Today I swapped in both a fox main/engine harness and an A9L. The timing/ fuel maps make all the difference. NOT an easy swap. But I did get it driveable in less than say 8hrs working on it.
Id reccomend anyone building a track only car think about this swap ( its not that hard, just every thing else; besides the motor, has to be made to work).
Only had to buy a distributor, IGN module, BAP sensor and some wiring to get the sucker to run.
Running a 93 GT harness. I could have gotten away repinning the factory harness, but the fox stuff makes under the hood soo much cleaner. No CCRM, ect.
Anyways, if you had to ask why Ive done this....Its because of all the stories Ive read about people getting their car tuned. Dropping 5-700 bucks for a tune, (that is not adaptable, and may not even be right)...and being unhappy with it. Get a good tuner?---eh, I cant afford to find a good one.
Hopefully the next mod on the stang will be the X303 and GT40 intake, with the 70MM TB I have laying on the shelf. (maybe a smaller cam, maybe not). Hell Im still running the factory airbox.
