I have access to dyno and wanting to do custom tuning on my machine. I bought the vividracing IFLASH and I can successfully flash the ECU. BUT, I cant find a good editor. VIVID suggested WINOLS and I downloaded their demo and If you know what all that raw HEX data is then I guess its fine but figuring out fuel tables, timing tables and the ETC controls, fan temps and rev limiters and such would be impossible without having something that maps that out into usable tables. I bought the BITEDIT software and it partially works and their customer service is AWFUL so getting corrected maps to allow editing the data has proven fruitless. I tried contacting DIMSPORT and they wont even respond to request for information on their product and so I am here trying to find out if anyone is altering their programming or just using pre packaged tunes from other vendors which is fine if you plan to leave the motor stock and just bolting on some exhaust but for a good accurate tune on modified vehicle nothing beats strapping on the dyno. I have been doing that with GM vehicles for nearly 20 years and so I have been riding atvs for as long as I can remember and so I want to play with mine and then likely expand to buddies and so forth as I get a package setup. Much like Mr. RPM for can am stuff. their shop is like 30 minutes from me. through my business dealings i have people who do CNC head porting and such and if I can get this polaris thing going then developing a setup that works with some cnc ported heads would be awesome but that is a ways off. now I would just like to unleash my 900.
