Update: Got the verdict back from the guy who tested my ECU and determined it was no good.
The second, non crank trigger unit I sent was OK.
My options are: Use the non crank trigger Accel unit and dis able the existing crank trigger and activating the Optispark........ or bite the bullet and install a FAST system.
I'm not inclined to use the Accel as it is just more "old stuff". But, a lot less costly.
I would like to hear from someone that has installed an XFI 2.0 on an LT1 and get a clear understanding on utilizing the optispark sensor and disc as the cam sensor for the XFI.....and what modifications, if any, are required to the disc. I'd like a better understanding of the installation process before I proceed.
Thanks . I'm sure I'll have additional questions.
