I went to a dyno that had hp tuners to try to tune my automatic cobalt ss. At first I guess he couldn't get his laptop to comminicate with my ecm(i guess). Then he ran an update and it hooked up but I guess the software said something about not having a license for my ecm. I was there I waited for three hours while he tried to figure out why it wasn't hooking up to my computer. We looked on forums and he said something about their being some computers that are not supported by the software, and that was the only explanation that he could think of.
I thought hp tuners supported the automatic 2.4's, is this the case or are their some that are not
if they are supported what might have kept him from connecting to my ecm
if it turns out that this guy just didn't know what he was doing does anyone know anyone who tunes the 2.4's in the orlando area

 

it does. the "license" is bought through HPTuners. the credit system...its not free for tuners to tune a vehicle because they have the software..it costs them money.


if he did have the license for the car (which is possible to do a unlimited model/year for more credits which lets you tune the same car type)...when he ran the update, it might of fucked it up.

 

he didn't have the license for the car but he was saying that a prompt was supposed to come up where he could purchase the license and for some reason that prompt was coming up. I remember him saying something about it saying I guess faulty pair or bad pair with the vin and the ecm I think, but i'm not sure

 

im having the same problem

 

Dave what shop in Orlando are you going to to tune your 2.4?

 

That's what sucks the most about it, it wasn't in Orlando I went all the way to sarasota to tune it. 2 hours driving each way. In other words I wasted a total of eight hours my day today just to get a free pull on the dyno and the promise of a lower price if he figures out was wrong and ends up able to tune my car. He sent an email to hp tuners so I'm just waiting for a reply

 

Man that sucks hope you are able to figure it out.
Where there no shops here in Orlando that could tune the 2.4 with HP tuners?

 

So what did you pull on the dyno?

 

if this guy doesnt know that you need credits for HPtuners, he should deff not tune your car dude.

 

well I was having a hard time finding a shop in orlando that uses hp tuners so when I found one in sarasota I jumped at it. It doesn't help that when you call a dyno noone ever picks up the phone and noone ever calls back when a message is left

I'm sorry for not getting it but why do you say that

 

fixed it, sorry it didnt make sense. Credits is something very basic that everyones knows even the biggest newbies in HPtuners like myself. lol. Well im an intermediate now.

 

what this guy is saying in lamens terms is do you want someone who doesnt know how to change your oil swapping out your pistons and doing head work on your car ?????? its the same thing if he doesnt know the most simple thing about hp tuners you think hes gonna be able to tune your 2.4 cobalt auto with mods haha yea right

 

he understood that he needed credits he said that for some reason the prompt was NOT coming up for him to purchase additional credits.
does that make sense.

134 hp 137 ft/lbs

 

kind of but not really , thats not that bad i know this guy who turboed a civic dx i dont know what year looked like maybe 99 00 said he was running 161 hp and 160 lb of torque at the wheels so you all are not far behind a turboed civic

 

the guy has used hp tuners before but he has used it for gto's. He's never done a cobalt before. But when I spoke to him on the phone he made it seem like it shouldn't be a problem. That's why I drove all the way over there. Those anyone know anyone who is tuning 2.4s in or near the orlando area?

 

If you get the credit system figured out and you are able to tune, there is a known issue with the 2.4 ECM. You may not be able to write to partial files. You will gets write fail errors. If that happens, you can do a write total, and that will work. HPT is aware of the issue.

 

woah wait. doesnt the 2.4 ss come stock with 171 hp?

 

171 at the crank or flywheel
134 is how much hp my car is pushing to the wheels. Two different numbers. Horsepower at the wheels is always less than at the flywheel because power is lost in the drivetrain. More power is lost to the wheels in an automatic than in a stick. I've heard that you should estimate about a 18% loss in a stick and closer to a 25% loss in an automatic.

 

wait wait...he said that a prompt kept coming up for him to purchase additional credits??? if thats the case then it sounds to me like he needs to purchase additional credits. that doesn't seem like it would take 3 hours to figure out to me but maybe theres another issue going on.

is there a difference between purchasing a license and credits?

 

Each year/model of a car has to be unlocked. It costs 6 credits to unlock an entire model year. So for 6 credits (about $300), I can unlock every 2006 Cobalt SS S/C. Therefore, I can't tune any 2.2, 2.4, or any other year unless I unlock them.
Or you can buy 2 credits to unlock one Vin number. Therefore, I can unlock my car, but not tune on anyone elses until I unlock theirs

 

No that's my bad, there was a mistake in the first post that you quoted. I fixed it.
He said that a prompt is supposed to come up for him to purchase the credits but for some reason it wasn't showing up. That is why he emailed hp tuners to see if they can give him some support, because he couldn't figure out why the prompt wasn't coming up.

 

Wow... I'm running 150 hp and 148 ft lbs to the wheels. Even though I'm a 5 spd. you should still be making more than 134 with even minor mods.....

As for the ecu, be careful that he does an entire re-write. I tried doing the recaliberate with my HPT and my ecu wont let me. I have to do a full re-write. I ended up almost shitting myself in the middle of nowhere at 2 AM because I was tuning. My car wouldn't start or anything once I had tried to re-write it... it erased the computer and tried to recaliberate it, but my car wouldn't let it until I chose the full one. Then it worked like a charm.

 

I found that one out the hard way LOL Right Panblackrose

ummm you had to re-write it ? LOL

 

hey i got a guy at my dealership that does reprogram that apparently is not traceable (wont void waranty) is this the same thing or does anyone know what he does

 

Dave send me a PM if you still have not found some one who can tune with HP. I found a guy.
