This is indeed great information. I wonder though if anyone has come across any information about the J3 port on an EEC-IV? I am not looking to tune my engine, but I would love to be able to view and log data such as coolant temp, rpm, and a few others. My engine is a 351W running SEFI with a computer from a 91 Mustang. If I can figure out how to get the data from the J3 port I will write my own application to display the data I need.
Thanks,
Matthew

Well I am more inclined to build my own hardware than buy it. My purpose is to gain knowledge as well as the logging. So if I can't get the information from the J3 port like QuarterHorse does, then I guess I will just have to tap into the sensor lines at the ECM connector. I just finished connecting my own hardware to the CAN bus in both my 2011 Focus, and my 2004 F150.

There is loads of info out there on these EEC-4 computers..

Since then I've been disenfranchised with the OBD-1 EEC-IV tuning on our trucks with electronic controlled transmissions. However, I have been wanting to plunge into Tweecer...as I have a bunch of go-fast goodies in the garage for the SBF I'd like to entertain. Until I can nail down a kit that can hold the gears longer for the E4OD, I won't try it again.
Also, you would need to get your binary code off your pcm to see if that particular strategy has any definition support. Some definitions are free, some are pay for definitions, depends on how common the strategy is. Most of the major Mustang 5.0 strategies are free. I had to pay $25 for my strategy from the developer who reverse engineers the ford code so us common folk know what the heck we are looking at.
My only problem with it now, is it shifts too conservatively. I want it holding 1st and 2nd gear longer. I've driven an F250 (EEC-5, or OBD-II) with custom 5.8's and E4OD shifting program, and it was a beast. However, the tuner only had the capability for OBD-II transmission tweaking only....
Cheers,
Mike

Remove and desolder the connector off the circuit board then solder the wires of the harness connector to connector off the circuitboard.
Now you have a basc EEC "extension cord" and you can tap THOSE wires at will, without messing up your factory harness.
You can monitor almost all of the EEC lines with high-impedance op-amps as a buffer, then either use an A/D convertor to read analog signals or a basic circuit to convert to true digital to monitor pulses and pulse widths.
You can actually buy these... every so often you'll find one on ebay and it's called a "breakout box". I made one because at the time I only saw one listed on ebay and I wasn't awake at 3am to snipe it.
If some of the connector spots are empty, you can easily fill those by cutting off a second harness connector of another car, and moving the wires over to fully load one EEC connector 100%.

OK here are a couple screen shots from my tuner setup to show you guys some of the capabilities of this gear. The first is the dashboard where you can monitor a range of parameters in real time. One of the limitations of the Tweecer is that you can only datalog/monitor about 16 parameters at a time and that is why you see some blank windows in this shot. I was experimenting with dual O2 sensors at the time so I was monitoring the injector and fuel map parameters for both banks(all that stuff in the middle) so I had to turn off some other things like the TPS and EGR, it's a minor inconvience that doesn't really impact the power of the system. Also note the AFR reading right below the Speed and RPM windows, this is from my wideband O2 sensor that seamlessly patches into the Binary Editor software.
The next picture is the base(sealevel) spark table on the Tuner page. Changing the spark parameters is stupid easy here, just highlight a block in the table and change the number.. or highlight a whole section of the table and add 3 deg to them all in one step.. for example. A cool features of this software is that if you switch to this page while dataloging you will see a highlighted block following the actual spark advance being applied as the motor operates. Another great feature is the ability to easily compare binary files(tunes), it's not shown in this pic but if for example I was to click the button labelled "c3w1new.bin" in the "Compare Binary" section at the bottom the software will put the spark table for that tune up next to the current one and highlight any differences.
This next pic is the MAF transfer curve. This is one parameter that has a hugh effect on how the engine runs and again it's all too easy to modify by manually changing the kg/hr numbers in the second column on the left or by importing the data from a file. With this you can use any MAF meter you like as long as you have the response data for it.
In all cases here once changes are made you have to save them to a binary file and burn that in a memory location on the Tweecer hardware(the TweecerRT that I have has 4 memory positions selectable on the fly from a dash mounted rotary switch). Burning the file to memory is done by pressing the button with the red down arrow in the Tuner window at the bottom which only takes seconds.

Do you have access to a binary file with any of those transmissions?
Any help would be appreciated
Mike
p.s. Anyone know if either of these tuning strategies could be used with a Baumann transmission controller?

Agreed the E4 "brain" is puke.
My first change would be the damn TCC kicking on and off with the throttle...swear it turns off the TCC when I apply throttle, then kicks it back on second later...so if you are on and off the throttle in traffic, is it always VROOOOM, vroom, VVROOOOM, vroom.
Just leave the SOB ON damn it, until I brake or throttle to a point the load calls for it to be off. I has to be a very simple logic to manipulate.
Oddly enough, I build E4s, and tons of AOD/E/4R's for performance use, however never got into the tuning.
A line pressure increase, and small spacer in the accumualtors makes a ton of difference on how the trans feels and pulls. A converter makes 100% difference and makes the E4 worth having.
Of course if it was up to me, the F150 should have never had the E4, it only needs the AOD/E/4R. If I could swap the 4R into my F150 crew cab I will.

I have the 4r70w electronic controlled transmission and I can change basically anything with my Quarterhorse through Binary Editor....including shift points, line pressure, tcc lockup. Do you you know what box code you have on your PCM? I'll try and get a screen shot up of some of the transmission scalars for my '95 with 4r70w.

I have considered the Baumann TCS controller, but I always ***umed a proper tuning platform would have the ability to change these parameters as well without forking out another $750 to tune just the shift points.
HOG1 is the code on my PCM. It's a rare PCM as a 1994 California Emissions truck with stock MAF, 5.0 and E4od. But any OBD-1, 5.0, MAF, E4OD binary should work.
Thanks much 73FOMO! Very much appreciated.

IS there a perameter that will leave the TCC applied when you left off the throttle, or the TPS goes to idle?
I really hate how in traffic my E4 kicks the TCC OFF when I release the throttle, then when I reapply throttle, it is off, (or kicks off in that split second) only to RE apply the TCC a second later.....if I am above 30mph in 3rd or 4th, throttle or NOT, can it just stay the ***** on damn it! It will kick off when I apply brakes, or apply "x" amount of throttle...but I don;t see why it needs to kick on and off like that.
Plus, if it stays ON, it will create more engine brake effect, which is GOOD IMO!

Transmission tuning rocks! I love that mine is electronically controlled.
