R34 Gtt Ecu Compatibility

[SWITZER]

Hi guys

Got a couple of questions about r34 gtt ecu"s i have a march build 2000 (auto) and have bought an ecu with a nistune already fitted from a may 98 (auto)

now part number on my ecu is (23710-aa513) and part number on the nistuned ecu is (23710-aa510) now the nistuned ecu was tuned with a z32 which i also bought and have

also wired in and checked thats its working but the car won't start.Now it whines over fine and sounds like one cylinder was trying to fire so i remove all the plugs and found that only number 2

seems to be gettting fuel as that plug was fuel soaked and the rest were dry now the car was runnnig fine before i did this and the car with the nistune was running fine to so is this issue with the different

ecu's i tryed doing some research before i bought it about compatibillty and found nothing so any help would be appreciated.

cheers.

I have a 2001 manual GTT and it worked fine with the standard nistune chip/software so I think that the ecus would be much the same with maybe very minor variations. Not sure what would be causing your problem may be worth putting old ECU back in and getting the one you bought checked out

Ecu connector tight and pushed in at the ends?
