$85 7060 "Choke AFR Enrichment at startup"

[chevmasta]

You know all Axxx.bin were superceeded to Bxxx.bin? AWAW is now BAMT.

Mark,
noOB question...
How do you know which bin supersedes to another? I've seen you post this to several people with various bins....

Is it just a matter of the BCC find? How do you correlate each of these superseded bins together?




Back on topic...
Today my truck didn't like itself on hot startup....twice. IDK why.....I can tell it was running rich again on startup. But it does it randomly. I think I still need to remove some more fuel from the VE table on startup.....and/or maybe I have an injector leaking down? Might be a hard one to chase down.

I have a few SnapOn books that I double check TunerCat CalData program for bins.

Cold start is a tough one, only get one chance a day to test. Mechanical issues just can't be tuned out without messing something else up. One thing that does affect TBI cold start is throttle blades not open enough. After a drive watch your data, always do idle data at end of log. What are IAC counts? If under 20 your good. If higher it may be cold start and other issues. As TBI wears the blades close. Fuel does not mix with air as well and all air is coming through IAC.

Mark, can you tell me if a 7060 ECM with a BDPK EEPROM will be ok to use instead of my AWAW? It is from a 4L80e truck and I'll be using my BAMT bin. Thx.

That's a 5.7L Memcal. Not sure how the knock filter will react, there's been lots of discussion but I never saw a clear cut answer. I don't mix stuff like that...

Good enough reason for me Mark, thanks. I'll see if I can find an AWAW for a reasonable price.

Since your doing the chip part I would use any Memcal for the 7.4L, the knock filter in it will match the knock sensor in motor which matches the engine size.

Three parts of a Memcal, chip, Netres and Knock filter. Netres is easy and the 5.7L would work, CHip you've got covered. Now knock filter?

Someone will correct me if I'm wrong but I don't think we ever came up with clear cut answers on Memcal Knock filters, we do have a list of many. I just don't play games there as it may or may not detect knock properly.
