I talked to a guy at bazzaz last week and on Monday to a guy from Dynoresearch. Bazzaz said they were talking with Yoshimura to develop some kind of controller for the Grom, but the guy I talked to didn't seem to think they got very far with it. Dynoresearch (the company that makes the Power Commander) say they are working on making a controller. They also said they were having some problems with the 1 wire O2 sensor and were working on a solution. They would not give me any kind of timeline and I didn't ask, but I'm guessing they will have something this winter. I like the idea of the PCV on the grom, I do a lot of engine mods and I like the ability to go into a program and tweak the maps at will.
I bought a 30mm throttle body from a CBR 125 cheap off ebay hoping the TPS, IAC and injector would have the same plug. They do not, the grom has a 3 pin TPS. One pin is the VCC or reference 5v, the other is the signal and the third is the ground. On the CBR it has 5 pins and When I removed it, it appears they integrated the IAT into the assembly, hence the extra 2 pins. It may work, but I need to compare ohm readings from the potentiometer on the sensor to see if the pots have the same ohm rating.
The Injector plug is different, but it looks like the grom injector should fit in there no problem and the stock fuel line as well.
The IAC also has a slightly different plug. I bought a cheap wiring harness from ebay and I believe it's possible to make it work if I can find a wiring diagram that shows me the which pin is what on the CBR 125. I also had a mounting flange from another build that fits perfectly and mounts directly to the head. This might be a fairly simple hookup once I find the wiring diagram for the CBR 125.
I'm definitely interested to see how this box you bought works out. I think it's very similar to the one Yuminashi has, the casing looks the same. Do you have an A/F meter with a wide band 02 sensor so you can adjust it correctly or are you planning on using a dyno?
