running without a tune?

[truekoa]

Well I finally have enough for the cam setup I want, the only thing is I won't have any money left for a tune.

Is it possible to run without a tune for awhile, I know I will not get the full benefits of the cam but will it hurt me in the long run?

This is what I'm using for my cam setup:

Abbot NA cam
105 springs
Lifters
Hardened pushrods
install kit from ZZP (gaskets, bolts, timing chain dampener)
P&P intakes
stock heads

Gracias amigos.

anyone?

I'm thinking of just parking the car for a few weeks and sending the PCM off to PCM4less or something.

I don't believe it will hurt anything with daily driving. Your stock o2 sensors can handle any closed loop fueling but tuning is very very important during open loop. When you go WOT your car goes into open loop and can't use the stock o2's for fueling. It could run really lean and too lean means KR and other bad stuff caused by the high heat temperatures of the lean fueling mixture.

dont send it to pcmforless for a cam tune...its hit or miss for it to be any good.

FWIW, when I installed my abbott NA cam, my car refused to idle without a tune. It started up and ran the first time...but everytime you came to a stop it died...you had to keep you foot on the gas and the car in neutral to get it to stay on...then try and neutral drop it as softly as possible to get it to go. (I had to do this to get it home, my car couldnt stay at my buddies place another night, and the laptop I brought was unable to write a tune to the car, I had to use my other one)

Re: running without a tune?

With the abbott cam I wouldn't run it without a tune becuase it uses different pushrods and the cam profile needs more fuel than other Comp cams.

Re: running without a tune?

I used stock pushrod length? 7.05 I believe it was? thats what abbott reccommended?

Yeah im staying stock length, just going for the hardened ones.

I guess I'ma just have to wait some more and save up for HPTs

Re: running without a tune?

Yeah I'm kinda in the same boat here, but I'm going with a gt2 cam. I'm not gonna be able to tune the car after I install the cam, at least not for a while. Plus id rather have someone that knows what they're doing tune it for me and there's not a dyno anywhere near me that I know of.

I would say save for hpt and do it yourself rather then go to a dyno to...if you decide to do more work later your looking to spend more money to have them retune it...and a dyno tune costs as much as hpt...PLUS, you can recover money from hpt if you sell it later...it holds its value ...you cant recover much from a tune that is specifically for your car...

Hmm I recall Radracer( member on here) has a GT2 on his car and ran it for a year without a tune and was fine.

Yeah I might just save for HPT. I'm still figuring out the credit system though. So any change i make uses one credit? Also I heard about some ppl that have the PRO edition and can do unlimited changes to their car?

Can someone clarify? I've emailed HPT but no response yet. Gonna start reading the stickies on here and FTV6 later today.

Re: running without a tune?

Personally i would not drive the car much without a tune. After i washed out my rings we came to discover that it wes due to driving the car for so long without a tune. It was running to rich and not dialed in proporly. Thats what myself, my machinest, and my tuning guy all agreed on.

They give you like 8 or so credits to start with, you can use something like 2 credits for your specific VIN number and you can edit it and scan it as many times as you want. If you want to tune any same type vehicle of the same year you have to spend like 6 credits. So say, if your friend has a 98 camaro, and you have a 98 camaro, if you spend the 6 credits you can tune yours and his or anyone else that has a 98 camaro. That's mainly used for dyno shops I imagine.

The people who ordered HPtuners when they first came out only got 1 vehicle but it tuned all years for that vehicle , so i ordred Camaro 3.8 , so I can tune all of them. Then last year they made eveyone go to the PRO-edition like $199 and you could add 3 more cars for 99.00 each so I added my DAD's 05' 3.8 Buick which does all years and just for the hell of it , and I ordered /4.85.3/6.0 00' GMC/chevy trucks need to pick a engine, and then 02' LS1 Camaro again all years so I'm not locked into any vin#, they made up for only giving only one vehicle when they first came out, so I want a 00' truck then I will have hptuners already and if I want to do a LS1 swap or a 6.0 I already have Hptuners. Was a good deal for me since if I didn't do it before Sept. it would of been $399 a car for all years and like $499 for PRO Version. But I always thought people needed shorter pushrods for thr abbott cam since the cam profile was higher, my bad.

Im am also about to get underway on my cam install, im going to run a similar set up but im going with the GT2 cam, True what cam install kit are you using? Kit 1,2,3 or 4?
And also do the cam bearingS need to be replaced? I'm assuming they do.

Sorry not trying to thread jack just figured I'd ask since everyones on the subject.

I'm going with kit 4. All the gaskets are included, the rocker bolts, cam, bolts crank bolts, and a timing chain dampener. (going to replace my timing chain im at 127k miles)

When I was reading up on the cam stuff I really didnt see much about cam bearings I was planning on reusing mine.
