Activating the Fuel Savings
The final step in installing the MTech Fuel Saver is to wait 30 minutes and then run the engine for five minutes between 50% and 60% of maximum engine rpm. We took max rpm to be where the thick red line started, which was at 6500, thus making 3250 the 50% mark and 3900 the 60% mark.
The five minute requirement was based on the mileage of the car, with younger cars requiring only two minutes.
We made the mistake of not waiting 30 minutes before revving the engine. We revved it for five minutes before discovering that we had to wait. So we waited another 25 minutes before revving it again. We're not sure if that ruined the activation process - hopefully not.
