will installing a gts4 manual RB20det ECU to rwd gearbox and rb20det auto engine loom cause any issues? any known sensors needed different from rwd rb20dets?

currently I have an ecu (likely auto) with an auto engine loom (if they are different from manual looms), but its wired to a rwd rb20det and gearbox and starts perfectly fine. I got a gts4 manual rb20det ecu but it doesn't start the engine, if I get a lucky start I have to hold the gas pedal but once I let go it will not start again at all. Would I have to change the cas timing? tps readjusting? idle air screw readjust?

Post up the number of your original ecu  - someone may be able to tell you if its an auto one.

In any case I would use the one that works. You may be able to get it Nistuned later if you start modding.

Shouldn't have to change anything. They are the same thing. Auto ECU will happily run a manual. GTS4 ECU is same same as RWD. If the GTS4 ECU is not running your engine, it would suggest that there is either something wrong with it, or perhaps it is already Nistuned or otherwise reprogrammed for different sized injectors/AFM or something.

i don't have the number for the ECU I am currently using, got it like that. I don't mind if that one is auto or manual it is working fine, the second ecu I got is gts4 but as my backup ecu, it is not working.

thanks GTSBoy, I really just wanted to have a backup ecu. I bought this gts4 manual one from ebay, turns out it is no good. I see no signs of nistune in it at all. It can be nistuned but I'm not ready for that yet, I just want to ensure I have a backup ecu, and if I do get the nistune chip the ecu should at least be working, in this case it isn't.

      Manual Shifter slightly bounces/moves/vibrates when accelerating/deaccelerating

      Congratulations on your find  Did you mean it has 6k miles or was that a typo? Firstly, keep in mind some movement of the shifter is normal...it is a long rod hanging out of a box bolted to the engine. Having said that there are 2 next places to look: 1. Transmission and engine mounts. If these are worn or broken the shifter will move around more. They are reasonably easy to source and replace on a hoist, and possible but uncomfortable to replace car stands 2. On the bottom of the shifter there is a nylon cup that sits over shifter's ball end. If this is worn or broken the shifter will move around more than it should (but will still shift OK). That is a cheap part and requires removal of centre console, rubber shifter hole covers and a circlip in the gearbox shifter hole to remove the shifter. Re maintenance, as with any new import you should change all the fluids including transmission when you get it; never trust the seller and previous owners to have done the right thing. I am pretty sure R34 GTT is the same as earlier big box transmissions, so use any good quality GL4 75w90 trans fluid if it is shifting well (if it is hard to shift due to synchro wear, redline shockproof lightweight will keep it alive a bit longer before rebuild is required)

      Misfire/stalling issues

      Well considering I have the exact same problem with that as the original one I don't think that the ignitor is the problem. I would imagine that this being such an uncommon problem the possibility of getting a new ignitor that is bad in the same way as the old one has to be very slim. I'll definitely pull everything apart this weekend and check the turbo out. Got quite a bit of things to check out Saturday like fuel pressure and the pcv so I'll report back once I do that.  Thanks everyone for all the replies this is all really helpful

      Rb's have issues with bottom end starvation, not head starvation. Which either way, you probably wouldn't ever see on a dyno. Strange... What's pump gas for you? Octane rating?
