Great thread, thanks for starting it Paul.
having just purchased an RE4R03A and eyeing up a standalone TCU I figured I better come to the sunny side to find out what I am getting into...
My car is a '94 s1 r33 gtst that I imported from Japan back in '05 and have gradually modified and occasionally wrecked in the subsequent years. The current RE4R01A box is standard except for a valve body / shift kit and coolers.
current focus is getting my newly fitted GT3582 working via an eManage blue which is proving a bit of an expensive pain, but once that's sorted I should be seeing some decent HP running c. 1.5 ish bar... The e-01 boost controller is struggling to hold the boost down in conjunction with the waste gate it's got fitted, and I saw a wallet troubling 3.23 bar at one point as we were messing about with the actuator, and I am struggling to build any boost at all in 1st and 2nd. All part of the fun.
not interested in manual, don't ask me why, I just like the idea of a fast auto skyline and in for a penny... So keen to learn from people who have been there and done it.
