This new multi-function unit is a great tool for all horsepower enthusiast that are upgrading their engine with Turbo or Supercharger.

Chris, have you decided on what gauge you are going to install? MPI highly recommends Pro-logger but i like the size and cost of the Koso x2, wish we could get some info on it. What are your thoughts?

I put the Koso boost gauge on my sled last season and it works well. I wish I would have seen/known about this one. I may upgrade this winter.

I think i will do the same. Are you changing your pulley's on your S/C?
I was never lacking for power last year so I see no reason to fiddle with it.

Right now I am waiting for a reply back from Evolution Motorsports about the ECU upgrade.

That is my #1 priority for the sled before the season begins.
They are at HayDays so I am on hold till next week for the monthly Update.

On my MPI turbo it looks like it was pretty easy - to get the boost measurement they just spliced into the boost line that goes to the GEMS box using a t-connection. That "boost" line runs up to the little black KOSO box that has the sensor (they mounted that to the black plastic radiator shroud) - the wires then run from that up to the gauge (sits to the left of the stock yamaha gauges).

Make sense?

Could you post a picture?

I would like to see how your gauge is mounted and where the wires go if possible. I am going to be installing a MPI 180 Turbo and want to install koso x2 gauge. I have no clue how they hook up.

OK I went out and snapped a few pics -

This first one shows the KOSO sensor that they mounted to the plastic radiator shroud. The blue line is coming from the "T" in the line that runs to the GEMS Box - measures the boost. The black line is the wires that run up to the gauge.

This picture shows the "T" that they used

Picture from above that shows the gauge mounted and the sensor below it.

Looks good thanks. How many lbs of boost you running? how do you like the kit?

8-9 on my last ride if I remember right - I cleared the memory on the gauge, otherwise I could give you an exact number :)

I really like the kit so far - there is a slight burble once in a while but I can't nail down the exact RPM or condition when it happens (not consistent). The biggest issue I had last winter was the short season - I need to get some more miles on it!
