Those with 97 or 98 supras....what did you do to keep the "check engine" light from coming on after you installed the downpipe. I would like to keep it functional in order to detect problems.
I have already read the O2 simulator write-up on mkiv.com, but was wondering if there is another way that is better/easier.
Thanks,
