LC2 based Turbo V6 with Fast XFI
I was thinking..... if you have a car...... that isn't running right or is refusing to crank in SEFI mode, can you simply just put in in bank to bank mode (in the fast settings) and crank it to help confirm or eliminate the cam sensor as being an issue. I would assume it would not matter if you left the cam sensor plugged in or not.
In our case.... this car cranks sometimes..... but currently it isn't cranking... so I can't just unplug the cam sensor after it starts and force it into bank-to-bank.
I read (in the XFI help) if you do this, that you need to zero out any individual cylinder timing corrections as it will still be making the corrections and it doesn't know what cylinders are what without the cam sensor. I'm having a hard time wrapping my head around this because it knows when to fire the plugs......it knows when #1 is at TDC...... what it doesn't know is if #1 is on the compression stroke or exhaust stroke..... since it is waste spark.... it shouldn't matter.....
Any thoughts?
