I have a Mk1 racecar with ABF and abf ecu and injection, improved chip ,improved cam and head mild flow, still has K-jet high power fuel pump. Seems to have developed a miss or power loss irregularly but always inconvenienty for races. Unfortunately the loom i got with the motor was missing the obd11 port for scanning. Retained Mk1 wiring for everything else but the engine. Initially ,for 1 race, engine ran fine. Replaced plugs, coil and spark plug leads. Made sure oil level kept highish- is there a oil level sensor which switchs to limp mode ?? Kept fuel level high to maintain flow .Replaced fuel filter and cleaned air filter. Anyone got any ideas. Can Rubjonny or toyotec help. What wire is the obd11port usually, colour and spot on plug for me to retrofit ?
