Opinions Re Data Systems

[JEDD]

Does anyone mind sharing opinions regarding the current data system options? I believe most people use an AIM product in Spec Boxster racing but am not sure if this is true and, if so, which one(s). I would like to be able to share / exchange data with others. Also, I have heard that the ECU in the 97-99 Boxsters do not provide much information, so additional sensors are necessary. Does anyone have thoughts on which sensors are the most important.

Thanks in advance and I apologize if this has been covered before. I did not find much recent information in my search.

I use the Racelogic VBox HD2 in a 99 SPB and love it. I have a microinput module set up to get throttle, steering angle and brake pressure (estimated using brake light signal and longitudinal G). I think it is the best system all around, but not too many people use the system in SPB, at least not here on the East Coast.

Racelogic VBOX lite, fantastic unit, easy to use, less expensive than the HD. Video quality is not that of the HD, but I'm more interested in the data that showing nice vids and price point was a factor for me. I also have the microinput module and can get all the data that I'm really interested in easily.

Great information. Thank you very much!

JEDD,

What are your primary goals for a data system. Are you after great videos, driver development, chassis development or just monitoring your car vitals. How much $$$ are you willing to lay out.

AIM is popular because it offers many of the features of Pro systems (Motec, Pi/Cosworth, Bosch, etc.) at significantly lower cost. The VBOX systems have significantly better video capture and functionality than AIM.

There are pro's and con's to them all.

The K-line output from the Boxster ECU is far too slow to really capture meaningful data. It has many of the right channels. TPS for instance would not even remotely show you accurately where you were full throttle on corner exit. That why additional sensors are the way to go, or taping the signal from the TPS in this case.

Thanks Max and great information! I'll do some more research on those options.

My highest priority is driver development, then chassis development, vitals and video quality.

I don't want to spend too much, but I also don't want to throw good money into a system that doesn't advance my goals. Does this change anything in your opinion?

My experience with Aim is this exact thing. My speedometer show one thing on track and on replay is often 5 MPH lower Tack is similar. So you never see your peek speed on video. and my gas pedal was often 40 to 60 % when I know it was matted.
