NEEDED: 16197427 5.7L Manual Trans bin

**EagleMark** · 06-09-2011

Anyone have a clean stock 5.7L bin for a 427 ECM conversion?

**JeepsAndGuns** · 02-05-2012

Thats the same bin I am using. I'm sure there are probably others, but this one seemed like the easyest one to find.

Only one I know of available too?

BHDC is leaded fuel, Export open loop! And a 7.4L..

EDIT: I was wrong!

BCC Find says without NM8 leaded fuel. So I went back and looked in Cal Data and it has a "-" sign in front of NM8 which is RPO code for leaded fuel. So I was wrong it is not leaded fuel which is always been open loop.

Checked the BHDC 93V8S10 said he has and same thing "-" NM8 so that is also a good bin with no superceded number and would ba a better start.

So I guess it was origanally for leaded fuel under another BCC then just used for closed loop. Weird how Cal Data says "-" and the emmisions catagory is just * ? These 7.4L manual was heavy a commercail truck to start...
So I'd like a copy of that bin please!

Actually, you already have it in the $0E thread.

That's GM's coding straight out of the database. +NM8 = With leaded fuel. -NM8 = without leaded fuel. The key is that calibrations that are California or Federal Emissions certified for light vehicles have to be "-NM8" so the option code isn't usually included. But 8600# GVW and up are not "federal emissions certified" so the NM8 option is listed with the plus or minus sign. BMHL, BRCZ, BDTR, and BDWB are all manual trans, open loop calibrations if you'd like to do some comparing.

So your FINALLY gonna start on this?

I have been reading about this for months now wondering if you were ever gonna put it in.

I will finally have another person running the 7427 with a manual trans. What bin you gonna start with?

**EagleMark** · 02-05-2012

Yeah, me too?

BMHK $OE it's the only manual bin I ever found, is there another one? Think it was your thread that confirmed what I was taught about bins a long time ago from auto to manual having lots of changes not normally seen in simple xdf or software like TunerCat. Guys who can dissemble can find subtle differences but the new XDF v250 stuff has found so many parameters and TunerPro compare function confirmed many differences in IAC logic to begin with.
