hi guys,

just wondering once you fit a manual boost controller on the rb25det, do you have 2 block the factory boost soleniod or d/conect it or do you leave it just open, because one vacum line gets pulled of to go into the new boost control?

you can leave the top one hooked up as it only runs to the intake. if you take the solenoid off then make sure you block it up. the bottom one that comes from the wastegate hose can be left open, but it may get crap in it, so it is best to block it off. you can either screw a screw into it, or just kink it and use a zip tie to hold it kinked.

thanks dude,

on my soleniod both are really just open because i have venting bov so first hose is open and then the bottom one thats goes back into the intake is also open because i have a s/steel intake pipe of the turbo to the afm,

would this cause aqny boost crep or spike of anysort, im getting a bit of a flat spot just in 2nd gear from bout 3500-4500rpm

      R34 GTT RB rough idle problem with weird RPM gauge fluctuations

      Throwing my spoon to the soup here a bit.  When I installed a 044 back in 2012, along with the direct power mod, the car became very difficult to start. To a point I burned one starter motor as I was late for work and tried to get the thing going. With some tuning and careful use of gas pedal when cranking it became bearable. Trying to make this short as possible, but the 044 died after 2-3 years, after which I went with an AEM 320lph pump, which also died after about 4 years to my dismay. After that I went with a Nismo pump, and while trying diagnose an emissions problem, I noticed for the first time that my fuel pressure was 5bar/72psi on idle, and that removing the vacuum line did nothing. After monitoring the situation, and removing the direct power feed and going back to FPCM in attempts to remedy it, I noticed there was fuel in the pressure regulator vac line. Kept the FPCM, installed AEM external regu and the car became sooo much better in every way, including starting. And I had driven it like it was for 11 years.. Anyway, I agree these are likely two different problems, and the FP problem you just haven't noticed before. I do not know much about haltecs, but what first came to mind was the CAS, which probably is not there any more. So how is the wiring from haltec to gauge cluster? How is the battery voltage and alternator?

      Your car was auto before? You have different diff ratio (auto vs manual i think? or n/a and turbo?)

      +1 for getting a screen off alibaba, CarPlay/Android Auto is vastly better than whatever navigation cars had 10 years ago. I got an Android screen for my 2015 BMW, huge difference. Fully compatible with factory stuff including iDrive controls.
