YRV Turbo MAP sensor and boost gauge

Forum: 

OK so i have located the MAP sensor underbonnet.

It sits underneath the intercooler, easy to spot with a vacuum/pressure line going to it and a 3 wire connection plug.

Tempted now to connect it up to a multimeter and raise boost to watch what voltage the ECU triggers the fuel cut.

Then i can make up a FCD and preset it to suit.

Not fitted a boost gauge yet though, Will probably fit one where the clock is, or air vent nearest the drivers window.

Fitted boost gauge this

Fitted boost gauge this evening, a single pod off the pillar.

Hose Tee'd into the MAP sensor line.

Boost seems to be a steady 9psi normally, with a occasional brief overboost to about 11psi when you initially floor it at lower revs.

Yep same here. Usually 9psi

Yep same here. Usually 9psi with, like you say, the occasional 11 psi if it's feeling generous.

lol, this is true I can

lol, this is true I can confirm...........but hard in 3rd is when my boost reaches its peak.
The fact it does 0-80 in 2nd gear is mental!

Ha yes they are very highly

Ha yes they are very highly geared,

Although peak power is about 6500rpm I think, so i don't rev it much over this, little point.

Quite like the boost response though from the small turbo, 2500-4500rpm good torque.

They don't sound as eager and happy at high revs as the GTti.
