Recently visited the California (BAR) Bureau Of Automotive Repair State Ref to have the car tested to clear a citation for "modified emissions" that was marked as "correctable". The test is way more thorough than the usual CA smog check. To recap... I got cited for modified emissions, so the DHM turbo kit came off and OE intake, turbo, exhaust went back on, basically back to stock.... well almost.
So here are some random thoughts of the event that stand out in my mind.
The test was a bit nerve wracking mainly because everything on the car was scrutinized by 3 techs, I mean everything. Nothing was left unturned, they were as thorough as they could be with the skills and tools available to them. I was there observing the whole time mainly playing 'dumb', but was happy to answer any questions they had. They paid a lot of attention looking over the turbo and plumbing. I mean looking at it over and over and over. I was surprised that they took off the plastic engine cover, I thought they weren't supposed to remove anything from the car, but whatever I didn't have anything to hide under the cover. I was glad everything on the car was stock for the most part, including the sound symposer plumbing.
They noticed and asked me about the oil cooler, even though I knew it was legal and nothing to do with the emissions violation.
They made sure the OE catalytic converter was on the car, they asked if the intercooler was stock, I replied 'yes'. It wasn't until I left that I remembered I left the Airtec intercooler on. Fortunately any aftermarket factory fit front mount intercooler is hard to see.
They scrutinized the exhaust even though it was stock and I wasn't cited for a loud exhaust. I was glad I had the stock exhaust on the car for this test, because I almost left the Cobb cat back on there. They revved it while another tech was listening and if needed would have brought out the decibel meter for a reading. The Cobb cat back probably would have passed, but I didn't want to take a chance at least not for exhaust noise and have it fail for that. I was already taking a chance with something else, the tune on the ECU.
They made sure the check engine light was not on and working right, then they plugged into the OBDII port and looked to see if there were any alarms and to see if the I/M were in a state of 'readiness'. I was anticipating this so I completely removed the Accessport/Cables from the car and left them at home.
Once the car passed the visual and OBDII inspection they proceeded to put the car on the dyno to simulate on the road emissions and inserted an emissions probe into the tail pipe, which I wasn't really expecting since it was an OBDII car. The car was cited for emissions violation so they were going to put it through the gauntlet. During the test I could see the numbers and the car was emitting clean, very very clean.
Besides the car being overly scrutinized another nerve wracking part for me was I took a chance and took the car in with an Accessport tune loaded in the ECU, mainly out of my own curiosity and knowing that if it failed I'd have to correct the issue and return for another test all over again. I felt if I could get the car to pass for a State Ref test that I could also get it to pass for the regular CA Smog test when it was time and I really wanted to find out. Well... the car passed a CA State Ref Smog test with flying colors on a tune, lol !!!
The whole test took about an hour, easily 35 mins for the visual part alone. The certificate was $8.25. The citation was $25 to the court. I'm free and clear from this citation now and don't have to appear before the judge, until the next time, hopefully never again...
Whooo hoooo... emissions are clean, clean, clean.... with an Accessport tune loaded. Just the standard 91 octane out of the Shell station pump with 10% Etoh, Pennzoil Ultra 5w20, one step colder Denso plugs. I was too lazy to put the stock plugs back in, LOL.
