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

Yeah that's what everyone thought and would make sense then a manual bin file popped up! Man I wish I remember where...

But if I can't find one do you think I could just zero out all tranny paremeters in a auto bin file?

I would be interested in a '7427 manual .bin as well if it is found.
I started with BJYL, which is a 5.7/700R4 .bin, for my S10 434/Tremec project , worked out O.K but still "idle hunts" from time to time.

93V8S10 on TGO said he found some manuals at Moates but no V8 ones?
So it looks like maybe the export BCC to start and import some 5.7L paremeters.

and BHNB or BHNC are supposed to be 427 BCC manual trans for CAL because they needed the EGR pintle...

I would just start with any $0D bin that looks close and change the flags for TCC, shift light, Electronic shifting, and what not. I guess there are also some idle paramters used only for Manual Transmissions in the Advanced_$0D_TP5_v250.xdf. That '7427 is one very versatile PCM. I am getting a pretty good handle on this tunin' stuff, let me know when you plan to start tweaking it and I could probably find some time to come by and help.

Since it is going to need a full tune anyway I was just trying to find as close a match as possable to start. It's going on my sons 5.6L IH Engine we are rebuilding now, bottom end almost done.
I think I will take both your advices and see what works best. I know that manual trans bins and engines before bins that had toilet bowels, ah I mean controlled fuel leaks/carburators had some form of decel valve as to not let throttle snap shut between shifts. This is why I wanted to start with a manual bin.
From looking at defs made for this ECM/PCM the $OD does look like the most advanced but I did not see any paremeters for the manual shift decel valve situation, is another reason I wanted to start with a manual bin file. Sure lots of auto tranny choices and ons and offs, but no maual decel stuff... it may be there and work fine, all it does is slow the rate of decent of RPM between shifts. I beleive this was first installed as a emmissions device but ended up being a advantage to driving a manual trans.

Yes, throttle follower is used extensively with manual trans, But there are some dedicated idle routines to handle a manual trans. In the .xdf there are some tables that state in the description they are just for manual a trans. I think they are near the bottom of the tables just before the 4L60E stuff.

Well good! Then I should just start with a 5.7L anything $OD Right? Wonder if they have a BCC for export? I have heard they run better than the ones for CA or FED. With as many options as there are with $OD I guess it doensn't matter...

I've done six '427 type PCM's upgrades / conversions. For a Manual Trans and Non TCC Auto Trans (TH400 / TH350) I like $OE. For the 700R$ Auto Trans I like $OD. I attached a copy of the $OE BHDC.bin I've also been working with Excel, learning how to Record a Macro, so I can sort the data logs for both Near Idle / Off Idle tables.
