[Diy_efi] TPI Question

The 1227747 ECM (TBI trucks) doesn't take a MEMCAL. It just takes a chip in a small plastic carrier. The 1227730 ECM takes the long MEMCAL unit with the knock filter and cylinder select circuits. 

So, no, a 7747 chip can't be used in a 7730 no matter what the programming.

Sincerely,
David

  But the question is can they be reprogrammed with a 7730 bin?

    You are asking for 1227730 bins.
    They are not interchangeable.

    So, I did come up with these codes being 5.7L truck engine codes.  Will any of these work for a 7730 ECM?  I think I have an ANLZ at home if I remember right.  Or are they all the same sockets on other ECM's?  Sorry, I am still learning some of this.

      I would be happy to erase and reprogram one for you, if you have a V8 one!

      I beleive I have already a copy of the AUJP program.

        So, I guess the next question, if you can find a stock memcal to use, which ones will work?  Any standard numbers that I could use?  And if I can get one, would anyone on the list be up to flashing one for me to get back up and running until I can pick up a programmer?

          Since the original sized / pinned chip is getting difficult to find new, I use these to use a larger chip.

          With the above hardware and provided software, you can start with the AUJP code and adapt it to your needs.

          Like this ?

          Good luck and send us updates.

          It gets lonely here when no one posts.

          Since joining this list over a year ago, I think I had only seen one email until the past week.  So, I am going to re-ask a question I asked a while back that I really didn't get any response to.

          I have a 91 Tuned Port Injection setup from a Firebird that I installed on my 87 Mustang GT that I drag race with a 355 small block in it.  I was running a stock AUJP chip that a friend of mine had, but he needed it back a few months ago (since they are getting hard to find).  Anyway, what I am wondering is if there is a way to program another chip with the AUJP code, or anything better to run a TPI system with?  I have seen that people have reprogrammed some of the V6 chips with the AUJP code on Ebay, but wonder if they actually will work right.  Thanks!

          Mike
