Ok,

I have recently moved to spain with my R32 GTR and i have just recently finished building the engine with a spec as follows

standard head
greddy 272-9.1 cams
ajustable cam pulleys
forged piston and rods
R33 crank
acl race bearings
tomei oil pump
tomei oil orifice
n1 water pump
all hks gaskets
600cc injectors
nismo FPR
nismo flow meters
arc air box
power fc
hks dump pipes
hks super dragger exhaust
trust link pipe
abbey decat

now these are the problems im having

with standard injectors, FPR and flow meters, after doing the idle learning process it has a hunt at idle from about 1000 to 1500 RPM and i cant seem to stop it, if i richen up the whole map it seems to get better but i end up with AFR's of about 11.2, far to rich at idle, its very difficult to map it because of this hunt

if i swop to the nismo flow meters it will not idle no matter what setting i put the flow meters to on the hand controller, the only way it will idle is if i again richen up the whole rev range but it will not hunt if i use these flow meters

at the moment i have the 600cc injectors fitted and the nismo FPR but still with standrad flow meters and this seems to work the best so far but i still have the hunt at idle and its making it almost impossible to map

the problem im having is i now live in the south of spain and there is nowhere that can map it, the power fc is very difficult to map through the hand controller and i need a solution asap

I was thinking of buying an omex 710 ecu, its map based and they will put a base map on it for me plus they will make a loom that suits the car, its also alot easier to map and i could get it mapped out here, i could also sell the nismo flow meters and the power FC and get most of my money back

or the other option was to see if i could get a plug and play ecu like mines or something, that way i can just fit and forget the only probelm here is i want around 500 bhp, is there an ecu that can do this??

let me know your opinions and if you could let me know what flow meter setting everyone selects when they go to nismo flow meters

Cheers

Ricky
