HHR Intakes

This post was to get a 2.2L HHR to test. CGS has already done this now.
#2 - The HHR's ECM automatically adjusts timing and air fuel mixture based on the available airflow. No addiditonal "mapping" is required. There are several things you can modify with aftermarket "tuners" (like removing the neutral rev limiter, the speed limiter, changing shift points, etc.) - but the ECM handles all the specifics a lightly modified engine needs.
You can always buy a CGS intake if you want to improve your performance!
Do your own research... listening to one opnion isn't enough... The truth is out there!!!!!
Please people don't be misled... the stock ECM will handle general air/fuel mixture and timing to the stock setup.. but now that you have change to a high flow exhaust & now air intake your ECM can't handle those adjustments.... Why do you think in the form to fillout they ask what you've done to your vehicle... because they can make the proper adjustments to the ECM based on the vehicle modifications... here are a few tuners that will tell the same story.... Why do I hear some of you saying your MPG has increased ? ---- your vehicle is running leaner now... (less gas) which in turn is heating your valves hotter than usual...

It's kind of true. I think for small mods like CAIs and muffler swaps the stock program should work fine even though a programmer can optimize your factory settings to take full advantage of your mods. If you where doing something large like a supercharger them no doubt you are going to need new programming. I had a Diablo Sports flip chip on my Mustang, it had three positions you could change it to. They were factory tune, high performance tune, and custom tune. I had to have the custom tune on my chip updated a few times. The first time I had them program it with my CAI and cat-back setup. Then I sent it back for a retune when I put in a lower temperature thermostat so the fan would work correctly with the thermostat. Then I sent it back for a third tune when I added shorty headers.

Why is is then, that with the CGS intake I'm seeing temps 2-4 degrees cooler than stock?
Oh I remember now; - BECAUSE THE ECM COMPENSATES FOR IT!
Henry, spend some time in the automotive world will you???
