We tuned the car, then a few days later ran it up again and the AF curve was the same shape, but from say 12.5:1 average to 13.5:1, we were puzzled with what was going on, stuffed around a bit and cleared the computer and went back to normal, so not sure what it was "self learning" or if it can really do that but something was a bit weired. We asked pete about it and he said he never seen it before and few other people said the same, but i don't know how many people bring it back to redyno it to check. Mind you seems to be fine again now?

I have seen this on one specific ECU where it would carry the LTFT data through to open loop - real pain in the arse. There is another PID than just AF learning I think it is AF correction and the only scan tool I've seen that can pick it up is the Nissan version of MDM100.

Also how is it doing boost control in a BNR32 ECU is it a single row of DC?? I have used the std boost control throught the s14 ECU but didn't know it was possible in the BRN32 ECU - but I've never really looked for it.

what about using a z32 ecu, have you played with this option yet, if you can get it to work in sure a lot of 33 owners would be interested.

if your on a budget and dont mind compromise i am happy to do the Z32 and R32 ecu's into R33 but PFC is a better option (IN r33 rb25det).

anyone?

All I can think of, is i've been led to beleive the R33 GTR makes more torque than the R32 GTR because of the ecu, so by going with the R32 ecu, you'll be working with the R32 basetune instead of the R33 one.

Why R32 ecu? From what I understand they have issues with the TPS sensor, cannot control the NVICS system and contrary to popular belief are not straight plug in ( need to switch inj 4 & 6).

There are advantages I can see going this way is that you get to use both knock sensors and exhaust temp sensor.

Much better alternative is the Z32 ecu imo.

interested in the nistune for my r33, so what is the compromise by using the r32 ecu? how much it it to go this way

Additional wiring is needed for an RB20 TPS for improved driveability, idle control, return to idle, etc, and a cheap VCT such as Buddy Club VCT controller etc can be used for the cam timing control, but it can be done to provide a reasonably good result. The best option is a remap of the R33 ECU - Nistune software can be used with an emulator, but not the functionality of Nistune boards in terms of simply pluggling the cable in and away you go, data is still required to be put onto an eprom when done. Any other real time emulation for 256k eproms can be used once the RB25 ECU is modified. Unfortuantely, when the dollar was still strong the RB25 boards were expensive, even more so now... But still cheaper option than trying to spurce a R33 GTST Power FC which are usually priced according to their construction of unobtainium.

R34 gtt and R33 gtst plugs are about the same as cats and dogs unfortunately.

Maybe an adaption harness could be made up :( .......

hey guys, read through all the threads, I have an R33 and like everyone else I'm keen on the NIStune setup. I see you can use teh Z32 ecu's and have them chipped, other than the cost of the set up, whats the compromise going with the Z32 configuration? (Yes I know you have to redo the wiring slightly) but performance wise? configuration?

Cheers,

Matt

But have they got it working with the stock boost control solenoid? I know they got it to work with an S15 but last time I spoke to Pete he said they hadn't worked it out yet for R32 GTR.

Trent have you got any updates from Matt or Pete? I might have to give Pete a buzz now hahaha!

Im not certain, although it is in theory possible if you reconfigure the vacuum hose layout, and fit needed restrictors, although without a map sensor, i cant see there being accurate closed loop boost control, as different airflows make different boost with different Intake temps.

This might be slightly off-topic, but I'm curious if anyone knows how nistune compares to one of its rivals - bikirom. It seems to have additional options like boost control (with a solenoid addon) and generally seems like a pretty mature product.

How do nistune and bikirom compare generally, how do they compare for usability and tunability - are they tuned in the same way?

Right now i'm trying to toss up between these two options, and I can't find any real direct comparisons. Another frustration is it seems as though the major workshops are doing nistune remaps/tuning, but nobody specifically mentions bikirom, so I'm trying to get some ideas if someone who can do one can do the other ...

Any help / thoughts / ideas are appreciated :)

    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
    • My experience with Rising Sun Exports Before agreeing to the sale I tried to do as much research as I could (obviously), his Facebook reviews are 98% and he goes Live at least once or twice a week. I contacted 2 people in the UK who had used him for their imports, both had positive feedback. His explanation and talk through of the import process was thorough, answering any query no matter how stupid it was. It felt as soon as the money was sent, communication dropped off. I asked for shipping updates every 2 weeks or so, not wanting to pester him, he never had any updates. I wasn't informed the car had been dropped off at the port, I only found out by his Facebook story. I asked for the photos taken at the port, knowing he would need some for insurance purposes. I received a few 5 second clips and that's it. When asked again, he said his staff had them. Weeks later I asked again, he tells me he doesn't have any, but does have 50 photos from the original advert. I never received them. I eventually got the documents sent via WhatsApp after I mentioned the port was requesting them. I purchased a CarVX report, to find out the vehicle is a Grade R with recorded accident damage, first recorded in 2017 when it was first auctioned. He never told me the grade, then again I didn't ask. His response was "Grade R means nothing, it wasn't chassis damage". Still, I would have liked to have been informed about it. Jon prides himself on being open and honest when it comes to inspecting cars, it's his main job doing so at the auctions for customers. When the vehicle arrived in the UK I noticed a few little cosmetic issues. It's a 21 year old car so it wasn't going to be mint condition. The side skirts are cracked on each corner and the sealant is failing. The front grill on the bonnet/hood isn't secured very well, mounting studs are missing. Both minor things, but again, it would have been nice to be told. During a Facebook Live walk around video of the vehicle, he mentioned it has a front Whiteline anti roll bar/sway bar. While on the inspection ramp, I noticed the stock item has been installed. When first questioned, his response was "the ARB? Switched? Since when, it never had them". Since sending video and photo evidence I've not received a response. I'm probably being over critical of the overall condition of an old car, but all I wanted was honesty (which he claims to have). I'm aware I wasn't his only customer, he's busy doing XYZ but other reviews praise him for great communication with regular updates and photos, I felt I didn't receive the same treatment. 
    • I was able to get some underside photos while the car was on the ramp The suspension is all Altezza/IS200/IS300 so getting part's will hopefully be less of a headache
