jtrosky Yeah, when (if) you buy the Overkill tune, he will supply both an 87 octane version and a 93 octane version (basically, just different ignition timing maps) of the tune. I no longer use my Overkill tune (I was looking more for "comfort" over performance), but I did use it as a learning tool - and using it for that alone is worth the $150. By comparing the Overkill tune to the stock tune (via the HPTuners "Compare" function), you can see exactly what Overkill changes and really learn from it. And then little by little, along with some reading over on the HPTuners forums, you'll start feeling more and more comfortable making your own changes to customize the tune to your exact "specifications". In particular, the shift points, amount of torque management and gas pedal sensitivity are some of the easier things to really tune to you exact preferences. Some of the stuff is *very* technical and involved (such as idle tuning!), but other things are actually kind of easy to tweak - and small tweaks to things like the shift points can really make the car behave just like you want it.

If you like to "tinker" with things, you'll love HPTuners. Just go slow - make minor changes and monitor how it changes things (the HPTuner scanner is an *awesome* tool to see *exactly* what your car is doing!). You can log a drive and then review it later, frame-by-frame if you want - and then make more changes based on what you see in the logs. It really is good stuff.

I wish we had more folks using HPTuners on here. Would be great to interact with other Impala owners and learn from each other.

It does, your answers always cover every base, I thank you for that.

I've been eyeing the tuner for a bit and reading up on it in these forums. I remember in one thread, people were talking about using an 87 tune (for 87 octane gas) and a 93 tune, etc etc.

I think the overkill would be the best option after buying the tuner. I seen in one of your posts how you mentioned you compared his changes to your stock file to see what he modified. I can see myself doing that as well.

Thanks again Jtrosky!

jtrosky HPTuners is simply a tool that allows you to modify the tune in your vehicle. It does not come with any tunes for any vehicle - it just allows you to modify your tune.

That being said, there are a few tunes available in their user-supplied "tune repository". These are tunes that other uses have modified and have submitted. There is no "safety" or "sanity" checks on these tunes whatsoever there, so it can be risky to apply them without thoroughly reviewing them first.

What year/engine is your vehicle (I don't remember from the top of my head)?

Also, you can always but the Overkill tune from Overkill - he charges $150 to take your stock tune file and modify it - which you can then apply with HPTuners. The $150 fee is assuming you already have an HPTuner. If you are looking for performance, that is probably your best option - unless you are willing to spend a LOT of time researching how to modify the tune yourself (takes a LOT of effort, time and testing). You *really* have to know what you are doing if you want to modify the tune for best performance.

Hope that helps.

kamikazeedriver Are there any out of the box tunes available with the HPTuner package that are relatively safe tunes but still effective over stock?

No - with HPTuners, the tunes are never actually stored on the HPTuner device directly. The HPTuner hardware is just an interface used between the software on a laptop and the car's OBD-II port. The tunes themselves are just stored in files on the laptop.

The Pro version of the HPTuner hardware allows you to datalog to the device itself whereas the Standard version requires that you use a laptop to datalog...

The Pro version also supports external sensors (such as a wideband O2 sensor) - although nowadays, there are widebands that just connect to the laptop via USB, so that is not such a big deal anymore...

Obviously, you have to be very careful and only change things that you fully understand - you don't want to blow up your engine. :-) I've spend a LOT of time doing research on the HPTuners forum (and asking questions).

As far as I know, you can't modify the tune with the AutoCal device at all.

And yes, with the HPTuner package, you can edit your tune on a PC "remotely" and then just "apply" it to the car when ready. HPTuners also has a fantastic scanner application for reviewing datalogs. Very, very powerful software.

jtrosky Yeah, that's one of the things I also modified on my 2012 - changing when the TCC locks/unlocks to avoid those "bog" situations. If you've already purchased the Overkill Autocal solution, I'm sure that he can modify that for you (if not already done in his tune). But it definitely is nice to be able to do that kind of stuff yourself instead of relying on someone else to tweak things... I must have modified my exact shift points, TCC lock/unlock speeds and other trans parameters dozens of times to get them "just right" (for my driving styles). :-) With the HPTuner, it literally takes less than a minute to update the tune parameters once you connect it to the car.

Joes74challenger Yeah the only thing i really wanted to tweak was when overdrive comes in. I want to bump it about 5mph later on my 4 speed as it tends to bog a bit. On a slight incline it goes into overdrive and you can feel it lugging a bit as the rpms are right at 1000 or 1500 rpm (can't remember which it was at this point which it was). If they didn't shift but about 5mph later i think the issue would be much improved

Joes74challenger I know it will still apply and remove the tube but now I'm bummed out i didn't get the controller i thought i was. I guess i didn't think there was that big of a difference between them. Can i just open and tweak the settings on my pc? I'm in IT so i think i could do it fine, just not sure if there is an app to do so already or not.

Oh well - if you do ever decide to get an HPTuner (the $350 mentioned above is long gone already), you can just read the Overkill tune from the car since you will have already applied it with Autocal).

I still modify my tune from time to time trying to "perfect" the shifting to my preferences. :-)

After seeing your post yesterday, I messaged him to make sure everything was included, since the picture lacked the whole kit, and then never got back to buy it.

Between errands and painting my brake parts, I got sidetracked and it then was gone.


Do I even need a vendor tune to get started or is it easy enough to just start tuning on my own, using the HPT forum for tips?

You program/edit the HPT from a laptop, then just plug the HPT into the car to reflash, right? IOW, can I program remotely/away from the car, then just plug the HPT into the car to download that program?
04-23-2017 06:42 AM
jtrosky My understanding of the AutoCal device is that it simply allows you to "apply" a custom tune - not modify it yourself. I think it also lets you datalog and read/clear codes too. But what it does NOT allow you to do it modify the tune - just apply it and datalog.

With an HPTuner, you can do all of that, plus you can actually modify the tune yourself. It's really a whole different ballgame in terms of functionality....

Either way (AutoCal + Overkill Tune or HPTuner + Overkill Tune), you'd still end up with the same Overkill tune (although, I think the HPTuner version of the Overkill tune allows a few "extras" that you can't get with the AutoCal version) - it's just that if you go the HPTuner route, you can also modify the Overkill tune yourself - or design your own custom tune (which is what I ended up doing - I don't even use the Overkill tune).
