    OEM is good for reliability on some parts, but not all.
    IMO, the brake rule is a completely different scenario than the ignition discussion.

    Sounds like it might be a MAF issue. I've had them go bad on the dyno and had the MAF end up being the culprit.

    What does the EECIV have for datalogging options? That's how I found the bad O2 on my truck and that's also the most certain way to diagnose a MAF. Does the pumpkin run a dry filter or an oiled filter?

    I think Mike is spot on in everything he has said. OE parts is not a goal, rather a tactic to achieve a goal of cars being safe, cheap, reliable, and good for competition. Sometimes OE wins, sometimes it doesn't. However, I do recognize that when the ignition rule was created, all aftermarket ignition coils, distributors, bla bla bla were more expensive than boring looking black OE replacements. If that is no longer the case and therefore the balance shifts...great, lets get the facts together using real data across the platforms and change the rules.

    I think the racer should have latitude to determine OEM or other parts when "performance" is not impacted. Reliability can also be time and money. No, I don't think a small block Ford guy should have to choose whether or not to inspect a crankshaft regularly versus a potentially more reliable, less expensive overall aftermarket. Should a 4th gen guy have to buy some unobtanium dash cover, just because?

    There were other external drivers that have since been removed so why not go back to OEM?

    I think the overall tone of the rules is still fine, but some of this stuff needs review.

    All drivers are free to go back to 12" rotors with twin piston sliding calipers any time they want.

    We dont have a MAF. We run a K&N oiled filter in the stock airbox.

    What about putting a volt meter on the TPS to make sure it's ramping correctly during tip-in.

    I thought you were using Cobra engine management? If not what kind of fuel pressure do you run? Was there a time when you didn't have the tip in hesitation?
