The Honda article posted yesterday is some interesting reading. Towards the end of the article, the Honda rep seems to say that Honda has not approved any recalibration tool besides their own though they are working to approve other companies. This brings up a valid question about Opti-Aim, Bosch, and Safelite's systems. Even though these companies are stating and verifying proper recalibration, how many of the vehicle manufacturers will approve?

None. In fact, most OEMs claim their calibration process and tools are proprietary. Don't believe me? Well then, ask any of the aftermarket purveyors to show you anything from any OEM that states their aftermarket calibration tool has been certified by any OEM to perform re-calibrations on their vehicles. Remember, this is not like the manufacture of glass, where arguably a standard exists. There is no standard for re-calibrations. Thus, it would seem that each OEM process (and tool) must be the de-facto standard for their vesicles.

But hey, what do I know....

If the cars computer says it recalibrated then it is.

putting your their stamp on it may be a liability issue
but its more like a revenue issue

They will not "approve" any aftermarket system for anything... How could they as they do not know what these systems are doing, and it is not in their interest to find out. Just like they do not approve of the calibration tools used everyday to tune transmissions / fuel injection.

The vehicles respond back when they are calibrated correctly. It is all you need.
