Please Help R33 Z32 Ecu Troubles :(

[hybriduno]

hi all thanks for reading!

last night i but a z32 ecu on my r33 gtst, i followed these instructions.

R33 pin 19 to Z32 pin 34

R33 pin 105 to Z32 pin 110

R33 pin 110 to Z32 pin 105

R33 pin 112 to Z32 pin 114

R33 pin 114 to Z32 pin 112

R33 pin 57: cut

Z32 pins 29+55 :<<<i had no wire in 55 so i made one.

Z32 pin 33 cut (exhaust temp light)

i have installed a romavale eprom in the z32 ecu and installed a z32 base map with r33 map inside given to me by nistune.

the car strikes up but its very lumpy and pumping in huge amounts of fuel. i checked my wiring and i cant see anything wrong

i even burnt another eprom and its still the same?

even if i remove the afm the car is just the same and i have a z32 afm and r33 .

any help would be great guys thank you

wtf did you put that in for??? why dont you just buy an aftermarket engine management system like normal people do?

Seeing as you aren't just installing a direct replacement ecu, i'd put it all back together with the std ECU and AFM, and give it to a professional.

But if you're hard headed like me, and wont give up that easily;

re-check all your wiring, and make sure all the connections have been properly made.

This caught me out when i replaced my ecu- there was loosely spliced wiring from gadgets installed by a previous owner - and i accidentally disconnected one of the wires without noticing, which caused similar engine behaviour to what you are having.

Check your afm + its wiring, make sure that has been connected properly also.

Make sure the ecu loom is plugged in firmly too - do the bolt up as much as you can. If you dont do it up tightly, the loom can move slighty, and the engine will splutter and shut itself off.

Because Nistune is better than any after market ECU within its price range(Actually quadruple the price range?) And trust me a lot of normal people chip the stock ECU

Now for something helpfull. What AFM are you using and what injectors? Was the chip you put in setup for z32 equipment as far as the K Value? (In other words is the tune expecting a Z32 AFM to be connected and different sized injectors?)
