Data Loging/Acquisition

[LitemUp]

What are you guys using for data loging/acquisition for the AEM UEGO wideband A/F, and the Autometer Boost/Vacum digital meter? I want to start doing a bit of fine tuning as there are some small spot in the lower part of the rpm range that run lean while under vacum (cruising at low rpm)/very light accerlation.

This is what I have/use but doesn't do me much good since I can't make changes to the factory CPU.

I have the LM1 and AuxBox. http://www.innovatemotorsports.com/products/lm1.php I can record up to 40+ min of A/F data as well as numerous other parameters for reference. I've done TPS, RPM, Vac and acceleration rates. TPS and RPM tied with A/F is really all you need to get a good picture of A/F at any throttle position and RPM. Amazing how far off tuning really is from the factory.
