Ed Wright has been retired for years now, only works from his home and only on a appt only basis. With that, you cant use a separate ECM on the on the LT1 cars. GM closed that loophole years ago. All modules are VIN tied now, you cant swap the ECM without connection to the GM Global system and syncing the module and flashing the firmware on file that GM has for that VIN as the ECM's come brand new with no OS loaded onto them now.

Would this be possible, or would this "secondary" ECM have to be "introduced" to the other xCMs (I.e. BCM, TCM, Etc.) in the vehicle using GM remote servers? Then in case of Warranty issues, simply swap back to the stock ECM, dismantle all the aftermarket Hardware, Etc. and come to the dealer "squeaky clean" If it would only be possible to "introduce" a tuned ECM to the rest of the vehicle's xCMs somehow without having to connect to the GM Global servers, this would be a great solution for any aftermarket tuned application. |

Any time a module is changed out the dealer has to "marry" the modules in their system again, they are not plug and play swappable.
Believe me, GM has been on these forums for years watching quietly and learning how people have got around their systems. They get smarter each generation to try and keep people from being able to get around the system.

Ideally, there should be an aftermarket company/ies specializing in "marrying" / "Introducing" and "re-introducing" the modules back. When there is a will there is a way... |

The other problem is if there is a powertrain related failure associated with a CEL there will be no CEL or freezeframe to reference. Further, when they up load the PCM GM will see something wrong with the mileage reported and what the PCM says. You'll notice engine hours are also recorded and displayed on the DIC. People have tried this dual PCM thing with no success, even when it was easier. |

Damn technology. So marry a new one and tune it. Swap when you need to and yes cam needs tune. Ed got 335 WHP out of my hotcam with SLP 2OTL and those awful SLP headers.
I'm waiting if anyone decipher or recall 2OTL.

I am guessing you just missed what we said, it isnt possible to have 2 ECM's and swap back and forth. There is absolutely no benefit from it, I mean unless you want to spend the $200 for the blank ECM, then pay the dealer to load the OS onto it and sync it to the vehicle, then spend the $200 to tune it and then pay the dealer to re-sync the ECM every time you want to swap back and forth which will be noted on the VIN history for your vehicle at the dealer each time they do the work.

i'm running a 116 LSA with my TSP cam "Cam Specs: 235/239, .645"/.635", 116 LSA" and it's pretty choppy. chek out my youtube channel and you'll hear the car idle pretty crazy. might change your mind after watching

This is not correct...the hot cam has +1.5 degrees of overlap. It will have a noticeably choppy idle over a stock lt1 cam which only has -29.5 degrees of overlap even though both cams have the same lsa. You cant judge a cam by lsa alone. 116 is a popular lsa on VVT cams be cause of the computer controlled cam timing. If you do a zero degree lock out and disable VVT then you will notice the LSA drop down into the 112 range.

If there only would be a way to overcome this "marriage process" and whenever a swap back to the stock ECM is made, then all the details (Incl. engine hours, Etc. are updated in that ECM) line up again, just as if no swap has ever been performed. I would assume that if some computer tech guys put their heads together, then such solution could be done. This would open up so many excellent business opportunities for the aftermarket tuning arena. |

I really don’t like cams with such high lift. It’s what has prevented me from getting a cam for so long. I like the idea of the GM heads and cam kit because of that. I know it can’t make the same power as many aftermarket setups but, with such low lift and seemingly slow ramp rates, it should be a cam you could run with solid springs for ages.

For a street car driven many miles a year, a milder lift cam is a good idea. The high lift cams make the most power for the duration, but like everything else there's a trade off with wear and maintenance. Fast. Inexpensive. Reliable. You can only have two.

I know on LS stuff anything over .600 lift caused side loading with a stock style rocker. Not sure if the same issue applies to gen 5 heads but I would suspect so with the 1.8 rocker ratio. That being said lift alone isn't the deciding factor in longevity of a valve train. The intensity of the cam lobe and type of valve springs play a big factor too.
I do agree a mild lobe cam with lift under .600 that can be controlled with lower pressure valvespring is best for a street engine that is going to see a lot of miles.

My whole thing is, get the GM heads/cam kit and do a very mild mill of the GM heads. Granted, I understand that effectively changes some aspects but, I do believe that it would not only net gains but still provide the longevity some of us are after.
