i don't think he really cares to have maps for every little mod people do. He is just happy to have a base map that works for the masses. Pretty much like I had. Filter, full system, block offs, and his standard derestricted ECU. (kinda depressing mod list compared to all the different items I had before and now the ECU replaces it all - PCIII, PC Ign, TRE, Servo elim...)
Basically he relies on people to do their own data logging and then send him that information along with the ECU and then he will write the map. Then you have to install it again and check it and if you need any more changes send it back. Great for those people who really want it all done through the ECU and have no means to get it to a tuner capable of flashing the ECU, but a pain for those of us that have the means to get to Guhl and would rather just pay to have it done in one shot. Before I went with the flash I started doing my own data logging with a Wego and it was just a pain to ride to work or where ever and then download the data, then ride home and download the data. Then I had to transfer that to the fuel module and do it all over again the next day. I liked the idea of doing it all myself, but I just didn't have the time at those points in my day to deal with that. Plus who wants to take their bike out of service for a 1-2 weeks while UPS is transporting your ECU?
