    16197427 and a 700R4 ?

    Just wondering if a 16197427 ECM is capable of handling the controls for a 700R4? I know they will do the newer 4L60E and 4L80E and I have even seen a manual transmission bin for them but not seen one for the 700R4...

    Yes they will, there is a certain selection of bits that needs to be set and a couple values changed. The XDF that was made by 93V8S10 has the needed changes in the description of the tranny related items. I believe this XDF is available for download on the Tuner Pro site. If not it is posted in a long thread that talks about $0D on the Full Size Chevy forums.

    Bringing this thread back up.
    Does anyone have any more details on exactly what needs to be done to make the 7427 work right with a 700r4?

    Long story short, I have a coworker I have been doing a little tuning to his 92 1500 with a 350. His stock ecm is a 16146299. I looked over his truck and harness and it appeared to be the same as a 7747 system. So We plugged in one of my eeprom modded 7747's and it runs perfectly fine, everything works just the same. I started with a 88 350 auto bin and have done some tweeking of the timing table and a couple datalogs to keep an eye on ping. He says it has made a night and day diffrence in how it runs, how much power it has, and even its fuel mileage. He says he has owned it since 93 and it has never had that much power. He said his fuel mileage went up from about 12-13 up to about 16-17. (he is a older man, and doesnt drive like us lead foots...lol, but likes power when he needs it)
    Seeing how much of a diffrence a 7427 made to my jeep, we are both really curious if it would make any diffrence to his truck. I have a 350 bin file I read from a memcal I can start with, if I can make it work with his 700r4.

    I believe I posted a .bin or at least the BCC for a factory 700R4 cal for the 7427. Maybe it was even BJYL. I'll look around.

    Wow, interesting. The stock 350 bin I have is that BJYL. I read it straight from the memcal. Its the stock bcc that was in the 7427 I am running. It was also the one I was gonna start with.
    So that bin is alreaday set up for a 700r4?

    Confirming...

    The BJYL 350 tbi 700R4 cal that is attached above appears to be set up for 700R4. Stock BJYL is not set up for the 700R4.

    The BJYL should have parameters similar to these.

    These parameters need to be configured.

    In these pictures above, has that BJYL 700r4 bin already had these changes made, or do I need to go in and make those changes?
    I should be able to find all those scalers and change them to whats pictured above. But that hex box scares me! I would not have the slightest clue about doing that. I would most definately mess something up there!

    I have not had a chance to look over the above bin and defination yet.

    I remember checking that manual trans flag and setting that table to zero for the bin I am running in my jeep.
    On this 700r4, do I need to check both of those boxes, or only the "tcc only" flag. And if I change that table to zero, do I still need to do something in that hex?

    I honestly can't answer the questions above and say the 700R4 will work. I'm still working on making the one '427 / 700R4 conversion I've done work! Here is the tread I have going at FSC:

    http://www.fullsizechevy.com/forum/g...ade-700r4.html

    I think I've dotted all the "i"s and crossed all the "t"s and my '427 / 700R4 conversion is not working.

    Just a theory! But your taking a PCM designed for 4l60e and running a 700r4 hack, then turning things off for 4l60e so something may be interrupting the VSS speed to transmission or something is not set correctly for VSS speed to transmission? I did not follow closely enough to see what/how/why you are using for the TCC. You say switch for TCC is on? But no lockup?

    Why am I bringing this up? Because I had the same issue in a $EE LT1 with 4l60e and no Torque Converter Lockup. Trans shifted fine, speedometer worked fine. In the $EE XDF was three scalers for VSS. I don't see any equivent in $OD. The one I ignored because it was listed as "Speedometer Scaler (scan tool)" was exactly what the transmission was seeing. I only found this when driving around with Scan Tool hooked up watching data of trans. TCC switch came on! No lockup! Looked at transmission speed in scan tool and it was 18 MPH (not enough for TCC lockup) and speedometer on car was 40 MPH. I think I felt it lock up at 80 MPH on car, but hard to tell at that speed. When I fixed this scaler, the vehicle speed and transmission speed were the same and TCC worked. So in this case even though TCC switch was on, there was no lockup. HTH!

    So, after all this time, has anyone had a confirmed successful attempt at running a 700R4 with a 7427?
    Me and my co-worked are still curious to try a 7427 swap, but I'm not gonna waste my time hooking up my adapter harness and starting on a bin for his truck if I can not get the tcc to work as it should. Auto trans parameters are over my head (I'm a manual trans guy myself...lol)
    So hoping by now someone may have gotten it to work and would be kind enough to share the bin file.
