    Has anyone purchased and used the OBD2 software? Is it worth the price? How does it work?

    Look back at post 228 from rocko7. He claims to have had an Alpine 6 cd changer that works with the radio installed. Model CHMS 620

    I ordered my base Suburban with trailering, traction and 4.10 on April 18. I just got my order "number", DHRSK6, with TPW of May 14. I'll have it before June! Pretty fast service.

    After supposedly installing reprogramming with the tech2 and then checking the computer programing on another dealers computer the read out on tire size showed that the new tire size was installed. (Stock 245/75 vs. new 265/75) The reason I claim that it did not really take is by checking the odometer over a known mileage check. The odometer was not correct until I used the hypertech reprograming.
    The set up requires that you carefully mark your tire then roll one turn and measure the distance then divide by 3.1416 to obtain the true diameter which is input into the program in 1/4" selections. A 1 inch diff.in circumferance of a tire with aprox. 8foot cir. would make a differance of 55 feet in one mile.

    Though the cold air is probably not a problem for those with the Auto Htr/AC controls now it will be come below 50 degree weather. Your dealer does supposedly have a supplement fix for this problem now. My fix was arbitration and GM buy-back. They paid me 2 May and am now proud owner of a Toyota Sequoia.

    Let us know when toyota buy's back your sequoia because of Ticking and vibration problems.

    Can you let me know one more time how you fixed the wheel size. Did the tech 2 do the trick or did you have to use somthing else/ Thanks Bob

    Just bought a new 2001 Suburban 4WD LS with several other options of which the Premium Ride Suspension is one. Does anyone have any idea what the make up of the suspension is vs the standard suspension. I assume the shock absorbers are part of the mix; any other differences?
  • lambdaprolambdapro Posts: 51
    Self leveling rear shock absorbers plus 265/70R16 tires instead of 245/75R16.

    Have ordered a copy of GMT01CK8 Shop Manuals. If no one answers you in the next ten days I will be glad to research this for you. Will look for a simple way to defeat the automatic lumbar support inflation. I`ll watch this area since someone may post an answer in the next day or ten.
    Helm advises my four volumes is in shipping dept. now. My guess is 6 to 10 days deliver time.

    It took the hypertech programmer to get the odometer correct; mph difference between 245's and 265's is small enough that you won't see much differance on the speedo even at 75mph, thats less than 3mph.

    Let me know when the differential whine in your Yukon XL requires it to be replaced. It also was required in my ex unit. Best of luck to all.

    A 1/4" diameter tire change is definitely noticeable in the speedo/odo. As Ryan said -- If you're outside the range of what GM supplied as stock, you'll need something like the HP-III to calibrate correctly. Also helps for fine tuning between tire brands.

    I understand a 1/4 inch tire change may be noticeable, but my point is that it has to be something GM planned for in its programming. The tires that came with my truck have 16/32 of tread when new. Presumably when the truck was assembled the computer was set for the tires that came from the factory. As I wear these tires down (which is happening quite quickly) I will wear nearly a half inch off the tread depth before they are worn out. As I approach that worn out stage, I will have worn over 3/4 of an inch off the tire diameter. If a 1/4 inch difference is a reason to recalibrate, shouldn't the computer be recalibrated every 10k miles or so to adjust for the tire wear? Or, if GM expects there to be a 3/4 inch diameter change over the lifetime of the tire, then why should I get overly worried about going from an OEM tire with a 30.6 diameter (Firestone Steeltex A/T 245/75/16) to one with a 31.3 (B.F. Goodrich All-Terrain T/A 275/70/16)? I am not so concerned about the speedo or odometer as I can deal with that, I am more concerned with the ABS or any other "safety" related parameter.
  • I have visited this area several times since I started looking for a new minivan or SUV, and have found good info here. Now I would like to give back a little. I live in northern VA and just bought a LT with autoride.

    In northern VA just about everyone is selling for about invoice. I telephone interviewed 12 dealers: 5 were unresponsive or thought unreliable for one reason or another, and the other 7, with some work, were from invoice to invoice + 200. Yukon XLs seem to run a bit higher, but I did investigated them as thoroughly.

    The out the door price includes more than invoice, and some dealers played games with what invoice means. The invoice separately states the vehicle total (model+trim+acc, which of course you can calculate on your own), the cooperative advertisement fee, and the delivery freight charge. Line 310 of the invoice includes freight and coop advertising. Coop advertising is 1% of MSRP less freight so its about $400. Freight is $765 here. One dealer quoted a price of "invoice less $1000" plus freight, taxes, documentation, but used the 310 line for "invoice," thereby charging twice for freight. That and a very high doc fee, in addition to purposeful deception, erased any advantage.

    In the numbers above I used the line 310 definition of invoice. In addition to that, doc fees are added (range 89 to 290, reasonable amount seems to be 150) and tag charges (about $49, which you can do on your own). Some try to stick you with "business license tax" - about $60.

    Anyway, it's all negotiable, and it's out the door price (line 310 amount + docs + anything else) that matters. Around here I found that an out the out the door price of invoice (line 310) + $200 for EVERYTHING excluding sales tax, is clearly attainable.

    In addition, as others here have mention, GM gives a $1000 rebate for former owners. Also $400 grad discount -- maybe some others.

    By the way, the line 310 amount of the invoice is not the dealer cost, and the 3% holdback is not all the dealer earns on a car. Read the notes on the invoice. So, don't get caught up in the empathy play some dealers use - I'm only earning $200 on this car, salesman needs to get a commission, etc.

    Interestingly, I looked into the BBB record of the dealers and found good correlation between BBB rating the dealer's level of dealing straight.

    I just purchased a Suburban 4WD, and want to add skid plates -- did not find a vehicle with that option and all the others I wanted.
    Does anyone have info on this -- aftermarket vendor, pricing, is the vehicle pre-drilled, how many plates are there?
    When I spoke to the dealer, it seemed extremely expensive - $500-700 - relative to the option price.
    Any help appreciated,

    I just bought a Suburban, and am having lots of fun trying to figure everything out. One thing I noticed, the oil pressure gauge indicates about 60 to 70 psi when driving, about 45 when idling. It jumps around a bit when driving. I am used to a lower psi - any comments?
    I read somewhere that the middle seat head rests fold back when the middle seat is folded up for more cargo space. But the version I have does not seem to let the head rests fold back, and therefore requires one to move the front seats forward. Are the head rests supposed to fold back?

    thanks,

    I was informed friday that my Z71 shipped from the factory to the "upfitter's" on April 27th. My question is, how long from the time yours left the factory until you took delivery?
  • vixvix Posts: 4
    Has any one purchased the detailed GM repair manuals for their Suburban? Is there a cheaper way to get these shop manuals?

    My eddie Bauer expedition lease just expired so I was dying for the truck. Talked the dealer into going and getting it off the train myself...literally..and driving it to the dealer (63 miles) so they could wash it, inspect it and redeliver it to me. Pre delivery inspection was not done, so takes these comments as interesting but not indicative of how the truck was really delivered AFTER the PDI done by the dealer. Probs--Steering wheel turned off center to the left, play in steering of one inch; RR door wouldnt unlock or open from inside or out; compass/temp buttons on mirror were hooked together and did the identical thing instead of their discrete functions; cassette player on invoice with upgraded radio--but the cassette player not there; But what a truck!! Great smooth ride, much smoother than my 99 expedition 4x4.....quiet as a mouse. Gorgeous inside. I couldnt be happier....even if I got to see some things the mexican assembly folks screwed up that i wasnt supposed to see.
