Kalmaker is the only Real Time fully programmable software for Delco engine management computers worldwide. It features full diagnostics, much more detailed than the factory diagnostic data stream, which also means more detailed than other diagnostic software available.
It also has full datalog capabilties for backtracking over fault finding.
Our latest addition is integrated wide band datalogging, which shows Commanded Air Fuel Ratio and Actual AFR. On top of this it features complete self tuning in Closed Loop and Open Loop.
At this stage we are using the Autronics Wide Band Meter system using the Bosch Sensor, which is the same setup as used on Dyno Dynamics Dynometers.
These pages are here for all Kalmaker user's and are here for those interested in EFI in general and of course those interested in purchasing Kalmaker Software. See Intro to Kalmaker

If you wish to learn more about Delco computers, the place to look is in the genuine factory workshop manuals, in fact,
The Biggest and Most Useful Tip that I can give you on this Website is,
go buy yourself, The Genuine GM Holden Workshop Manual for VP Commodore, either Volume 3, for V6 (M40320C)  or Volume 4, for 5L V8 Engine Part No. M40320D. These are the Engine Management manuals, and  should be called "Understanding the Delco 808"
I have recently found out that these are no longer available from Holden Dealers, but are still available from Bookworks.
To order, phone 1 800 252 116 or email sales@bookworks.com.au and quote the part no. above.
This is the best $69 you'll ever spend
This book will save you $1000's, and teach you every purpose of each function, including wiring diagrams, and fault diagnosis.
GM are the only company I know of that explain in detail how their vehicles work, in particular, their EFI.

It is impossible to send Manuals or Demo Software for potential buyers, so these pages should be enough to whet the appetite and show you some of the Kalmaker, and in particular, the Street pro 3 capabilities.

The Street Pro 3 Package includes very detailed Manuals and takes some serious reading to digest.
Reading the manuals is essential, and we do offer Email Help Desk, and General Enquiries. 
These Pages serve only as a supplement to the Manuals and its aim is to get you up and running quicker and written in such a manner that beginners can comprehend.
We here at Injection Connection are constantly building the Help and Technical Section pages.
