1994 Chevy truck with 350, TBI, 4L60E transmission, 7427 computer. What would my stock bin be? I'm searching for one but can't find what it should be. I've tried the BJYM but the trans doesn't seem to shift right. Anyone know what my stock .bin file is?

 

It is printed on your memcal, your using the correct mask correct?

Maybe try BJLH and see how that does, it may not be your exact one but it is from the same combo.

 

Yes, I'm using the 0D mask. So, it should have 4 letters printed somewhere on the memcal that tell me which bin is in the memcal?

 

Yes most I have seen has it directly on top of the blue cover as well as under the cover on the prom its self.

I could send you one that would work via email if you need.

 

Here is a stock BJYL will work on your set up .

 

Thanks for the help. I found a BJLH.bin that I'm going to add my tweaks to and try it. I tune is currently based on the BJYL and it runs fine but the trans shifts are way too weak and the converter isn't locking when it should. I think it is a line pressure thing but since I don't know what to set them at I'm going to try the BJLH as a base. I see it has different line pressure mods and such but most all engine parameters are similar or the same as the BJYL.
