End quote. Install the map sensor is easy. I don't have the instructions at my fingertips,but I have DOC#'s. The orange/black wire for the map, They say it has a different color. That issue is easlily fixed be elimination of wires. The next step is the intake air psi and temp sensor on the lower pipe. the pitures on the instructions are showing the Solstice. But you can raise it on a lift and find it. On mine, when it was all said and done that pipe was completely out. The wiring issue can be summed up with two doc#s. HHr # is 1910765. This shows that the tan wire is the 5vref and the grey wire is the grd. The instructions say, and I've been told by the engineer over the phone that all the "pin terminals" are correct for both. Now pull up doc# 1913913 for the Pontiac. you will find that the map and intake psi sonsor share the 5vref and grd. Not so on the HHR. Also the gre wire is the 5vref and the tan is the grd. Now when hooked up in this way, the engine will not start. The ecm is seeing 20in of vac with key on or crank. Atleast that is what the gauge is telling me. So, I pulled up the schmatics on both and found the differences. Pulled the sensor off along with the pipe and swapped the grey and tan wires. It started immediatly. Now that is when I noticed the sensor not fitting flat. I ground a notch in the pipe for the extra plastic to sit and let the sensor be flat. Also they give you a metal screw to use to secure it. i used a screw that you will find holding evap cases together that is ment to secure into plastic not metal. I personally think it holds better. But What bill told me is to use a razor blade and cut the back notch off the sensor. That will probably work better unless you want to spend a few extra minutes pulling the pipe out. I recommend the razor blade idea. Then the programming. I talked to a guy at GM techline and did not have a good experience. I was also trying to finish this up on my lunch hour and was not sucessful. From what I hear on this site, I was the only one with issues on all levels of the install. Maybe someone else can chime in and give you something I left out. If you go into SPS with the MDI, you cant program the ecm using the VCI #. It doesnt have that option. Also when you program the ecm, you are also programming the ebcm. I went into the tcm to install the VCI. that seemed to work. After that, the car sstarted and was getting up to 15lb of boost. Took it to lunch today and did alittle showing off with the other techs and saw uppwards of 18-20. So, I'm impressed with this setup. Now I'll measure the fuel mpg and make sure I'm still getting good #'s. Check out those doc#'s Mike. Let us know the results. Thanks

Thanks for the compliment.
Eric, if yours does not go well, we will sell you a new Z06. How does that sound. Their not bad right now, in the low 70's... we have a yellow or a blue, your choice.
