Sounds like fund-raising bullshit to me. They don't have differing sensors. Check out a circuit diagram.

I ran my old R34 n/a on the GTT ECU...the only issues were TCS sensors and the like, R33's don't have all the extra bullshit and can just be swapped over.

yeh i've turboed my na, and having a few teathing issues, my air flow metre shat its self as they are different between the models, and the ecu is really struggling just keeps leaning out the car even with a safc, my cheapest option is if i can just swap to a turbo ecu n use the safc to tune there but if i have to change the wiring which 3 reputable places that say they have done it before say u have to its not going to be cheaper than say going to dr drift and getting the ecu moddifyed or getting a second hand microtech and hard wiring it then tunning it

Do you mind if I ask why your swaping a NA to Turbo ECU?

My last car was N/A + turbo...put the turbo ECU in to make things easier...isn't so with the R34's too much missing bullshit throws up the "check engine light"

R33's use all the same sensors, they have the luxury of no Turbo pressure sensor, TCS, Secondary throttle motors etc etc

The AFM's are the same between turbo and N/A just different between series 1 and series 2's

I just fitted a emanage ultimate for a guy who turboed his NA R34 and the pins were the same. Rpm didnt work though, no biggy i just used the cas signal. This might be what bought on 666DAN engine light??

so i cant imagine why NA 33 would be differrent.

RPM should work, my one did on the e-manage blue, I can't see them changing it for the ultimate??

No, there is a lot to the R34 ECU's which cause the engine light, I know them backwards unfortunately/fortunately :laugh:

i have fitted probaly 20 or so to R33 and about 6 to R34 gtt with Zero issues. The R34 NA one did not like the rpm signal though (it read 5340 at idle :laugh: ) so i swapped it to cas sens and it was sweet. I probaly should have investigated the rpm wierdness but it was not needed.

Interesting, it must be something the ultimate doesn't like. I wonder what the difference to the blue is???

I know for the 350Z you require the rpm signal adapter, maybe it was a late model using a different CAS?

yeah late R33 seies two and R34 require the internal ignition signal adapter and jumpe 8 set to 12v instead of 5v.

      What brakes on R34 GTT(Europe)

      I would just put EBC back on the "I would not use their stuff" pile and move on.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
