Drives different after cam install - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Smoky10 · 06-16-2011, 10:50 PM

I got my cam installed today. My car was also dyno tuned and setup for this cam. My question and reason for starting this thread is should the car drive slightly funny? Example I started the car and drove to a red light about 100 yards away and it died. Then I drove it home from the shop it was tuned at, and as going through the gears sometimes there was a little hesitation. I called the tuner after it died the first time and he said that the computer was just relearning itself. But she doesn't feel just right, shifting into the gears sometimes is very nice and smooth other times the motor kind of bucks. Just wanted to hear some opinions.

Thanks in advance,

Brandon

Bad tune.

camaro1 · 06-16-2011, 11:03 PM

tune is wrong,, should not be any stalling or hesitation and the computer does not need any learn time after it has been tuned,, all the learning would have been done before you got the car back

fourmz · 06-16-2011, 11:06 PM

Get it re-tuned

mikeSS · 06-16-2011, 11:13 PM

any ways not to high jack the thread. but could somebody answer a quick question for me. after my cam install i notice my car would rev past stock limit. does the new cam shaft give me a little higher red line now ? again don't mean to jack thread.

rev limiter is in the tune,, your tuner raised the rev limit,, you can raise the rev limiter with a stock engine and run it to 7000+ rpm but its not going to make any power at that rpm or last long

"RED LINE" has more to do with the total engine build more than just the camshaft,, a built engine that is balanced, better oil system, lighter valve train can rev higher and safer than a stock engine with just a cam

*mlee* · 06-16-2011, 11:26 PM

What are the specs on your cam?

Was this done by Jason? Hope you get it resolved soon man.

Smoky10 · 06-17-2011, 02:20 AM

No I did talk to Jason tonight though and I may take it to him, but I had it done by a shop in P'cola.

hollandtwin27SS · 06-17-2011, 03:33 AM

Bad tune it should start right up and not die at all

Scott@Bjorn3D · 06-17-2011, 04:12 AM

Well if your tuner said it was fine and you can get it to Jason that would probably be a better deal for you.

A word of caution, if it is really acting up you may want to have it flat bedded to Jason to make sure you are not damaging you motor.

Ahh okay xxx. I haven't had any issues with Jason tuning mine, so I hope he can fix you up. I'll see you at the grill and growl.

wow, thats a long way to tsp...there's got to be a good tuner closer...

Slowhawk · 06-17-2011, 08:02 AM

First of all we need to know what Cam is in it. Some cams will not run smooth in low rpm area's. If the bigger cams ran like stock then nobody would install the smaller cams.

I do agree that it should not stall and the throttle should have a smooth operation.

Call Phil on here that tunes out of Tampa. He is probly the best LSX tuner in Florida.

Tampa Tuning · 06-17-2011, 08:20 AM

Each time I adjust the MAF in the drivability portion of my tune, I reset the fuel trims. Sometimes guys forget to do that.

With a cammed car, if they tuned the car when it was warmed up, it can have cold driving issues till it warms up.

If it still has the stalling issue , he may have to adjust the throttle cracker and idle timing slightly to help prevent it from stalling.

It does sound like it still needs a little fine tuning to make it drive better. The bigger the cam, the harder it is to tune on the low end of the RPM range

Unreal · 06-17-2011, 08:43 AM

Like they said above, depending on the size of the cam the surging/bucking could be as good as it gets, or need more work. Large cams don't like low RPMS so you may have some surge below 2000rpm. Car should not be stalling though.

xxlbeerz · 06-17-2011, 09:05 AM

Mine would almost die and backfire a couple times on the first day, never completed died though. Still does it occasionally. I still don't know if it was the tune/cam, or me not being used to the difference. Scared the shit out of me though when pulling out into traffic and having the car almost die then spring back to life!

I do have to keep my RPM's a bit higher now for smooth take off. I think I need a retune as well though, so I may be a bad indicator.

sounds like your tune needs some work also.

I have the same problem .. I don't know my cam space, the guy who build my car would not give it to me.

KMSRS2SS · 06-17-2011, 10:32 AM

It should never stall...ever. Do you feel the hesitation during acceleration? The hesitation could be the computer adjusting to the new found power. You rarely notice the nannies kicking in on a stock car but it is very noticable in a cammed car. I wouldn't get on it too crazy until the car is tuned properly, but you could turn the nannies off if you are still driving it to see if the hesitation goes away.

Smoky10 · 06-17-2011, 01:12 PM

To those asking what cam it is. It's a 231/236 TSP cam.

Every time he ran the car and adjusted his tune he let the car cool off for about 30 or 40 minutes. I will also take it back to him and ask him to make some adjustments. Also someone has suggested that I should come see you. Would you mind hitting me up with a PM with your price to adjust me car?

I actually did turn all the nannies off, and left them on. I also made sure to keep the RPMs up. But was told that the car shouldn't buck or serve above 1600RPMs, but it still acts funny. Also taking off from a dead stop is the only time that I don't feel any problems.
