Im shooting for 650whp but it will be mostly street driven between 350-400whp. I was orginally thinking about using the s300 since I had the s200 before, but now I really don't know. Now im leaning towards Neptune RTP or AEM. What should I get? Thanks. Let me know if I left out anything.

 

Either of those choices can work, it really depends upon what your tuner feels the most comfortable with. Whatever you decide, make sure it can support the voltage reading of a 4 bar sensor.

 

Ectuneeeee ftwwwwwwww

 

The neptune RTP has been discontinued..

I'd go with the S300, I've tuned a lot of 600-950+hp cars with the S300..

 

For your goals Hondata s300 would be my choice.

 

I use the AEM 1030 myself, but my shop has just picked up the PRO EFI setup wich maybe the way I may go.

 

Which one has the most options? Two-step, boost by gear, etc.

 

Hondata S300. Don't worry about the boost by gear so much. Hell, if I wanted the world in a managment system, I'd do Autronic or Motec.

 

AEM EMS is what I personally use, and what I would recommend if you are going to take advantage of the additional features it offers over the s300. I tune and sell the s300 the most for b/h/d series engines anymore.

 

I didn't know that neptune had been discontinued. Im going to first check with my tuner and see what he feels comfortable tuning.

 

I use AEM 1020 since 2000 and no problem just keep up dates and easy to tune with your self, by street tune or dyno. s300 u have to go with your guy to tune it and pay them or wat not. got a lot off options good luck man

 

Jeff, you use to hate aem. LOL

 

Well no one talks good about neptune so far.

 

CROME w/ freelog

 

Neptune isn't bad, its just that the RTP was discontinued.. I don't know what the hell Pro EFI is, and it's obviously something that isn't used on Honda's much..

I'm an idiot, and I like the S300. It's easy to use, and works for me.

 

s300 for me i like it for 600 bucks or so with all the features it has

does anyone know why they discontinue the neptune rtp?

 

ectune is GREAT

 

AEM if you have the $$$...i know a few people who use it and love it. lets them do pretty much everything

 

I had the s200b which I like very much. I know the s300 would be better, just trying to see what else is out there. I searched, new stuff always comes up. I also would like to know why they discontinued neptune rtp.

 

I mean since you asked http://www.proefi.com/ there ya go. My local shop just attending there buy in training, and will be running it real soon on there pro-am civic so more to come on that

 

PM HRTuning if you want that answered, he's the main guy for Neptune here.

If you're going to run a C.O.P. setup, a Tony1 hall-sensor trigger setup, etc, bend over and go with AEM. Otherwise eCtune is the best priced EMS right now. For $399 you can get the license+ostrich+hulog combo for real-time programming, gear-based EBC like S300, secondary maps, 3 general purpose outputs, 2 inputs, etc. Almost everything can be adjusted on it, and almost every month there is an update to fix any bugs that are found.
