Hello all. So, I have a 1994 K1500. Currently has a 305 w/4l60e.

The ECM is a 16196395 with a BCC of BHMC. The gearing is 3.42, RPO code GU6.

I am putting a 350 crate motor in it, nothing hot rod, and I would like to put the correct bin in it. I have the G2 already along with everything I need to tune it, including the 350 injectors.

I have been looking around trying to get the correct BCC and bin for a 94 LO-5 with the 4l60-e and these gears. Does anyone have a good link or any info? A lot of links seem to be dead now.

Thanks a million!

 

I came up with BCC BJLK. Supposed to be for a 5.7 with 4l60-e and 3.42 gears. Can anyone confirm this? I believe I can run the $0D mask in this ecm.

I don't want to get this wrong and smoke the tranny. Like I said, the is a GM crate engine going in so a stock tune should get me going and I can add my tweaks for the cat back and all from there.

 

The BJLK appears to be for vans. With BJLH for the pickups.

Thank you sir!

I had read on gearhead efi think that:
BJLH was for 3.73 rear with RPO code GT4
BJLK was for 3.42 rear with RPO code GU6
BJLF was for 3.08 rear with RPO code GU4

Now, now sure how correct this is? I don't know how to tell what is different for each gear ratio.

Again, thank you sir!

 

I trust the data I'm using, but can't guarantee it. Here is the info for BJLH:

1994 MY, possibly in: C1500, C2500, K1500, K2500 1/2 & 3/4 ton, 2WD and 4WD.
5.7l, Federal, 3.42 (GU6), 4L60E

I noted on a second read you mentioned having the G2 adapter. Hopefully a typo as the '6395 PCM is MEMCAL based and uses the G1 adapter.

RBob.

 

I trust you and your data more sir. Thank you! And yes, that is a typo. I ordered the G1 from Moates for the the chip.

As always, your the man and thank you.
