ATTENTION

Guhl Motors has moved to a larger facility. Please Note our new address: 102 S. State St. Ephrata, PA 17522-2411

We are traveling to a couple racing racing events, therefore, we will not be flashing any ECUs Monday 06/12/2017 - Friday 06/16/2017 and Monday 06/26/2017 - Friday 06/30/2017. Any ECU received during that time will be flashed during the next week. Please plan accordingly.

Though it is easy to tune a system for high peak numbers, it is much less simple to tune for drivability and overall performance. You will also want to be sure that the dynamometer is best suited for your application. Choosing the right dyno will eliminate inconsistencies of the testing/tuning process. Be sure that you are tuning for all variables in the entire system so that maximum power can be achieved; these include fuel curve, intake stack length, exhaust system, ignition/cam timing, and air box. When you leave the dyno, you will not only have optimized your fuel curve for peak performance and maximum drivability, but you will also know prior to race day that your system is operating correctly.

During the tuning process, your tuner should be asking questions about the type of track you race on and the driver’s experience. These are all factors that contribute to optimal tuning. Generally tuning for the “big” peak-power numbers does not make the best race engine. Big peak-power numbers are usually attained by sacrificing mid-range power which hurts the all-important corner exit performance. Different tracks and driving styles require different power curves. A track with long straights and tight turns requires very wide power curves that drive the car out of the turn and continue to pull to the end of the straight. Small tracks with sweeping turns and short straights might require a more narrow power curve for best performance.
