to be honest...the innovate lc-1 is suppose to be the best. IMO playback is cool, but i didnt see anywhere for actual logging...so i honestly dont think it will work well for tuning
i mean i have some pc software that can log several different parameters, you would just need the obd2 connection piece.
I agree except I don't have any experience with the LC-1, but about the part of needing the abillity to datalog to a laptop. The playback feature is pretty much worthless on the gauge if you don't know what rpm you are at. If you are just looking for a gauge to monitor A/F while driving, the Autometer will be fine, but if you have any need to tune via datalogging, I don't think the Autometer will work very well at it. I have this setup
http://www.zeitronix.com/order/order.htm with the black face round gauge, and it does not look out of place compared to me Autometer Cobalt boost gauge, but you will need a laptop to datalog. However, you would need one anyway to send datalogs to your tuner for adjustments. The Zeitronix has alot of inputs too. I have A/F reading, RPM signal, TPS signal, and have my MAP wired to one of the 0-5V sources for logging. Hemifever told me all of those should be good for him to tune my truck, and are pretty much needed to get a good tune.
BTW, for all the stuff I got, it was just shy of $400, which is a little more than the Autometer gauges, but it does so much more for the money.
