    Another GuzziTech exclusive... PC-V/AT-300 for your California 1400!
    Install how-to for your Cal 14. MUST be used in conjunction with a GT-Rx® ECU Performance re-flash.
    Contact us to order direct e-mail; Info at GuzziTech.com

    For details on steps 1-4, please see >THIS< thread:

    1. Remove fuel cap and trim cover. Re-install fuel cap.
    2. Remove lower tank trim that wraps the headstock and frame cover.
    3. Remove seat & rear tank bolt. Pull tank rearwards being careful not to scratch the valve covers (I HIGHLY recommend you remove the top cosmetic valve covers to protect them from this). There is wiring and a plug on the back right side of the tank, remove from clip/holder to allow slack.
    4. Remove Throttle Body covers.
    5. Lay the PC-V on battery tray, and route wires under the tank and air box bracket (bolts must be removed for this):

    Cal14PCV-1.jpg

    6. Route wires to each side, using the grey TPS wire feed to the right side, when seated looking forward. To gain some length on the TPS wire, feel free to remove the tape and pull it to the loom split closer to the PC-V. If I have time before I send yours, I will do so for you.
    7. Un-clip stock injector plugs by carefully removing the wire securing ring.
    8. Plug the stock injector plug into the PC-V harness, and the PC-V female plug into the injector:

    Cal14PCV-2.jpg

    Cal14PCV-3.jpg

    9. Under the back of the tank, you'll find the TPS plug on top of the throttle body assembly. Remove the TPS plug by sliding the yellow locking clip rearwards and remove the plug. Using the Posi-Tap, connect to the yellow/black wire, and re-install:

    Cal14PCV-4.jpg

    Cal14PCV-5.jpg

    10. Re-install tank and all trim/covers (1-4 above), and throttle body covers.
    11. Remove plastic trim and exhaust heat shield on the right side of bike to expose the 02-sensor/lambda plug. Remove 02-sensor and re-install new wide-band sensor from the AT-300 Kit. Connect the harness, and route to the left side of the bike. Water-proof the stock harness plug (I used heat shrink-wrap). Replace cover.

    Cal14PCV-6.jpg

    12. Remove left side plastic starter cover and exhaust heat shield to expose the 02-sensor/lambda plug. Remove the stock 02-sensor and unplug. Water-proof the stock harness plug (I used heat shrink-wrap):

    Cal14PCV-7.jpg

    13. Install the new wide-band sensor, and route both cables and extensions and zip tie as shown below:

    Cal14PCV-8.jpg

    14. Remove side cover (California 1400 emblemed) and route 02-sensor wires upwards behind frame:

    Cal14PCV-9.jpg

    15. Install the 02-sensor wires following the instructions carefully to the AT-300, and mount as shown:

    Continued from above...

    16. Shorten the AT-300 power and ground lengths to fit. The red power wire goes to the plug below, and ground to the battery. Use the white end-capped plug connector to power the AT-300, using the middle green/black wire. Verify this is a switched 12V power source before connecting. The bottom green/red is 12V, but not switched:

    Cal14PCV-11.jpg

    17. Remove the battery/ECU cover to expose the battery ground. The PC-V can get velcro'ed to the outer cover per below - position to sit directly in front of the AT3 unit, and clear of the frame rails or any obstructions. Route both the PC-V & AT-300 grounds under the frame rail, and ground both at the battery.

    Cal14PCV-12.jpg

    18. Re-install the side cover, and start the bike to insure all connections are good. Once verified, re-install all covers, and be sure all wiring is free from any pinch-points or high-heat areas. The only thing that must be done is to Calibrate Min/Max Throttle Position, covered online >HERE< -- Ignore the Dyno note; Warm the bike up, click reset and take one quick stab to full throttle (make sure you hit the stop)... You can manually adjust the idle millivolts (left side box) so that you get a fairly stable 0% on screen at idle, and then click OK. Be sure you see 100% on screen when stabbing the throttle to wide open.
    Both PC-V/AT-3 are sent pre-mapped and all connections in place. Do not modify or unplug any cables or the diode end plug on the AT3. Also, do NOT ever update the Firmware or Modify the Target AFR table without first consulting us.

    19. Enjoy your new machine!

    Howdy, I hope this is were this reply should go

    I have been reading and looking around your site for well over a year as a guest. Two and a half years ago I was hit by a 1 ton truck. After one of my back operations I went to kick some tires and saw a white 1400 touring now it is mine and for as long as I can get my leg over the bike and put my butt in the saddle, every day will be a good day for a ride!

    Now to get to the questions, I have read most of the post about the lean conditions the 1400 has and the Power Commander 5 and Autotune but after reading Todd’s post the step by step PC5 & AT install. And many other post about resetting the TPS and resetting the maintenance light and trouble codes I have these questions. First, in the install post there is no mention of resetting the ECU TPS! Yes or no? if yes what do I need to do it myself?

    I Love this bike and I think it is funny when some of my old Harley friends start to look it over and then try not to look as if they like it too much, And then there is the fact it runs like a raped ape, and not one of the plain apes but one of the striped ass ones, it does have some low end surging but I can see a Power Commander and Autotune with ECU flash in the very near future. Thank You David for your replies.

    Install went fine, at the same time I did the alt fix, and deleted the check valve on the fuel tank and charcoal canister. I have only put about 300 miles on it since the upgrades but so far I would highly recommend it. No new exhaust yet, Todd is going to quote me some of his mufflers except longer for a touring bike. Hopefully this summer things will fall into place and I can get his full exhaust.

    are there instructions for this? I found a cali install i followed for the electronics. now I'm to the point of the exhaust. what is the little screen for that comes in the bag?

    can I ride once the exhaust is installed and o2 sensors are connected? does it matter which side is 1 or 2?

    thanks...

    Combined here with the 1400 install thread. Yellow and white wired PC-V plug is right side. AutoTune #1 is left side, #2 right.

    Screen?

    ECU flash MUST be done first before you run the bike and the PC-V/AT-300 installed at the same time. DO NOT RUN THE BIKE WITHOUT THE FLASH DONE FIRST.

    You should have gotten them via email, and a link to download the program. If not, email me direct; Info at GuzziTech - the Forum here isn't my Inbox or where I can communicate like this. ;)
    Also, PDF and link to a video here; https://www.guzzitech.com/forums/resources/gtm-ft-manual.217/
