New to the forum, just bought my Tuxedo Black ST last week, and although I am more than happy with the equipment in my FiST, wondering why no boost gauge in the car...

What solutions are you guys using to show Boost pressure? Anything I could plug my iPhone to possibly?

Also, what options are available for Oil Temp? Pressure? Air/Fuel?

Thanks, Dan

I'm using a ScanGauge. The latest version allows you to use the Manifold Absolute Pressure gauge as vacuum/boost gauge. You can also use an Ultragauge, or go all in with the Cobb AccessPort which allows engine tuning and gauges. There are also WiFi OBDII scanners that you can use with your phone.

Do you by chance know the name of an OBD II app that I could purchase for my phone? I am guessing that I will need some sort of wire to connect the phone to the port as well? (I am used to tuning a 1988 Toyota Supra with a OBD I port)

There's one called Rev that works on the iPhone with the WiFi OBDII scanner. There is a popular app called Torque that was developed for Android, but I'm not sure if it's available for iPhone. (Sorry, I don't have an iPhone so I can't give recommendations on apps)

I too would have liked to see them added.
However I am sure that the main reason these gauges were not included was cost.
All of these functions are controlled by the ECU and are not adjustable, therefor these gauges are not necessary to average consumer.
If you plan to do your own tuning then you could add these to your car.

Cobb could answer how the tune would affect boost. The way I read it, if the tune just alters the torque targets in the engine parameters (which sounds like a big part of what the Cobb changes), then the tune is legal for Stx. Cobb sounds pretty responsive to customer feedback. They may be able to confirm this, or even come up with a class legal tune.

In Street (was Stock) class, no tune is permitted.

Technically we do not adjust Boost Pressure, we adjust the Turbo Inlet Pressure (TIP) which is pre-throttle. In the case of the FiST, we lower the maximum TIP the car can achieve by 1psiA compared to stock. We also increase the torque caps on 1st and 2nd gear which will allow the car to achieve more load and boost in each of those gears. I'm not sure how the rule book for STX treats these types of changes, so you'll want to check with your SCCA class for more clarity.

From the 2014 SCCA rules draft A:
The engine management system parameters and operation may be modified only via the methods listed below. These allowances also apply to forced induction cars, except that no changes to standard boost levels, intercoolers, or boost controls are permitted. Boost changes indirectly resulting from allowed modifications are permissible but directly altering or modifying the boost or turbo controls, either mechanically or electronically, is strictly prohibited. Traction control parameters may not be altered. Any OE OBD2 or newer communications port functionality must remain. The Check Engine Light (CEL) or Malfunction Indicator Light (MIL) may be disabled via software.
Alternate software maps which violate these restrictions may not be present during competition, regardless of activation. Only OE sensors may be used for engine management.[/
Sounds like it's legal for STX since they are not directly changing boost controls.

Seriously, you guys are knocking it out of the park with responsiveness on these boards. I am running Street class where the tune isn't legal, but I kinda want to buy an AP just to support you. Keep up the great work.
