I am pretty sure you need to get a tune for a new cam. If you bought the car and the cam was not stock and the previous owner didn't know the type what would you do?

 

well, i would probably be curious enough to know what it is, to the point that i would probably pull the cam out and look for numbers on it.

 

take and get dyno tuned, and just go from there. no real way to tell what the cam is without taking it out.

 

A wide band is all that is needed. Reason most tuners want cam numbers is because depending on the numbers, they have a base line tune they can use on the PCM and make improvements from there.

 

just get it dyno tuned, wont be too much more then a pcm mail order

 

the hell it wont.

It cost me 125 for my first mail order. for a dyno tune (here at least) is around 500

 

Pcmforless has the email tune for $75. The dyno shop here is very expensive also. They figured 500+ to get it dialed in just right. Problem is, I am always changing the car so the dyno tune would not be correct after more mods.

 

So that shop won't give you a discount once you've changed up your tune?

 

Where do you get a dyno tune at lol? Better yet who did your mail order.

Yup.

 

What I will do is get the dyno numbers to Pcmforless and have them adjust if needed. They will do that for free for 6 months. They charge $75 for 3 pulls.

 

could you stick a degree wheel on the crank, and pull the valve cover to put a dial indicator on the valve spring/tip.

try to get an idea of what the lift would be and some of the opening /closing points and get cam numbers from there.

I'd be curious as to what it had and would probly pull it out anyway but can be alot of work just to do that.

Does the car start? how does the cam sound? comparable to any of the popular grinds like hotcam, cc503, cc306? if its a mild/medium cam get a mail tune for a hotcam/cc503 and it should be pretty close. Then dyno from there

 

I will look for some sound clips and see if any are close. It has no problems and I guess if they can get the A/F right from a dyno run than that is good enough for me.

 

yeah knowing the cam may give you an idea of what to expect if you've tuned motors before but starting from scratch with a WB and getting air fuel ratios, it doesnt matter what you have. Just tune it

 

what is pcm4less number bec i have their old number and it dont work
thanks steven
