Default New with a question

Hello,

I'm new to the forum and have a question on my 06 SS Impala. Before I ask, I’ve gained a wealth of knowledge from your posts and wanted to thank you all. I have high flow air boxes or filters as well as tuning (handheld only at this time) on my other vehicles. I have the K&N setup on my 04 Silverado and it’s louder than I prefer as my foot is normally pretty heavy. Based on what I’d read, I went with the CAI box on the SS and was very pleased with the install (no wobbling or line up issues) and seat of the pants feel. The CAI box is no where near as loud as the K&N. Under WOT and higher RPM, it sounds good. I was going to add a MAF, but I’ll be returning it to Summit. The MAF I got based on part # from Granatelli (350128-C 2006 Chevrolet Impala SS LS1 - Black w/Cold Air Tuning - also listed the SS Monte). On the box it says Z06 and both ends are way too big for the stock elbow and filter that came with the CAI box. I was also ready to get the Diablo Tuner but am going to wait until the latest tunes are posted.

I have noticed that after the air box was installed there was short lived period where the DOD did surge a bit while changing from 8 to 4.

After all that, here’s my question: I’d like to adjust the headlamp aim on the Impala. I saw nothing in the manual and don’t want to mess anything up.

Thanks.

surge comes from the trq mngmt being taken out of the engine. nothing major. won't hurt anything, you get used to it.

there should be an adjustment on the back of the housing for the lights.

Thanks, I'll take another look. The surge I referred to was a jump in RPM which I could not really feel. I’m guessing the torque management is what caused the jam the breaks kind of feeling. I turned off the traction control, nailed it (not in a perfectly straight line) when it took off and then nose dived, recovered, then paused like it ran out of fuel.

I’d love to turn that off.

I'm still wondering what that off the line/wheels turned/WOT power cutoff is from, I removed the 1st gear max torque limit in my car (HPT) and mine still does that. There has to be some other description for that 'feature'.

that has to do with excessive wheel spin, the abs kicks in and kills the fun. stability control in a sense. you can shut it off, turn tc/scs off, it will still do it. it's something built into the ecm that you can't get around unless you dig deep into it. it also saves the diff, and other things from going blamo.
unplug the abs sensors, pull the abs fuse, the scs fuse, and go have fun, but you also risking barfin the tranny

The headlight can be adjusted by turning the adjuster screws on the top. I think they're silver in color and hex or torx, iirc.

The top-left arrow is the only visible adjuster in this pic. I believe there is one more where one of the other two arrows are.

I think you are onto something there. Usually this happened only right off the line when turning since I got the car this summer. Yesterday with the cool weather increasing power and lessening traction, while going around a corner at maybe 20 I nailed it causing only one wheel to spin instead of the usual 2 wheels spinning like with going in a straight line...the throttle cut out. I believe if it senses one wheel spinning we have a differential saving feature in the PCM. I would turn off diff score protection and maybe abuse mode to try to can this, but I think this feature might actually be good as you really dont go any quicker with only one wheel spinning.

i don't recommend turning that feature off, it's there for saving the tranny from blowing the diff out. check out the v6 world. they blown diffs left and right due to one wheel spinning, IE around turns and such things. id just use foot control when going around corners

Thanks everyone for the input. I’m not going to attempt to deactivate the control, just trying to figure out when it's most likely to occur. I've read other posts about achieving the best launch at the strip but haven’t had a chance to go yet. The car only has a little over 1K on it. I traded in a 99 Chrysler 300 for the SS. It brings a grin every time I drive it and I want to get the most out of it I can.

stall it to 2300 rpms, roll into the gas slowly, you should be wot by the 60 ft mark
it takes a lot of practice

Hey Live2ride - you ever get a replacement MAF? Install it?

I did buy one but am returning it. The Granatelli site had one listed for the Impala and Monte SS, but when I got it (Same part number from Summit), the box says LS2. The mounting holes on the stock box are different and it won't work with the stock elbow or the filter that comes with CAI's cold air box.

Damn ... 2 strikes! Truly disappointing!

So you said the Gran doesn't work with the stock flex hose or have the same bolt patern as the stock box? You know the Gran part number that was on the part?

350128-C. The C was for Cold Air Intake.

I was kind of bummed also.
