By what I've read on different posts, I'm correct in understanding that if I pull a complete TPI setup including harnes, computer and sensors from an 86 305 / 700R4 and transplant it into an 86 carb 305 / t-5 that it won't work? or should I say won't work without reprogramming the computer? I've never fooled with fuel injection or computer cars before so I am totaly "green" on the subject but I want to learn. Is there an "easy" way to do it?

 

Yep, it will work.

 

Are you saying without any "reprogramming" the ecm from the 700r4 or with reprogramming it? I'm not concerned with horse power or anything right now, just keeping it stock with stock TPI set up.

 

It will work without any reprogramming. Might have some idle down issues (deceleration), but it shouldn't be too bad. I ran a 700r4 eprom for a while with my T56 without any problems at all.

My situation is similar as well. I have a 4L60E so I have my original TBI computer running that and then the '7730 running the motor and it worked perfectly fine back when it was just a stock chip minus VATS. But there are plenty of people out there that will burn you a chip with just the "Transmission" value changed from Auto to manual (assuming the MAF computer is similar to the 7730 in that repect.)

 

Well, it's not just as simple as switching a value in the .bin......there are other differences in the .bin files when you compare an auto to a manual.....they are small, but there are diferences......that being said....his set-up should run fine on the auto prom chip.

 

Thanks for the info! I was scared there for a minute and was about ready to scrap the idea of changing it. Me not knowin much about computer controlled vehicles and fuel injection, it would a hard learn to trouble shoot if I did have problems. I've always been afraid I would fry something. What would it cost to have the prom changed?
