2012 Camaro ECM Secrets Revealed
For 2012, GM has already re-written their software in the E38 ECM to comply with the new EPA/DOT regulations that will come into effect in 2014. This is about when you will see the new Gen of Direct injection motors that are currently racing in The Grand Am series (C-6 Corvette) begin to come on line. OK we are not going to reveal all of the secrets because VaraRam spent a lot of time and money in R&D to find them all. We are just going to show one very significant change. They say a picture is worth 1000 words so here is a video of one of the changes on a 2012 Camaro, Don’t try this if you have a 2010-2011 Camaro only 2012 on up . This is an across the board change so ZL-1’s Corvettes, Chevy Gas Trucks etc…all have the same alteration. So, if someone tells you that there are no changes to the computer, just have them watch the video. We have driven over 1000 miles with this unhooked, tried it on ZL-1’s and some trucks etc.. they all drove great and ran hard with clean fuel trims in some cases better AFR’s than OEM stock. If the check engine light had never come on you would never have known this was unhooked. Our research and development programs here at VaraRam are intensive to say the least. We stay in touch with manufacturers to stay up to date with the latest changes from the OEM’s. This enables VaraRam to produce the very best performing product possible to our customers. We hope this informs and opens a few eyebrows. VR Tech |

are they running wideband O2 sensors now and adjusting air/fuel trims that way vs MAF tuning? or am i completely off?

Sooo what exactly are you trying to say? The car runs with the MAF unplugged? Or did I miss something else here?
Any why not do this on a 2010-11? I accidently didn't plug the MAF back in on a dyno run back in April with my 2010, closed the hood, made the pull car ran fine, put down similar numbers as with the MAF plugged in... The AFR was the same as with it plugged in, and the check engine light didn't even come on. Open the hood, "Oh look I forgot to plug the MAF in", plug it in, make another run, again similar numbers, similar AFR... Now again, I didn't do this on purpose, but it seems like nothing new to me. |

We do not want to dive to far into this because this video is but one of many. Its the many that are allowing us to push both flow and power higher. Understandably we don't want to reveal too much here. We have spent a lot of time and money in R&D to develop the 2012 camaro system, we prefer to keep some things quiet.

The reason the other intakes/ram airs do not have a problem with the ECU has nothing to do with their architecture. In terms of airflow being delivered to the engine ,It’s as simple as this “They are restrictive” simple as that, their MAF sensor depth and or placement has been altered as has the bore diameter of the intake tubing ,so most make some power. Some make power from flow and some from computer reading alterations and some from both. That does not mean they offer a flow increase over OEM. Some are behind and some are ahead but they do not support the stock engine in terms of its true flow requirement. All the talk about this design vs. that design, yet they cannot flow over 273CFM on a stock cylinder head at 28 inches of water@ .500inch of lift. They may have told you that their systems flow whatever CFM. That may be true mounted to a flow bench but not mounted to a throttle body, mounted to an intake manifold, mounted to a cylinder head. That is a different world and a different aerodynamic flow package.
We have all of the systems, we have flow tested and road/track tested them all,and we data log and catalogue the results. We even modify their systems to find where to improve their products performance.Each time we have done this we have found substantial power and performance gains over what they delivered right out of the box. On one popular cold air unit we found another 12hp and 15ftlbs in only 5 min! With another system, a Ram air system, we found it had very poor efficiency. This system Incurred over 80% pressure loss. When we made it into a proper system the drivability was lost. To make it what we produce everything would have to change or we could just do what they did and leave it restrictive. The above listed ram air systems manifold pressure was only 13.9 -14.0 PSI@ 5650RPM. The stock air box is at a rock solid 14.10PSI+ at the same RPM, yet the aftermarket system will run slightly better than OEM stock . This is from MAF manipulation, it's not from actual generated air flow. Anyone can and should data log it for themselves. If you cannot support the stock heads flow requirement, how do you expect to support a modified one? GM didn’t want you to touch their car and for that reason the ECM and the stock airbox are within the engines flow requirement. They do not meet it by 100% but they are close. GM is not stupid they do a real good job of engineering these vehicles. For 2012 to make big power from flow they have changed the way in which you have to go about it. We will not say any more than that, we are happy letting our competition think whatever they want because on race day the guy with the VaraRam will be the one holding the trophy. We have posted a video in another thread to show one of the many changes that were made for 2012 |

So whens your 2012 cold air available?

No, still factory NB 02's. Sorry. Had to install an Innovate LC-1 WB to tune mine.

http://www.camaro5.com/forums/showpo...4&postcount=15 I was hoping to see the blowing on the MAF and killing the engine video. Has anyone with a 2012 tried that yet?

So what's this a hybrid sd/MAF style system? Lol
