So how is the 7g civic comparing with the previous g's?

just chillin said:

...the differences between 1, 2, and 3 is that each one adds more sensors to monitor emissions, so for example if your exhaust causes more emissions to exit the car the ecu will do something to counter that. that's why mods add so little hp on these civics. also the 00-01 gsr's are the same way; for example the greddy turbo kit designed for the 3gen gsr's doesn't work on 00-01 cause of that obd3 crap.

I was going to keep quiet, but this is getting silly. What the hell are you rambling about?

First of all, as early as 1980, numerous vehicles were using electronics and on-board computers to control many of the engine's control systems, such as fuel and ignition. Vehicle manufacturers had to develop ways to diagnose problems generated by the electronic hardware found under the hood. Thus, the first OBD systems were developed as electronic systems replaced mechanical systems. Is this what you want to go back to; a mish-mash of electro-mechanical controls???

Secondly, OBD II is different from OBD I only in that OBD II is strictly emissions oriented; it will illuminate the CEL whenever it detects a component/system malfunction that could cause emissions to exceed 1.5 times the federal test procedure standards.

Thirdly, OBD III hasn't been implemented yet, and probably never will be. Why? There seems to be some question as to the "suspicionless mass surveillance" of private property. There is no opportunity to confront or rebut the results with OBD III; no notice that the vehicle will be tested. Fourth Amendment search and seizure issues tend to arise.

Read what Michael McCarthy of CARB had to say about a recent OBD III prototype:

“We paid a contractor to build up a couple of mock cars with remote transmitting systems and demonstrate that it was technically feasible to have a system that sends out a remote transmittal when the check engine light comes on,” said McCarthy. “A pretty basic contract since there are already systems like On-Star and LoJack.”

“The concept is to stop requiring smog checks for every passing car and only test the failing cars. It would likely be a voluntary system - when you buy the car you could choose whether to go to smog check every two years or pay $xxx and never have to go to smog check,” said McCarthy. “You would, however, have to push a button on the dash once every three months that would send a signal that identifies your vehicle and the status of the check engine light. If you forgot to push the button you would probably get a letter in the mail telling you to press it or bring it in for inspection. If you pressed the button while the MIL [CEL] was on, you would probably get a letter in the mail saying you have 60 days [yeah right!] to correct the problem and press the button again. If the MIL [CEL] came on and you got it fixed before you pressed the button, you would never get any notice in the mail. There would not be a continuous signal identifying the location of the car or anything like that.”

This OBD III prototype system was built by GM Hughes Electronics, and uses a roadside transmitter to interrogate vehicles as they pass by. The system is reportedly capable of retrieving information from eight lanes of bumper-to-bumper traffic whizzing by at speeds up to 100-MPH.

Several issues surround the OBD III concept. From a regulatory perspective, all of the technologies used, other than roadside technology, require a Federal Communications Commission [FCC] license. The possibility of interference with other signals in the same band is of concern. The issues of commercial operators, law enforcement, jurisdiction among state agencies, Intelligent Vehicle Highway Systems, et cetera, have to be addressed before OBD III is a reality.

We're light-years away from OBD III. How about getting your facts straight next time...
