Help, my blitz sbc-id electronic boost controller keeps on overboosting no matter what i do to the settings! Sure i can drive it normally and the boost will go up to 5 or 6 psi, but if i floor it - it'll go up to as much as 19 psi!!! My car is a an R33 series 2 gtst.

i don't know if i've connected the ebc solenoid correctly though. I removed the original solenoid and lines completely, then i connected a boost line going from the intake plenum to the blitz solenoid and another boost line going from the blitz solenoid to the actuator.

Check that the slip joints on the black tube that go to the intake manifold haven't worked loose and are still sealing correctly. Following the instructions there is only the black line going to the intake manifold, the other 2 lines are tapped from just off the turbo and just before the throttle body - you shouldn't be running any boost line from the plenum just the sensor line (black plastic).

Yeah, i used the original boost line coming out of the intercooler to intake manifold pipe and attached that to the 'in' part of the blitz solenoid. Then i connected another boost line from the 'out' part of the blitz solenoid to the actuator. I then blocked of the line that goes back into the induction pipe with a screw( its the line that used to be connected to the top of the original factory solenoid)

    • By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol
    • No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
    • Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.  
    • Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go
