V1 Tuning LNF

[SmsDetroit]

Are there any other tuners out there other than HP tuners that people use? Are there tuners that don’t require paying for credits or unlocking the ECU?

Several options listed here but don't know how many are still available.

Not sure what you mean by unlocking the ECU, it isn't locked unless it's been tuned before and it was locked then.

I thought you couldn’t write files on a ecu unless it’s been unlocked. Shows you how much I know. Lol.

You aren't totally wrong on unlocking ECM's, that is required on a lot of newer vehicles. But it doesn't apply to the Cobalts. Also understand that that HP Tuners isn't a "canned" tune like is available (or was available, I think the EPA has cracked down on a lot of these) for some vehicles. You will have to make changes yourself or buy a tune from someone remotely.

What are you trying to accomplish with tuning? Are you sticking with a basically stock set up or going for upgraded turbos/cams/injectors? If stock we can walk you through the basics for tuning the MAF and other basic settings, although I'm still learning on mine. Right now, it's running well enough that I hate to mess with it, but I'm probably leaving power on the table. One of the many things to do this summer is to work on the tune some more.

HP Tuners can also be useful for trouble shooting issues, although if not going to the step of tuning with it a TECH2 clone is cheaper and probably better for trouble shooting.

Looking at at staying stock turbo and internals for awhile. I have 3 bar maps to install and if I correct with those and a tune you can get 30-50WHP which would be good for this summer

We can walk you through the changes for that.

I guess I need to get at tuner than.

I just picked up a K04/3 bar maps tune from ZZP cost me $200 + $100 in credits in HP tuners to flash. not terrible to just set it and forget it
