I'm getting a rev cut/limiter at about 5200 rpm. There is no cut in neutral. I'm using a hondata s300. I'm sure I'm getting sufficent fuel. We tried disabling pretty much everything. We checked ALL the setting- Rev limit was set to 8k, boost setting was plenty high. launch setting was disabled, we tried disabling v-tec, we disabled fuel and ignition cut offs, I'm probably forgetting some of the setting, but we went through all of them and tried everything. I have a 3-bar map,550cc inc.,walboro 255 fuel pump. It was consistent 5200 every time and didnt matter what gear. So any ideas would be greatly appriciated. thanks Oh I think I have a bad timing belt tensioner, its squelling. I'm not sure if that could be part of the problem?
