US ECU's (from memory) generally have an external TCM. And EDIS module. I could be wrong though, it's actually just the first thing that came to my head after reading ^.

So to all future hax0rs of fordmods - find the auto tables and you shall be praised by all sorts of non-hax0rs.

Perhaps try the EL i6 auto ecu?

are the auto tables known in the US ecus?

if so then maybe it will be similar in the aussie versions

I thought diff ratio location had been found by data_mine when he was doing this stuff a while ago

diff ratio scalar is only to trigger the Torque Truncation Table, and nothing else, so unless your running an auto, its useless. The 5ltr EEC's have the truncation table cleared from factory.

The yanks have found the auto tables, however I think its for the AODE, which Im sure Pete (XR9UTE) has stated elsewhere that they run a different strategy, however you may be able to ID the code, and then find it within the aussie bins

yeah diff ratio is important in the auto versions as it determines shift points....

Q. do tables, scalars and functions have lables in the bin code? if so then finding things must be easy if ford used std naming in all eec's

Diff ratio is un important to the EEC for speed reference as it knows your speed anyway due to the VSS frequency, and hence why you need to change the speedo gear in the box if you do a ratio change. What the EEC wants to know is what ratio between the RPM and VSS exists in first gear, so that it can determine converter slip. The shift points have thier own tables according to load vs rpm.

And if you mean, does it say WOTSPRK for wide open throttle spark table.. no, there's no labels of any such nature.

Otherwise things would be alot simpler, these labels only exist virtually.

not trying to be difficult and i know u know your s**t...but from what others have found when changing diff ratios is that the auto will not change up gears until way past redline....this is because shift points are speed based not rpm based...

why would the ecu need to know convertor slip?

Ive yet to see the dramatic differences in shift points when performing diff ratio changes, but I cant argue on that one as Ive only done it in manual cars.

Converter slip is used to determine if torque reduction is required or not, and its used as gearbox protection, Ive heard that AU XR8 Autos can have a hard time on the dyno due to the torque being reduced (although it may have been an excuse for poor numbers)

When I changed diff ratios with my auto, I didn't notice much if any at all shift point difference.

so how do u know when u have found something?

when they yanks started playing with the A9L's, they pretty much had to play and test, some things stand out, such as tables and maps, but scalars and switches are a lot harder to find as they are only a byte or a word in length. Some of the US guys were really quite clued on in the computer game, and managed to roughly disassemble the code, but you need to know a lot more than I do about it, any comments here Dima??

hi kids, been out of the country for a while so sorry about the lack of replies

to answer a few q's:

- the 6cyl defs dont have dashpot settings, or diff ratio. i have a cunning plan here, not sure if itll work though. they arent a huge problem anyway, as the right bin (auto vs manual) and a good ISC will idle fine if the fuel ratios are correct in the lower rev range.

- there are many bins. not every bin needs its own def. some defs work on many bins, the only differences being changes to values (not code). some strategy updates are so small they dont offset any of the data. the defs contain a header which explains which bins they are known to work with. the site has this in a readme file in the same directory as the xdf.

- auto stuff is not worked out. not even sct have this properly figured out. it will be nothing like AOD and i dont have any leads on this one.

- the logging that moates talks about is not quite the same kind we know and want (ala TwEECer). the moates gear basically watch what the ECU is doing on the J3 (i.e. where its reading) and they and trace what its doing, as opposed to logging variables (TPS, ..._). My solution here is to get a WB02 which has some data logging support. most do, techedge and innovate gear has at least 1 channel. I use a GM (voltage based) map sensor to log MAP, tapped into the TPS, ACT, ECT etc etc to log the rest. Jaysen has done similar but his setup is a lot more professional so it proves it can be done and is reliable.

- the link to the boosted thread is on the site, is anyone actually using it? the reason i havent created a forum is that all of the people interested in this thing are here or on boosted. so if you have more questions start new threads here or on boosted!

if anyone has access to an SCT machine & burner and wants to lend it to me im all ears

Hey all, and welcome back mate! I recieved your chip today in perfect (cosmitic) condition. Havnt had a chance to test it yet cause my car is in pieces and the manual isnt installed yet. I cant wait to get it all hooked up though and have a play, althuogh I have really no idea what to do at THIS stage but I'm pretty good with a computer so it shouldnt take long to understand it all and get tuning?

As for tuning, what do I need to hook the chip up to my PC? Is that what the 'programmer' does or is that your homebrew tuning software? I would like to get everything setup asap so if you or anyone else knows of a place to get the wires, let me know.

Cheers,
IR

You will need a Programmer to program the chip (hence the name!). They aren't quite ready yet, I am testing my current production unit while waiting for a few more to arrive before I can start selling. They are going to list for $90 shipped.

There is no 'homebrew' software, the TunerPro package I am using to tune is a very well written product which is free for personal use but comes with a nag screen in the RT version (which is required to use the programmer). Registration is only $30US.

Tuning is a bit of an art and I wouldnt start with an expectation that itll be easy to pick up. Making small mods is simple but understanding their effect is difficult and requires much time and proper equipment (WB02 etc).

Righto, any idea on an ETA? Just cause I'm curious What comes with the 'Programmer' is that the J3 and Com(Serial port or whatever, USB maybe?) port connector?

How long you been in the tuning scene? Is it hard to pickup or does it just kind of snowball once you get started?

Also, how far do the capabilites of your chip extend? are ChipTorque, PowerChip, etc all J3 (chip type not where it connects, even though it's called a J3 chip cause of where it connects, you know what I mean) therefore with the knowhow and possibly and dyno or private road could you fully tune the car inc. AFRs, Fuel Injection, Spark, etc etc etc?
