WHOOO EEEEE!
You can do it Bobby, kudos my brother. I am impressed in your knowledge and aptitude.

I seem to recall Decipha had a method of not requiring a TCSM.
Do you have one?

Neto, just out of curiosity what is decipha?

Rudi,  Decipha is a guy who is a proponet of open source tuning software.
And he's good at it.

I do have one of those "Very Rare" little boxes.  It worked just fine while I was in the modification/testing stage with the shifter and wiring.  Now...no workie.  I'll be on it today I think, let you know. I don't recall reading or hearing about a work-around.  Thought of making a relay ckt at one time back when we were doing your harness. A simple on/off switch would work too it it got right down to it.

Rudi:  You can read more regarding Decipha's work at "EFIDynoTuning.com, if you wish.  He runs a dyno shop in Louisiana and has broken out many GM and Ford EFI stratigies and written calibrations that can be loaded into emulators hardware such as the "Tweaker", which Barry is using and the "Moates Quarter Horse" which Tubo and myself...and maybe others on here... are using.  This is like a "Chip" that can be plugged into the factory EFI computer and with the open source calibration can be "tuned" to the requirements of modified powertrains.  I believe Barry's engine/transmission are stock '95 but due to the rear gear change the ability to tune shift points is required. 
My engine has AFR heads and a cam and the transmission is an '03 which has a wide ratio gear set instead of the earlier C4, AOD, AODE ratios.  So I found it necessary to tweak the calibration for the EFI and the behavior of the transmission.  Decipha's work plus the Moates give me that ability...if not the smarts...to do that.  But I learn a bit more every day.  
It keeps the juices flowing and at my stage of geezerhood that's important.

Thanks for the answer guys, too complicated for my old brain to delve into. Must be something akin to all these kids with ricers tuning up them up with a laptop.

Yup!

LOL, 100 mph on the freeway in a balogna piped Honda with a lap top in the pass seat punching in numbers chasing that elusive miss at 7500 rpm.

I don't think there's any connection to the loss of 12V to No. 1,2,3 injectors and the failed engine.  The break in the V-Power circuit in the main harness was defiantly my fault during the change to the 4R70W transmission wiring.  That circuit comes from the EFI relay and branches to everything in the system that needs steady 12V.  Those three injectors all got fed from a broken wire at a splice off the main ckt.
And even after the main bearing failure last July the old engine ran smooth with no misses.

Bob:  It is a good feeling.  I've been getting really horny to drive that thing...just gotta have a regular "fix" or I just ain't right.

Thanks Barry, looks like they just used an On/Off switch to kill the 3/4 shift and TC lockup.  Seems to me that Ford came up with the TCSM so they could use a flip/flop ckt controlled by a momentary switch rather than an O/F.  But the EEC-IV didn't have the room to add that ckt, hence the extra box.

Well, I  have one and it works just fine so I'll keep it.  BTW, found a broke wire in the shifter where I modified it for the switch.  Did a bit more modifying yesterday and I think it will be okay now...time will tell.
Played with the idle per Decipha instructions and it seems better.  I didn't know that the CBAZA had decelleration fuel shut off and thought I had a problem but no...that's what it's supposed to do.  I'll drive it a while and see if that's too annoying.  Can always disable it or adjust it a bit.
I need to get the wide open throttle fuel dialed in but need to get some miles on it before putting my foot down.  As it is now it seems to run very well so I may just rack up some miles then see what fuel is doing on hard acceleration.  You drip-can guys just don't know what you are missing...LOL.

More to come.
