well, he took it to the shop...everything's fine on the computer...the adjusted the idle a little because the MAF was pegged out pretty much...it was running lean @ idle...and everything looked good...and then on the drive back to work, the CEL came on again.
one thing is for certain, the standard ECU is going to be nearly at its maximum with these cams.
When Andrew first did his (which due to base circle restrictions are MARGINALLY less agressive - and definantly less agressive in the overlap department), he went through a whole bunch of things, increasing fuel pressure, trying to get the injectors opperating at higher duty and so forth just to get the AFR's back within an acceptable range. He was, at the time running CAI, full exhaust (engine back), extensive head work, cams, beefy leads, beefy plugs, light weight flywheel and so on...
Thats not to say these things wont work on a standard engine, however it will start getting to the point where the stock ecu just refuses to add more fuel (gone outside of its ability to learn/care about the AFRs)
to get the most out of them you should consider at least some sort of fuel computer, and adjustable cam gears as a minimum. not to say you wont get SOMETHING out of them without this stuff, but it will most certainly help you out and MAY Solve the problem (not sure how your ECU registers a missfire, but could you be lean enough when on power to start running into deto issues? something to definantly check out).
At the risk of sounding like a broken record, i STRONGLY suggest you look into getting a microtech. There are a few AVs who sell pretty well wire up and drive off kits, and theres a few little tuning and wiring tricks i've picked up along the way that may translate to my car's american kin. The stock fuel system is more than capable of providing enough fuel to get your AFRs back where they should be, its just a case of the standard ecu not having enough give in it to provide the fuel system the right instructions.
