Now you will drive the car and get it to have the issue youĪre having. Press the joystick on the right of the screen IN, and a message will pop up When the vehicle is running, go onto the dashboard screen and This allows for exact adjustments to be made ItĪllows you to check how the many functions the system can read and go through You have now reset the learn function.ĭata logging is a useful tool for diagnoses and tuning. The key off and wait for the numbers in the value side to go black. Menu and then up to the Dashboard and select it. Highlight this and push right on the joystick to go to #1, then save that to To reset the learn is a very easy procedure. If this happens, itĪlters the fuel map in ways that may not be optimal for proper running the Will try to compensate in order to keep the car running. Sometimes if there are outside problems such as bad misfires, exhaust leaks, orĪny other situation that could cause poor readings on the O2 sensor, the system System uses to adjust the active fuel tables it is using for operation. Once the throttle screw is in the correct position key the ignition off and allow the system to save.Īll Fitech EFI systems have learning procedures that the If the number is above 10 then turn the screw IN (clockwise) until the IAC Steps are between 3-10. If the number reads zero then slowly turn the screw OUT (counter clockwise) until the IAC Steps reads between 3-10. This number needs to be within 3-10 at warm idle. On the handheld go back to the Main Menu and enter into Dashboard. Once engine is running and at operating temperature turn ON Idle Set Mode. If the engine wont stay running without keeping your foot on the pedal a little turn the throttle adjustment screw clockwise another half turn. To get engine to start you may have to press the throttle pedal slightly. Enter into this menu and start the engine. Turn the key on and go to Initial Setup on the hand held. Once this happens, turn the ignition key to the Once in the dashboard, turn the ignition key off and waitįor all the data to blackout. Now go to Go EFI Initial Setup, then Engine Setup, now input all of the parameters that are needed for your application, making sure to save each one individually.Īfter you have entered your information and saved it, go up and After this is done it will revert to the main menu.
Once on this file select it, and it will download to 100 percent. Once in this menu scroll down to the second to last selection, it should say Default v8 T195. Then if still no error found you need to check the ECM.These are a basic overview of the most common setup questions.įrom the main menu, go to the very bottom and select Write Cal To ECU. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump." So what the means is that you need to check your pump, the relay after that the POS and the camshaft position sensor as well as all the wiring in between. The ECM does not directly drive the fuel pump. The ECM stops pump operation and prevents battery discharging, thereby improving safety. If the engine speed signal is not received when the ignition switch is ON, the engine stalls. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and camshaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine startability. Now here is how it all works according to the SM:" Mitchell1 you are not telling us what you have checked regarding the fuel situation. Ecu does connect and communicate perfect. Coil packs have power and ground but not seeing anything from ecu triggering the coils. Ive checked the timing and had my father double check all work (20+ year mechanic) He confirmed that I was on the money. And its also not starting with cam sensor unplugged. Sure enough, we were missing the O ring that goes there. However it started after unpluging the cam sensor and ran perfect unless you gunned it (I thought maybe the vvt solenoid wasnt getting oil pressure). After replacing the gasket I tested compression and had no issues there.
Prior to replacing the head gasket we replaced the injectors, coil packs, spark plugs, o2 sensors, cam sensor. maybe 8 hours of total worktime to complete. I replaced that myself as the dealer wanted $2000(14 hours) for the job that took me. Had missfire issues from blown head gasket.
