If you are looking for the most badass custom tunes that are easily loaded to your Defender HD10 from the Dynojet Powervision, you've found them! AA's performance tunes are offered loaded directly on the Powervision ECU tuner. This versatile tuner allows our tunes to easily be uploaded to your factory ECU, switch between tunes, and even return to stock. The PV is also a great gauge showing engine parameters such as timing and much more. You can leave the Powervision hooked up for gauges or completely remove it after flashing your ECU. Why AA tunes over others We have been tuning UTV's with CVT clutches for a long time, longer than almost anyone in our field going back to the 800 RZR. Tuning a CVT vehicle properly is not an easy task as you have so many variables at one time. We spend the time to wheel dyno(with actual UTV tires) correctly per modification, and have advanced ECU calibration and clutching knowledge to do so.
The Powervision also has excellent data logging capabilities if you download the software and use your laptop. You can even view trouble codes and erase them on the fly. We are highly experienced in ECU tuning and it shows. Our tunes are simply set up correctly and everyone with a Powervision should have these tunes! They are also easily labeled and will show horsepower gains with supporting mods such as exhaust and clutching. These tunes modify all the necessary maps to create big horsepower while still maintaining a reliable and safe Defender HD10. Each tune is built specifically for your Powervision allowing us to change various things like rev limit or fan temp if needed.
Every change in horsepower can result in us changing clutching several times. We also develop most of our supporting mods so we know everything works correctly, and build parts to fit the vehicles needs. Lastly and honestly the most important; we then back up our results with real world data logging on local trails and our facility on 110 acres. It's this combination that truly makes the difference and why AA normally has a faster vehicle with the same or less rated tune horsepower.
Horsepower gains are 3-4 RWHP on level 1 with stock clutching, but having the limiters removed and better throttle response makes it feel like more. If you clutch the vehicle for 6400-6700 RPM 45-50 MPH you'll gain 6-7 RWHP over stock. If you add exhaust and level 2 tune with clutching you are looking at a total of 9-10 RWHP over stock. Not just dyno tested. We are avid riders and like the factory, a ton of the testing is done in the field to make sure you are getting 110%. With data logging capabilities you can't get any better testing than real world. Often times we can make significant changes to further increase power, drivability, and feel of the machine that can never be done on the dyno.
Level 1: Stock Exhaust Systems Meant for stock exhaust systems only. Available in 87 octane or 91-93 octane.
Level 2: Aftermarket Exhaust Meant for aftermarket slip-on/full exhaust systems only. Available in 87 octane or 91-93 octane.
