this thread is definately back from the dead. heres a few more random thoughts on it:D
no doubt histos & charts are WAY more useful for tuning , but I use the guages a lot since I commute to work 2 states away 6 days a week morning & evening for work.
I especially use a very big KR guage and a really big speedo that turns to red at 78 mph - comes in real handy since I dont use cruise often to keep the old speedo from creeping if you arent paying attention:doh:
pretty much have everything set to turn red if something is going wrong so you can see it without actually looking at the laptop.
I have thought of using the guage feature in a gutted car with the laptop front & center where the factory guage cluster was in a budget drag beater - so aside from all your other issues you face with the 39 I like that idea :cheers:
