Questions About Dialing In Up A Boost Controller

[yoshiii335]

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?

No

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?

[GTSBoy]

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.

Ok

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.

[Ben C34]

Set it up to achieve 14psi.

You don't need a low boost setting.

[GTSBoy]

Agreed. I have high boost set to the max I want to run, low boost set up to something less than that and I don't use it.
