I have a 12' civic si, with a k tuned downpipe with high flow cats. I failed the inspections in NJ, and was wondering whether the problem was due to the downpipe or if it was because of flashing the ecu with hondata. Any help would be greatly appreciated, thanks!
is it because your secondary o2 sensor is disabled? you may have to enable it, drive carefully and slowly to the inspection place, so the CEL doesn't come on. that's just my guess
I just went to get my car inspected In NJ and failed with my catted k tuned downpipe. My tuner looked at the data and everything is enabled but when fp hooked up to car with laptop, it says my cat and o2 sensor is not ready. What do I do?
Nope, my tuner asked the same thing, so I should drive it and push on it before heading to the dmv? He told me to push on it so the car can recognize that there is a cat., told me to try to drive 100 miles then go
Some have had trouble getting it to set regardless of mileage. If they don't set you will need to remove the dp and/or flash back to stock calibration.
Use your flashpro to view your obd readiness monitors. If any are not set or complete it means the ecu is still waiting for feedback to confirm the emissions equipment is functioning properly. Until then you cannot pass an emissions test.
So my obd2 diagnostics is saying it’s not complete, and under supported it says yes under o2 sensor, evaporative system and catalyst monitoring. All three are under incomplete. How do I change that thru flash pro?
If your tuner has already confirmed all sensors are enabled then you can either keep driving to see if they set. Or go back to a stock calibration to get through the inspection then flash back to you tune map.
If you calibration is not locked, you can check under misc tab.
I had a similar problem with my dv6 catted downpipe. What I did was first adjust the defoueler. I backed the nut off a bit to pull the 02 sensor away from the downpipe a little more. Second thing I did was go into flashpro and I "flashed ECU back to stock" flashing it back to stock probably wasn't necessary, I just wanted to be sure it would pass. If you're throwing a CEL, you should definitely try adjusting that defoueler though.
Also these cars have a specific process you "should" follow to get the monitors ready. I just drove the piss out of it for like an hour. But technically you're supposed to start the engine from a cold start, turn the AC and defroster on for 20 seconds at an idle. Then drive at 50-60mph for like 2 mins, let off gas to about 20mph, drive back to 50-60mph for another five minutes and then let off gas back to 20mph. I forgot the exact process, but I'm pretty sure it's something like that. That's considered one "drive cycle" sometimes your car might take 3 or more for the monitors to get ready.
Just keep checking the monitors in flashpro/whatever software you use. Once all of them are up, drive it very carefully to get inspected.
On my RV6, the cat was towards the tail end of the downpipe, so the second 02 sensor bung on the rv6 was pre-cat. I'm not sure if other brands are like this, but as it's a ots cat, my guess is they are.
From what I've read on these forums some had success with them, some without them. What could it hurt? They're fairly inexpensive. I tried it on my dv6 catted downpipe with and without. The car didn't throw any codes WITH the defoueler. I even had to adjust the defoueler out a bit just to prevent the cel.
Yep, unless you've got hondata, ktuner, or aftermarket ECU, you've got to have the defouler on the secondary o2 bung. These keep you from getting a c.e.l.. They are on Amazon pretty cheap. Sounds like if your a inspection state that these may not save you though.
I just looked at the ktuned site. They have proper cat placement and a spot for secondary o2 so there shouldn't be any issues there.
OP, have you actually looked under the car to make sure everything is installed properly?
While a defouler can't hurt, i wouldn't think it should be needed with the ktuned unit. I never had a defouler on my full race and never had a CEL...i have heard of needing a defouler with any aftermarket downpipe though.
