A Cobalt SS Owner is Offering to Tune My SS/TC w/ HPT for $50. Too Good To Be True?
He says he's got the tune setup for 91 octane fuel and other options, too, but I want to go the 91 route since this car is my DD.
He used to post here up until 2013 or so. I've seen one thread where someone said the guy's HPTune was a great deal and worked well. I want to get it done because... I mean, ****... That's one helluva price! But I want to know what you guys think.
He mentioned that since his car is also a 2009, he's got that tune saved and ready to go without issue.

Sounds like he had his tuned saved and is just flashing it over to you. I would stay away from that. Fine a good tuner who will tune your car with an custom tune for your car not someone elses tune

You have to buy credit from HPT to unlock it to a vehicle. Those credits cost $100. So he'd have to pay $50 out of his own pocket....No.
I think he means $100 for credits and $50 to flash the tune. I had the same deal, you just need to look up a track record of this guy, you don't want some whole in the wall messing with thousands of tables on the bosche ECU....Your going to have a bad day.
My tuner doesn't even have a Chevy anymore still hangs on to HPT but doesn't tune publicly. I watched him since 2010 when he bought a SS/TC throw stupid power at it when he tought himself to tune, blew it up. Started over and now with the limits found knows not what to do. Figure blowing up your own car is a great way to test the limits LOL but he knows what NOT to do now (he blew trans not engine, didn't ramp and had 26+ or so psi on meth made over 420ft lbs and blew 3rd)
^This is why I go back to him.

Stay far away from this.
He probably has your model year unlocked on his cable so there wouldn't be a $100 fee for unlocking your specific VIN.
But for $50, you're either getting someone else's tune, as has been said, or you're getting a **** tune altogether.
The reputable tuners on here can command 250-350 for a custom tune. Anyone offering theirs for 50 bucks tells me they are not very good.

If he is jus using a ZZP canned tune or a gm stage1 esque tune I could see someone selling them cheap just to make easy money. But I feel like your probably just getting some half assed tune he put together himself which could be either dangerous if it's aggressive or setup for a specific parts/altitude. Or disappointing and a waste of money. Or both.
Without more details I wouldn't do it..

Going through his post history, it seems like he's had a lot of issues with his car. Maybe it's best I stay away anyway.
Someone in another thread offered to tune me in mid-June and he's an active member here, so I'll wait on that.

The other person that offered has a reputation here on the site anyways; i think that's better just for the fact that you can research/ask others about the work they've done. good luck man.

Wow really, I feel like I need to defend myself on here. So the guy is talking about is me.
First of all no im not just going to copy my tune and flash it over to him. The timing tables to start with yes, I will copy from my tune but then I need to retard the timing based on the knock retard, until there is no knock retard at all. I will also need to calibrate the MAF which I bet only a few people on this site even know how to do properly to ensure that the cars short term fuel trims and long term fuel trims do not fluctuate.
I thought I was doing this person a favor by tuning his car for $50 because I already have all 09's unlocked on my unit. But now I know don't do anyone any favors because everyone else will talk crap and think I have no idea what im doing if I give a good price. I do it just for fun now, not really trying to make money, just educate and help people.
I have done e47 tunes for lnf, I have done race gas tunes also. I do know what im doing, and anyone that knows anything about tuning the lnf would know that from what I just said.
The reason I no longer post on here is that I sold my car back in June and now have a 335i.

^ Chill dude. It's great you're advocating for yourself but don't be mad at the OP. He too was advocating for himself and asking for more information about you. Nothing was personal here.

Ask me any questions about tuning the Lnf and I bet I know the answer to it.
Like for tuning for E47 you need to multiply the injector const. by 15% this is because E85 requires 30% more fuel, so if it was full E85 it would be x 30%, but you can't do that with the LNF because you run out of fuel in the top end with high timing advance. I remember that zzp used to make a 5th injector kit that would compensate for this, with a manual fuel flow adjustment, that would go into the evap port on the intake manifold.
Go ahead ask me a question try to stump me. Each and everyone who posted on this thread know absolutely nothing about tuning a lnf, so how can you talk crap about me.

I'm not mad at him at all. I'm upset with all the people who replied that know nothing about tuning at all and just want to throw in their opinion based on no facts at all.

This is how nice people like me get treated for trying to do something nice for someone. It makes me sad because this is why more people do not offer their help, because they fear others will criticize them.

I didn't say anything negative or offensive, did I? I'm sorry if anything I posted came off that way. My car has 121k miles, so I have to be careful with whatever I do with it from this point on. I just wanted to be sure I wasn't risking my engine blowing up or something.
I hope I didn't offend you, Bryce. You seem like a good dude. Maybe I was swayed by people's warnings too quickly. I should've asked you what you think about all this, but I guess it's too late now.

Yes,the injector window has a limited amount of time so that is why you need to increase the injector const. But You also want to increase the timing in the top end to make more power, this is the entire reason you would run e47/e85. I was not saying the timing is an issue, but the more advance your timing is in the high rpms would mean you would need more fuel to prevent knock. More fuel actually keeps the cylinder temperature down and is safer on your engine, running your car to lean is when you can blow it up.

You don't need more fuel to prevent knock on e85 or e47 with the LNF, people run 0.88-0.90 PE on e47 up to 24* with no knock, and e blends burn cool enough to not need extra fueling to cool the cylinders

But if you are a reputable tuner (not saying you are or aren't, I have no idea) don't blame the people on here for being skeptical. Blame the people that have given them the reason to be skeptical for offering similar to what you are offering.
