Will An R33 S1 Auto Ecu Run Manual

[rnbguy]

will an r33 s1 auto ecu run a manual r33 s1?

[R31Nismoid]

yes

Yes it will - But I remember reading somewhere.....

That the ECU looks for a change in the auto box and increases the AF ratio because it thinks that the box is still sitting in first, thus making the car use a lot of fuel.

I may be wrong about the above statement, but I have used an auto ECU before in an emergency with no ill effects on a 32.

auto's can use manual ecu's. only difference is the timing retard before the gears change - which on a performance car isn't desirable anyway.

my car is auto and ive used a mines chipped ecu off a manual and it ran 100x better than i could imagine.

thanx for the replies, the car its going on is a manual r33, the ecu is comming frmo an auto r33.

ran a auto ecu in my r33 for a couple of years after a conversion. would sometimes rev a little (about 1000rpm) on idle and power curve wasnt nice. put a manual ecu in and idle is good now and much smoother power curve. first pic is auto ecu on standard turbo, second is manual ecu on highflow turbo. both using safc2

nice post, okay ill see how i go and post my results here... however im hoping the ecu doesnt panic because some wire would be missing or something with a manual ecu loom plugged into it.

i wasnt sure if i should start a new thread or try here first, but my mate wanted to know if he can use a r32 gtst ecu to run his r32 gtr (putting a new eprom in it ofcoarse)

you can use an auto ecu, but why bother? just get the correct ECU

also be sure to note, the auto ECU, will be checking if the car is in PARK from the gearbox

so dont be suprised if it doesnt start, youll have to find which signal wire it uses for this

[rnbguy]

i just scored a free auto ecu for my manual r33, mines tunned etc... so susing out if i can use it, very nice tip paul i'll keep that in mind

[paulr33]

throw the mines tuned ecu in the bin

[rnbguy]

lol now youve lost creditability, writting off someones work without seing its results is very amature.... i'll give it a go monitor it and then judge.

the reason why I dont think Paul would like the mines ECU is because it didnt cost $1500 and come from Apexi.

I was using a mines ecu for around 9 months and for the price you're paying they are quite good. only down side is you're limited to the mods you can do to your car while using one - and that there is no rev limit. AFR's on mine on an rb25, custom GCG hiflow, cooler, exhaust bla bla bla were between 12.1 to 11.5 on 15psi, any more boost than that and it would get too lean.
