Hey!! Ive just installed a GFB Manual boost controller and a boost guage on my s1 stagea... but no real difference.

the boost gauge wont read over 0.4 bar even when i turn the boost right up and the boost i can hardly tell if theres even a difference.

ive checked to see if the MBC is bleeding off air as ive blown through it, ive replaced the pipe from the intercooler to the bleed valve to remove the factory restrictor and checked to make sure the side from the bleed valve to the has no restrictor. the pipe that can affect the air/fuel ratios ive put a screw in.

When i unscrewed the bleed valve when i blew in it, it took bout 4 full screw before i felt the air release throght the side, i then refitted the valve at this setting and tried it again to see if i jus hadnt turned it enough ... still no change so i unwound it a lil more and still no change ????

Ive connected the clear pipe from the gauge to the back off the intake plenum (stock place for factory boost guages on skylines) .

Can anyone post pics of how theres looks or offer any other advice as this is meant to be a 5 min install and ive been playing with it for almost a week now :lol: haha

cheers Lee

    • For fuelling the Haltechs have O2WB fuel controllers. Very useful for helping tuning VE and correcting for *small* mistakes. Of course if your injector/cam/trigger/sensor data is just wrong (or for a GTT which is not a GT) then you will get impossible reactions to things. I am sure you know this already but the reason people don't typically put haltechs (or any Aftermarket ECU) on GT's is because there's practically no real gains to be had - So this knowledge won't be commonplace.
    • Can someone tell me if the cracks seen in the rear sway bar bushings in these photo's is unacceptable from a roadworthy point of view?  
    • Shouldn't need a "base map" for anything other than guidance to ignition tuning. You just need the engine capacity right, the injector size right, and something, almost anything, for a VE map. On an NA engine, fuelling is almost completely a function of load signal & rpm. It should run and drive with a completely flat fuel map. It will be too lean under load, but that's easily fixed. We used to tune all ECUs without any base map. There were no such things (until someone had tuned a near stock engine on one, and then they had a "base map".
    • What did you actually buy/how much did it cost? When I got mine in like.. 2017...? 2019? the aim was to run Torque for gauges via ODB2 and things like Track Addict/Laptimers/Dashcam/Reversecam/Spotify etc. Mine never broke, but I wonder if you've got the same needs (it sounds like it). Cause I liked the idea of being able to do anything with it. That said, yours also cost 3x the cost of what I spent so... food for thought.  
    • For me there is a massive difference in manufacturer or big brand crippled android (Sony, Kenwood etc) vs the sort of thing I've installed here, which is basically just a tablet in DIN form factor with open Android, and the other model of course is mirroring - Android Auto/Carplay. I hate the locked down manufacturer and AA options where they decide what apps I'm allowed to install, including the Launcher but also importantly things like Ecutek (for this car) or Real Dash (Stagea) are not supported. Plus those crippled versions tend to be slower due to both overheads and lower spec hardware. On the other hand, when this breaks I'll likely be in trouble for support....but how is that different to owning an Infiniti anyway
