I've got one you can have.  This has been lying around for a good while and I'll never use it as I'm running a standalone ECU.  I can't vouch for its working condition so you can have it for free. 

PM me your address and I'll get it sent out to you.

Unfortunately, the ECU that Matt kindly donated shows the same issue as my ECU. So, if anyone has a Jspec TT6 with a functioning trac control who would be willing to lend me their ECU to plug and test in my car that would be phenomenal. It'd let me rule in or out the ECU as the problem.  In the meantime, I've just unplugged the ECU to kill the traction control and extinguish the flashing dash trac off light.

I replaced the primary TPS with a new one so that has been ruled out.

Rider, I'd also suggest possibly sending Matt's ECU to someone who has a car with no issue, then they could swap his in and check if it changed?

Even better would be someone local and you could try your original one too as you say to rule in/out the actual ECU's
