So after putting the tremec behind my car a few years back I'm looking at adding injection to my car. I understand fast has a off the shelf system however I'm trying to save where I can. If one can obtain intake , fuel rails, injectors, throttle body, tps, and an IAT for reasonable would Megasquirt 2 be a sufficient ECU? I have a volley annihilator ignition that allows pretty adequate ignition control so fuel only might be all the control I need although ms2 allows ignition control as well. I realize I will need to change my fuel system as well. Looking for suggestions on both fuel system example surge tank with walbro pump using my existing system to feed it vs a complete rebuild, as well as ecu suggestions or anything else I'm missing here. Thanks in advance!
