Quick question... ECM compatability...

[safariobsession]

I have the 16144288 computer on my 91 TBI engine. Everything i've read shows you can just swap in the V* PROM into the 7747 computer, but nothing about swapping into a 4288 computer. Can I just swap in a 7477 computer in place of mine?

I swapped in the 7747 computer on my 1990. I don't remember what the # was on the stock puter (was not a 7747) but the 7747 from the v8 I had swapped right in and I installed a new chip from TBIchips.com.
Van runs great and passes emission testing.

Cool, thanks a lot bikehauler! Just trying to make a big list of swap needs and info before diving in! Now i just have to get this 350 to the machine shop or find a halfway descent one ready to run!

Find a good shop and get er built!
If you have a shop you know do the work you can have the motor built to your spec and you will know what is in it.
When you buy a runner you never really know.
Or you could always buy a crate motor. They often offer the best value.
Soo many choices. Man I wan't to do another swap now. Thanks a lot!

I'm currently doing the V-8 swap with a friend of mine. He picked up the 7747 computer from a local yard yesterday and it didn't even come close to plugging in. (It was from a 90 V-8 pick-up and we have a 93 van) He went back today and asked for a computer to a 93 V-8 pick-up with 4L60E trans and it plugs in. I'm hoping to get a chip for this computer if it works. We should have done more research first..............but where's the fun in that?!

Bikehauler, I've been to two engine shops nearby and one told me to go to the other one, haha. I talked the guy/owner and he seems like a good guy. Been there twice. Last time he showed me around the shop and answered all my "newbee" questions about cam compatabilites, etc. Says he knows he's a little pricey (as what others say), but other shops say he's the best around. ~$1075 for machining block and heads. I should really start a swap thread and give some details. Yea, buying a crate motor would be quicker, easier, but building one and saying I DID IT sounds so much better!

SCPerf, thanks for the heads up. I'll have to look for the same year and note my connections.

It might plug up, but you have to make sure all the pins are in the right spot....look over this and compare,click on to enlarge
