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.

      r34's love to squeal

      just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.

      My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.

      To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?

      So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
