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

hey been searching everywhere for a pinnout diagrame for an na r33 ecu anyone know where i can find one only found the turbo one and it doesnt help when i want to do a comparison

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

the reckers i got my air flow meter from said they are different, the sensor is slightly diff or something and the barcode/part numbers are different, nothing that i could tell the diff between thou

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.

      And make sure the belts are tightened appropriately too.

      They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.
