HP Tuner coming in tomorrow, What to do?

Hello all,

I was wondering if anyone had an HP Tuners tune that they could share with me or point me in the right direction. I am trying not to break the bank here so I am looking for DIY help or someone else's stock tune. I heard there is a tune repository but I have been unable to locate it.

Hello, the stock tune repository is located n the My-account devices area. Once you receive the HP-Tuner MPVi2 (I assume you bought this one) you register your device and you can access the HP repository of tunes -- there is a few for Solstice. While I own a 2008 GXP - manual -- there are 7 tunes there. there is little to no details on these tunes, I am ONLY looking at this for informational reasons. I would not 'load' these tunes to your car - -examine them in VCM editor and then compare them against your BASE tune -- once you export it with the MPVi2 tuner odb2 tool and then compare the data. I would HIGHLY recommend a qualified tuner to assist you on your first tine -- not something to just poke around like Martin at RPM good choice.

this is on HP tuners own web-site and forums -- the repository is reachable only after you register your device on their web-site in the my-account area.

Before you do what it appears you are trying to do you should read this page: https://www.hptuners.com/help/vcm_ed...activation.htm

The first step is to read, read, read. There is a ton of tutorial stuff on the HP Tuner site. I have printed about 50 pages and read and re-read them several times and am still not ready to modify a tune by myself.

The second step is to read your present tune. Save this as it contains your VIN and is the key to changing tunes.

Next step is to log a run. The run should include a few minutes of idling and a couple of WOT runs. Send this file and your orig tune to an experienced tuner. He (or she?) will look at the log and determine what changes need to be done. He (or she) will send back a modified tune that you can load into your ECM.

Steve, what are you trying to do? Are you having trouble with your supercharge tune? I've got my supercharger installed and tuned with Dave's tune but have a problem with it starting when the engine is warm.Dave has been working with me on this problem but has not figured it out yet.

Visit the HPtuner forums - I've been told that there's a large community base for these Ecotec engines. Ask questions, read and read more.

I paid Dave at PAW $375 for unlimited adjustments on his tune and I have 110% peace of mind that everything's all good. This guy's a wizard!

I suppose it's possible to load in a tune you "found" and have it bomb your engine. Take it from me, it's not worth it to melt an engine with a bad tune....After spending around $3,300 over the past two months I've finally got my car running again after bombing the engine back in April ($1,900 ATK engine, $299 MPVI2, $99 2 HPtuner credits, $375 tune to support the Opel injectors that the new engine came with, $525 PAW Intercooler (potential that metal was sent into the old intercooler after I melted a piston) $100 oil + oil filters, $30 antifreeze,

So......found an interesting gem in this car......If I am not mistaken, this is the 3 bar sensors right? if it is, it also isn't using an adapter so it may be a dealer installed GPP tune. How to I go to a stock based tune if I am already on a GMPP tune and don't have the original?

The car is not as peppy as I thought a tune would have made it. What else should I look for in this car?

My car is running fine with DDM's tune, although I have not found the time to log a run for him to look at. I am just trying to understand all the parameters that go into tuning so I bought an HP tuner rather than borrow one.

I trust you and Dave can solve your warm starting problem. Have you looked/listened for vacuum leaks?

Subtleties of ECM tuning

Following are three graphs that show some of the subtle differences in tunes. These are spark advance vs rpm vs air flow, just one on many that make a full tune.
First is a stock tune for an NA Solstice. Note the jaggedness.
Second is a performance tune. Note some of the values or boundary conditions are changed, but the graph is still jagged.
This is a more refined performance or dyno tune. Note the smoothness.

The 3-bar sensors were connected using either adapter plugs or by splicing the wires unless someone did something unique. Try looking inside the anti-chafe tubing.

Why do you want to go back to the stock tune? You would have to replace the sensors since the original tune won't work with those.

What octane fuel are you using? The GMPP tune will pull timing and reduce performance if you are getting knock from low-grade fuel.

Everything I read says that the GMPP tune restricts tuning options and is a different OS entirely with hidden tables and what people have referred to as more of a turbo nanny. I have the HPtuner in hand now and have pulled the tune. How do I figure out if it's been tuned by GM or otherwise? I'd like to go to a stock tune and just fix the sensor settings and see what the difference is.

Also, the fuel lid says premium required, so that's all it's ever gonna get from me.

ok, so if you have an actual sticker on your gas door, that means you have a tune.
( that sticker is not a stock item... )

If it looks GM-ish, then you could very well have the GMPP tune.

My 08 solstice base also had that sticker though? I'm pretty sure it didn't have a tune. I thought that was just because our engines are high compression or turbo'd?
