I guess what I am asking is what would make Ivan’s and Brocks maps so great if they are actually a generic map for a another bike they tuned?
Well, I can only speak for myself here….
I am not of the belief that all bikes are different… this is proven to me with my jet kits from carb’ed bikes from back in the day. (there’s nothing black magic about standard production tolerances)
It was easy for some of the other kit makers back in the day to say that “all bikes are different” because it was easier to say this rather than keep a better control of the needles dimensions that weren’t the same from batch to batch….. all it took was a .0005” difference in the diameter of the needle (in the area that was used while the slide is down) to make the bike need to have the needle run a different clip position…. The same idea goes for the distance from the e-clip area to the first taper… a .025” difference will cause the needle to be adjusted to a different height.
Bobby, I know that you have installed many of my ZRX kits and they all run the same setting according to what mods have been done…. This is because my requirements of my machinist are to be accurate to .0001”….. With these tolerances, I never have to worry about having a “matched set”, and I don’t have to worry about people needing different settings 99% of the time.
A “generic map” is a web board term referring to a map that was made by someone for a particular bike that should be pretty close to what is actually needed….. This is where I get “lumped in” with the rest of everyone else… this is because people think that my test equipment is the same as everyone elses.
This is not the case for me… I do not suscribe to Dynojet’s Tuning Link, nor do I feel it is the best way to tune… Maybe I’m old school, but I feel that an old fashioned EGA is a much better tool to check exhaust gases with…. For sure it takes a lot longer, but the analyzer’s readings are much less affected by exhaust temperature, and dilution of the gas from exhaust resonance drawing in fresh air from the end of the pipe at lower rpms…. This is the type of stuff that makes wideband readings go to extremes and makes them go nuts…. Just from the very principles of how they work. The EGA is un-affected by temperature because it reads gas content through infra-red light.
I believe he reason that people get different maps for the same list of mods is because of thew nature of the wideband… you can go to the same dyno on 3 different days and get 3 different maps made…. This is why I don’t suscribe to the same stuff that everyone else does.
I believe the reason that it exists is to make it easier and faster for the dyno operator to make his adjustments…
(let the software automatically make it’s adjustments with the readings taken from the wideband)
If the wideband was located 6 inches out of the exhaust port, I would tend to believe it’s readings… But at the collector there is a 1000 degree difference and even more at part throttle…. Locating the sensor outside of the pipe and pumping the gas across it makes things very erratic and even more heat is lost. I know that these sensors have heaters, but this is only a poor band-aid. The only place that these sensors work well is upstream of a catalytic converter or in a turbo application where there is no resonance to make erratic readings.
Anyone who has seen one of my maps on the screen will tell you that the format is very different from one that was made with a wideband.
If you get a setup from us, you are getting a specific tuning program for a particular set of mods that will be difficult to improve upon because of the amount of time that I have put into it.
All my maps are the result of months of testing in a variety of weather conditions… If you like smooth and precise, you will like what I offer for the ZX14… the big hp #’s are easy to get… maintaining driveability is a lot more time consuming and much harder to do.
I hope this sheds some light into my take on tuning bikes,
Ivan
