hey guys ive tried again at setting up a turbosmart electric manual boost controller with yet again another huge result of NOTHING...im starting to get annoyed because of how simple it all seems and yet getting no where..ive seen this exact setup done on another R33 and it worked...so im starting to think my wastegate is rooted or something...have a look and let me know whats going on please =] Cheers! (car is boosting over 10psi no matter what, i want it back to somewhere between 5>8 as it doesnt seem to appreciate 10..)

Hmmm, hard to tell dude! From the pic, and from my knowledge after having installed my boost controller just today. It looks like ur boost controller isn't going to do anything because of the way u have it wired. The vac/boost line is all linked. U are not controlling the boost at all like that. Does ur boost controller have 1, 2 or 3 hole for a vac tube?

ok guys this is a pic of another engine ive seen hooked up in this set up and im asuming it works? its exactly what ive done except im using an electric manual verson of the turbosmart range tapped into the line thats spose to be there for the charcoal canister. im going to Kyp performance today to see what they can do, ideally i think all i need to do is drill and tap into my cooler piping and fit a boost/vacumme nipple and run it off that as the stock turbo doesnt come with a boost pressure nipple at the outlet side like most aftermarket turbo's do which would be ideal

For that boost controller you have it hooked up "correctly"

Although, I HIGHLY recommend taking your pressure source from an intercooler pipe, or off the manifold direct.

Secondly, if when hooked up direct from intercooler pipe to actuator you're getting over 10PSi, adding a boost controller won't bring it down... Boost controllers only increase the pressure.

Where are you located mate?

I reckon by T'ing into the carbon canister you have effectively added another boost tap to your actuator line which is actually a large chamber.. try a dedicated pressure source from the manifold or cooler piping.

The setup you are trying to emulate has no carbon canister, he is just using the old line to the CC as his pressure source.

Had a look at it today and from what ive seen its hooked up ok exept the vacuum point, also he's running a pod and FMIC. I told him that these things will increase boost and 10 psi is possibly going to be the lowest he's gunna get. I may be wrong? i think he' going to try change the vacuum point to see if that helps to

He can go as low as 3PSi if he's got the stock actuator.

It's all about where you measure boost, and where you take the actuator pressure source from.

Both from the same place, what the guage reads the actuator sees, 3PSi will get it open and holding steady.

I run mine from the manifold, as I want my pressure control to be in reference to what I'm putting down it's throat...

Thats a dumb idea - you really want your reference from just before the throttle body in most applications.

It's not a dumb idea.

Alot of big HP cars do it... It gives one huge advantage too... When you shift, the wastegate is sucked hard shut making ALL exhaust gasses head out the wastegate... :rofl:

I run my car with no BOV, so if I were to shift, the waste gate is held open, just as is on all cars that run their pressure source from the IC piping as they either run no BOV (And wastegate still sees pressure) or they run a BOV and as such, there is a delay in having the BOV vent, hence there is always a minor amount of pressure... At the least, they see vacuum...

As for claiming it's a dumb idea, you give no reasoning for it...

I see what you saying but - I think you would find alot more response with a proper BOV and the boost reference where I said.

It also becomes a vacuum leak when using a bleed style boost controller.

      R34 Skyline climate control unit transistor

      perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML

      Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

      Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
