Hey guys,
I was wondering if anyone would know the answer to a question that is troubling me. I am doing a motor swap and it is becoming a mix of parts and years. First off the motor and 90% of everything is from a 95 GT. The vendor I bought my harness recommended to switch to a 89-93 Distributor, Computer (A9L) and Mass Air. Mainly because he had desighned the harness for those years. ( it did not fit correctly BTW)

Here is the heart of my question. I am wondering if the Mass Air from the 95 would be better suited, or even if the calibration will work with the ODBI EEC? The motor is a complete 95 throttle body to oil pan.

BTW, any recomendations as to who can do the tune and deleate all the codes for removing all the smog equipment and AC?

Thanks guys,

I would recomend using a MAF that is calibrated for a foxbody if you are using an A9L computer/harness. I would have no problem doing a custom tune for you which would turn off your smog equipment ect...

Is the motor pretty much stock?

Thanks Jeff,

The Motor is stock right now, I will probaly be adding either LT's or some form of shorties by then though. As it sits it has a 95 motor,TB,Mass air & intake. No AC or smog equipment.

A9L EEC, TFI Distributor, RJM harness, 190lph pump, C4 tranny w/900 rpm stall (loc@900rpm) 4.10 gears (probaly going to 4.88)

Here is the basic guidelines I am fallowing from Ryan @ fordfuelinjection.com

Also, any recomended mods I should add before a tune are welcomed. I thought about rockers but thought I should just do a cam instead. I have talked with Shaun (93Pony)about it some.

I am looking for the most tq I can get from idle 4800 or so for off roading and daily driving with the 38" tires.

Thanks,

900 rpm stall? stock they run 1500 to 1600 did you lowered to 900 for a reason?

correct, for off roading.

A "Low Loc" converter as the builder called it. It works prity good too. In 4 low if the idel is set above 850 it just keeps puling (or creeping) vs. comming to a halt when you come up to an object.

I may see if the computer can some way be set to bump the idel (like the AC does under load) via programing and a switch.
