I thought I would provide an update as we have been running M112s on a 93 SC400 with, 315cc injectors, R-154, upgraded suspension, clutch, LSD, S&S short headers, and on a 95 SC400, W-58, 315cc injectors, uprated clutch, LMF long headers. Both with a 3” pulley and stock throttle body.
The M112 works very well on the 1UZ with a stock computer but it has limitations. Notably the transition to boost is hesitant unless WOT, the throttle body looks and seems restrictive, decel fuel is set up for an automatic therefore it can be rough when decelerating quickly, the 315cc injector plus the cold start injector is way too rich on start and generally too rich at low rpm. The 95 computer without the cold start injector does run rich at idle but runs well. The traction control gets real sensitive under boost and chokes off the throttle body way too quickly.
