Hello all I am having neo issues to say the least. Here's the story: bought the new neo off some guy for 250 brand new thinking that since it was newer=better but, so far I have google searched as well as searched on here and other forums and have found either unanswered threads or conflicting answers. So my questions are; I have read that apexi messed up with the wiring diagram and instead of using n3-a I should be using(wire it up) n3-b to tune the redtop. Also what would the base settings be for the sr to run right. I am very confused and dissapointed as this was supposed to be such a great product and my car is not running to full potential because of it. Anyone have experience tuning with it?????

Specs:Sr redtop motorFMIC w/vented BOV255 Walboro pumpBkr7es 11 plugs gapped at .38SOHC MAF (heard that I could use with no problems)Stock sr ecuNeo (that is being a pain)

Thanks in advance

I used N3-a to wire up my NEO like it showed in its manual. Where it tells you to wire the RPM(Green) wire is wrong. It should be Pin #3, which is one box to the right. For basic setup, of course you have to have the car off...but i have mine set @ 4 Cyl, Throttle is up(pointing up) and sensor is set for hotwire, 6in 6out. Hope this helps...

That helps a lot I will be doing this to see if my revs finally read right 2morrow as it is at my stepdads house. And to be sure we are on the same page do you remember what color wire that was that you did wire it to? Thanx!!!!

I do have another question however, how do I set my tps sensor (I know I am supposed to unplug when turning car on then after it idles a while plug it back in-is this what is meant by setting it?). And one last thing on my sr redtop ecu the way to read codes would to be to turn the screw right or left(I read that it was one way or another just don't remeber which).

Thank you again

Just to confirm, you use the "vehicle with hot wire, flap, and pressure sensor right? What are you guys hooking the illumination power (Orange) up to?

Ummm yes, hot wire is for cars with MAFS. The karman sensor is not the right setting for any Nissan.
