<x-charset iso-8859-1>If I am not mistaken there are only 3 things that effect the mixture with the FI system.... 1. Pressure Sensor: Suck on the hose and see if the diaphragm holds pressure. 2. Fuel Pressure: Check with fuel pressure gauge at the appropriate spot, and adjust the regulator to 28-32 psi 3. Engine Temp (primarily the engine head temp sensor) More resistance in the snesor = richer mixture, I think a hot sensor is supposed to read less than 1k ohms. links on the D-Jet system http://www.retro.co.za/d-jet.html http://www.164club.org/fidjet.html http://www.914fan.net/djet.html good explanation here.
