The details
-
No. However, due to worldwide regulatory requirements, manufacturers have to adhere to certain parameters. We try to make the bikes as intended on the blueprints. Most bikes are really good, but the manufacturer has to throw a dart on the wall and hope to hit the target for every market.
-
You can expect torque gains in the critical RPM riding areas, making it easier to ride.
-
Yes. Remapping will give you the best benefit with a fresh engine. Our remapping is very safe and helps extend the life of the engine.
-
Don’t assume anything. You never know what the true history of the motorcycle was. We always recommend to do a compression test on 2 stroke and a leak down test on 4 stroke. Feel free to contact us to discuss the details on individual cases.
-
Better throttle response. Less flameouts. Better overrev. Lower cost than after market ECUs, with better performance.
Shipping
-
Please ensure that your ECU is well protected by wrapping it in bubble wrap and shipping it inside a sturdy box. Do not ship in a soft, bubble or padded mailer envelope. We are not responsible for damage to your ECU during shipping if it has not been properly packaged/protected. Insure your package for at least $400. We prefer UPS and USPS shipping.IF YOU SHIP with FEDEX OR ANY OTHER CARRIER, WE DON’T TAKE RESPONSIBILITY FOR DAMAGED OR LOST BOXES. Please mail to us at the following address:

It is typically 3 business day from arrival unless you choose express shipping. Please note, poor planning on your part does not mean urgency from our part. Please respect hours of operations and DO NOT CALL after hours, except for emergencies.
RACE ADV hours operations: Monday - Friday 10 a.m - 6 p.m. EST
-
Yes.
Technical
-
No, unless riding at extreme elevation. An engine needs room to breath or can even make excessive heat with too much compression. People that ride at sea level really should be careful.
-
Depends on the bike to get the maximum potential. Most of our recommended modifications cost only nickels and dimes compared to other competitors. We believe that when you pay over $10,000 for a motorcycle, it should have good components that only need tweaking.
-
Yes, it is highly recommended.
-
No, a standard spark plug is fine.
-
Spark arrestors can be problematic.
-
Yes.
-
YES. YES and YES!
-
Believe or not, many bikes have a problem before mapping (yes! even brand new bikes or bikes with low hours). You should not assume mapping will fix the problem. Sometimes it may but a lot of times, there may be other issues. We have included a troubleshooting section that we recommend you try before calling.
-
Everything we do is at 40:1 for 250 and larger CC displacement. We test at 32:1 for all 150 CC and below.. Again, whatever you like to run will not adversely effect mapping for the average consumer on a stock engine.
