Taco Bandit Posted May 5, 2018 Report Share Posted May 5, 2018 So, a little bit of a back story, I had a S1 RB25 and then it's ringlands blew. Everything for my swap is made for a RB25 S1, I just recently swapped in a RB25 NEO and now I am getting ready to fire her up. With that being said I should not have any problem running my Link ECU on my RB25 just as long as I load a RB25 NEO base map, correct? All the wiring to my new motor is connected the same way and the only thing that is changed is the motor itself. I am using my old wiring harness so my Link ECU is going to plug in just fine. Any questions, comments and of the like are welcome! Thank you in advance! Quote Link to comment Share on other sites More sharing options...
ClintBHP Posted May 5, 2018 Report Share Posted May 5, 2018 Should be no need to change maps if the vehicle is the same. Do a complete system check before you run, so check every sensor and actuator works. The only thing that may need wiring is the second air temp sensor.

Taco Bandit Posted May 5, 2018 Author Report Share Posted May 5, 2018 Sounds good. I was never able to get my last RB25 tuned with the LINK because while I was waiting for the ECU it started getting real bad blowby. Thank you! I just wanted to make sure that my logic was correct. I am going to be road tuning this with the help of my friend so this is going to be a great learning experience. Quote Link to comment Share on other sites More sharing options...
rrob Posted May 6, 2018 Report Share Posted May 6, 2018 The CAS wiring will need reversing as the pinout is opposite. Also NEO's dont take the timing others do, so be careful. Quote Link to comment Share on other sites More sharing options...
Taco Bandit Posted May 6, 2018 Author Report Share Posted May 6, 2018 Would I be okay with using the my old rb25 CAS? Do you mind going more in detail about the timing issue? Are you basically saying that when tuning the NEO timing on it is different from non neos? Quote Link to comment Share on other sites More sharing options...
LoveBoost Posted May 7, 2018 Report Share Posted May 7, 2018 The CAS drive on the cam is different and does not allow the old CAS to be used. The Neo has a higher compression ratio Quote Link to comment Share on other sites More sharing options...
