6395 7427 8625 Manual Trans Calibration Listing

[57 Handyman]

Philalbar1, I have '92 S-10 4x4 with slightly modified 4.3L and 700r4. I also run PCM 8625. When you say you got your e-fan coding working, do you mean shutting down your fans at highway speeds? I want to know exactly what you did to reprogram your chip to get the e-fan setup running. Would you mind sharing your BIN? Thanks in advance.

My e-fan setup consists of Intrepid fans and two relays. Fan #1 is tied to the AC and the relay is tapped into AC clutch GRN wire. Fan #2 is tied to engine temp and the relay tied to a engine temp sensor.

57, I got the code from the $E6 page that Mark put up, and just followed the instructions. I've got like 9 iterations of bins right now, as I'm trying to get my tune to work with a 5 speed conversion. The $E6 fan code was really pretty easy to work in, you just need to follow the instructions. I can put the hex code in now in about 40 minutes. It adds code to the end of the bin that will output grounds to specific wires coming from the ecm, and that is also included in the instructions.

That should include all the info you'll need. I can send you my bin that I am running in a private message, but it's kind of a mess right now and I really am skeptical about having other people try to run it as I may have messed up a lot of variables that could cause damage.

I can tell you, the Intrepid fans (at least the ones I got) run pretty strangely. I have setup both fans to cool the engine, not the trans since I'm running an NV3500. I ground the relay for "fan A" for low speed, and the ECM grounds the "fan B" relay, which actually turns both fans on high. Let me know if you need any more help. Have you started a post about this, so we don't clutter this post with fan info?

MT8 with a V6??? That's the RPO for the NV4500 in 3/4 and 1 tons...

I have actually seen this combination in the wild at a junkyard! It was an old 1994? fleet order truck for a power company. 3/4 Ton, 8 lug wheels, TBI 4.3L V6, and an NV4500 in all of it's huge cast-iron glory. I never would have believed it seeing the 5 speed shift knob, figured it was a T5 or, even a SM465 with the wrong knob, but sure enough; I crawled underneath it and it was an NV4500!

Truck was for sure all factory built this way, I was REALLY stupid for not snapping a picture of the BCC sheet and grabbing the PROM...

Wow, that blows my mind. Think of all the inertia that poor 4.3 had to spin. haha

I just pulled an nv4500 out of a 4.3l tbi retired construction company truck this past weekend at the pick and pull, using the nv4500 for an upcoming project. Pulled the chip too for the heck of it and it was a 95 BJWT, on BCC lookup it was supposed to be an MG5 manual......

Sweet, and it is a 0D mask. Years ago I converted a 95 truck whipplecharged that had the BS 2732a chip 5 spd into a red/blue 7427. Man what a treat it would have been to have had THIS file to start with. Thanks for sharing.
