vidospace Posted August 24, 2008 Share Posted August 24, 2008 Hi all, Just installed a HKS EVCIII on my R34. It seems to be working perfectly until 3rd gear. Then at around 3000rpm, I get a boost cut and the unit beeps twice, like it does when it hits the warning. Anyone got any ideas? I havent driven it a lot yet since I installed it, but on the test run this was the only issue I came up with. I set the high and low boost to the same 0.75 bar and the same thing happens. I cant see it being a dodgy solenoid as it holds boost and stops it going over 10psi fine in 1st and 2nd. I am thinking it might be some sort of fuel cut happening, but it doesn't happen in 1st or 2nd so that's weird. Would a FPR help though? Fuel Cut Defender? BTW I am not running a aftermarket computer (as yet) and the only other mod is a turbo back exhaust. Vidospace.

Johnny Posted August 24, 2008 Share Posted August 24, 2008 Check the little filter before the solenoid, if its dirty with oil it can disrupt the reading and maybe thats why its cutting out.
