Figured as much...I don't know much about ECU solutions other than there is nothing good for AP1's on a budget. KPro, EManage etc are all hard to justify. Its either V-AFC or finding a spoon/mugen ECU which are overpriced and no guarantee there. I know the megasquirt guys posted up about possibly working on a solution, didn't they?

Sorry, I wasn't talking used. I should also clarify on the tuning complexity aspect as well - some PnP/standlones require more hand holding than others. This takes away from the install it and forget it aspect of things. I know of instances where people go to piggyback and standalones to have lots of annoying headaches and maintainence work. Guess, it just comes with the territory.

He's saying he can make it a piggyback solution.
Interesting...

Megasquirt was originally a DIY fueling controller, designed to allow people to convert their carbureted vehicles to EFI. It has since grown into much more than that and has quite the capabilities list these days. The Megasquirt3 Extra can handle sequential fuel, individual COP, realtime barometric feedback, and tons of other features. They have been advertised as standalone ECUs for quite a while. However, they could be used in a piggyback sense...but not exactly like the EMU. There would be no actual piggybacking of fuel or timing signals. The Megasquirt would generate it's own fuel and timing data and not use the stock ECU signals. I've built a MS2-Extra in the past, but sold the car before installing/tuning with it. I can communicate with it via my laptop and use an emulator board to look at the output signals, but that's all I've done with it. The code is open source and the application range is huge...finding tuner support can be challenging, if you're not interested in learning it yourself.
The recent info about S2000 crank/cam signal support, COP support, and sequential fueling has definitely made me reconsider some of the previous STR-related discussions about what would be a legal solution. I'd like to bring this topic back to life, if anyone else has thought about it in more detail...
As a community, it's on us to determine what's STR legal and what isn't. The rules are so vaguely written that you could technically use just about anything. The STAC hasn't shown much interest in clarifying the rule set or releasing any statements about what would be deemed legal and illegal. I was originally quite conservative with what I thought was STR legal, but my stance is slowly shifting towards more liberal allowances.
If we can maintain OBD2 port functionality, refrain from generating CELs and let the stock ECU handle some of the tasks, e.g., radiator fan activation, alternator control, dash cluster functions, etc., would it be legal to use a secondary ECU (Megasquirt, for example) to control the fuel and timing outputs? Granted, some of that would not be very easy to achieve...like no CELs.

They posted about whether the community would be interested in one of their DIY PnP solutions. This would NOT be STR legal. However, the interesting takeaway from that thread is that they have added the RC51 (Honda sport bike, I think) crank/cam signal processing to their latest firmware. They're of the opinion this crank/cam signal support will also work with the S2000.

They guy that tuned my VAFCII feels very confident that he could make the Haltech work and be STR legal. I just could not bring myself to buy a 3rd option that may or may not work. The things he said he could do with that unit was very compelling. However, when it comes to spending $, I am very risk adverse.

Anyone want to propose allowing standlone ECUs to the SEB again this year? I'm curious if there are any ST competitors out there that don't want to see standalones become an option since it seems that lots of people are already jumping through hoops and spending even more money just to get by with a piggy back rule which I feel is an outdated view of ECU tuning to artificially control costs. Let's face it, piggy backs are in no way cheaper to standlone units today and if they use emissions as a reason then we're already in that grey area by allowing high flow cats in the first place.
