I just recently pruchased a worked EW 1.5l head from a guy on RPR.com The head was prepped by Gude Racing, and is equipped with thier Bullfrog cam, it also came with a port-matched Bullfrog TB. Ive also purchased a Mugen EW 1.5l Header and Mugen Cat. delete pipe (basically a test pipe). I am thinking about buying an SMC controller, cause I was told its basically a piggyback to the 1G Crx ecu, and that I can tune the A/F and Timing... But since the guy lost all the paperwork for the SMC, Im not sure its the right thing to buy. My question to you guys, is where can i get my lil rex tuned to use the HP output of the new head and cam.
