    Yes, the Closed Loop RPM Activation should be zero for most street performance applications.

    Do I or can I update my software as I bought this kit about 1 1/2 years ago?

    Starting to chase my tail with this setup as when it fouls the plugs the HEI distributor can then miss & cross-fire. I think it's not liking the cam as I have read the Comp Cam Thumpr with their tight 107° lobe separation angle. Have very low manifold vacuum at idle, as low as 8 to 10. I will be getting hold of a vacuum gauge today to see what I have. Do you know how low vacuum the Terminator can handle? Cheers.

    I think your low idle is caused by the throttle blades not open far enough. When you had the TPS not set correctly, the IAC was at 30%. This should of had the engine idle close to 2000 rpm, but it didn't. If a 100% IAC doesn't bring the idle up, then the throttle blades need opening. I would open them until the idle is too high, do a TPS AutoSet, then work backwards to get the right idle.

    I would go back and start with a new Global Folder.

    Yes, this is what I'm going to do next. I have the throttle about 1 1/2 turns out from seated already, but I will go further & work back. I need to stop it fouling the plugs so it can self-tune (Learn). Thanks.

    Your cam will make it a little harder to tune it, you will need to use a laptop to get it better, as you have low vac it will move the idle cell to a area that is richer, if you use the laptop you can change the map axis as you will only be using half the map axis that is in the system, this will make it better and will lean it out at the same time. it will also give you better resolution in the fuel map for the engine.

    It's probably V2 EFI software/ECU firmware. No need to update. The excessively rich AFR, may be due to the base calibration. See post #9.
    Ensure you're using the latest EFI software & ECU firmware (Link); it has "Oxygen Sensor Control Updates" (Link - HEFI_1589.eep).

    I think it's not liking the cam as I have read the Comp Cam Thumpr with their tight 107° lobe separation angle. Have very low manifold vacuum at idle, as low as 8 to 10.
    What size camshaft is it (duration @ .050" lift)? How many lbs/hr of fuel is in the idle area of the Base Fuel Table?

    Inlet 235 exh 249 Don't know how many lbs/hr of fuel are in the Base fuel table I will check with the next run. Was thinking if I change the target AFR TO 16 AT idle to see if the ecu could even get it that high I wouldn't leave it there just something to try Good or bad idea ? My first run was on STREET/STRIP than I tried Mild Street back now to Street/Strip as you suggested it is better here.Cheers

    I would connect a laptop "Online" with the ECU, and manually tune the idle area.

    If you'd like to manually tune the Base Fuel Table (even while the engine is running), read below:
    Left click & drag to select a group of cells, then use the CTRL & Arrow keys (▲►▼◄) to change the highlighted cell values.
    The ▲ & ▼ arrow keys adjust the Base Fuel Table slowly (one tenth at a time). The ◄ & ► arrow keys adjust it rapidly.
    Or you can left click & drag a group of highlighted cells, and right click "Offset Selected" to adjust the entire cell group.

    Also, ensure the Base Fuel Table is smooth by viewing & blending the Fuel Graph. It's important to have a smooth Fuel Graph.
    One aspect of viewing the Fuel Graph: It's better to zoom in, by highlighting segments of the Base Fuel Table (left click & drag), and click "Graph".
    This method offers much greater detail. Looking at the entire "Fuel Graph" will almost always look smooth, because it's not as magnified.
    TIP: When the Fuel Graph is smooth, click "Conversion" (VE% Conversion mode) and continue smoothing the general contour of the VE Fuel Graph.

    OK thanks, will look into it. Can you use an IPAD? I see it's Windows based. Might just pay someone to tune it. Would like to get it driveable first.

    If you have to, just borrow a laptop and order a cable. The handheld won't help you.
    It's pretty simple once you get past the thought of it all.
    However, I'm still learning the system too, it gets easier as you go along.
    I have a 107° cam too, and thought it might not have been happy with it either, but I found no issue with reversion, etc.
    Once you do hook up the laptop simply, go into the Learn Table and press Transfer Learning To Base Fuel Table.
    This will alter the Base Fuel Table to match your conditions, yet you will have to do this
    a couple of times though taking the car out each time for a drive in varied conditions, etc.

    I noticed it's an old XA Falcon, so you must be a fellow Aussie. I'm in Melbourne area, are you local?
