Hi all,

I've got a Blitz SBC ID installed on my R33, everything was working fine, and I mean fine, was doing everything it should.

BUT!! Now something has gone terribadly wrong!

The car seems to have dropped down to standard boost despite what i set the boost to on the controller. I have tried the boost on auto, manual at high boost and low boost, but still the car boosts the same. Also messed around with the gain setting but no real love there, I did notice a VERY slight difference in response when controller was set in manual and boost was set to 100, but boost peaked at 9.6psi.

An interesting thing to note is that when I have the boost set very low ie. 1psi the alarm trigger on the controller does not activate.

Also, I pulled the control box for the unit out (the silver one that you tuck away in the cabin) and checked it over with the multi meter, the box had the needed 12V to the supply and was outputting 12v on the common and what I would guess are the step 1 and step 2 solenoid returns, now when I set the boost to 1 psi and blew with my mouth on the pressure inlet to the unit, there was practically no change in voltage on any pin, cept for a slight dip to 10.5V approx on one of the solenoid feed/returns.

Very confusing stuff, I opened up the silver box and checked out inside, nothing burnt or out of the ordinary.

My next move is to pull the solenoids out of the engine bay and confirm there operation.

Just thought I'd crack this up online and see if anyone has any thoughts or experiences with these units playing like this.

A few other things I've tried are:

Resetting the controller

Unplugging the blitz power meter (also usually connected)

Disconnected the actuator feed from the solenoid block to confirm turbo operation, turbo works fine.

Setting all channels to 1, nothing happened car still boosted as stock

Scramble has been turned off

Well that's about all I can think of for now, any help will be greatly appreciated.

Cheers!! :P

    • Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R. 
    • Thanks. We getting some parts along too so he will be solving the speed issue like next week so i will let you know what he came up with.   
    • 21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.
    • Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.
    • Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
