I Program hot rods, sports cars and trucks for a living and I found it odd that there isnt a product that will help with the tables for spark tuning. It seems from what I hear that you can only do fuel, is that right? And does anyone know if theres a way to change spark for advancement. Theres alot you can do when it comes to changing the spark advance and how much to retard the spark to gain HP, Torque and fuel economy at the same time.
Let me know if anyone has any experience with this stuff on atv's. Ive never tuned a atv before and dont want to buy an inferior product so let me know whats the best.
