This is a cross post.

Through a friend in Tokyo, I have been asking the people at A'pex Integration (Apexi) if they will making a control computer suitable for the RX-8.

A'pex are well known for their aftermarket items for the RX-7 cars.
Their Power RFC and Super AFC-II are electronic devices to manage fuel/air and turbos on RX-7 and other autos.

I can testify that their management computers and boost controllers are awesome. A friend of mine has a 3rd gen RX-7 with a lot of their components fitted, and once he added their computer he says it is like driving a different car. Smooth idle, power is abundant, fuel economy is improved and driveability much better.

In talking with them they say that they are very interested in producing their products for the RX-8.

However, they need an RX-8 owner in the Tokyo area to volunteer his car for a few days, a few hours per day, for testing and fitting purposes.
To quote, translated into English:
"their requirement is that you have to bring car in for their factory outside tokyo several times for few days for benchmark "

So, if anyone can get in touch with an RX-8 owner over there, it looks like we might have something useful out of it..
