Need ECM for 5.0 MAF engine

Here is the problem I have a 1991 5.0 HO motor with a T5 tranny. I thought I had a MAF ECM from the 1991 but found I had a Speed Density computer ECM. So now I pose the question what would be the best ECM for me and from what vehicle? Do I need to get a computer from a manual tranny vehicle or can I use the one from a Automatic? I know the auto's have a higher performance computer. My truck is a 1960 Ford/Merc and I would like to get a 93 Cobra ECM but is it worth it trying to get it or should I just get one from anything that would work. I plan to get a programable computer later (ie AEM) but just want to get most of the bugs figured out prior to that jump. Any info would help and just to let you know the truck is going to be a daily driver and due to fuel costs I would like to stay with the EFI.
Thanks Butch

If you just want to get the motor running as it is right now the SD computer will be fine.. all you need is the matching engine wiring harness for that computer. Stangs were sequential fire SD in '87-88, and MAF from '89 on, these are best performance options for you. The Cobra was calibrated for 24lb injectors so you would need to change these to make it work optimally. Some '94-96 light trucks(E150 and F150 series) were also EEC-IV SEFI mass air, this ECU/harness will also run the HO though calibration may not be as agressive as the Stang version. OBDII also appeared on light trucks in 96 so you would have to be carefull to double check or this. You would want a manual tranny version BTW, the later automatics were computer controlled and would throw codes if they don't see the tranny.

Thanks that helps out a lot, tells me where to go. I believe the 89 on computer for the 5.0 stang would be best for right now and they don't cost to much and I have all the sensors for a 91 5.0 MAF. Thanks for the knowlege about the tranny. I just wish I could use the computer out of a Crown vic so many out there at the junk yards.

Well I need a ECU. I have a 1991 5.0 engine with stock injectors right now but I have no problem getting the 24lb hr injectors. Right now I will be driving the truck with a T5 tranny might upgrade if it has any hint of a problem. So a simple Mustang Mass Air ECU for a manual tranny would be fine. I would like the Cobra ECU but the cost could be prohibitive. If you have anything that would work that would be fine.

Thanks for the reply

if you go and get a coimputer from a mustang, try the get the A9L. from what i have read, they are one of the best computers. from my understanding, they have the most aggressive programming for the 5.0. good luck. also, hop over to the 60 forum. there is loads of info there on the old trucks.
