Dynamic Spark parameters are the ones that I was thinking of. I also meant to add to my last post that on my '98 Grand Am with a 5 speed, the throttle follower action is very noticable. $0D/$0E have 16 throttle follower scalars, 5 tables, 8 dynamic spark scalars.
1978 Camaro Type LT, 383, Dual TBI, '7427, 4L80E
1981 Camaro Z-28 Clone, T-Tops, 350/TH350
1981 Camaro Berlinetta, V-6, 3spd
1974 Chevy/GMC Truck, '90 TBI 350, '7427, TH350, NP203, 6" lift, 35s
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?
79 Jeep Cherokee, AMC 401, T-18 manual trans, hydroboost, 16197427 MPFI system---the toy
93 Jeep YJ Wrangler, 4.0L, 5 speed, 8.8 rear, homebrew hub conversion and big brakes, hydroboost, 2.5in OME lift, 31x10.50's---the daily driver
99 Jeep WJ Grand Cherokee limited, 4.0L, auto, 2wd, leather and power everything, 99% stock---the long distance highway ride.
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.

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

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Checked the BHDC 93V8S10 said he has and same thing "-" NM8 so that is also a good bin with no superceded number and would ba a better start.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

Aaa thats no good!
Been looking through some of my bins, though I had others, but there all auto, except for two. :(
BMHK is for the 7.4

99 Jeep WJ Grand Cherokee limited, 4.0L, auto, 2wd, leather and power everything, 99% stock---the long distance highway ride.
I think I remeber that but I put 5.7 VE tables in? Or changed cylinder size and injectors or something back then...
DAM, just looked at BMHK in Cal Data and it is 7.4L leaded fuel, Export too! And superceded to BPRJ...
You got it to go closed loop right?

I'd use a big block cal to start. IMO it's more appropriate for tha big old iron intake and block with slow burn heads. Typically the open loop cals only have the closed loop enable temp set high. Everythign else is usually copied from a stock calibration. Change the CL enable temp and you're good to go.
Mine goes closed loop. Actually it went closed loop WAY sooner than my old 7747 did. I have actually raised the min temp for closed loop just a bit. My engine likes lots of fuel when cold, so keeping it in open loop and a tad rich helps it lot when cold. I think I raised the temp to 100* F.
Your BCC lookup says:
Without NM8 EMISSION SYSTEM, LEADED FUEL
