1. What Calibration Make sure you are using an appropriate map for your engine combination and EFI kit An XT calibration won t work in a PF2 kit and vice versa Also verify there is a map loaded into the ECU With the key on grab the calibration module and press the ENTER button on the lower left hand side of the screen you should see CAL EDL XXXX TAB XXXX being the calibration number You should see the file you loaded into the ECU If not go back to the computer and re load Distributor The ProFlo system operates off the distributor so if this is incorrect then you will have problems everywhere Go over the distributor installation and verify all steps were followed Make sure that all the components in the distributor are tight and locked down such as the shutter wheel and hall effect sensor Confirm the rotor has no advance movement Also be sure the correct shutter wheel is installed in the distributor call Edelbrock with any questions Ensure that the rotor is pointed directly at a terminal on the cap when the engine is at 10 BTDC and this terminal is going to the 1 cylinder correct phasing Inaccurate rotor phasing can cause spark scatter at mid to high RPM s Air Fuel Requirements Cold Start and Warmup The combustion process requires vaporized fuel Much of this vaporization occurs as the air and fuel droplets are drawn past the intake valve but a large portion must take place before the valve op2. Change the Cranking Pulse in 500 increments For example if the engine needs more fuel for cranking we would change the value to 2500 If the engine is hard to start try holding the accelerator pedal open at a steady state at about 50 throttle and try to crank the engine if it starts up easier than before then the cranking pulse is most likely to high try entering a smaller number If it starts worse try entering a larger number close the throttle and crank Repeat until engine starts within 3 5 seconds of cranking If you have tuned crank fuel but nothing seems to help monitor your battery voltage on the calibration module while cranking A properly charged battery should maintain 10 2 10 5v while cranking If battery voltage drops 22 below 10v while cranking it will cause problems with start up Vou mav need tore evaluate vour electrical system if you experience voltage below 10v while cranking If you still experience problems with starting check to make sure you have the most up to date firmware available Cold Start Fuel NOTE The LED s are not accurate at idle Tune A F to the highest vacuum level Once the engine starts it will be running on the Cold Start Fuel tables until the engine reaches about 170 185 F The engine will require extra fuel when it s cold to prevent staling To change the amount fuel metered in this area of operation you will make changes in the Cold Start Fuel modifier in the Calibration Module or
3. Loading New Firmware If new or updated firmware is available from Edelbrock it is a good idea to load it into the ECU so the system will continue to operate at its full capacity and you get the best performance possible from your Pro Flo system You can check our website or with our tech line to see if there is updated firmware available Updates will also be posted on the electronics forum Call the Edelbrock tech line if you have any questions regarding updating your firmware To check what firmware version that is currently installed in your ECU connect the ECU to eFlash At the bottom of the eFlash screen you will see the words Version with a number in the box next to it ECU Connected Serial 57766 dock 559 34 Version 12 0 Resets 19 iLink Closed If the version of firmware in your ECU is older than what it is current then you will need to update When you download or receive the firmware from Edelbrock in an email the firmware will be in a compressed folder this will require you to extract or unzip the file Save the file to your desktop Once it s saved you can right click on the file and select Extract All or Unzip This will prompt the Extraction Wizard to start Go through the steps in the extraction wizard to complete This will save a non compressed version of the folder on your desktop Now double click on the new folder in the folder there will be an FSX file it will be named something like this 71E_01_8CYL_01
