At this stage it is assumed that you have followed Getting Started and have setup your Folder(s) where to Save your Calibrations.
A Calibration can be opened form 3 sources.
The first source is from file, ie. From the calibrations stored in the Path List that either come with Kalmaker, or calibrations you have saved and stored.
The second source is from floppy disc, ie, from a disc that has a calibration saved on it in Kalmaker format.
The third source is from your SRAM on the RT Board in the ECM
These are explained in this sequence below.
Opening a Calibration from File In Getting Started we have already opened a calibration from file by selecting Buffer 1, then Read, then KAL3\BIN. and we chose BAYA (VN V8 Group A ) as a calibration.
We can now use this as our base calibration and modify this as required. A calibration can be modified either online or offline. i.e. Linked or not Linked. Obviously to get the best results we need to be Linked and calibrating in Real Time.
Opening a Calibration from Floppy Disc If you have saved a calibration on disc or have received a disc from us, you can open it by first inserting disc after opening Kalmaker, then select Buffer 1, then select read, then select TYPE IT from the Path List. Next the Enter Path Specification box will appear with C:\KAL3\*.* displayed in it.
Simply type A:\*.* over it . A List of Contents of the disc will now show. Select the appropriate file.
Opening a Calibration from your SRAM This may sound a bit odd but there are times when you may have to do this. It is usually because you have either mixed up experimental calibrations and you can't remember which one is which, or you have deleted this calibration from your Laptop, so the best bet is to upload the calibration in the SRAM back to the Laptop.
To do this select Buffer 1, then select Link, then select All >> to PC ( Calibration Receive). You can only do this in Buffer 1. A sliding scale will appear showing the rate of transfer. When complete you can either Save it or compare it to other calibrations by first opening a calibration in Buffer 2 and then select Buffer 1 (or 2) and then select Diff to Screen. More on this later……...
Loading a Calibration To Calibrate in Real Time we must Transfer the Calibration we opened in our Laptop into the ECM. This is stored in the SRAM on the RT Board inside the ECM.
Note Each time we change to a different calibration in our Laptop, we must Transfer it to the ECM if we want the engine to run on that calibration.
Once you've chosen and opened a Base Calibration, to Transfer (Load) that Calibration, you first must be Linked. See Getting Started .
Next, select Buffer 1, then Link, then ECM<<PC ( Calibration Transfer or Transmit). A sliding scale graph will appear showing the rate of transfer. When complete you will be ready to start calibrating in Real Time.
To make changes to the calibration select Buffer 1, then select Edit. The Cal Variables list will now show similar to Page 3 of "a look at calibrating".
Next scroll down to No. 124, FUL:OUT:VE and either double click or Okay. This will show you part of the Fuel Map as shown on Page 4 of above. Click on 3D of that screen and it will show you the 3D of that map as shown on Page 5.
There will be more details on calibrating in later sections
Saving a Calibration Now that you have a calibration open, and only if you have made changes you will have to Save Changes or Discard. You can either save them when it suits you, or when you try to exit or change to another calibration. If you wish to Save voluntary you can select Buffer 1 and then select Write. If you wish to either Exit and then either Quit or open another calibration, a box will drop down stating that "Buffer has been modified". Save or Discard. If you Discard then obviously all the changes won't be saved which is great when experimenting and you totally stuff it up…….
If you either Save this way or Write voluntary, the Calibration Save Size box will now appear asking what size you want to make the calibration. VN - VP Holden are saved on 16k eproms, VR-VS manual trans are saved on 32k and all VR-VS automatics are saved on 64k.
Basically it doesn't matter which size you save to. If you have an Eprom burner and you have 64k eproms in stock save it to 64k. If you want us to burn your calibration on an eprom for you, save it to 64k as that is the size we stock. You can either email or send us the calibration on disc.
When you've selected the size and clicked OK the Path List will appear again. Remember, this is where you opened the cal from. Now double click on the folder you want to save it in eg. Holden.
The "Enter File Specification " box will now appear with C:\KAL3\HOLDEN\ written in it. That's if you chose Holden…
Note If you forget the name of the calibration you are working on, don't panic, because if you look at the bottom of the screen you will notice that it is written there for you to copy. Remember earlier we opened BAYA as our example so it would read C:\KAL3\BIN\BAYA at the bottom. Whenever you open a file, that file is always displayed at the bottom of screen, whether it be in Buffer 1 or Buffer 2. Keep an eye on this……..
Note It doesn't matter whether you use upper or lower case lettering.
Now let's call our calibration JOHNSV8. Our display would have to read C:\KAL\HOLDEN\JOHNSV8
It is also good practice to start writing .BIN after our Cal names. Eg. C:\KAL\HOLDEN\JOHNSV8.BIN
The reason for this is that when you start burning eproms the Eprom burner calls these files Binaries and unless you call them .BIN in your Path File the Eprom Burner software won't be able to find any cals. Notice that the factory cals are stored in a folder called BIN. This isn't a bin or trash bin. It means they are binaries.
When you have typed your calibration name press Enter . Another Mission Complete…….
Finally if and when you reopen this calibration ( JOHNSV8) and you make more changes to it, you will have to repeat the above process and check at the bottom of screen that you have called it the same name ( that is unless you want to call it another name, maybe JOHNSV8A for a different version) and when you press enter you will be asked "This buffer already exists. Do you wish to Overwrite?" Select Yes and you're done.
That completes Opening, Loading and Saving a Calibration.
