    If you are searching for a better tool than a multimeter to diagnose O2's and crank sensors and MAF signals, there are some cheap Oscopes on the market now. No more $2,000 scopes!

    Anyway, I had no idea that scopes were this cheap now.

    (I have no connection to this company or to the retailer - for informational purposes only)

    I just bought an Actron 9190 scanner for $250. Does ODBI on USA cars as well. It allows you to display O2 sensors etc as well as read and clear codes. Does not do ABS and Airbag systems and doesn't work on pre 1996 imports. Cheapest one that would do ABS was $800. Liked the Auto Xray one as well but it needed a laptop and I didn't feel like lending out my laptop any time one of my friends wanted to use it.

    Details below:

    OBD I and OBD II enhanced and CAN scan tool CP9190 Trilingual Elite AutoScanner Pro offers DIYers and technicians the features they asked for. Upgraded features include the ability to read domestic enhanced codes, graph engine data, record and playback stored vehicle information, and the ability to print information through a PC. All this in a tool compatible with ALL 1996 and newer OBD II compliant vehicles as well as certain pre-1996 GM, Ford and Chrysler vehicles. All Actron code readers and scan tools are CAN compliant.

    Product Features

    OBD II enhanced codes (1996 and newer domestic vehicles)
    DTC Lookup Services for further help

    thanks no-doubt. I've got the ST-05 and I'm thinking of getting the new Launch X-431 for the non-exotic cars.

    DIY'ers have progressed. Way back in the day we just had a test light (voltage or no voltage). Then we upgraded to multimeters (actual voltage levels, resistance measurements).


    Now we can buy Oscopes for $120 that give us voltage signal waveforms (useful for seeing if a crank sensor is correctly detecting cam position)...something for which a multimeter or test light is comparitively useless.

    That is cheap.....single channel it looks like, but still I didn't know there was anything out there that cheap.

    I've got a fluke 120 which in nicer, but a wee bit more expensive.......

    The Flukes are such high quality...plus they have a better display screen and data line protection from stooges like me putting the electrical probe onto something that I'm not supposed to, and they may have a higher sampling rate, I'd guess. Anyway, the Fluke scopes are easily the choice for anyone in the business.

    ...but for a simple home DoItYourselfer, better to have a cheap $120 Oscope than no Oscope at all (since most DIY'ers aren't going to run out to spend $1,500 on a Fluke).

    I would have gone for the $120 version too were it availbable a few years ago when I was shopping. I will say that having 2 channels and some storage has come in very handy (main and cam triggers on the screen at the same time), but over all saving money would have come in more handy :)

    Agreed; nevertheless I was kind of annoyed, when I purchased my Fluke Multimeter and saw, what was imprinted on the back. Made in China .... for that money.

    Best Regards from Germany

    when an SD-1 or SD-2 systems text editor was either not appropriate and non-applicable(Marelli version logarithmic/speed density Fuel management...288/F-40), I've used a $9(nine!) dollar, analog, volt meter from radio shack... and a 2 channel, ANALOG-yes, guages with the needles-o-scope....Sanyo....as I recall...it was $100.00 at fry's electronics in 1985???
    I used lab stuff in the 1980s....so the cost was not really fair to compare...but you all are correct...

    It is not the cost of the book,
    but the value of the information which lies there-in....

    Sd-3s have 8 year "time bombs" in them from date of first power up...has anyone found a hack/mod to defeat this yet?
    $15-20,000.00 for a text editor which will be a doorstop in 8 years is just plain Rong....

    Just for some general clarity:

    1. Multi-meters (voltmeters) measure voltage and resistance (some can also read current)
    2. Oscopes measure waves (oscillating voltage patterns)
    3. SD-2's and SD-3's are proprietary engine computer readers/programmers/testers
    4. OBD2 scanners are engine computer readers (some can clear error codes, too)

    Each of the above are different. They are used for different purposes on different aspects of cars.

    Number four should be 4a and 4b. There are ODB2 code readers which just read the codes and maybe clear them and there are ODB2 Scanners which not only read the codes but also display live data from the different engine management sensors as well as PIDs and IM and other functions.

    Along the catagory of 4b: OT-1 from Innovate Motorsports. Just ordered it this week so I haven't played with it yet. An interface between the obd port and an laptop. Reads and resets codes and logs data on 60? parameters. Only $150 and the site is
    tuneyourengine.com

    Probably play with it on my mercedes or truck. FWIW
