Off the top of my head for the VG maf's there is : A32 J30 M30 Y32 Z31 e Z31 et Z32 Part number indicates this is a purple sticker M30 maf. It is not the same as z32 maf. Same as found on various rb20 and rb25's.

Only just thought of it but it is probably obvious anyway. If you have an s2 rb25 then you need to run an external ignitor. For anyone wanting to use an r32 ecu then just note that injector outputs 4 and 6 need to be swapped around.

The main problem with these sorts of topics is the original question is not defined clearly enough and then everyone comes up with hypotheticals to suit their argument.

It's one of those things, when you are desperate for an ecu they are hard to find and expensive. They can go for $50 or $300 just as easily. Later when you don't need it, someone will offer one for free.

Dyno run as per request. Sorry it took a while, couldn't remember simons rego. There is definitely more in it. Simons tune is extraordinarily conservative because he thrashes the life out if it and it's on the injector limit. One day when i have more time i'll put it back on the dyno because i'm sure i can get it to spool quicker with some timing adjustments. These turbos seem to come to life at around 16-18 psi.

It does not matter if the ecu is auto or manual. The hardware is the same, only the software is different. So you can use a manual map in an auto ecu and vice versa. What i was saying before though is i haven't seen this ecu swap done on an auto before. I'm not really sure if the z32 ecu would communicate properly with an r33 auto trans. Oh and of course while r32 ecu's are a dime a dozen, it seems to be more tricky to find a z32 ecu for a reasonable price.

Ok so with the wiring for the z32 ecu a bunch of wires are no longer needed so don't stress about them. Z32 ECU REDUNDANT WIRES - ************************** 6 8 33, 34, 35, 36, 37 54, 55 57 102 111 Z32 ECU CHANGED WIRES - ************************ Injector and ignition coil wiring. (double check, triple check, get it right) 19 and 34 need to be swapped over. (power steering switch) R33 KNOCK SENSORS - ******************** The easy way to do it is just hook up only one knock sensor. If you have a cro or multimeter you can rev the engine and check which knock sensor puts out the higher signal, then connect that one to the z32 ecu. Or just use the one closest to the firewall. AUTO TRANS? ************ Dunno, never tried it on an auto. Feel free to have a bash.

One would assume that if they have tapped into an ignition switched power supply then it should not drain the battery. However it does sound a bit suss that the battery started going flat after this wiring had been done. Get someone to double check that it is not hooked up to a direct feed from the battery.

Thats crap mate. I hope ebay does do something about it. Ebay seems to do more harm than good these days. Providing scum with an easy and relatively anonymous way to sell fake, stolen and low quality products.

Definitely only 6-spd manual has the bigger injectors. Check the part number to be sure. Nissan Part No. 16600-91f00 Side feed Terracotta Top Colour Oval Plug Impedence : 11 ohm They do usually flow lower than 480cc when tested as the s15 fuel reg runs a slightly higher rail pressure than s13/s14/r33.

Ok i'll put the r33 and z32 ecu pinouts in here as well.

Ok i can't seem to attach excel files so i had to just take screen grabs.

Sorry, i have been meaning to get back to this thread but i have been very busy lately. The R32 ecu does not have the hardware output to run the vct. You can make an r32 map to run an r33 but you lose vct control. This seems to be a popular topic at the moment so i will get together all the info i have for r33 and put it up here sometime this week.

Bretto - that makes sense now mate. The vct still isn't switching the way it's hooked up, it is just always activated. Tuitahi - Off the top of my head that sounds right to me. Also have to change one other wire, it's for the power steering. A bunch of other wires from the z32 ecu become redundant. I do have all the pinouts, i will put it up today/tonight sometime. Sorry, heaps busy this week. Cheers

He got an r32 ecu to run the vct? I can't see how thats possible, the r32 ecu has no outputs, or software to control it. How did you r34 neo rb25det running on an r32 ecu? What about the coil-pack ignitor and map sensor?

Anyone with a soldering iron, a copy of both the R33 and Z32 ecu pinouts and some common sense should be able to do the wiring. Sam (Dr Drift) or myself could provide you with an eprom to get it running. Not sure who in brisbane could dyno tune the stock ecu in realtime. Well there are external VCT controllers available. I think HKS makes one. Not sure about the vtec thing.

Yeah you can run an r33 rb25 with an r32 rb20 ecu with rb25 maps programmed in but you do lose vct. Using a z32 ecu maintains the vct control but needs some re-wiring to run the engine. Mainly rewiring the injector and coil outputs to suit the different firing order. R33 ecu's are a pain to remap as the memory is stored inside the main processor. These chips can be replaced but they are much more expensive than the common eproms used in r32 ecu's etc. The chips are also one write only so if the tune is not spot on the first time you have to throw away the chip and start again. There are daughterboards available from japan to make the programming slightly easier but they are also expensive. The beauty of remapping most nissan ecu's is that they are relatively easy and cheap to modify. Unfortunately with the r33 there is a lot of extra messing around and time involved which makes it not such good value.

Damn i forgot to do a printout of simons car today. I'll try and do it tomorrow if i remember. Torque and boost. All his runs are from about 1600rpm.

Agreed, it's refreshing to see someone downsize a turbo in search of more response. I'm not 100% sure on specs but i do believe it is simply a smaller exhaust wheel. I will get a printout of boost and torque on monday. Sounds awesome dude. Simons tune was real conservative - 15deg and 11:1 afr @ pk tq - 18deg and 11.5:1 afr @ peak power. Still needs some work i think. Regarding the exhaust cam gear, well that is the same thing i suggested to simon. You can in fact move the peak torque up or down the rpm band. You are getting to the point where a bigger set of timing sticks will work wonders too.

Simon replaced his max oversize RB25 with a standard hi-flow spec. He got it bolted up last night, then we quickly threw it on the dyno this afternoon for a very quick check of the tune. Only had time for 3 runs on the dyno but it did make 223rwkw on 16psi with conservative timing and afr's. It is absolutely maxing out the std injectors so we "modified" the fpr to get a bit higher rail pressure. Needs bigger injectors to go any further. Simon took it drifting tonight and reports that it fries tyres. I'm sure he will fill in more details later.

$150 now. Any interest?

SOLD!

Thats right a sort of browny red colour.

PN : 16600-91f00

Nissan ecu's do have a constant power feed direct from the battery. I think people are grossly overestimating the capabilities of the ecu's self learning.
