You might want to read through my thread as there was a lot of discussion on this very subject.

Back in January I was going through the same dilemma with the 16168625 PCM. I had pulled the...

It's been quite a while since I updated this thread so I figure I ought to bring it up to date. I did go ahead with buying and installing a TBI system. I started working with Dave_w (Old School...

Sorry about the long delay in replying. We had a decent sized snow storm here in Kentucky and I got about 16" of snow. Just enough to keep me occupied for a while :jfj:

Thanks for the link to...

Just realized I also need a throttle cable bracket.

If someone has a photo of what a 2" 94/95 tbi throttle cable bracket looks like I'd like to see it or if you happen to have one for sale I'd...

Unfortunately in my case I don't have a firewall. This in a motorhome that has a doghouse cover and the top of the throttle body is only about 5" below the cover. In my situation a bracket similar...

Thanks for the info. Keyair sent me some pictures of what the map bracket looks like and it shouldn't be a problem making something similar. After deciding to make the bracket I found the plastic...

One thing I need to try and remember is stock brackets may not work on my Edelbrock intake, especially since it's for an earlier non egr system.

I think I'll look for the mounting holes next time...

Dave I picked up this coil bracket a little earlier today, hopefully it's the right one!

As far as bracketry goes I think I'm only lacking two things, the MAP sensor bracket and something...

Thanks for the info and tips. Since this is going in a motorhome there really isn't a firewall at the back of the motor so using a factory bracket might be the easiest approach. due to the lack of...

So I'm looking for a bracket AND a couple of mounting studs.

Thanks!

Where and how is the MAP sensor mounted on a 454 circa 1994?

I need the map sensor bracket and so far I'm not sure what I'm looking for.

This map sensor bracket is listed for the small...

Yes, his data did. I have the Caldata program and it shows the prom chip number as well. I just didn't put 2 and 2 together to realize that I could use it for searching. Fortunately the search is...

Ya know, just when you think you've got things figure out someone throws a monkey wrench in the works :jfj:

I had been working on the assumption that you could only search for the broadcast code,...

I am in need of either an ECM 16197427 with a memcal for a 7.4 with automatic transmission or just the memcal for a 7.4 with automatic transmission.

If you have one I'd like to hear from you.
...

Based on Dave w, buddrow and 1project2many's comments it would appear that the 7427 ECM is apparently the better of the bunch. Looks like that's the direction I probably ought to head :thumbsup:
...

I'm not so sure parts swapping is the answer. The tag is clearly a GM tag and has the numbers on it that I mentioned. One thing seems to fairly clear, the 8625 was never intended for use with a...

Dave, I just installed the Caldata program from Tunercat and entered the broadcast code BJFJ that came with the 16168625 ECM and didn't get the results I expected.

The BJFJ broadcast code is...

That's really interesting and odd. The facts I do know about my 4L80e and the 16168625 ECM is they both came from a running driving truck. The engine caught on fire and the owner pulled the engine...

And most likely never will!



Or as happens all to frequently in my case the answer just confuses me even more :mad1:

I've read about the cleaning cycle and the frequency differences. Transmission goes to the shop this Friday although it will be a week or two at least before they can open it up to let me know what...

I agree with that assessment which is why I'm taking the transmission this Friday to a Transmission shop for a complete refurbishment. I guess I'll know what I have after they've had a chance to...

Dave, thanks for the reply.



Could you describe your shifting problems? The 16168625 ECM that I have was in the same truck that I pulled the 4L80e from so I would have expected them to work...

Ok this is my first post and it will probably be obvious I need help! :scare:

For those of you who have read Keyair's thread about his Airstream motorhome TBI project you'll find that I'm...
