Curious to hear what you guys who are using the IQ3 did for a throttle and brake sensor. Would also be interested in where you sourced the sensors. TIA

Sean we have the Racepak sensors. The kit for throttle, brake and steering is expensive but as you know it is pretty well plug and play. If you are coming to the Mosport race you would be welcome to look at the sensors and data.

Plug 'n play. Don't reinvent the wheel. Use the RacePak sensors.

Sean F

thanks guys - where did you source them?

comatb

I bought mine directly form Racepak but there are dealers out there that might be able to shave the price a little.

The guys at racepak are very helpful and their forums section on the website is full of information. They take calls without issue to handle questions,

Is the Racepak brake sensor pressure or position? If a choice go pressure, much more informative IMO.

comatb

The Racepak is pressure.

Racepak sensors are the way to go. The throttle, brake and steering package are all VNet sensors. Using the Universal Sensor Module [USM] for under $200 you can use Racepaks non-VNet sensors and save quite a bit. Use their 0-1500psi pressure sensor for brake. The best TPS solution depends on your engine. 993 or later, or 944Turbo have a true tps sensor that you can tap directly. Earlier engines need a potentiometer on the throttle body shaft or similar setup.

I went with the USM and Racepak non-VNet sensors mainly because my 944 does not have ABS so I only needed to buy one pressure sensor. I recall paying under $1100 vs the full kit that was $1400+. I think if you want to monitor front and rear pressures independently the VNet sensor kit with two pressure sensors are the way to go.

Here is a pic of our throttle sensor mounting on our 944 n/a.

TPS and brake pressure setup only requires two sensors and the USM - 0-1500# $179, 0-3" linear $265, USM $199.
Once wired up [sensors to USM, USM via VNet cable to logger] its simple to select the appropriate sensors in DatalinkII and if you have an IQ3 to display the values on a second screen page. This is in the $500 range, and you have two spare channels in the USM for things like oil temp and pressure. Setting up warnings for low temp and high pressure is easy to do as well.

Can someone remind me what the software is for data and video with the IQ3?

comatb

I was talking about the kit that includes steering position as well. Sorry but I didn't mean to mislead anyone. That kit isn't listed on the Racepak price list anymore.

ProCoach

RaceLink II for the data.

Tony - how do you wire the sensors to the USM? You don't need a vnet cable for that?
