Plus make changes lets say that the gas gauge is off. If it says the tank is 90% full, I can change it to a different value. Same lets say if speedo is off.
Should be interesting to test this pro version and see what sneaky things I can do.
I'll go into depth on this with those of you coming to the test/tune this Saturday.

BTW I wll be writing a monthly column for a new magazine related to the Corvette and they will be at our test/tune day this Saturday for a photo shoot so shave ;)

even more functions

In testing the Ease Pro version scanner I find not only can I see within the PCM but also.

BCM - body control modules
DDM- driver door module
PDM- passenger door module
HVAC- climate control panel
IPC- instrument panel control
Radio
MSM- memory seat module
RFA- remote function actuator
SDM- sensing diagnostic module
ABS- anti-lock braking system

thus you have nowhere to hide, we can see all ..... :)

Plus it also works with all C4 MYs, and if you have Ford, Dodge or toyota, the same unit scans all their models.
So one scanner gives you lots ok snooping power.
Today I used it to tell PCM to shut down the cags and its light.

Sounds cool

John,

Sounds very cool, but can you elaborate a bit? Does it actually allow you to save PCM modifications into flash, i.e. disabling cags, changing fan turn on/off temps etc? Or are these on/off settings only temporary, that is only while EASE is connected to the car?

You also said it works on all C4s (including my '85) Does it come with two cables, or is the C4 cable extra?

Thanks

This looks nice. thanks for the info. Will the pro version allow you to turn your fans on at the strip when you want? will it turn off the CAGS? etc.. Are these functions only supported when the scanner is pluged in? or do they stay after you remove it? Whats the price range of the Pro version? Thanks for the info.

But wait, there's more questions:D

For the PDA version, does it offer all the same features or is it downscaled?

How much is the pro version vs. the regular version of EASE? If I understand correctly the main difference is that with the pro version you can access more info, but you can program (turn on/off) with both versions if you get a GM specific one.

Re: Sounds cool

Being its a test tool and not a re-programer of the PCM software itself, the scanner is changing a value in PCM memory and thus when car is turned off, the change would be gone.
Its man purpose is to test a function by turning that function on or off.
But that still can be nive to have lets say at the race track and you want the fan relays forced on.

Ease makes different versions of the pro version that depending on the model you buy allows the car types of that model(s) to be used.
So if you buy a OBD-II version only.
then no C4 using OBD-I would link, you could later on add a option to then also allows OBD-I (C4s) or buy a higher model that includes both ECM and PCMs.

The model I am testing now is the big daddy, does all American nameplates, both OBD versions, bi-directional, data logger and monitoring all other electronics in the car.

The Pocket P/C version I am also testing is neat but the pro version allows a bunch more functions to be monitored.

The PDA or pocket P/C models do generic OBD-II where any of the desk/lap top versions also do the enhanced, which gives many more functions then what EPA requires.

The PDA & PPCs scan and record, you can then store and replay the recording.
Ease is working on a enhanced version for thpse two units so they will be close to what the laptop personal enchanced version does.

As to what Ease charges, the personal enhanced version is 350 ( any models I can get you a 10% discount) and the Pro version starts around $700 and goes as much as $2,000 for a balls out, every option version.

The Personal enhanced version is what most of us use and does as a scanner "Read Only" no bidirectional, but Ease allows people to pay less on upgrading as people want to add more features.

You can mix and match the feaures/options you want, Ease then just gives you a new access code that turns those features on within the same model.

Thanks John!

It is really good to have a member with your knowledge of PCM's and scan tools here at Z06.com!
Sorry to be redundant, (I left similar questions on another thread you posted on)
What are, and how many componants are needed to make the changes / read the PCM?
If these pieces are left hooked up, when the key is turned off, do you loose the changed settings?
When removed, do all settings go back to a default mode?
What is needed to interface the recordings to a home based PC?
To get that special price, do we have to join the ZR1 team at your site?
Thanks again:)
:cheers:

To Scan / Monitor a PCM you need some type of P/C, either PDA, pocket P/C, laptop or worse case a desktop P/C.
You get a PCM interface cable that connects to the serial com port of P/C and the DLC connector under the dash.
As far as changes, not sure what you mean but as to the pro version of Ease scanner, the same parts are used, some type of P/C and the interface cable.


If these pieces are left hooked up, when the key is turned off, do you loose the changed settings?

Remember, with the scanner you are not rewriting the PCM software, the scanner is poking a different value into PCM memory where a function resides while the PCM is on, thus as soon as the key is turned off the PCM RAM is cleared and so is the temp change. Think of what the pro version is a tech test tool allowing tech to turn functions in another state to test to see how that function responds. This allows the car to be driven and monotor how that function is doing with this change but when engine is shut down, that test change is cleared out.

When removed, do all settings go back to a default mode?

Yes, when the car is turned off, all RAM is cleared and next time car is started new values from PCM software put its coded values back in. Think of this as a poke into PCM RAM by the scanner.
If your looking to re-write PCM code, there are a few vendors who will be selling such a product within a few months, so they say that will allow you to custom re-calibrate PCM functions


What is needed to interface the recordings to a home based PC?

No difference, as long as the desktop has a serial com port ( if you only have a USB port then you have to get a USB to serial cable from Ease) you install your Ease scanner software also on that P/C.

To get that special price, do we have to join the ZR1 team at your site?

Team ZR-1 has never charged any money for being a teammate, we are not some club, we're a team of hardcore Corvette owners of all model years, helping each other enjoy the car, thus your welcome to be a teammate, if not ,
as team charter says, we help all in Corvette family and thus, no you do not need to be a teammate, I'll still get you the discount a teammate would get.


Thanks again:)
:cheers:
Quite Welcome
