Megasquirt talk (split from robokills project thread)

That expensive sensor is the WBO2 that NoHachi was talking about. Wideband lambda...
If we can get the tuning right you'll probably get it to run better then with a stock ECU. Especially the blended Alpha-N/Speed-density function could come in handy to get it to idle smoother (engine runs on TPS sensor data instead of MAP sensor which doesnt get a clean signal with bigger cams). But those cams arent very extreme so I dont expect much problems with at idle.
I expect the ignition part to be the most difficult to install. Running fuel is kinda plug-and-play since all the sensors are allready there. Ignition requires a bit more thinking. But the advantage is that once you've figured it out, it's easy to switch to wasted spark coils/coil-on-plug setups.
I do believe you can use the stock igniter unit to interface with megasquirt and just use the stock signal from the distributor. Then you only have to fuck around with the dwell settings and hope you dont blow up your coil before you get it right.
