Ok Talked To The Guy Over At Pcm Forless And He Said I Probley Have A Hotcam(WAS IN IT WHEN I GOT IT) I Know I Have AFTERMARKET Rockers And I Know I Am Running The Stk Chip ---the Car Runs Fine Now A Little Goofee At Idle But Runs Great Otherwise--would It Be Worth It To Get The Reprogramed Pcm Its 175.00 + Core WHAT ARE THE BENIFITS

 

Without knowing the exact mods, I would have to say you're better off with a local shop and dyno time than PCM4Less this time.

If you were able to log some data for them and were very good at taking notes then I bet they could do a bang up job for you.

 

The Guy I Talked To Made It Sound Simple He Said I Probley Had A Hotcam Or It Wouldent Idel And I Know Most Of The Other Stuff That Had Been Done Also Wouldent A Almost Perfect Tune Be Better Than None With The Mods I Have

 

Certainly a better tune is by definition, better.

But will you be happy with that?

$175 bucks for a better tune isn't a lot of money and it isn't wasted money either...unless you later choose to get a more exact tune.

Have you priced out a custom tune at a local shop?

If the locals charged say $250 would you go with them instead?

There is a rule that a friend of mine has regarding electronics especially laptops and speakers. He will not look at laptop prices after he buys one nor will he listen to other speakers after he's made his choice. I think there is some wisdom there. If you go with the PCM4Less tune, promise yourself that you won't worry about tunes for a while and you'll enjoy it.

 

ON A STOCK ENGINE THEY WILL BASICALLY ADVANCE THE TIMING AND BRING THE FANS ON SOONER.
wILL ALSO TAKE AWAY OF SOME OF THE LOW rpm drivabilty But engine will rev up there noticeably better. Happy with the mild tune on the 94.

 

With PCMforless, you can get the any tune setup, which allows you to data log and send results for new chip...lifetime...

 

Damn It Is Hard To Read When Every Word Starts With A Capital Letter.

 

 

Agree to Disagree: Thats why you would data log your engine, Idle, part speed, full speed, and send to them (pcm) to do the custom chip, cheaper and easier that going the full dyno...

 

Of course every engine will be a bit different, so it would benefit you to have a dynotune by a well known tuner. from what i hear this is around 400++ to do this and your will need a retune when you do other upgrades.
With a mail order tune you will have the benefit of very discounted reburns for the psm evertime you change something . If you get into it get the proper cable to connect the pcm to the computer and they can email you update tunes that you will download right to the pcm.
Actually pretty simple. look at the guys on this forum that do it.

 

If you dont know whats in it how can someone do a semi accurate mail tune, they cant.

You need to bring it in to someone, have the hook up a laptop to it and do it from scratch, otherwise you are throwing money down the toilet.

 

thank guys
i think i will just leave it alone it rung great idles fine so if it ant broke dont fix it

 

your no fun.

 

nO fUn At aLl

 

well i just give up, sure i would love a perfect tune but i cant find anybody in michigan, i searched the web made call and no one here that i can find, so im stuck

 

I do agree with Vinnies87 that, with the data, PCM4Less could get it right.

There are lots of 'vettes in Michigan. I would humbly suggest that you post a request here, in CF-OT, in C4 Scan/Tune, and E&R Great Lakes for someone who already has the ability to log data from your car to help. Check with PCM4Less to see just what they would want. It shouldn't take more than a few minutes for someone to collect the data for you.

I think there is one (at least) of the software based scanners that will let you make 20 scans with their trial version. You would then only need your own laptop and a cable that you can buy or make from plans found online.

This isn't a pressing issue for you so you can bide your time and get it right and on the cheap too.

 

Robert,

If you have the hotcam, you can get a very good mail order tune from pcmforless.
I may be one of the few people on here who can speak directly to their mail order tune vs a dyno tune, both from pcmforless and using the hotcam.
With their mail order tune I made 356-357 hp. About a month latter, I had Alvin dynotune the car and he got 362 hp. So I only gained approximately 6 hp.
There are alot of myths out there about mail order tunes IMO and I will share a few I have heard and my opinions
Myth 1 A dyno tune is much better then a mail order tune. IMO this is not always true. First off, if it is a common modification such as a hotcam setup on a LT1, the bigger and better companys such as pcmforless have done so many on the dyno, that they are, in fact, selling you a dynotune already designed to your setup, it was just done on someone elses car. Quite like the factory tune in any car. We all know that each car from the factory is not dyno tuned. Rather one tune is designed and then programmed into many identical cars.
Any tune, being dyno or mail order is only as good as the programmer writing it. So it is very possible that you could hire a dyno tuner, who does not fully understand your car, or your cars programming, and he could do a poorer tune then a very knowledgeable programmer performing a mail order tune.
Myth 2 A dyno tune will help with driveability issues. IMO this is not true in most cases, unless you find someone such as TJWong who uses a mustang dyno. If your tuner is using a dynojet, they are only good for WOT tuning. Idle, part throttle, etc, is not going to be any better then your mail order tune. The dynojet operator is going to be limited to data scans etc. which your mail order programmer can do as well.

But back to your car. Yours being a 94 is probably going to handle the cam change better then my 93 due to the differences between SD and MAF systems.
That being said, mine does not run to badly at WOT on the stock tune, but Idle and part throttle were way rich and rough. Alvins tune made a big difference in the way the car idles and part throttle as well.
If you do the mail order tune, pcmforless is hard to beat, but beware, there are other so called tuners out there who do not know what they are doing and can just rip you off!! Trust me, Im speaking from experience on that!
Good luck with your decision!!

 

I did PCM for Less.

They changed the shifting point on my A4 and a hell of a difference.
My LT1 goes over 6,000 RPM
Re-calibrated my speedo (new 18" wheels)
The Vette runs better

I sent my ECM and it was back within a week.
