hi i wasnt really sure where to post this but there are alot of topics on ecu's in here so i hope its ok.

i have an r34gtr and had a look at my ecu and found this:

was wondering if anyone could shed some more light on this eg. if its tuneable here and stuff like that.

thanks.

scott.

Its funny, you guys think they are worth nothing yet some people are paying big bucks to import them for newer VQ powered cars, mainly as there are no other options. These ecu's sell for 2k new so there must be a lot of r+d in them unfortunately the fuel is different and the map cant be changed over here. The minute a remap is released for my car, these will be worth nothing again as you say.

Probably because Nismo think it's the same as Euro stuff :down:

Sadly the software/part's doesnt cost anywhere near as much as the Bosch ECU gear (like in Audi/VW Gti's etc), so i cannot see how they are justifying a $1500 flash tune.

I can understand the Euro stuff given the software & codes/license costs big $$...

So doesnt neccesarily mean there is a lot of R&D within the tunes in my book.

yeah it would just be a remap of the std maps to suit fuel, boost up and speed cut removal most likely

its better than the std ECU by far but once you do other mods its time to retune anyway

so whilst your on stock turbos and a bit of a boost up its probably fine

there might be some more midrange / max power gains by a full standalone tune however

do a bit of research before you go flogging it scotty... i searched for about 2 mins and have seen a couple of people that said that map is 100 ron

the sticker on the ecu does say to use premium fuel only. it seems to be running fine on bp ultimate though, but ill try and take it a bit more easy until i go to my mechanics.

ok no probs, the boost restrictor was removed so it runs over 1 bar which other r34 gtr owners said is normal so thats good. maybe the previous owner got nismo turbo's installed as well lol.

doesnt make sense if you think about it

if you have a 34R with aftermarket turbos why would you sell it at the base model price

surely you would jack the price up higher referencing the aftermarket turbochagers etc

i got it in a jap auction with the help of iron chef imports. he knew i was looking for a r34 gtr and he sent me an email with this one that one of his guys got at auction over there and asked if i was interested. so of course i said yes. it probably doesnt have aftermarket turbo's but i can still wish lol.

Best bet is to go to your local nistune guy and suck the timing and fuelling settings out to analyse it, i have had some come in that are PERFECT ie i have charged for a dyno run only as they were so good it was a rort to charge for a tune.

Other times they are rich and advanced too much.

PS its not tunable, once off unfortunately.

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
