Hey guys, ive done my research and ive decided tht nistune is the best way to go for my r33 and the power figues i hav, this way i can still keep all the safety features. so im going with a z32 ecu.

i know it has to b out of a 300zx between 89-95 model, and i know the wires i hav to change. seems easier then it was hooking up my safc2.

the onli question i have is, my car is manual, does that mean the z32 ecu i get has to b a manual, i think i was told it doesnt matter, but can anyone clear this up for my as ive found a cheap auto one :( and i plan to wire it up myself to save some cash. my understanding is if i run the z32 afm with it, ti will run rich, but i will b able to drive it to my tuner

thanks

Adam

Is the tuner going to install the Nistune daughterboard, or will you be driving there with it already installed? In my opinion it's dangerous to drive it to the tuner, unless you've set in the Nistune software to factor into the Z32 AFM. I'm pretty sure it's the other way around, the Z32 AFM without the AFM correction, the engine will run super lean.

Don't hold me to it, but I'm fairly sure auto/manual doesn't matter as you'll be loading the R33 GTS-T basemap into it anyway.

hmm ill have to double check with him, he will be installing the nistune board, but he said its ok aslong as i have both z32 ecu and afm fitted, if i have the stock afm it will lean out.

thanks

Are you sure your tuner is recommending driving to his shop with a Z32 ecu that has a stock basemap to run a V6 of 2l/3l (VG20 or VG30, I don't know 300zx's at all) with a inline 6 2.5l (rb25det)?

take the ecu to the tuner and get him to put the nistune board in it with the basemap required to run an rb25 on a z32 ecu. then take the ecu home and install it.

then you can drive it to him to be tuned.

cheers

as long as you have the z32 afm installed, i'd say it should be fine to drive it to the tuners even with the stock z32 map on it. the reason being that if you are cruising along the o2 sensor is going to be controlling the AFRs to a large extent. the injectors on the z32 are the same size, and for a given amount of air going into the engine the ecu should be putting in the same amount of fuel. it would just be that the rb25 isn't going to use as much of the higher load area of the map due to the lower capacity of the engine.

also i have heard of people on other forums who have been running an untuned z32 ecu in a skyline for a few months with no issues.

    • I would hope so. I worry that it also might depend on whether the person working on the claim has had a good day or not. I could imagine that for example modified brakes would be an easy thing to point to for affecting the outcome of an accident. I don't know. I will keep paying my premium and hope for the best. But at the same time keep safe distances, drive defensively and avoid dickhead P-platers in lifted utes  
    • I was just working on the assumption that a cammed V8 is significantly less polluty than a Japanese I6 turbo was at the way they tested it in an IM240. Perhaps I'm wrong! Perhaps cutting one of the readings I got in half is a tall order. I don't know too many people who actually got their cars emission tested with a RB to really compare the data.
    • I thought it was just if “the modification effected/caused the incident”
    • Ok, good to know. I have open loop I think, I forgot which ones which but I am running the o2 sensor, brand new and I got a new boost solenoid because my last one was faulty and overboosting by a lot, but it's still technically overboosting. Haven't really bothered to hunt it down as I don't send it hard regularly.
    • You should not be able to see much smoke behind you if the mixtures are good - for ~13-14 psi anyway. It's not like you need to be running hell rich for only that much boost/load. Your tune might be a tad too rich. The tuner might have done that because they like to run a lot of timing. It's impossible to know what's going on from here. It won't be the actuator. It won't be the MAP sensor. Regardless of if by "MAP sensor" you mean either the Neo ECU's boost sensor (which is literally only that, a boost sensor so that the ECU knows a) that it's achieving boost, and b) that it is not overboosting) or you mean the dash gauge's MAP sensor (because it can't have any effect at all), or you mean the boost controller's MAP sensor (because it is very unlikely that it is running in closed loop, and so it is effectively just used to know when the pressure goes positive and so you can see the boost on the display, for the most part).
