LHU Swap question
Can anyone tell me if the dealer Turbo upgrade will work with my swap, I have a 2012 Regal GS LHU engine in my 2008 SS , I still have the factory LNF ecm .
My buddy works at the local Buick/GMC dealership and said the Colbalt/HHR SS/ Soltice turbo upgrade is still available, the price has gone up to $815, but his cost is $670 , any info is greatly appreciated. |
It should work since the upgrade comes from the reflash (retune) and you are still using your original ECM. But why do you want to go with this ? It is a very old , outdated and costly upgrade. On top of the high cost of that kit, you would also need the plug-n-play harness if that kit doesn't have it. Another $110 or so. Then you have to have the reflash done at the dealer. That's another $200 or so. The dealer has to get the reflash files sent to them from GM and that may be an issue. Those files originally came from the GM Performance Division. That department was dissolved several years ago, so even getting the reflash files could be a problem.
I would suggest looking into an aftermarket tune. It would be a lot cheaper and easier to work with. |
Check the ZZP site compare what is involved in the stage 2 upgrade

His buddy gave him a price, probably out-the-door.
That said, the GM tune wouldn't account for the upgraded fuel injectors, so ZZP may be a better option. You'd need the Bosch 3-bar TMAP sensors, with the plug and play adapters. You'd need to send them your ECM(and TCM, if applicable), either beforehand, so they can put the tune on it, or after, as a core. That's it. Is it a manual transmission? If so, how many miles are on the clutch? You may need a new one before applying a bunch more torque to it. |
Look into the ZZP site, they will reflash your ECU , they have the bosh 3 bar sensors, upgraded fuel injectors, and more! My point was to just compare parts in the kits!

He already has the upgraded injectors.

RJ, where did he confirm he has upgraded injectors? Are you thinking they came with the LHU ? |
