I have a 84 corvette that I was trying to keep some what close to original.
But I hogged out the intake and installed a small cam and long tube headers and a xpipe (no converters)
the car has always run very rich at idle Changed map, 02, temp sender ect.... so I decided to go wit the conversion knowing there is basically nothing I can do with the 1226062.
Problem is after going thru adding 8746 harness (using wire taps in case i needed to revert to original) i have a no start when using 8746 but runs using 6062 ??? I have wiring diagrams and followed them ..
Any one have any ideas as to what to look for ????

Gearhead-efi link for 1228746 Information: http://gearhead-efi.com/Fuel-Injection/showthread.php?306-1228746-ECM-Information-61

Is there a possibility of posting a TunerPro RT data log (.xdl file) of the running rich at idle?
