Hey Guys, get this! I have had my 2nd 33 for about 8 months now and no amount of replacing sensors or tweeking things on the dyno would make it run smoothly. It has the usual 200rwkW mods, full exhaust, boost controller, fmic, pod, etc...but I could not for the life of me make out why it would surge, idle eratically and generally run like a pig. That is until I decided to swap ECU's wih my house mate with an identical car. As I removed my ECU I noticed a sticker on the side of it that read "Nissan Genuine Remanufactured" What the f#*K???

Am I to believe that this is a 2nd hand computer repaired or maybe a warranty job?? Anyone ever heard of such a thing?

BTW with the new ECU my car performs brilliantly.....just sucks that my mate wants his ECU back...

it most likely has a chip in it. many, many ecu's are used by tuning companies to put their chips into. they use remanufactured ecu's hence the sticker. it's no big deal. very common.

For all intents and purposes it looks like a genuine nissan sticker, is there anyway of identifying what has been changed, if anything, maybe with a scan tool?? Also I have disconnected my VCT, and now have what feels to be a much more linear torque curve...are there any down sides to doing this as I understand that Nissan wouldnt have put it there for no reason.

VCT helps with down low power kind of like a powerband

I have the exact same sticker. And my car has always run kinda rough. Like jerky on boost. I just blamed the coils and ignored it.

However yesterday my ECU shat itself, so I have the opportunity for a new one.

Only thing is, I have no idea weather my car is a series 1, 1.5, 2 or what. lol. It's the most hybrid R33 you'll find. It's even got GTR parts lol.

So here's the story, its a series 1.5 I beleive, made in DEC 95. Has S2 spoiler n stuff like that. Airbags etc. Just stuff series 1's don't. But what's confused me is that there is no igniter box in the engine bay, so this means it's runnin series 2 coils yes? So does that mean its been converted, or it was made with a S2 drivetrain?

Basically, I need to know whether I should order a S1 or S2 stand alone aftermarket ecu or are the ECU's the same?

Cheers, Jack

thats normal of a series 1.5. no igniter pack. they're basically s2 engines in s1 bodies.

Sounds like you have found your problem BlueGTS, thats exactly what mine was doing. I'd be keen to know why they were remanufactured in the 1st place, and if so how they came to be in our cars.....jus so I can find the guy that did it and choke him! :)

they dont have the second air bag, they dont have the plastic compressor wheel like the series 2 have so they have the series 1 turbo and they use series 2 coils.

mine is a 95 series 1.5 as well

Thanks heaps for the replies fellas.

So does that mean I want to buy a S2 computer then?

Only problem is, my mate came over last night in his S2 R33..... and...... his setup is different again! He has an 8-pin and a 2-pin plug just before the coils loom. However it appears that at the end of the 2-pin plug, there is just a small plastic box with the symbol on it discribing it as a small capacitor? From memory it was 0.47uf. There is a black and white cable going to this, so I can't work that out!!

I only have an 8-pin plug to the coil loom.

If anybody in SA has a spare S2 ecu and 2 S2 coilpacks they can trial in my car it would be very greatly appriciated!

Not far from marion, don't wanna openly say the suburb on a forum because of my cars safety lol. But yeah I'd be keen as to try that. Only prob is I need two coil packs now as well though.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      sold listed as a Tomei LSD 1.5 Way For 1998+ Nissan Skyline ER34 25GT RB25DE w/Open R200 https://www.ebay.com/itm/174006114594?campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=&mkrid=711-53200-19255-0&loc_physical_ms=108689&loc_interest_ms=&campid=5338967980&mkevt=1&mkcid=1&toolid=10050&customid=71883f2ccc571356e0a757bc7adfdde2&mkrid=710-53481-19255-0&loc_physical_ms=108689&loc_interest_ms= it went in like butter all gears, alignment, back lash etc, rotation and clearances correct, and if rolling all rotates smooth and free when coasting down road , clutch in or out over 10 mph smooth... its the binding, clunking and jerking from a stop that is most concerning, also seems like its going to tear the tires off in 10 miles of normal road driving.

      What 1.5 way? There's no such thing really as a 1.5 way, just different ways of explaining 2 ways with different ramp rates. HOWEVER. In any driving in a straight line your 1.5 or 2 or 1.7 way should have no clunking at all. With the clutch fully depressed the diff should be silent (unless it's welded but I'm assuming it's not). Something aint right here.

      Clutch is a spec brand, new clutch system,( PP, flywheel, friction disc, etc. pull type) installed 100 miles ago, with no problems.

      new 1.5 LSD issues/concerns

      By JC71 · Posted

      looking for some help and maybe some insight on others experience with a new LSD. R34 GT ran and drove beautifully, but always alot of grip loss due to the open R200 rear end, so I just installed a new 1.5 LSD way into the stock open R200 for a ER34. Simple. Everything seemed right. I test drove for the first time this weekend. as I started to back out the garage the first time slowly with tires straight it sounded and felt like I had a loose or half disconnected drive shaft...that was clucking around loose and shaking entire vehicle, and making it feel like the trans clutch was spontaneously slipping then grabbing very roughly while just letting out pedal slowly. I backed it out went to pull forward with the same noise, shake and slip grab feeling with hesitation, I turned the tires to back out more and then pulled ahead some same thing but worst because of added wheel resistance (which that I expected) puzzled … pulling it back in checking everything over and finding nothing wrong, I tried it the next day. same thing, couldn’t believe how it shook everything again making a terrible noise and making it feel like the trans clutch was slipping and grabbing, but I got it out of garage into the driveway, got it straight, drove forward and then reveres a few times in a straight line everything shaking , causing what felt like clutch slip and grab every time, sounded like right behind front driver tire and I could feel it in the floor board with my feet,... worst right when beginning to let clutch pedal out to engage slightly, shuttering and sounding terrible along the way…I managed to slowly get down the road, babying it the whole way, once I was rolling (out of 1st) seemed to be better and between shifts, then clutch felt closer to normal…not slip/ grab etc., but back down to any stop, straight road or turning, same thing. Made no difference if all tires were straight or if I was turning. All other gauge read out correct. with in 2 miles as planned I reached the empty parking lot and performed the break in procedure that came with lsd, essentially to drive in a figure 8 a bunch.  Did this, binding chattering, and shaking the car the whole way. I drove it back home seemed somewhat normal once I was in straight line and past 10 mph or so, and I know it will “bind” on corners and cause some tires squeal when turning especially from a stop, but when I begin to move it still causes what feels like the trans clutch to slip and jerk badly as well as shaking the entire car, and sounds terrible, that I didn’t expect. I used the fluid they supplied with LSD kit and did the breaking, planning to change fluid as they suggest after breaking, but wondering will it get smoother or less aggressive with use? maybe a 1.5 is just too aggressive for normal road driving?   I have a LSD that I put in my 71 cuda when I restored it, with amazing smooth , quite yet effective results. Different style LSD but that ones a joy to drive. maybe expecting too much from this R200?
