I bought a stock 2008 GSX-R600 out of a bike and I have a question,
I tested the car today and I couldn't get it to run clean over 1/2 throttle. It had no response and I had to baby the throttle to get it up to speed. If I stepped on the gas, it would just "Blubber" all over itself.
It is stock injected on gas. I tried everything from 25psi - 65psi for fuel pressure and the higher pressure I ran, the worse it got. Is there some sensors that I am running that I shouldn't be or some sensors I need to? Very frustrating. I have a Kinser airbox, Walbro pump with a 125 filter before the pump and a 25 filter after the pump.
Any help would be appreciated.

Is the box in safe mode? If you have access to another ECU, stick it on and see if it makes a difference. If so, have the original one reset.

I don't have another ECU, but I will see if I can round one up.
There are 2 sets of injectors,(top and bottom) Does it matter which plug wires go to which injectors? I noticed there are 2 color wires to each plug. One has green and yellow, the other has gray and yellow.
Thanks

I was going to suggest you talk with Lucky13 on the MaxDirt forum, but I see you already have a thread going there. I had a wiring issue with my R6 a while back, and didn't have the top injectors plugged in correctly. That put the box right into safe mode on me. If you don't, or didn't, have your injectors plugged into the harness correctly, I'm almost positive you will need to reset your ECU. BTW, when the box is in safe mode, it disables either the ignition or fuel to limit the motor to only running on two cylinders.

Raced this weekend and it was just as frustrating as in the garage.
Couldn't get over 1/4 throttle and it would blubber and have no response at all. I am at a loss.
There are 4 "vent holes that I had small breather filters on, 2 on the top of the valve cover, one on the back of the injection, and one on top of the tranny. I had them all vented, but was told that the 2 on top of the valve cover need to be plugged, so I did that. It didn't help much. What about the other two? (injection and tranny) Just looking for anything at this point.
I will check to see if I can find another ECU and plug it in and see if that is the problem.
Any other thoughts?
Thanks
