Ok i posted this on *********** also (so forgive me for crossover thread). Im flying to L of Dallas on this friday to do my inspection on the black/black 6.0 all the easy stuff is done (agreeing on $ and sending deposit). Now the hard part...I was informed that when im there i should have them hook up computer and run a diagnostic report to show the following: 1) # of starts 2) max red line 3) time on engine 4) # of false starts 5) Max temperature range etc.... Ok..anything else? Now that being said, what am i looking for on all of the above? Lets just say the car has been redlined, do i walk away from it? thanx for the Help. MARK
Mark - What you're talking about is the LDAS report (Lamborghini Diagnostics and something-or-other). If you're having LoD do a full PPI, this would be part of it. If you're just going to look at it yourself, it would be worth having done. I would guess it's like most dealers where they'd charge you around $75 to hook up the laptop and run the report. The LDAS includes all the things you mentioned - time the motor has been running, time the ECUs have been running, % of time spent at each RPM level, last 10 highest RPMs (and duration), last 10 highest water temps (and duration), last 10 highest and lowest alternator voltages (and duration), last 10 highest and lowest cat temperatures (and duration), number of starting attempts, and a few other things. The report is done seperately for the two banks of the engine (and thus the two ECUs). I wouldn't worry about the car being redlined. After all, redline is designed to tell you the highest SAFE speed to run the motor. Now if the car was run at redline for 4 hours, that might tell you something about the driving habits of the previous owner. If the report tells you it was above redline, but only for 2 seconds, that's also not an instant fail. The thing I would be most concerned with on the LDAS is the water temperature reports. If the car has been often overheated or overheated once for an extended period of time, that would worry me since most of the motor is aluminum and the last thing you want to buy on the Diablo is a set of head gaskets, or worse, a head. Second most important would be the cat temperature history as this can indicate problems with the catalytic converters, o2 sensors, general engine tuning, etc. The alternator stuff is not a big deal. It's normal to have some pretty low readings since Diablos sit a lot and run down their battery. A few highs will sometimes come with that as the alternator works to recharge a low or damaged battery. The other thing I would look at is to see if most of the stats for the two banks are similar. They should be. I did see an LDAS report recently for a car in Australia where the info from the two banks were wildly different and one had a bunch of readings that made no sense. That's usually a bad sign - damaged ECU or something else screwy with the car. I had LoD do the PPI on my Diablo last year. Mike (their mechanic) was really terrific - he spent about 1/2 hour with me going over the report and explaining what everything meant and possible things it meant about the car and its previous use. That would definitely be worth paying for if you're not paying them already for a full PPI. Good luck! They are amazing cars.
