I am using Autocal on a 2.2L 2009 with VVT and no problems. The ECM is not able to to flip through any tunes as the tune must be loaded to the ECM. It is not a piggy-back device. While I can't promote it here, my business website does sell these things as well as other vendors. I own a performance shop and have a professional tuner that figured out the 2.2L VVT. I am just starting to document it in this section on a post earlier tonight. Pretty cool wake up call as I just tried it out tonight!

 

Ive had a tuner (SSkev) hook up HPT and verified all the relevant tables were editable, so it is doable, just not listed on the site.

 

just ordered my Jet Stage 2 Module cant wait to try it out!

 

Quick try and get your money back! It did zero for our car! Ended up selling it to another HHR owner and getting a personalized Trifecta Tune !

Best Mod to our Guttless 2.4 we've done to Date .....

 

I recieved my Jet Power Module friday and installed it in about 5 mins. I did notice a difference right away it pulls harder at 2k then ever befor and me and my coworker who drives a pt cruiser race every once in awhile for sh*ts n giggs and as usual i win. Well i raced him saturday after runnin out my 87 octane and filled up with BP 93 (jet strongly suggets running high octane) and i didnt just beat him, i gained car lengths on him, so theres my noticable difference i give it

 

did he tune yours?

 

not yet, I just wanted to know if he could do it with hpt. As you say, its not listed but he is confident that he can do it. Now I just need the time to get my hhr off the road to install the sc, then get him to tune it. He prefers doing a dyno tune at a shop in oakville.

 

ya ive been in contact with him so he said hes gona test mine for a reading too...how much is that cs project costing you? id love to do that but i dont have the smarts/how-to for it haha

 

Trifecta is the way to go

 

For tuning I would say your best bet is either HP tuners or take it to a dyno shop. In my experience trifecta was terrible. Their customer service sucked and their tune was dangerously lean. You better off having someone to program the car in the car as opposed to 1000 miles away. If you do dyno tune it make sure the shop has the proper software to do it because the shop I went to needed to wait a week to get their software.
