Diff. between ScanMaster v2.0 and v2.1?

[SpoolinUpGN]

The subject pretty much explains my question, I'm looking to buy a scan tool since I hear you're an idiot if you don't run one. Anyone care to tell me what the difference is because I'm looking to buy a used one. Also, what the heck does it do that makes it so important? I have 3 gauges (boost, oil pres. water temp) What does this do that makes it so special???

Oh btw, I want this to eventually become a 12-second STREET car, so maybe I dont need the new version of scan master?

Do a search on "scanmaster" and you can read for hours. You questions will be answered in detail in one of those posts.

scanmaster

Im not sure what the difference between the two is, im running a 2.1 version.

The most important thing to know with these units is it allows you to see the amount on KR (knock retart) you are getting.

A boost gauge will do this, but IMO a scanmaster is the least amount of equipment you need for one of these cars. You can read all the parameters that you would get with a scanner but its right there on your dash.

I run scanmaster all the time, and turbolink on my laptop so I can record engine parameters.

Start cranking up the boost with a scantool and you will soon be buying one.

Later,

my scanmaster manual says version 2.0 supports optional datastream Y and version 2.1 supports optional datastreams Y and W. i dont know what these mean. my friends who is really good with the tuning and computers for GNs said that the 2.1 has some minor differences like it can read O2 cross counts.

This is incorrect.

A boost gauge will NOT show knock retard. Knock retard is detonation and is mesaured in degrees (timing) which can ONLY be read by the computer.


The difference between 2.0 and 2.1 are a few things. First, 2.1 shows O2 cross counts (a number that the O2 sensor cycles). The 2.1 can read datastream W also. Datastream W is a "faster" stream than Y. It will display the value on your scanmaster more times per second that the 2.0 will. The 2.0 is actually quite slow compared to the fast update.

close,

2.1 will show cross counts with slow update chips.

2.1 will work with W data streams.

W and Y data streams are the same update rate (pretty much) W shows IAC and cross counts (Y does not)

This will help clear up the datastream questions...

An important point....if you want a "non-standard" data stream, your chip guy will need to know when he burns the chip. Also notice that the fast update ALDL data streams are not compatible with the old version of Turbolink. I think the latest Windoze version of TL is compatible though.

So in order for me to be able to get High speed 02's, PL (injector Pulse) and SP (Spark advance) It would have to be programed into the chip by the programer?

I have the 2.1 version.

Stupid question but "W" isn't one of the plugs on the ALDL is it?

knock gauge

Pardon me,

My typing fingers got away from me. That was supposed to be Knock Gauge.

NO W and Y designates the data in the stream. Some things are lost in order to display other things more often.

Turbojorge,

Yes...you will need to tell you chip guy which data stream you want and he will burn it in the chip. Look at the web page I linked to and you'll see what each data stream option shows.

i.e. "W" data has the fast update on 02 mV and Knock Retard...it must be used with Scanmaster 2.1....since you're changing the ALDL data to get the fast update, TurboLink and OTC monitors won't work...also notice that you'll miss the Malfunction codes with the "W" data stream.

Only so much data can come out of the ALDL port. If you want the fast update there will be some give and take.

Personally I run the Scanmaster with a standard ALDL data stream chip (no fast update). The SM shows me everything I need when I'm driving around on the street. When I get to the track, I plug in my $50 laptop and use the old DOS version of Turbolink to record my runs. But I'm not running 10 second 1/4 miles either...

You were correct previously John ... TurboLink v3.x WILL work with all the ScanMaster custom data streams (X, Y, W, Z). The DOS version doesn't.

Just to clarify...

Another nice advantage of the Scanmaster, IMO, is that it also works as a multifunction gauge. In addition to showing KR and O2 volts, it is also:

--a voltmeter
--a speedometer
--a tachometer
--an intake temperature gauge
--a coolant temparature gauge

And that's just what I can remember. Granted, none of these readings update as fast as a regular gauge, but it's a good compromise if you want more information behind the wheel. I went with a SM because I wanted more information but didn't want to spend a ton of money on gauges and cover my dash with tack-on gauge pods.

I have a sm2.1,boost/vac gauge,oil pressure gauge,knock gauge and a tach.other than egt its about all covered
