So I have been a little depressed lately, my car is OBD2 with a coil and igniter in one solid unit for the ignition. Since the igniter is in the coil I can not use the MSD BTM or the EManage to tune my timing under boost. This means I am limited to around 4-5 psi and even then it might not be safe. But after searching for awhile I have found something, the Split Second TMC1! The split second TMC1 retards timing based on boost much like an MSD BTM but it alters the crank angle sensor and camshaft position sensor signals instead of the wire between igniter and coils. This allows for the whole ignition system to be left untouched and functioning as normal. The 4 wires from the two sensors go into the unit, 4 wires come out and return to the ECU. Two wire supply 12volts power to the unit, a vaccum hose for boost reference, and there is even a wire for dash lighst so it lights up on your dash at night. Knob adjustment, low and high rpm adjustment, and reterd per pound of boost. Looks like I will be testing this out! It was originally meant for Toyota ECUs and the tacoma supercharged guys use it a lot aparently. Mabe add this to turbo sticky?!?!?
