Hello All,
I swapped a 98 Explorer EFI 5.0L engine into my 54 F-100. In doing so I deleted the automatic transmission for a T-5 manual. Since I am using my stock gas tank I also deleted the fuel evap. system. The (7) codes I am getting all have to do with the transmission delete and the evap. delete. The engine starts and runs pretty good but it is just not quite right as it is looking for the automatic transmission. I have been looking to have the PCM flashed and reprogrammed but not having much luck. Does anyone know of a good company to contact. I have been told I need a different PCM altogether to work with the manual transmission. I need a PCM/ECM/ECU that will work with the 1998 Ford MAF 5.0L engine using a 5 speed transmission. If anyone knows which Ford vehicle uses this type if PCM or know of a good programmer to make my present PCM work, please let me know.

Thanks for any information you can give.
Bob

 

Check Ebay and salvage yards online. Used computers are cheap. There's no reason to use your existing part if you can find a swap.

 

What 1998 Ford had a 302 with a 5 speed manual? Not the Explorer, F150, Mustang.....

If you have already googled "1998 Explorer tuner", then ignore:

lots of others.

 

Thanks Monckywrench and 85e150,
I have been looking at Ebay today and saw a few computers for 98 Mustang 4.6 engine with a manual transmission. I don't think there was any cars or trucks in 98 that had a 5.0L engine other than the Explorer and those are only automatic. This engine is MAF and the 4.6 engines I have seen are also MAF. Since the 4.6 is an 8 cylinder like the 302. I wonder if the 4.6 computer would know it is connected to a 5.0. I am not sure if the PCM pins for the 4.6 would match the existing 5.0 pins.

85e150, I have looked at some of the tuners on-line but I don't know how well they would work on my present PCM. I have read that all Ford PCMs from 96 to present are programmable but I don't know what all can be done with this one. I would like to get with someone that has successfully made these modifications.

The companies that I have talked to all want you to give them the VIN that the PCM belongs to and the PCM part number. If I get a used PCM without knowing the VIN they won't program it. Maybe they would be happy enough if I give them the VIN from the Explorer I took my PCM out of and the part number of whatever PCM I buy if I can find one for a manual transmission. I don't know if that would work. They would be getting the Explorer VIN and a PCM part number from a 98 4.6 Mustang.

I may have backed myself into a corner!

 

Aftermarket EFI and controller might be cleaner, easier, probably not cheaper.

 

If all else fails there's always a Holly 4bbl. Not the answer you are looking for, I'm not either but I might end up in the same boat, for different reasons.

 

I found out that Ron Francis Wiring also does reprogramming. I sent my 1998 Explorer PCM to them. They received it this past Monday morning, worked on it as soon as they got it and it was back in the mail to me that afternoon. It got to my house by Wednesday, I reinstalled it, fired up the engine and now ALL is just the way it needs to be. If you are in need of PCM/ECM work Ron Francis Wiring is the place to go. Great business, Great people!!! Before I knew they did this kind of work I looked all over the internet and no one would or could do what needed to be done. The price was fair and I am happy!!! Call them at 800-292-1940.
