I took off my catted h-pipe and american thunder flowmasters and replaced it with a o/r x-pipe and 10series flowmaster I expected my check engine light to come on, but it didn't. Does my diablotuner have something to do with this? Will I pass inspection next year?

 

I think you have to complete a drive cycle before it realizes the change

 

My light took about 300-400 miles before it came on after I put my o/r pipe on. It will come on eventually.

 

I already had a 3 1/2 hour drive back to school, pretty sure ive put about 300+miles on the setup. Its going on 2months since I installed it. I guess time will tell.

 

You would have had a selection on your handheld for your O2's

 

yea I remember seeing that on my tuner but just put the stock tune from diablo on. didnt really modify anything but my gear ratio.

 

Then like said above it needs to cycle through in order to create a code... If it hasn'tcame on yet and it's not turned off then it's just a matter of time... It doesn't affect anything just an anoying light

 

+1 that annoying light. Mine has been on for months now. Im just too lazy to order MIL eliminators, let alone get under there and put em on.

 

Mine goes on and off whenever it feels like it. Sometimes it will be on for weeks, others for only 5 min. But i think that just means my eliminators are going..

 

bump......posted this about about a month agonow. Just finished another 6hour road trip on my setup that plus the daily driving ive none since and still no light. Id check my tuner to see if its turned off but Ileft it in Houston andIm back at school. I know its nothing special just a light but Im just thinking about it for future inspections(not due till July) because from what I understand in Texas they just check to see if the check engine light is on. Anybody experience anything similiar? or know if the stock diablo predator tune turns this light off?
