For example, you can change the commanded A/F, timing, turn off/on things like the fuel pump, perform a CASE relearn, cylinder balance, etc.

Of course there is always the garage (with scan tool) route; howerver, is there a "manual" way to perform a CASE relearn on the H3 instead of using the HPTuner, Tech II, or similar (expensive) scan tool?

Here is a "manual" write-up I found:

If the Crankshaft Variation Relearn is not accessible through your scan tool some truck applications 1998 & later), perform the relearn in the following manner:

1. Turn off all of the accessories. With the Air temperature sensor and
Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes.

2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8-10 minutes until the engine reaches operating temperature.

3. Cruise at 55 mph for another 5-6 minutes.

4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.

5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.

6. Accelerate to 55 mph and cruise for 2 minutes.

7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.
