I'm not sure the FAST "classic" will work with the Optispark. I do tune one NHRA stocker still using that system, (we are changing it to an XFI), but he uses a crank trigger. If you change from an MSD distributor to a crank sensor you have to send the ECU in to FAST for a firmware update. You need to contact FAST about all this. As for the IAC, you can use it or not. Many races do not, they simply zero that table.
