out).
