Hi guys,

Getting my car tuned late next week, and so far its just ya 33gtst with "basic mods" using a turbosmart single stage boost controller (flick between standard 7 and its meant to be set to 10psi but spikes 50% of the time!) and Im thinking - should I ditch the turbosmart b/c and go back to the normal solonoid to prevent the thing from spiking and causing issues, or as its being tuned (2-3 day tune) will it be alright?

At the moment the car is running like crap and I just cant wait for the tune to stop all these bugs.

But my main concern is boost. is 7psi stock going to be sufficient? Or should I use the turbosmart b/c and just keep it at the one setting?

Or somehow rob a bank and buy an EBC for minimum 500?

Cheers guys,

Chris

You want EBC-- those profec spec B's are 390 to your door step!! look in trader section!!

Otherwise see what the tuner says!! Buy another cheap bleed value and if there any issues with your turbosmart while tuning, ask your tuner to use the new bleed value and see if that works..

If its still spiking, get a ebc..

But see what your tuner says first..

I got my eboost 1 for $550 brand new. U might be able to get one cheaper second hand or off ebay. Its got 3 boost settings which is perfect since my cars main priority is road use, but the 3 preset settings u can jump between at the press of a button makes its easy if u wanna really give it a boot or take it to the drags. I've got mine set at 8 - 10 and 14 psi. I cant see the point of spending the extra money and getting an eboost 2 with the 8 boost settings unless your cars just for drag racing since its got all that extra jazz in there to take care of that kind of stuff.

it will take a week to confirm a purchase and transfer the money, especially with a weekend in between. you are gonna have to get something local champ. perhaps loan a good working bleed valve from someone until your nengun purchase comes in?!

If you aren't running too much boost, it probably is best just replacing your bleeder.

I'm on 12psi and PowerFC.

It fluctuates but i can't tell from the driver seat.

Here's the curve......

why dont you go with the turbotech bleed valve ($22), and set your desired boost using a boost guage. then the tune will be right for your boost setting, and you can use whichever boost controller you want later, just set it at the same boost level.

Dont be rushed into a EBC just because of your tune next week. Get a turbotech for now and worry about your EBC later. EBC's cost quite a bit so you don’t wont to be rushed into a decision solely based on delivery times.

I have a spare turbotech if you wanna borrow it for a month or so as I have recently upgraded to an greddy e-01 so I can pull the chics like Paul Walker. PM me if you wanna borrow it

Hey Chris!

You will not get the benefit of the electronic type!!

Save your money. The $20 one works fine for up to about 12psi or more.

Or even a small orifice piece that you replace your solenoid with will give you steady 10psi (If the right size bypass hole). It's bypasses enough air to maintain 10psi..

Only when you upgrade the turbo consider a more elaborate boost controller.

I already had the Power Fc installed so all that was needed was to get an electronic solenoid hook it up to the standard solenoid plug then attach the signal & actuator hoses.

Then attach a MAP(3bar) sensor to the input on the power fc.

Haltech sell the solenoids for about $120

Then dial in your levels on the hand controller duty cycle & pressure.

& make sure u have the correct cable/loom

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.
