The design of
computer chips for today's automobiles has evolved into "one chip"
CPUs. On the SW20 MR2 the CPU + RAM + ROM are all integrated into one chip. These factory original CPUs cannot be reprogrammed and are not available
on the open market. TECHTOM Romboards offer the solution to reprogramming.
TECHTOM Romboards use the factory processor portion of the CPU and outboards the
memory portion to a standard EPROM for easy access to the data. TECHTOM
Romboards are ultra-compact and fit inside manufacturer's computer housings
(with the use of a small 1/4 spacer). No
need for "Piggy-Back". The result is the most dependable performance
enhancing system for the widest range of engines performance levels.
Tuned ROM features:
Remove factory fuel cut (for the conservative types out there, we can raise it to approximately 14.5 psi)
Raise factory rev limiter to customer specified amount (from 7200 rpm to approx. 9000 rpm, Our most popular option with stock valve train is 7600 rpm)
Lock out cold weather fuel timing maps - retains factory fail safe maps to protect your engine
Dyno tuned timing maps
Dyno tuned fuel mapping
