I have an old 2002 catalogue for HKS, and no ECU is listed.

However, there are a number of add on's such as Turbo Timers, EVC's (boost controllers) including what they called an EVC Pro that:

Designed for highly tuned vehicles and race applications, the EVC PRO is adjustable up to 3.0Kpa (43.51psi) with the functions of the EVC IV
and additional race tuning features. The EVC PRO takes input from the vehicles ECU to allow for adjustments to boost characteristics to enhance performance. Boost curves can be programmed to variables of engine rpm and throttle position or vehicle speed.

I have one that is coming out of my car. I have the upgrade with the Sport Turbo and HKS FMIC. I'm taking out the Pfcon, the wire harness, fuel cut defenser and boost sensor out and going with the Rtech 2.1.

But, you're talking about old, my friend, but, it all still works.

Let me know if you are intrested.
