Firstly my car is a 1993 VR V6 Auto (4L60E)

Im using the following files in tunerpro
Bin: OSE_$11P V104 CAKH V6
XDF: OSE_$11P V104
ADX: OSE_$11P V104 1Bar

I have also tried downloading the bin and using that.
Clearly I have missed something and am unable to make any changes. I have been using it lately to just watch live data just fine but now I would like to make some changes and cant seem to upload anything it just says failed to upload in tuner pro. (started with a simple change like rpm limiter in power mode).

The jumper connections are correct to allow writing etc. The only thing I haven't done was the wire mod on the back of the main board but I thought that was to burn a completed bin to the stock memcal witch I will do at a later date.

Some help and guidance would be greatly appreciated.

Cheers

There's your problem

Will get onto that,

Interesting now I get a high idle and thermo fan running

as soon as you ran the nvram RW without that wire you corrupted the nvram. now you need to put the ds1245y chip directly in to a programmer to put a fresh copy of 11p on it. Thats why we ship it RW disabled and ask you to make sure everything is right before turning on RW.

Sounds like it's in limp mode.

Easy enough to do, I have a programmer in a box here somewhere, will reload the bin back on.

Clearly I mucked this up an guess thats what I get for being to keen and staying up late and hooking it up following the instructions.

Ok so I dug out the programmer and following the guides I load in the Stacked Bin file to programmer and burn it using the GQ-4x4 but still get limp mode, Iv reset all the jumpers back to the supplied position till it works properly. (yes I added the wire) Iv read the file from the rom and verified it with a hex editor and it says it matches. Car starts and runs normal with the stock memcal installed. Any help would be greatly appreciated. Thank You

Tried to burn again, car coughed then stalled next time it started fine and ran, no idea what I done different but all is good it seems,

11P - make sure you have the PCM jumper set, that is a hardware setting required for the '424 PCM.
