Depending on the age of your Jeep the recalibration involves either swapping speedo drive gears in the tranny or reprograming the computer. The reasons for having this done are that modern vehicles use many data points for different systems and they all interconnect at some point. ABS, transmission shiftpoints,traction control, cruise control are all looking ...

Your Honda model has a history of failing transmission units. At the least, a once all-over check of the electronics would be advisable and be a bit of insurance against any faults. A Honda OEM/bi-directional compatible scanner would be required to program the transmission. The programming loads an operational 'map' for the system into the transmission ...

Great question. I am making an educated guess here, so don't quote me in court;) Because piggyback chips interfere with your car's various inputs I would assume that you are correct and that your MPG score will be inaccurate as a result.

Either stuck down in the same way as the carpet (although I personally wouldn't bother with carpet at this stage, get the important bits done first and worry about that later...), or screwed to the bulkhead either side of the ECU.

To answer your question ... you should NOT need to reprogram your computer (PCM/ECU) when you replace your transmission as long as it's a stock replacement (or stock rebuild). There is no reason I could find which said this, so I am thinking the person who is talking to you about doing this is trying to get you to spend more money ... on some service he's ...

My guess is that your long term fuel trim was commanding the fuel injectors to inject less fuel. When you start your car, you are running open loop (without the feedback of the Oxygen Sensor). In the warm-up phase, if your long term fuel trim is low, the car will stall since it is injecting less fuel than it was calibrated for. When you disconnected the ...
