Is it possible (and probable) to run cams (such as HKS or Buddy Club 272/272) without a flash and not have any problems? I plan on installing these and then making a trip to WORKS (a 4 hour drive) to get everything tuned. Am I going to run into problems, or will everything work out fine?

 

You will be fine.

 

You dont need a flash to run cams but the idle wont be as good as it will be with the flash cause tuners adjust the stock idle speed motor etc to help smotth the idle out alot.

 

You might have some stalling issues in stop&go driving, but freeway cruising should be ok. I remember a guy a long time ago who drove around on 272's and no tune for a while.

 

just stay in closed loop ecu operation. aka no boost. If they stumble too much at idle, (my 272 gsc's were fine) you can bump your idle up with the screw on the intake manifold

 

^^...

or if ur too lazy, just keep ur throttle slightly open at all times by keeping ur foot on the gas. Ghetto fix since its only a 4hr(mostly highway) trip

 

No Problems or what so ever ...
my Evo is Totally Untuned with intake, 272 Cams & still running smooth .. but doesnt mean im gonna leave it that way ! ...
Saving up for a tune at the moment ..
the cams on my evo .. just changed the exhaust Note .. a lil lope ... that's it

 

it's been one month with hks 272's and no tune and i'm completely fine although I was told not to go full boost and redline. No stalling what so ever.

 

well, with cams you have more air entering into the motor, how much this changes your a/f ratio, i am not sure. If you have a stock ecu tune, you run rich as **** anyways, so you should be fine being untuned. But still get them cams tuned!

 

alright sounds fine... i'll just keep off the upper RPM ranges and all that jazz.

w00t!

 

FYI - My tune for cams means a slight timing retard up top and 12% LESS fuel up top as well.

The timing pull is due to the lean AFR that the tune provides so in reality you can beat the living crap out of your car without a tune and it will probably be safer then it will be after a tune (just with a little less HP).

 

completely safe

my buddy in a 2g eclipse just put 264/272 cams w/ adjustable cam gears in his car and its running like a champ

 

i have been running buddyclub 272/272 with all supporting mods in my car for about 4 months now, i have never had a problem, i finally got around to sending out my ecu yesterday to Al at dynoflash to get a reflash
