CNK Fuel management system - Hyundai only
Hi all,
Yet another pleasing announcement which I'm sure you all will be very pleased to hear!
I have been designing a fuel management system which I intended to initially be a replacement for the old CNK extra injector controller --- I posted pics of this on a previous forum below.
Well this project has hit new heights and is now able to control 4, 6, 8, 10, or 12 injectors fully sequentially and in a stand alone mode - this is a first for CNK inthe electronic side of it's performance systems. The unit will be tested by the end of January.
I will release this product into the market with a group buy and the pricing will be DIRT cheap!! I expect tosell these at around $100.00 each for the group buy.

Chris!
How would you be able to program your mods onto YOUR new Fuel management system?
Would you have to hook it up onto a LAPTOP?
Also will it be able to program larger injetors(440cc) in a STAND ALONE MODE?
Will it have any COLD prevention faetures espically when you have larger injectors?
Thanks very much smile.gif smile.gif smile.gif

will it control timing?
will it adjust to boost?
MAf or MAP?
Dam... 100 bucks... this is dam good
4 injectors for non boost (stock injectors)
An extra 4 injectors for boost
an additional 4 for ThA NaWz

Here's the gist of this system guys --
The unit will be run stand alone, it is a fuel only computer for now --- until I am happy with how it works. I want to cover one step at a time and as the tests are completed successfully and I am happy (not very easy to do!) I will then move onto the other features like ignition control and boost control etc etc. First things first.
The unit will have a backlit LCD display as seen on the prvious post below these regarding the extra injector controller DIY kit. It also has program button on the LCD panel that you use to tune the engine from inside the car.
It is very simple -- it comprises of a table with RPM on the one end and boost in MAP(manifold pressure read from the MAP sensor included in the circuitry) and you tell the unit how much fuel in a percentage from 0 - 100% that you want the injector to fire. If you type in a value of 50% at 3000RPM and 0.5bar boost --- your injector will be running at a 50% duty cycle. This is as simple as it gets. Other features will be added at a later stage.
There are so many ways to install this product here is a way I would recommend using if you run turbo with a correctly build engine with a lowered compression. The way this is installed is as follows:-
A signal is taken from the crank pickup (60-2 teeth) by T-ing into the signal wire and ground. and then another signal is needed (for fully sequential only) which is taken from the camshaft sensor pickup, the unit then knows which cylinder to fire when. You disconnect your STOCK ECU from the injectors, (which ever injectors you are using) and you wire up the injectors to the CNK unit, the ignition section of the stock ECU remains stock.
The price for this setup is going to be dirt cheap ---- I know the product will work perfectly, and will be a piece of cake to install (easier than your everyday amplifier!) and tune aswell! Check out the link below and you will see pictures of the prototype unit.
