Initial Cadillac XLR Hptuners Scanner setup

Tonight I setup my test laptop with HP Tuners in the 2007 Cadillac XLR to see if it would all play together — with some success.

I used the scanner profile that is setup for my 2008 STS-V,  which makes for good comparison but perhaps higher scales than the XLR needs.  The XLR was well heat soaked, and it was warm here in Texas still even though evening time.  Intake air was 95 F outside, 100 F coming into the engine, and 135 F in the manifold.   Plano is at 600 ft elevation above sea level.

What I see in this initial scan is a) it works at all and b) the XLR PCM calculated that the engine output was around 301 hp in 1st gear at 5734 rpm. It stayed around 300 hp from there to when it shifted.   The XLR LH2 V8 is rated at 320 hp at 6400 rpm under ideal test conditions at sea level, 70 F etc.

Max first gear calculated torque was 290 lb ft at 4572 RPM.  The LH2 is rated at 315 lb ft of torque at 4400 rpm under SAE test conditions.

On first blush, I am pleased that I got the test gear working, and the HP tuners can talk to the XLR,and I can capture data and post it.  Now I can study what it means lol.

Cadillac ATS Entertainment & the Apple iPhone

Last evening we found that enjoying songs from an Apple iPhone on the Cadillac ATS Entertainment system by Bose requires that you know one thing — who is in control?

We are enjoying a test drive of a 2014 Cadillac ATS Premium model courtesy of Crest Cadillac of Plano, Texas.  Please see 2014 Cadillac ATS Test Drive and Buying a Cadillac ATS, Wife Version for more info on this test.

On a drive last evening we selected what seemed a simple task:  plug an iPhone in via USB to the Cadillac ATS and enjoy playing music from the iPhone.

In the big picture, this immediately appeared to work, simple and easy.  The entertainment recognized the iPhone as an iPod (wrong, but okay), and when we selected music to play on the iPhone, music played through the Cadillac ATS’ entertainment system.

Then we noted that the correct Artist and Song info, although visible on the iPhone, was not always visible on the ATS entertainment system (showed no artist found).  There was a place for it to show — and I should take a moment to share that I love that entertainment has become so interactive so that we can use a phone as a song database and play it in the car — but the place it should show the info shared that it didn’t know the info even through it was clear the iPhone did know.

If we selected Browse songs, it would pause for a while, then allow us to browse by Artist, or Album.  But if we selected a song on Browse, it would begin to rapidly sequence through songs, playing only a snippet then going to the next song (as if in Seek mode).

We tried a different iPhone, with different result — the song data was visible, showing Artist and Album, etc., and the music played properly from browse.

Then we closed the iPhone music player on the first iPhone, plugged it back in, and — not making any selections on the iPhone — used the Cadillac ATS entertainment system to select which song to play.  Now the song and artist information showed correctly from the first Apple iPhone as well, and everything worked as expected.

Lesson Learned?

Don’t try to control the iPhone from both the iPhone screen and the ATS entertainment system screen at the same time — just plug in the iPhone (without music playing) and then use the ATS Entertainment system touch screen to control it.

Meanwhile, the Cadillac ATS continues to impress.  We had a lovely evening out, and are enjoying the light, agile sports sedan.

 

2014 Cadillac ATS Test Drive

Crest Cadillac was kind enough to send over a new 2014 Cadillac ATS Premium for my Wife and I for a real-world Cadillac ATS test to make sure it would be a good fit as a next car for her.  Please read my post, Buying a Cadillac ATS, Wife Version for background.

The gallery above are iphone pics on  an overcast day.  The actual shade of the car visually is more like the exterior paint shown in the shot of the interior.  This one has a black interior as opposed to the Morello two-tone, but my Wife notes that the Morello is of interest to me and not to the perspective owner.

She approved the shade of Red, and grabbed up the key fob to wheel us off to breakfast.  The magnetic suspension dealt with everything we threw at it with aplomb.

After breakfast my friend and I took the ATS over to BJ’s Brewhouse in Allen, then to Sam’s Club in Plano.  The ATS’ trunk had plenty of room for more supplies if needed.

This example is a 2014 Cadillac ATS Premium with the 3.6L DOHC VVT DI V6.  Although some reports have suggested this engine has a hint of harshness, it seems perfectly smooth to me.  The ATS doesn’t have the core grunt that my Supercharged STS-V V8 does, but it has very competent acceleration and gets much better gas mileage.

My Wife’s first impressions are “Gotta have it” good.  Next we’ll take it out and around a bit more, and let her test the entertainment and infotainment features.
