That’s the one. Yeah, the seller has confirmed the base ECU is from a manual car. To be honest, I’m only worried about the TCS light being illuminated due to registration here in NL - unsure on rules. Back in Japan, we weren’t allowed to have any permalit error-related lights (or so my shaken guy said). Looks like this Nistune is the way to go then, appreciate it GTSBoy, and the others that chimed in. -

There is no impact. Granted, mine is in an R32, so there are a couple of other things going on, but.... my auto ECU came with the auto engine. Bolted it up to the manual gearbag and suddenly the TCU is just spare parts along for the ride. The ECU doesn't (really) care. Nistune is the fixer of all wrongs. I have no ABS CU or traction control. That would be a recipe for fault codes and permalit check engine light. But....just go into the diagnostics pages and turn them off. Presto, ECU no longer cares that it can't talk to those CUs. If you're worried about the TCS light being lit on the dashboard for some rason (that I am not catching right now), then.... remove the globe. No-one needs the TCS anyway. That is what throttle control is for. I certainly don't have it - haven't missed it in 12-13 years or so. Never wanted it.

Thank you Duncan, and I will say, before reading GTSBoy’s response, this was more or less my logic. I can’t argue with that. The part I couldn’t get past was thinking that the speed sensor in the 30A was replacing whatever was in the AT transmission before, and therefore completing the prior circuit. The other thing that I failed to mention was that, across all HKS documents, despite mentioning compatibility with AT R34s, there is no mention of a different pin. These Japanese instructions appear to predate early man, so there’s always room for error. I’m speaking with the seller of this R34 GTT ECU with Nistune at the moment. It’s pretty cheap and eliminates the possibility of me soldering my fingers to the ECU when installing the board myself. I am yet to confirm whether the base ECU is from an MT or AT car, so the question is: When using an MT ECU in an AT car, and then losing the TCU part, are there any other implications? Another thing I’m not sure of is whether I can pass local regs with a TCS warning. Of course, swapping between ECUs is a fairly simple task. -
