The Honda FI System
I have the most experience with DynoJet Power Commanders, having had them on 3 different bikes, all with great success. I know that DynoJet is bringing out a box for the Grom. There was one male/female connector that they were asking a supplier to get, or mold. Probably about 3 months away. I'll check this week.
I have a $600.00 Daytona dual O2 sensor system that is very accurate. So I can monitor the mixture regardless of the Honda system. I have already mounted on the bike and used it. If the system does not compensate for the big bore kit, I will change out the injector for a slightly larger Honda injector, and run all the tests again. If it needs a ECU black box, I'll get one, and make a file that works well, and give it with the big bore kit. I plan to test the kit with the stock exhaust, and my replacement exhaust system. I'm in line to get one of the first DynoJet kits.
One of the things that I discovered when I used the O2 sensor was that the system goes to 12.8/13.2 to 1 when you open the throttle to WOT. That's a perfect ratio for power. I can't test every exhaust system, but if you guys send out a few of the European systems, I'll test them and see if the file is different, and then provide you with a file.
I will not sell this kit without a fuel curve that works, period. If someone decides to pull off the whole induction system, and run a velocity stack, they are on their own, but I'll still try to help. If someone decides to run the big bore kit at 9700, and not to 8700, like it's designed for, I can't help them. Please remember I am increasing the displacement by about 36%. There will be no reason to rev the piss out of the 170 kit. Think small block Chevy / big block Chevy. There should be so much more torque, that I plan to change the countershaft sprocket to a 16 tooth, because it will pull it.
