Kawasaki KRX 1000 AA Custom Tunes for PV 3 & 4 by Aftermarket Assassins

**Tunes ONLY**

 Fits 2020-2025 KRX 2 & 4 Seat

• Already have a DynoJet PV3 or PV4 for your KRX 1000?  You can simply purchase our tune(s) for your current device and load them right into your ECU 
• Need a mount for your PV3? Check it out here: AA KRX PV3 Gauge Cluster Mount
• Are you looking for the most badass tunes available for your Powervision? Here you are! These tunes are for customers that already have the Powervision for the KRX 1000. If you are looking to tune two vehicles with your Powervision 3 (PV4 not applicable) please read this page thoroughly before proceeding. If tuning two vehicles with your PV4, the app will prompt you to purchase a License for the additional vehicle. We are highly experienced in tuning the KRX models and that will show. Our tunes are also easily labeled and will show rough horsepower claims 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 KRX.  Each tune is built specifically for your Powervision.  We need you to send your PV_INFO file to us before we can send the tunes. For more information on how to get this, see the below description, or this VIDEO (PV3 only in video).
• Big horsepower gains! The factory timing map is very de-tuned on the KRX which allows us to easily wake things up
• Quicker throttle response and power delivery
• Throttle by wire tables are modified for better response, especially in high range.  Low range throttle mapping is a little better, but still left mild for good crawling. 
• Full throttle/power in reverse (factory limits reverse throttle)
• AA's wicked timing curve built for 91-93 octane fuel
• A great fuel curve that gives much better low end (as well as all around) power as the factory map is very lean in key areas.
• Accelerator enrichment is optimized for better fueling and vehicle response when stabbing the throttle
• Fan on/off temp lowered to 185/180 degrees Fahrenheit (Stock is 189/183)
• Winter tunes (runs hotter but safe coolant temps) available for those with cabs/heaters in cold climates. Easy to switch when seasons change!
• Seatbelt limiter disabled
• Speed limiter removed in low and high gears
• Rev limit at a safe 9800 RPM (Stock is 9500 RPM)
• Best peak power when tuned is 7000-7300 RPM at wide open throttle around 50 MPH in a full power run

• Level 1 Tune: Built for the OEM exhaust (cat removed is okay) and 91-93 octane.  Gains 10 RWHP in some areas, and on average 7-8 RWHP when combined with our clutching. This takes your KRX from roughly 112 factory rated crank HP to 125 HP.  The AA S2 Clutch Kit is highly suggested with this tune.
• Level 2 Tune: Built for an aftermarket exhaust (slip-on or full system) and 91-93 octane.  Gains 16-17 RWHP in some areas, and on average 14-15 RWHP when combined with our clutching and exhaust. This takes your KRX from roughly 112 factory rated crank HP to 135 HP.  The AA S2 Clutch Kit is highly suggested with this tune. 
• Race fuel tune 95-100 octane maxes out our timing curve to where we see peak power.  This gives you another 3-4 RWHP on average over the pump gas tunes. 
• More tunes are coming, if you have any specific needs please let us know!
• Wondering why go with our tune(s) over other tunes? We go the extra mile to make sure everything is gained, and have a few extra tricks up our sleeve because we test in the real world. Our facility is on 40 acres, and right on the trails. We data log and finalize all tunes not on the dyno, but in real world conditions which makes a massive difference. Other dyno tuned only maps take their time to hit peak timing numbers which really hurts performance. Our map gets you into peak timing quicker, so max power seems more instant. We also have a great fuel curve that is designed to go with our timing curve, and offers better fueling for more power at WOT.  We also do some work with torque limiters as in the dirt we saw throttle closures when spinning the tires. Our map fixes that issue giving you 100% locked power delivery.  We also do the easy things like up the rev limiter to where you will never hit, disable 2 foot limiters, and disable seatbelt limiters.
• Tunes are said to "Ship for free" but will actually be e-mailed over to you within 24 hours of placing your order (Weekdays only).
• Not good with computers? No problem. Simply send us your Powervision (PV3 only) and we'll install the tunes for $25 which includes the shipping back to you.
• PV3 Users to send PV_INFO: To get your PV_INFO number simply plug your Powervision into your computer (No software is needed and this will work on an Mac or Windows computer) using the supplied mini USB cord. Wait for the POWERVISION device to pop up as a drive. Once it pops up, open the folder for this device.  Inside the folder for the POWERVISION you will see a PV_INFO file which will need to be attached into an e-mail and sent to aftermarketassassins@gmail.com
• PV4 Users to send PV_INFO: With your PV4 connected and app open on your phone, Hit "Scan" to search for your connected PV4.  Tap on the "Dynojet PV4".  Your Connected Vehicle should show your VIN and ECU information. (Verify this information matches your vehicle) Select the share icon next to "Connected Vehicle".  Select your e-mail app (Gmail, Yahoo, etc.). This will open a new e-mail with the attached PV4/ECU information.  In the "To" line, fill in with   aftermarketassassins@gmail.com  .  In the "Subject" line, fill in with your name & invoice #.  Please note that if your e-mail associated with your PV4 account is different than the e-mail you are using to send the info, please make special note of this and attach the e-mail associated with your PV4 account.  Send the e-mail and await further instructions when we send your tune file(s).
• PV3 Users to download tune(s): Simply download the tunes from the e-mail we send and find where they are located (usually the DOWNLOADS folder). Copy the tune files by highlighting them and plug your Powervision into your computer using the supplied mini USB cable. Wait for the POWERVISION to connect and open the POWERVISION drive. Then simply copy the downloaded AA tunes into the main POWERVISION folder with the rest of your supplied DynoJet tunes.
• PV4 Users to download tune(s):  Open the Power Vision 4 app on your phone. If you currently have the app open when we send the tune(s), you will need to completely close out of the app and re-open it.  At the top should be a "There are shared invitations" notification. Tap on this.  Tap on "Accept" to accept the tune(s) from Aftermarket Assassins.  Tap on "Tunes".  The new tune(s) will now be listed at the top under "My Tunes". DynoJet's tunes will be listed below (If applicable for your model).  Tap on the tune that you want to flash.  Tap "Flash Tune" If a License is needed for your vehicle, a "Redeem token" message will appear. Click "Yes" if you wish to purchase and redeem a License token for your vehicle.
• **Tunes are password protected so you will not be able to open or view them in the C3 tuning software**.  This keeps our tunes protected from copying, and gives us a good reason to keep putting in the time to make the best tunes out there!
