Hello

I am installing a HKS EVC VI into my R32 GTS-T car.

Everything is just about hooked up.

The boost controller has the option of having the throttle control and rpm settings work with the boost control settings.

This envoles splicing into the computer harness.

Is it worth having the throttle control and rpm settings to be able to work with the boost controller setting?

Do you want it set that way?

The fact you are asking to me means you don't need it

Doesn't the throttle control boost anyway?

It allows you to set the boost setting based on what the throttle position is.

Does this give better performance vs just setting the boost level?

You also don't have a measurable TPS that you could use on an R32. The ECU's TPS on an R32 is only closed and open switch - not variable resistance to show opening %. There is a second TPS on auto R32s for the TCU. On manuals it is not wired to anything.

You could monitor the revs easily enough. There is a tacho output from the ECU which is easy enough to tap into. Setting up rev dependent boost levels is a bit of a pain in the arse though. The only useful reason you'd do it is if you were also monitoring vehicle speed and using it to give gear dependent boost (ie lower boost in 1st).

ok

TPS is Throttle Position Switch?

So not worth connecting those wires than?

TPS is either Throttle Position Switch (in an R32) or Throttle Position Sensor (in cars that have a variable resistance output, like R33 onwards, and many other cars).

If you have the unused auto TPS(ensor) on your car, you could hook it up, but you'd probably need to get 5V to it because I don't think they're powered up on the manuals at all, and it all starts to sound like a pain in the arse and I just wouldn't bother.

Thanks

Can anyone offer some boost settings suggestions please? I know max I can boost the stock turbo is 14psi, so how should I set it up? If I leave the boost controller in basic mode I can set low and high boost.

The car is a daily driver and I drive through traffic lots coming and going to work. I use the highways on the weekends. But I want to be quick on the street and on the highway.

      No chop chop of anything mate, it is what it is, plus, I don't want any air that isn't either going through the cooling stack or intake getting into the engine compartment increasing under bonnet pressure  Yeah, the Mazda Speed aftermarket intake above is less than ideal for multiple reasons, the requirement to remove the bumper every time you need to service the filter, and also smaller in diameter than the NC1 OEM one Weirdly, Mazda Speed is part of the Mazda motorsport division, "form over function" and $$$$$ for Mazda from unsuspecting punters I suspect  After some googling about them it seems they added no power, but do increase some induction noise Meh In other news, the electricians have been busy today at the house, and are back tomorrow finishing up all the security stuff and exterior lighting, they also added some lighting on the garage ceiling, which will come in handy when working in the garage when it's not freezing out there My Birdies raised garden bed also arrived today as well, which I'll put together and place tomorrow, it's a big tall Bessie, 74cm high, 92cm wide and 214cm long, this will come in handy as I am starting to get "stockpiles" of good soils from doing landscaping, some of the clean rock, namely the river stone, will go into the bottom of the bed for drainage, as well as the old Apricot tree that was out the back,  and when it's full, I'll grab another one, I will be growing enough veggies to keep me both busy as well as supplementing the shopping list I'm also awaiting another quote for a new Colourbond front fence, as the "1980 style cemented in rock edging" that was there and "fashionable at the time" looked arse, and my god, the amount of cement used to fix the rock was insane, it took 1.5 days for me to break out 12 meters of the stuff by hand, trim the bushes back to the fence line and dump it out the back of the joint to deal with at a later date,I will soon need a skip bin to tip it all Unfortunately they did alot of the cemented in rock around the joint, which I hate, so a few pallets of retaining wall blocks for around the front and back where the cemented in rock is will be required to bring it up to a standard, and look, that I will be happy with 12 meters worth of rock and cement Finished smashing the fence line and ready for a fence to be installed, yes, the lawns need some TLC and thickness, the previous owner trimmed the grass to the roots 😢, the TLC I can provide, and nature over time will do the rest And there's probably about another 40 meters worth of this landscaping abomination left to do around the front and back gardens, I'm guessing maybe 3 or 4 tons worth, tip fees for this will be a killer Meh, all in all I'm having fun and keeping busy, plus, it's good PT

      Just cut the bottom of the guard out. It's no longer got a big duct, to a sealed box, or a restriction. It has all the cold air from outside. Also, that cai you showed looks terrible. Bends are NOT good for go gos!

      Like I said, "black magic" LOL In the end,  it is what it is, and hopefully, what this here knuckle head has done is an improvement and not a hindrance Not that I actually notice any negatives now, or that I will get any seat of the pants benefits when all is said and done, but best practice says I shouldn't be pulling intake air from the hot engine bay  Famous last words: I cannot see it being any worse than what it is at the moment 🤔

      If the gases flowing in those two tracts had the same properties, you could maybe use such broscience. But the exhaust has a different composition, different normal density, different actual density (because of different normal density, and mostly because of the massively higher temperature), and different viscosity (again because of much higher temperature). Consequently, all of the fluid dynamics parameters that matter, that you calculate from these inputs, such as the Reynolds number, friction factors (for wall friction) and so on, are all incomparable.
