Ive done multiple searches, so far ive come up with: return to original back up, drive car and "ready" all your drive cycles, pass your smog-check then install custom tune back. BUT my prob is the car wont run steady enough with the upgraded cam on original back up. Im definitely not putting stock cam back in and all. Is there a way to write a tune that doesnt alter certain parameteres enough so as to allow my ECU to proceed to "ready" my (non existing)EGR drive cycle? Any info or options is much appreciated.
Thanks,

Cam Upgraded required custom tune, but my ECU now cannot "ready" the EGR drive cycle...

This is something you need to discuss with your tuner. Are you sure he hasn't disabled the EGR or made some changes that might keep it from operating properly?
Or are you saying you've removed the EGR system?

Re: Cam Upgraded required custom tune, but my ECU now cannot "ready" the EGR drive cycle...
Thanks for your response.
The car did not come with an EGR system. I believe ECU uses the vvt somehow to regulate the gases. Either way its beyond me why the EGR drive cycle is even listed to test. Was hoping you might have some insight from the tuning viewpoint on PIDs possibly would have anything to do with keeping the ecu from proceeding with the thest cycles? Without the tune the ecu proceeds to test the EGR even knowingly it does have an EGR. I'm puzzled knowing this because (it knows it doesnt have the EGR, But it "tests it", after the tune- all of a sudden it doesnt want to test it) what would make the ecu notice to "not test" it?
I'm still waiting for a response from my tuner. I just thought maybe I could run this by the forum to get any more info from anyone that could help.
Thanks again
