Hondata is considering adapting the new RSX ecu for use with our S2K. Because it is already flash programmable, it cuts down on some issues with development time, etc. RSX ecus only cost $550 new from Honda, so for that price, plus a few $$ more, Hondata could give you full functionality and a bolt in package. Of course, these things take time.

Thats what I was hoping to hear someday. I communicated with Hondata several months ago about the S2000, and they mentioned they were experimenting with the ECM, glad to see they came up with a solution, which sounds like fell into their laps with the RSX thing.

Very cool, maybe Honda did that on purpose?

with new management you could turn up the wick of your supercharger AND have even better drivability and so on, hey I'll have one eventually for my S2000. A good programable one is adaptable to just about anything you can do to an engine, but the tuning is custom and time consuming, then again if its tuned well you wont have to mess with it much.

 

A few notes:

- Expensive, expect to spend no less than $3k on the management and other misc expenses (like sensors, VTEC switch, etc.). There are a lot of hidden costs here.
- Time. As mentioned, expect to spend a few hours just to get it to run, then probably at least a full weekend to get it to run well enough to drive. Expect to spent at least another weekend or more to get it to run well, and even more to get it to run better than stock.
- Installation: I'd guess at least a weekend of farting around with mounting and wiring, possibly more. You'll have to completely butcher the stock wiring and maybe even relocate it (depending on size and shape). Most units require new sensors (TPS, MAP, crank angle) from GM or Bosch, so expect to spend some time fabbing those items to work.

To answer another question, a box like the Link or Unichip (why in the hell would you want them?) are no different than the V-AFC in my understanding. I would say stick with the AFC, it's more tried and true and in my opinion is a better product with better support.

UL: Are you sure that the RSX box has a flash processor? My understanding is that it does not, but Hondata was hoping to find a flash processor for it. I spoke with Doug at length about this, I think I may have an "in" with Oki (talked to a new sales rep yesterday). Hondata would certainly be the way to go, they know Hondas better than anyone and inherently use Honda sensors, wiring, and support VTEC. In my opinion, it's the ONLY system out there for any Honda.

I'm surprised that Hondata or anyone else hasn't figured out how to use an older OBD ECU to drive the F20. I would think it would only be a matter of programming it to get it to run- you may sacrifice an engine or two, but isn't that what R&D capital is for?

 

Marcucci, I'm disagreeing with your first 2 paragraphs. You are referring to the first installer - the guinea pig so to speak. Once a kit is made, the install time will drop dramatically.

Also, the Subaru guys, for example, have premade baselines available for them. You're running a turbo with these injectors on this size motor: here's a map you can download into the TEC II to get you there.

So, if one were to offer a package such as a TEC II for the Comptech supercharger, the install and tuning time would be very short. You can install a TEC II kit and be up and running in under 3 hours now.

Of course, the Hondata way, if it works out, will be sufficient for 99% of us on the board, and even easier. I hope something comes of it.

 

Can anyone here get the software to program the Fcon V? If so this would be as simple as having a hybrid harness made, then plugging it in, while using the same sensors, but having full programability. I am interested if anyone can do this.

Wow this is the thread i was looking for. I don't know any of the terminology you guys are using. Some of it starts to make sense then i get lost again. I would like to understand because i think what you're talking about may improve drivability with the option to race without having to install many many overpriced aftermartket parts. If you could explain the basic's of what youre discussing it would be appriciated. Thanks Mike

 

What about the new AEM EMS does anyone have any info on this?? They have a application that fits the S2000 stock wiring harness, and it has the ability to read boost, and fully program fuel and spark delivery...also ive seen it advertised for $1400 so its somewhat affordable for the features it gives you
