What's up everyone — I'm Bob, running a 2024 Tacoma Trailhunter on 74Weld Gen2 portal axles, King 2.5" remote reservoirs, 37" Toyo RT Trails, and a COBB Accessport tune from CAMTuning Performance. Going to be posting more frequently here — figured I'd kick things off with something useful. The truck is hitting 30,000 miles, which means dealer service time. If you're running a COBB AP with a custom tune, there's an extra step before you hand the keys over: uninstalling the AP to return the ECU to stock. Here's the full process. Why You Need to Uninstall Before Dealer Service The AP "marries" to your ECU — it stores the factory calibration and overwrites it with the tune. If a dealer performs a factory ECU update while the AP is still installed, the stored calibration becomes invalid. You'd need to re-pair from scratch, and your tune maps may need revision. The simple fix: uninstall before service, reinstall after. Takes 15 minutes total. The Uninstall Process (Before Service) What you need: COBB Accessport (married to the vehicle) OBD-II port access (driver side, under the dash) 15 minutes Key in the ignition, engine OFF Step 1: Connect the AP to your computer via USB. Open Accessport Manager and check for firmware updates. You want the device current before any flash operations. Step 2: Plug the AP into the OBD-II port (under the dash, driver side). Let it boot and recognize the vehicle. Step 3: Navigate to Uninstall. The AP will read back the factory calibration, rewrite the ECU with stock mapping, restore the TCU to factory, and unpair itself. Important: The CAN bypass harness is NOT required for uninstall. Just the AP and the OBD port. Step 4: Do not interrupt power during the flash. Don't turn the key, don't unplug the AP. Let the progress bar complete — about 5-10 minutes. Step 5: Once the AP shows "unmarried," turn key off, unplug, done. The truck is running stock calibration and safe for the dealer. Pro tip: Store the AP somewhere safe while it's at the dealer. I keep mine in the center console. The Reinstall Process (After Service) Once you get the truck back, it's time to re-marry the AP. This is essentially the initial install process again. Step 1: Check if the dealer flashed any ECU updates (check your service paperwork). If ECU/TCU firmware changed, the AP will detect the new calibration during install — this is normal. Step 2: Install the CAN bypass harness — unlike uninstall, this IS required for reinstall. It isolates the CAN bus during the write. Step 3: Plug in the AP, select Install, choose your tune map. For a CAMTuning remote tune, this is typically Stage0 – Simulated Stock TCM. Step 4: Follow all wait timers exactly. The ECU needs time between module writes to reinitialize. Rushing the wait timers = communication errors. Step 5: After the flash completes: Key OFF Unplug the Accessport Remove the CAN bypass harness Reinstall the factory CAN terminator block That last step is critical. Skipping the CAN terminator causes network communication errors. Dashboard warnings, weird behavior — don't skip it. Step 6: Start the truck, let it idle, check for warnings (temporary ones are normal). Take it for a short drive — the ECU needs a few drive cycles to relearn. Tips from Experience Keep Accessport Manager updated — outdated firmware is the #1 cause of flash errors Enable Auto Off — the AP draws power from OBD even when the truck is off (how to enable) Back up your tunes — if the dealer does a major ECU update, your tuner may need to revise for the new firmware Dashboard warnings are normal after flashing — should clear within a key cycle or two Communication errors? Almost always the CAN terminator. Reinstall it, key off 30 seconds, re-select your map 30K Service Rundown For reference, here's what the Tacoma is going in for: Oil and filter change (0W-20 synthetic) Tire rotation (37" Toyo RT Trail on portals — the dealer loves these) Multi-point inspection Air filter check/replace Drive belt inspection Nothing exotic, but at 30K with portals, 37s, Kings, and a tune — good to have Toyota's eyes on the basics.

Installed 11/26/24. Have to sell as I'm getting into overlanding and this cap doesn't have the weight capacity I need. Its a beautiful cap and hate to sell it but I plan on hauling quite a bit of gear and so I need a stronger cap. Windows on the side and front. Rails on the roof (rack and towers not included). I'm in Richmond VA. Original cost was $3000 and I'm asking $2500 cash only. The ARE color code is 040 and Tacoma color is "Super White". If you're interested reply here and we can set up email and phone contact. Pick up only.
