Due for OBD-ii E-test. Cammed car - any issues?
This will be my first e-test for ANY toy I've had - up here, once you reach 7 years old, time to go every two years. (Friggen cash grab!!) My mechanic buddy tells me I should be good as battery has not been disconnected and have never had a code since the heads/cam/intake mod almost 2 years ago. I have heads, mild cam, intake/tune but full stock exhaust including cats.

Whether or not a "cammed" car can pass emissions depends on what State test you're trying to pass, how radical the cam is and how well the closed loop part of your "tune" was done.
Also, some States now require all readiness flags set and sometimes it's hard to get engines with aftermarket cals and aftermarket low temp thermostats to set all the flags.
You need a scan tester which will read readiness flags. Then you need the Service Manual for it's drive cycle which will force all the readiness tests to run and set. You drive the car exactly as the drive cycle information says while watching your scanner to see if all the flags set. Once you see they're all set, then you go Smog Test.
For the member who was asking about a Smog test station in the L.A. Area which really knows its, stuff try Quality Auto Service in Pomona. Ask for Mike Garibay and tell him Hib Halverson sent you in. 909-596-5502. I haven't seen Mike since I move out of the greater L.A. area in 2012, but he always did my Smog work and seriously understands the whole Smog Check system.

"RedZ4me" to better understand how these things work, you need to look up in the Factory Service Manual to see what DTC tests must run for each flag to set. Then if you have HPT, download your existing cal and save it then save as, give it a new name, then you go into the new cal select engine diag., select DTCs, find those codes, leave the SES box checked, but set the "error mode" to "no error reported".
Do that right and your readiness flags will set to "yes"
After you are though doing that for whatever diagnostic or education purposes you have, put the previous cal back in the ECM.
