I have a completely stock 2008 HHR SS automatic, I have HP tuners pro suite and recently purchased the credits for my HHR.

I am not trying to tune it, I only want to keep an eye on things. Here's some things that kind of bothered me.

TPS 12% at idle, P,R,N,D Is this normal
02 sensors were dead flat?
Emissions readiness never went to complete?
When driving on the freeway doing 65 and the cruise on, the rpms stay right at 2,000rpms? This seems high to me, my S-10 would only run 1,500rpms in the same situation.

No check engine light, scanned for codes and nothing came up. This is my first ecotec motor, so I don't know what is normal and what is not. Thanks for any help!

 

Rpm's are about right....different gearing then your truck

 

Thanks for the response, I tried to research it on google but it seems not too many people use HPT on these HHR's. I tried downloaded a stock HHR SS tune out of the HPT repository, but it keeps closing before it's done loading. I asked the chevy dealer about the TPS, and they wanted to hook it up to the Tech 2 loL!! I will just wait till I get my manuals and then I will be able to figure it out.

 

You may not have your logger setup for the LNF. Do you have the beta update from hptuners? I can email you a file I use to data log.
