Why would you buy a tuned pcm when you already own a tuner?

Getting a tuned pcm is just wasting money. It's not going to help you learn anything. You need to drive the car, log what it's doing, get the fueling smoothed out (MAF table), and then address timing. It's not easy and it doesn't offer instant results. You can expect to log and make changes as little as ten times. If you're looking for simple, sell the tuner and go to a shop that can dynotune your car.

Yea he does. You guys are right. I have got to learn to tune myself or else what IS the point of owning my own tuner. I just went outside and scanned my car using the dhp tuner software (which is something i have never done before in the past) because i was using my aeroforce gauges. Now that i got the hang of how to scan using the software, i will start tomorrow. Thanks guys for pushing me in the right direction Very Happy

getting a pretuned pcm DOES give you a place to start from (IE Intense L67 tune for a top swap/3400 swap)

Yeah, but he has neither of those. He did a engine and trans swap if I'm not mistaken. So everything he needs is available to him on the internet. Not sure why you'd need a starting point tune with your example either. If it's more convenient for you to spend money on a pcm tune then so be it. It's certainly not necessary though.

IMO spending $100 on a shelf tune is better than trying to guess or do a full write and have it possibly fry your pcm... I was looking it as $100 for an EXTRA pcm w/a shelf tune so you can see where they edited things and learn from there...

What's the difference in frying one pcm over another? You can get stock pcms for $30 all day long from the classified sections on the various forums. Use the $70 you saved for gas for logging. Whenever you write to the pcm, you run the risk of bricking it. Are you saying he should just get a OTS tune and never tune his car because it might brick the pcm.

Vendors don't change enough things in the pcm to make it worth the money. I noticed maybe 10 tables that got changed in the ZZP pcm that Helldo had in the SS when I bought it. The majority of them were transmission tables. The MAF tables remain untouched. They lower PE, change fan settings, dumb down the knock sensors, and raise shift points. Well worth the $100. *sarcasm* Maybe that's just ZZP. I know Intense has a few different options that you can change. It's still not something that you couldn't achieve and a weekend with the tuner and a laptop.

If you own a tuner, I don't see the point in getting an OTS tune. Use your tuner to dial your car in to a safe point and take the money you saved by not buying the OTS tune and put it towards a dyno tune.
