So little update to this, its in and its running.

Took a lot of time messing about and tbh i wasnt getting anywhere fast with it.
I decided to take it to Romain at racecal, figured if he cant get it working no one can.
Turns out there was a flaw with torque values and TPS, thats been addressed but im still not 100% with it, i got it out on track with the hope of putting it through its paces and off course it rained cats and dogs, so i got some good data and it does work but i really need a dry day to test the speed and response of the downshifts.

some clips of it on track, getting there!

good to hear it's up and running.

So the base firmware for the DSG does seem to work ok then ?

Upshifts sound quite harsh, or is that just the video/camera ?

DSG/DCT/8HP control really is something they should take fully onboard given how popular swaps are these days

Thanks Stevie,

It did but this current fitted box TCU is flashed with a "stage 4" retrofit file from TVS, as the box is fitted with the TVS stage 2 clutches.

They sound very whip like but are not as harsh in real world, they are quick and firm thats for sure, but i could remove the gear cut all together and it will just change gear as quick as the clutch change over will allow.

I agree, the 8hp seems to be getting a lot of support, this is no surprise as the high powered FF cars have always been rare, supply and demand i guess, i do hope there is a revision change or two to come as its so close to being perfect!

Interestingly, i have seen a company in the UAE have just swapped a brand new GR yaris with a DQ250, and the few clips i seen of it working seems to be a jump in the right direction!
