If you can get me the binary of the ECU I can tell you where the PATS bit is but I personally have not disabled it and I've been told there are other things that need doing as well as switching it off in the ECU.

Played around with PTdiag's PATS functions? Might be of help there?

I've seen it but I don't have an MSC eepod to test with. Looked into trying to get the software to work with a J2534 cable however I didn't get very far. The exe seems to export all of the J2534 library functions and the eepod msc1 supports J2534 however it looks as though they talk a proprietary serial protocol to the device. Without actually getting one would be too much work to write an intermediate driver that translates it back to J2534 and if you counted your hours by the dollar probably cheaper to just buy an MSC1. One nice thing is ptDiag seems to have been written in C with minimal optimisation/no obfuscation many many years ago, this makes the ASM code extremely readable compared to recent C++ programs which are close to impossible to follow the ASM these days.

I know there is a bloke I was talking to who is buying one though, so might be interesting to see what it turns up on the sniffer during a PATS disable if he still gets it.

I have the msc1 and was testing ptdiag on the bench with a few ecms. Mostly diesel stuff a 6.0 great oak and a 6.4 Powerstroke Siemens ECM. If you want I can hook it up on the bench and you can TeamViewer in to check it out if you like.

I might down the track to check out some of the stuff it is doing. Thanks

Would be interesting.

Ive order a tactrix open port, as soon as it gets in ill shot you a bin of my pcm. At the moment Im looking and comparing luke111 bin (which has had the PATS disabled) to a standard PCM seeing if theres any differences. Does anyone know which part of the bin I should be looking at?

for a BF Auto i did it was
x0 1022- 02 is the checksum (ish)
xo E701-0C 01=on 00=Off for pats alternate you need this off
xo E073-00 01=on 00=0ff for pats switch you need this on

Currently setting myself up to read write the 6 spd auto trans for the FG on the bench and was playing about, I still had a GM t42 plugged into my test loom and managed to successfully read the tcu while connected to a ford ecu oops
Does anybody know of a source to get plugs for the 6 speed auto i have a TCU but no plug.

made a nice logviewer that has expandable hierarchical log views and very high performance. Can accept 1,000 events a second without lagging the UI, it can also run for hours without running out of memory.

Also implemented my tree view and can now open binary files with the new editor, doesn't display them like the POC UI does but not far away now.

We have also mapped DMRs for almost all configurations so that they can be correlated with each map to allow for map tracing. I also plan to have an "enable" field for each map, this way you can see when it is activated if map tracing is enabled. Eg ECT > ECT_SP so you know when and if it is currently active, no more of this guessing which map to edit. Nothing drove me up the wall more than wasting a few hours tuning the wrong map.

Wheels are turning slowing but getting there!

Also made a nice full screen login screen. Not needed for anything yet but was more to teach myself how to use the WinRT fullscreen stuff.

AGAIN AWESOME work Rolls, I still haven't had a chance to test it out yet but will report back when I do.

But yeah you can change different types of tunes on the same type of controller it just depends on what hardware the controller has as to whether it will work, I even flashed a V8 file onto a I6 controller & the car ran & started but only on 6 cylinders so it obviously doesn't have the drivers for other 2 cylinders.

I got a chance to try this today on a series 1 FG V8 conversion with pats removed, cloned the file to a APS232 (FG 5 speed auto I6) ecu. with no success, wouldn't even kick the fuel pump in, with bridging the fuel relay still no fire! seems all these ecus are physically different. wht a PITA.

You sure PATS was disabled properly? There is more to do than just disabling the PATs bit. Try another ECU of the same type and I suspect you will have the same problem.

The original V8 ecu I removed the pats with HPT and it runs fine as a standalone, I pulled the file straight from the running ecu and dropped it straight into th FG 6cyl auto ecu no bingo, i have a turbo FG ecu i might try as well.

Yeah but it only copies from 0x10000 onwards, so it isn't an exact copy, just a copy of the calibration data.

Why don't you just get another ecu of the same type?

Mainly due to the cost, the v8 ecus are selling for up-to $450 on fleabay, a stock FG ecu goes for a lot less. was worth a try.
