Hi,
New here, first post. I've had my '06 Z71 3.5l for a little over a year.
About a year ago, before I knew of this site and of "tuning", I bought a G Force chip.

Installed it, best I could tell it did nothing.

After coming here and reading a lot of threads and posts about tuning, I decided to get a tune from Lime-Swap.

In talking with Jeremy, I was convinced to "open" up the G Force.

Pictures are below.

Looks like it has something in there, resistors and a chip; but if one looks closer at the traces,
doesn't seem to be wired to be functional!

So here it is, for info or comments.

Not necessary to tell me I'm stupid or I wasted $69, :(

I would be interested in why I see G Force ads here, with all the negativity about such
"modules", with what appears to be good reason?

Interesting. I looked up that chip and found it can be had for $0.28 cents for one, and no doubt cheaper in bulk. That board does look bogus as far as that chip goes.

If not for this site I probably would have bought one of those also at some point in the past. This forum is a great resource for our trucks . . . it rocks!

From first glance it looks a lot like a "performance" chip that some drivers (back in my Cavalier days) used to put in their J-body vehicle (Cavalier, Sunfire) installed on the IAT connector. All it did was trick the computer into thinking the input air was extremely cold thus causing it to dump extra fuel. This was supposedly done to "increase horsepower and torque". Turns out inside the box was simply a resistor.

donv; Thanks for sacrificing your chip and...you're undoubtedly correct in its simplicity. Seems to be one to definitely remove from any recommendation list. Enjoy the new "real" tume fm Lime-Swap...I'll be doing the same when it gets a bit warmer to work on my truck outside.

:welcome2:



The ads that he's referring to are because of his browser history or stored cookies, fact it was sold has nothing to do with the ad content. Similar to people seeing Dodge or Ford ads on this page. Sometimes, people need to let it go.
thats why it has porn ads.....now I know

Hi Donv,
thanks for posting, I'm sure this will help other people.

Here's the note I sent giving my take on the guts:


Kudos to you for actually taking it apart!
And kudos to G-Force for taking deception to the next level, lol. The chip on the board is a digital latch used for logic circuits. Think of it as a series of 8 switches. If the device is powered up, and Input 1 has power, then output 1 will have power.
But the way it's connected on the PCB makes no sense. For instance 3 of the "outputs" are connected directly to the "power". Similarly several of the inputs are connected directly to ground. It's like plugging an extension cord into itself.
Furthermore, the "power" and "ground" circuits are spliced into your temperature sensor circuit. Net effect: zero.

I suspect that G-force chose the latch because it looks the part and it's cheap. But the fact that they custom made a PCB just for this? Wow, that's dedication. I would guess they spent ~$1000 in tooling on that PCB.

I get ads displayed every day that has nothing at all to do with my search history.

Perhaps the cookies that come from here are read and used for display. For instance, because I've read this thread, I have ad's for a chip.

I do also see things I have searched for, but not always. The other day I had an ad for motocross pants (I was looking), today I see ad's for a smart car.

Guys,
thanks for the responses.
I see now that G Force is offering $10 off and free shipping.

Anyone that wants this used one, I can make a real deal.
Half price, only $35, and no shipping- since it does nothing I won't ship it to you and thus will save the installation effort!:th_woot:
