383ss Posted September 19, 2004 Report Share Posted September 19, 2004 finally got my 221/221 cam installed today. I was really suprised at how poorly it idled with no tuning. it really wouldn't idle at all, but was fixed easily with a couple tweaks. now I can't even tell it has a cam by the exhaust, not sure what I think about that putted around tonight, but I'm going to get on it tomorrow, get dyno'd monday and hit the track wednesday if everthing goes as planned I'll keep you guys updated. I don't think anyone on here has a C1 cam, do they?? Link to comment Share on other sites More sharing options...

383ss Posted September 22, 2004 Author Report Share Posted September 22, 2004 well, I had to go out of town this week, but I do have a gas mileage update. got 15mpg with 95% highway driving at 75ish mph I was pretty happy with that. maybe lost .5mph with the cam change hwy driving anyway Link to comment Share on other sites More sharing options...
marc_w Posted September 23, 2004 Report Share Posted September 23, 2004 Sweet. Definitely keep us updated. What LSA is it on? My TR220-112 idled great in P/N... but liked to give me problems in gear. I had my idle raised to 650 or so to minimize problems, but the lope was still pretty apparent. I wasn't able to get the cam to respond well to tuning changes. What did you change?

383ss Posted September 28, 2004 Author Report Share Posted September 28, 2004 LSA is 112. the only thing I have changed so far is the idle and I raised 'Idle Airflow vs. ECT' and 'IAC Park Position Airflow vs. IAT' and added 2* timig from .08 to .24 in the 400-800 range. solved 90% of the idling issues but still have slight surging. haven't had time to mess with it lately... haven't done any WOT tuning yet, but had it at the track and didn't get in any good passes because of E-fan problems Link to comment Share on other sites More sharing options...
marc_w Posted September 28, 2004 Report Share Posted September 28, 2004 Cool. I heard something weird on the HPT site - I think it was Keith over there saying the idle airflow values are airflow values that the IAC motor is expected to pass through at the stock settings. Here, I'll just post it, before I lose anything in the translation... This really threw me for a loop........ I raised my idle airflow values, and got what seemed to be a better idle. I have since gone back to stock there to "KIS". Link to comment Share on other sites More sharing options...

I had thought I'd read about every thread on that site now I have an O2 sensor that went out truck is misfiring like hell! Link to comment Share on other sites More sharing options...
