420A Brian crower cams p0300

The issue isn’t whether I could tune it or not. The issue is not knowing what the issue necessarily was. If something was bad then it wouldn’t make sense to try to tune it. But now I’m just trying to see if I can get a simple fix by getting into my ecu and making my engine code inactive or if I absolutely have to by an aftermarket ecu. So I’m gonna get some adjustable cam gears and try to get a simple tune done if possible before putting all that money into an ecu when I’m not building my car for any crazy gains or anything

I agree. But when everything worked prior and the only thing you changed was the cams logic would say the cams are your issue. Is this your daily? I just got the brian crower stage 2s as well along with their cam gears. Looking forward to them

Ya it was my daily before all the issues. After I get it sorted out I’ll start using it as my main car again. I didn’t know BC made cam gears for the 420a

No I have a 4g63. I just upgraded the turbo, added bigger injectors, 3in exhaust, and I'm getting the cams and cam gears installed hopefully next week. They make cam gears for the 4g63, idk about the 420a motor. I wasnt gona even get cam gears but I bought the zaklee clear cam cover so I wanted something nice to show, I wanted hks ones but there to expensive. Brian Crower is half the price and their a quality brand.

Man... Did you upgrade your valve springs?

I've ran Crower 2's on stock springs forever, but had random misfires at idles and seomtimes WOT, no damage or anything, did it like that for about a year, only way I solved the misfires were for upgrading a spring and retainers set.

You might need heavier duty valve springs to go with those cams, and maybe new lifters too. Hopefully I found your issue this time
