RaceCapture/Pro2 installed in 818 project/track car

[mikebr75]

Greetings!

I just acquired a RaceCapture/Pro 2 (thanks Santa… or wife) for use in a Factory Five Racing 818 car I have been building. The goal is to get the car completed and to the track in the spring of 2016, and adding the datalogger is a nice touch.

The 818 is a Subaru powered, rear drive tube frame & composite body car that is assembled by the owner (normally). I (we’ve – my father in law and myself) have been working on this project since May 2014. We have a bastardized EJ205 from the donor with nearly 200K on the ODO! but when tested it was at 155-160 compression across all 4 cylinders. Likewise the transmission was checked by our shop when we installed a LSD, and everything was said to be in ‘good shape’.

The engine has been rebuilt with new oil and water pumps, a simplified cooling loop, replacement throttle body, upgraded intercooler, a VF39 turbo and long header intake from an older JDM STI. At the dyno tune it made 225 HP @ 18lbs boost at redline, with 140 MPH indicated. We did encounter some issues with the intake temperature, timing & advance and oil temperature & pressure. Some additional work has been done to address these points (oil cooler, remote filter, and more air handling on the IC).

So, that brings me to today:

The RaceCapture/Pro 2 has been installed behind the dash close but not exactly centered in the car. I had also considered installing under the seat, but dash is easier to wire; maybe later I could relocate it to the floor of the center tunnel later. The Bluetooth transceiver is attached under the logger to the shelf.

I’ve run the 12v from a 6 position accessory fuse box in the passenger foot-well area. I’ll run a second line from that fuse box for hard wire an el-cheap-o Kindle Fire tablet next.

I’ve tapped the 3 existing sensors/gauges I had installed: boost/manifold pressure, oil temperature, oil pressure. I am working to insure these work properly now that they’ve been added as analog inputs to the RaceCapture/Pro 2 while keeping the dedicated gauges on the dash.

I have added 2 500 PSI pressure transducers I have Tee’d off the dual brake master cylinders. It will be interesting to see brake pressure & bias front to rear.

Because the logger will be behind the dash I’ve added a latching Vandal switch to my switch panel that connects to the first digital I/O port on the logger. This has been scripted to start/stop the logging function. I’ll also add a microSD extension cable from the logger to the switch panel so I can easily access the memory card.

The GPS antenna will (eventually) be mounted to the roof.

I need to wait until about June of ‘16 for the OBD-II bridge connector to be released so I can poll the ECU.
After completing the burn in test I can start thinking about some more functions using the Logger CPU.

Nice project! I actually put a deposit on an 818 when it was introduced, but went a different direction while I was waiting for the kit. Keep us posted on your progress.

Absolutely! Thanks.

Going to be slow over the winter while I wait for the hard-top to be delivered at the end of Jan. After that I plan to have the car registered and ready for track sessions by the spring; then I will try to drive the wheels off it.
