Data Acquisition

Any of you guys hooked up an AIM Solo DL, EVO4 or similar data acquisition system through OBD connections from the LS1 PCM? Obviously the 944's are too old for this, but I was curious if the LS1 PCM makes this possible with the swap, and if so, what parameters are available, and how it's wired.

One of the Corvette forums might be your best resource for this. If not there, you could try the NASA or SCCA racers' forums where the LSx drivers go for technical info. LS1 Tech might also be a resource.

I have not used the AIM SOLO DL, but I do know that it simply hooks up to the existing OBD2 plug and gets 12v power from a lighter socket. Nothing fancy about it. If you want to check what parameters are available, an easy way is with a cheap bluetooth or wifi ELM327 adapter (check on Amazon or Ebay) and either the included software or one of the numerous smartphone apps. I've use Torque on an Android tablet. Should be able to at least get RPM and throttle position (%).

The best I-phone app (this month) is Lemur Blue Driver. It’s a free app and their OBD2 blue tooth interface is $99. It’s a pretty good scanner, view and clear codes, repair reports, freeze frame as well as real time status monitoring. You can select the parameters you want but I’m not sure how many it will do at the same time. You should be able to display any parameter the PCM can process that you’ve sent a sensor signal to. In some cases like engine oil pressure, you’d probably have to send a VDO sensor signal to the dash and a GM signal to the PCM. Shouldn’t be too hard to do whatever you want if you had a GM harness with all the sensor connectors and a place to install the sensors.
