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 ...

There are two different types of oil life indicators, as discussed on this page. First, there is the Algorithm-based one: Algorithm-based oil indicators measure lots of factors and then plug the resulting numbers into a formula. Based on the answer to this complex, ongoing math problem, the indicator display will tell you whether the oil is OK, is close ...

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 ...

Yes. That is a significant difference so your speedo will be out by a lot. In some regions it is required by law to have an accurate speedo!

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. I can't say by how much though. These chips usually give an MPG boost of around 10%, so I would imagine your true MPG ...

Yes in theory it could be done. But getting the mechanical components to work would be difficult and probably result in an awkward and bulky addition to your car. I suspect the end result would be an expensive and unreliable disappointment. It would probably be easier to change the entire gearbox for automatic or a sequential box than try and adapt a ...

There is a manufacturer out on the market right now who actually does this. Magneti Marelli has an Automated Manual Transmission or AMT. This was discussed in this thread.

I'm not familiar with the car, but could you not create a temporary cover/box out of some light plastic or aluminium sheet? 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. I ...

Your instrument panel is part of the ECU on your vehicle, electrically. If the GEM has been substituted and still the problem has remained, a critical look at the instrument panel is required. Moisture or dampness, even a water entry from the windscreen, could cause corrosion to the IP and cause mis-function. Fords had this problem with European Focus's.

Yes, the wheel speed sensors can detect if the vehicle (or at least the specific wheel the sensor is tied to) is moving. On most vehicles you should be able to tie directly into the wheel speed sensor and detect the signal, while not causing any issues with the vehicle itself while in normal operation. The sensor itself is a standard sine wave orientation. ...

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 ...

I was looking for the similar thing and stumbled on a page which describes the protocol for the 650gs. I haven't managed to try it out yet but it seems promising. http://www.f650gs.crossroadz.com.au/Diagnostics.html Topic is discussed here as well: http://f650.com/forum/showthread.php?25550-Diagnostic-plug-pinout-does-anyone-have-it Plese let my know how ...
