I'm currently running the URGE non DBW ITB setup on my AP1 with the AEM EMS V2 and I am very impressed with the driveability. It's a very stock like feel as Gernby said.

I've been running the URGE DBW ITB's on my '08 S2000 for about 18 months. I'm also running a similar setup on my '13 Civic Si. Both are tuned with FlashPro using the new (chambered) URGE MAP block and a MAP based tune. It took a while to get it running well enough to pass the OBDII state inspection, but it now gives a very "stock-like" drive. I switch back and forth between those 2 Hondas for daily driving.
That said, I can't imagine getting an ITB setup to run well with a GEMU and stock ECU.

Great for the guy that is working with URGE. Not so great for the customers waiting on the vaporware.

Anyone lead me in the direction to find a good used set of Toda ITB's?????? Or a Jenvey dealer in the USA, seeing they are next on my list from what in reading they are the best fitting for the S2000 chassis along with Hayward which really is jenvey.

PM "bug man nrg" he is a Jenvey dealer here in Florida. He has done a few group buys for s2000 owners I believe.

ITB's are extremely challengine to tune with a MAP-based system, so combining those challenges with the added weaknesses of a piggy-back system would make it exponentially more difficult. I am not familiar with GEMU, but I really don't think it would have any of the features that would be needed to make it possible (non-linear MAP adjustment for fuel AND ignition, etc.).

I'm considering kpro instead but it's pretty expensive and the installation seems to be a major pain, maybe worth it in the end though.

I can't imagine why it would have those features, since they aren't needed for conventional NA and FI applications. Basically, the fuel map is pretty linear below about 850 mBar, then it gets very exponential. From ~850 to ~950 mBar the fuel requirement doubles, and it's non-linear between those points. Using my FlashPro, I have to increase the resolution of the fuel and ingnition tables at the upper load levels so that I can tune at about ~10 mBar increments. The stock tune uses ~100 mBar increments.
