There's a guy who does ECU flashing named CBlast. I recently had my Gen 2 ECU flashed by him. He offers a one stop solution, adjust fuel maps and ig timings and things like that in the ECU itself. Unless you plan on riding frequently in other parts of the country (elevations) or frequently are changing performance parts, you don't need a PCV or whatever that "lets you change maps when you want". That's all marketing, just to help you sleep better at night I guess.
I'm going to be doing some object testing, but I will say I really do think there is some difference in performance. I've never had this happen before, the thing power wheelied in 2nd yesterday.
His flash service is $300 for Gen 1 14s. But as I say, apparently his fueling and things are light years above what others are doing. His passion is 14s, although he flashes all ECUs on all bikes. Gen 1's apparently aren't nearly as refined as Gen 2s, and C's flash is really helpful for the issues you're speaking of.
Here's his website. I'm not sure exactly if he does what services and such, but I paid $400 for my Gen 2 flash. I'm positive when I do my objective testing (soon..probalby in the next month or two) there will be a proven performance difference. I bought a 2nd ECU to have flashed, so my stock one is in tact. Bike's acceleration will be tested with both ECUs in and compared.
- at least get ahold of him. You'll be hearing about him in the next couple years just like you hear about Ivan's, Guhl, Brocks, and those other guys.
