Jay-
I just wanted to say THANK YOU for spending your time and hard earned money to look into this modification. The NSX community is better because of folks like you and others who take the time to figure this stuff out. As Honda continues to discontinue parts and jack up the prices on the remaining bits, work like yours will become even more important in keeping our cars running in top form.
Please do not get discouraged. I am sure people would flock to you if you developed a plug and play system to replace our aging and ailing 91-99 units. Look at Hugabuga- he took some time, developed a great system and sold over 100 kits, including to me. I have Titanium Dave's harmonic damper shield as well. As our NSXs get older people like these will become ever more important.
Based on your posts, I think these are the issues that remain with any potential Integra/S2000 swap:
1. Is the anti-lock proportioning (i.e., pulse signal sent to each wheel) accomplished in (a) the ABS computer, (b) the proportioning valve, or (c) some combination of both?
2. Is the wheel speed input signal modified in any way as it passes through the ABS computer on its way to the TCS computer?
3. If, as you say, we use the NSX ABS computer (in glovebox) to control the Integra pump, how do you prevent the ABS computer mounted on the Integra pump from interfering? It seems like you would have two computers trying to control the ABS.
