I wasn't sure where to ask this but hopefully this is the right place. I live in Washington State (Clark County more specifically), and need to go through emissions in a few weeks. The car is a 2000 GSR that is turbocharged and running a OBD I ecu. For the test I will be putting my stock injectors, map sensor, and OBD II ecu in. My question is how far do I need to drive before I can be tested. If I remember correctly there is a minimum distance that must be driven when the ECU is reset before they will pass you. If anyone can help me out that would be great, as I would like to drive as few of miles before testing as possible.

Thanks

 

There is no such log on an obd2a/b honda ecu system (if memory serves correctly).
You should be able to plug the ecu in & drive it directly to inspection.

 

ok thanks mtber, that would make things easier, as I am using the non fouler trick for the 2nd O2 sensor and I dont want to risk throwing a code by driving any extra distance

 

What you're referring to is the "not ready" situation with OBD2 ECUs. Honda ECU's get ready quite fast compared to like Nissan or Mercedes. Basically whenever you reset the ECU, it has to run through all of it's on board diagnostic tests to confirm that all sensors are working right, the cat is doing it's job, evap system is good, etc etc. Each of these tests have weird requirements. The evap test for instance in most cars requires that you drive for a period of time and then let the car sit for a period of hours. That way the ECU can measure the expansion of the gas in the tank. Other tests require you to drive for a specific amount of time within a specific MPH range, stop for several minutes, speed up rapidly and then decelerate for a certain period of time. I have the book at my work that describes these drive cycles and some are pretty funny to read. Unless we are purposely getting a car ready on the dyno for a customer, we usually just tell them to keep driving the car and come back in a couple of days for a free retest.

Anyway, you can check the ready status with an OBD2 scanner. Most states allow you 1 or 2 not ready's and you can still pass the test. But basically if you have too many not ready's, you just need to drive the car around town and on the freeway for about 50 miles, let it sit overnight, then check it again the next day. There is no true "minimum distance" to drive the car. Some tests can be affected by weather conditions. Some will never get ready if you drive ONLY freeway or ONLY street and not both. But it's a Honda (Acura) so it wont give you too much trouble.
