everyone is telling me to get a nistune done on my 33, i know that its a computer upgrade to your standard ecu, and it unlocks more potential. what potential is that? do i need to change engine components or will it run on a stock standard engine? and most importantly is it a plug and play or do i need to take the car to a dyno to have it tuned like i would for an aftermarket ecu? any info would help. oh and how much does it cost to get done?

It's a piggyback board that is put onto your standard ecu, It's fully tunable and yes you will need to go to a dyno to get it done. Most places will charge around the $600 for an initial tune. Yes it will run on a stock standard engine.

cheers thanks for that.

My question is, why do you feel you need to change to a programmable computer? Are chasing more power?

But yes, NIStune all the way as far as i'm concerned if you dont need all the extra features of an ECU such as a Haltech, Link, Microtech, Megasquirt etc.

WARNING.

You cannot put a Nistune board into your R33 ECU. If you want to Nistune your car, you will need to get either an R32 ECU or a Z32 ECU and do that. There are differences between them. The R32 does not control your inlet cam. You will need to get a window switch of some sort to re-enable VTC on the inlet cam if you use one. The Z32 ECU, on the other hand, does control VTC, so makes that easier, but there are some other hassles with using a Z32 ECU on a 25. Your best bet is to google and read up the very many threads on this and other forums on these topics.

The main reason to put Nistune onto an R33 is to allow you to turn the boost up to 12psi (about the limit for standard turbo) and then tune out all the extra fuel that the standard tune puts in at that sort of inlet flow, and also to wind some timing back into it. The stock tune is horribly conservative. You will make more power and use less fuel.

Oh, the other reason to go Nistune over any other programmable ECU option is that to pretty much any cop it looks just like a factory ECU and they would actually have to open the ECU up and look inside to see that it has been modified. Pretty close to the only defect free ECU option available.

that was exremely usefull thank u. ya i am chasing more power, but from what ive been told my standard ecu is shitting itself. im replacing the engine as the engine has lost compression, and my friend is buying it off me. the problem then lies that if i put a new engine in, the ecu is going to give me shit. its overfueling on standard boost and at 12psi, im regestering all 12psi so there is no boost leak but it feels like im not hitting boost at all, it drives normally, no noises or missfires. but put on a dyno it has 140rwhp. so ive lost about 60-80hp somewhere. i thought it was compression (140psi wet) pritty much even. i know its low but everyone said i still shouldnt lose that much power, as well some one on here told me that the factory computer is set to over fuel itself when dickheads just up the boost without considering the AFR. and aparantly they tend to shit themselves or that specific part of the fuel map. i dont really know im still trying to learn.

Yeh most plug in ECUs can use the stock cover these days. Can do the same with VIPEC, adaptronic etc.

I wouldn't go NIStune with an R33. Personal opinion. As has been said, go read some of the threads about all your choices, there's a gold mine of info here.

What do you guys consider an acceptable quote from a business to supply the nistune chip, mod a z32 ecu to support the nistune and then install and tune for an r33 gtst?

Im guessing i would have to supply the z32 ecu so exclude that from the cost...

      Fender flare widths across front/back of car

      By AdiR34 · Posted

      Hey y'all! I'm curious about how y'all go about widebodying your cars. I noticed that when running a square setup, my front wheels are a bit more tucked in than my rear wheels. Not by much, maybe 5-10mm. This leads me to wonder - when I widebody, should I use narrower front flares and wider rear flares? I found a set of 40mm rear flares that I really like, and was thinking of pairing them with some 18mm front flares, but I don't want the car to look strange. How have others done this? Note, I'm in a sedan. Thanks!

      And if it was anything other than an auto tranny part, it might be a problem. But seeing as all auto trannies belong in the recycling bin, it's fine.

      Stock rb25det neo questions

      By dbm7 · Posted

      All the schemas I can see, indicate your typical setup of ATF 'cooler' (read: heat exchanger) in the bottom radiator tank..ie; https://nissan.epc-data.com/stagea/wgnc34/5413-rb25det/engine/214/ ...but I can prattle on a bit here. These trannies have a thermistor in the sump ~ the TCU reads this and 1. bumps the line pressure up when the ATF is 'cold' and 2. prevents the TC lockup clutch from operating, until the ATF comes up to minimum operating temp (keeps the ATF 'churning' through the TC so it heats up quicker) -- trigger point is around 55C. In these conditions, the engine coolant temperature rises faster than the ATF temperature, and also helps heat the ATF up, which is why it's best to think of the in radiator tank setup as a heat exchanger ; the heat can flow in both directions... ...with these trannies, the 'hot' ATF comes out the front banjo bolt, flows through the cooler/heat exchanger, and returns to the box  via the rear banjo bolt. This gets a mention, due to the wildly different opinions wrt running auto trans fluid coolers ~ do you bypass the in radiator tank altogether, or put the cooler inline with the in radiator tank system...and then, do you put the additional cooler before of after the in radiator tank system?... ....fact is the nominal engine operating temp (roughly 75C), happens to be the ideal temperature for the ATF used in these trannies as well (no surprises there), so for the in radiator tank system to actually 'cool' the ATF, the ATF temp has to be hotter than that...lets say 100C -- you've got 25C of 'excess' heat, (slowly) pumping into the 75C coolant. This part of the equation changes drastically, when you've got 100C ATF flowing through an air cooled radiator ; you can move a lot more excess heat, faster ~ it is possible to cool the ATF 'too much' as it were...(climate matters a lot)... ...in an 'ideal' setup, what you're really trying to control here, is flash heating of the ATF, primarily produced by the TC interface. In a perfect world, wrt auto trans oil cooling, you want a dedicated trans cooler with builtin thermostatic valving - they exist. These should be run inline and before the in radiator tank system ~ when 'cold' the valving bypasses the fin stack, allowing the ATF to flow direct to the in radiator tank heat exchanger, so it works 'as intended' with helping heat the ATF up. When 'hot' (iirc it was 50C threshold), the valving shuts forcing the ATF through the cooler fin stack, and onto the in radiator tank heat exchanger...and you sort of think of it as a 'thermal conditioner' of sorts...ie; if you did cool your ATF down to 65C, the coolant will add a little heat, otherwise it works as intended... ...the 'hot' ATF coming from the front bango bolt, is instantiated from the TC when in use, so all/any flash heated oil, flows to the fluid-to-air cooler first, and because of the greater heat differential, you can get rid of this heat fast. Just how big (BTU/h) this cooler needs to be to effectively dissipate this TC flash heat, is the charm...too many variables to discuss here, but I just wanted to point out the nitty-gritty of automatic trans fluid coolers ~ they're a different beastie to what most ppl think of when considering an 'oil cooler'... /3.5cents
