Some one get s How-to- on this for us that want to learn how to do it our self's

 

OK so we goit the part number for the correct harness now. The part number is .... 15411879. It is also for the 05 2.2 Malibu Classics as well. Hope this should help you guys out in the quest for more power. You can check Jonyyl's other forum Cobaltss.net under the 2.4 performance forum for more info. There is a guy there named Psykosteve who does the tuning here in AZ and will get a tune for your ECM and ship it to you as well! The guys on there are also selling their stock injectors for around $50 shipped to anyone that wants them! Good luck to all and happy modding!!

 

do you know steve personally cause i want him to email a tune to someone so he can just upload it, because he doesn't know how to tune

 

yes I have met steve several times and he is a part of our Cobalt group in AZ. Just shoot him a PM on Cobaltss.net and tell him Jason with the HHR sent ya!

 

We can rescale for the injectors with the tune ...But I have to say the scanner in HP isn't always spot on .. Although the stock injectors are only good for 192 hp at the crank ...Duty cycle is great to referance to but since when are the intake valves open 80% of the time ? I do believe any one doing internals or more then CAI,Exhaust,Header should upgrade them . If you guys want I can get a price for the injectors and harness ...

 

I have the cold air intake. I have a cat back sys. I need the tune and injector swap. How much? and where near Oklahoma City? This type of information is great. Thanks to all working this mod.

 

I'm bumping this because with my nitro, I'm running lean.

Anyone got part numbers for the injectors?

Anyone done this to their 2.4 HHR and how is it performing?

 

so whats the deal? Can you not tune a 2.2L HHR LS? Lame for me then!

 

Were can we go for a tune in So. Cal.?

 

Ill sell you a set $25 shipped, I dont need them.
