Yeah that's the route I'm going, WB02 fed in to the 7427 and an Autoprom. I'm fully expect mine to be a one and done though, that's why the ELB looked enticing. As it is I'm thinking about using my...

Good info! I've been tempted to reach out to Brian at TBI Chips as I read he has the CAJR .bin, but I don't know if it's worth $300 haha.

I was looking at those after our WB02 conversation, but it looks like 7427 isn't on the list. What a bummer!

Right, it's a '95 TB with '87 injectors.

It looks like BJKX would be the latest, and is for a truck so I'll start there. In '95 it went BMHM->BPRK->CAJR, and I imagine that might prove difficult to find but I understand there were issues...

Hopefully Dave never gets tired of swooping in and saving the day! Just to make sure my understanding is correct, C=2wd, K=4wd, G=van, P=medium duty? In which case BJKX or BHDF would be the best...

Ah, SD it is haha! That's cool about the cruise signal, I left a lead for it as well even though I deleted all of my cruise stuff, I'll have to dream up a good use for it.

I'd love a timing table...

I was planning on keeping SD for simplicity and convenience, but I'm certainly open to persuasion haha. One issue I've run into with the 4l80e and 7427 is that sections used by other people for...

Hey guys, I've been driving around my '91 Suburban with the 7427 swap for a couple of years now and it's been great with the stock '95 5.7/4l80e tune. I've been slowly gathering the parts and making...

So I worked out deal for my nephew on a '94 V2500 Suburban that has the 7.4l with the Whipple Supercharger kit installed. I nearly bought a Whipple kit a while back for the 5.7l in my '91 V2500 Burb...

Thanks a ton for your help! I just ordered a temp sensor.

Uh oh. Well I'm running the 5.7TBI with the later force motor (93+) 4l80e. Is there another memcal that will run that combo? Or should I buy a screw in temp sensor?

So I was able to find the location using TunerPro's hex editor. Should I be worried that the location is already "occupied "? I also still need to figure out how to adjust the...

So I did some more reading and have got a .bin editor with my .bin loaded, but I'm not seeing the location referenced in the word document. Perhaps I'm using the search function incorrectly in the...

Some quick background. I did a 7427 swap on my '91 Suburban some time ago and it's been running awesome on the .bin below. I am getting ready to revamp my cooling setup in anticipation for a big...

Thanks Carl, I got a chip installed with the .bin you corrected the checksum on and the blink is gone!

For those of you who didn't see my first thread here is a quick recap; I wanted to swap my '91 Suburban from the 7060 to the 7427 because my transmission needed a rebuild, and I wanted to run the...

Yep, coil on plug. I will be using the 8.1 ECU.

Daveo91, I will need to PM you once I have had the '94 I pulled today inspected.

Interesting. So help me understand; you ran the later force motor with your 7060 instructing it to run the cleaning cycle and didn't have any issues? I came across a post where a guy claimed he did...

Darn, I had a feeling it wasn't going to be that easy haha. Well, I will look in to the info provided. Thanks again!

Hi all! I have a question I desperately need help with. The 4l80e in my 1991 V2500 Suburban just blew, and normally I would just get the trans rebuilt and call it a day, but I've been gathering parts...
