living in a non-emissions testing area(and state entirely, i think).... i don't have to worry about the EPA breathing down my neck about it.

occasionally, i see some 70MPH travel on the highways for long trips and have a ~550 mile round trip coming up VERY soon that i managed to squeeze 37.6MPG out of in a 1990 grand prix a year ago. i'm interested to see what i'll be able to do with this car on roughly the same route, preferably with some kind of improvements done before it happens.

depending on what level of control someone is looking for, you could use something as simple as an arduino with excellent results, assuming it wouldn't make the main PCM think the transmission is acting odd. some like to calculate TCC slip and other things based on what it assumes the gear the transmission is in, along with TCC status. if it goes outside of a boundry it likes, it can make the engine operate differently as well, shut certain things off or force others on.... i'll reread through that thread, i seem to remember skimming though it before.

according to that, .36 and 22.6, though i could have sworn the LS was a little less aggressive, like .33. the Z34 model got a front bumper with the air dam extending down a little further to catch more air. i'm not running a spoiler either.
