CNK ECU success!!!!
Hi all,
Today I tuned Lostbouys Elantra Beta 2 on the dyno.... the CNK ECU solution works 100% correct, it controls the 550cc injectors perfectly.
I have however changed the method of control and kept it as a full piggy back system for fueling and ignition.
I installed the system at the ECU to avoid running wires into the engine bay. I basically intercept the signals going to the engine and modify them, then pass them back to the engine again with altered parameters.
Lostbouys car runs nicely - I tuned the engine rich for safety and only extracted 197KW (264HP)and 332NM from the engine at 0.6bar boost (+-8Psi)
of boost.
The car looses traction is first and second gear easily and I already had two run-ins with BMW M3's, which were totally anihilated.... wiggle_m
A little fine tuning and slight ECU alterations and I will be ready for the MAF systems in the US.
This same system will be used to convert MAF to MAP - AFFORDABLY and ALL parts with diagrams will be supplied! Costing for this ECU will be released very soon at $250.00 and has lambda, control, lambda monitoring (can display lambda just like an A/F ratiometer), boost control, extra injector output, 4 auxillary outputs, fullcontrol of MAP based ignition and fueling, Engine temp, Air Temp, Throttle position, it will use a 60-2 teeth pickup from the crankshaft, and be able to fire wasted spark coils....
Alot more functionality will be added at a later stage --- but thats a taste for now.
PS:- All those of you who have normally aspirated or forced induction engines ---- the CNK ECU solution is the way to go!!
Once I am happy with a MAF solution I will start a GB on this item and bring the price DOWN DOWN DOWN!!!

CNK Is it alright to give your e-mail to my tuning shop so they can talk to you about the ECU, as there are little enough Hyundai's in Northern Ireland never mind tuned ones, and as I plan to go turbo eventually, the ECU seems like the right place to start.

How does the piggy-back modifies ignition?
When do you expect the piggy back (with the MAF->MAP conversion) to be avalaible? The reason I ask is that I'm on hold to buy an s-afc2, but if I can get your device instead and it can control ignition too for a lower price, then I'd take that. I couldn't wait 3 months for your device tho... Anyway, got any estimation? Thanks Chris!

Barry - go right ahead ...
This ECU will work on ANY Hyundai engine, Beta1, 2, Accent, Elantra, Tiburon, Sonata, Santa-fe, etc Actually any engine from any manufacturer!
Argarwal - the ECU tee's into the stock wiring harness at the Siemens computer box - it intercepts the ignition and fueling pulses, along with the stock incoming and outgoing MAF signals and then from there will modify these via the real-time tuning software and then forwards the modifed signals back to the engine. For ignition the ECU uses the crank angle sensor signals to read in where the engine is at to then modify the ignition pulse to the coil. With a boosted engine, the MAP sensor is only used to read positive pressure (boost) and from that signal into the ECU allows you to retard or advance as you wish.
Fueling with Lostbouys car was done as follows:- I fitted his 550cc injectors, which are obviously too big to allow the car to idle with the stock ECU controlling them, so I made a few modifications to the intercepted injector duty cycle and open pulse, to get the engine to idle. Then I went into the fuel map on the dyno, and used minus figures to get the engine to run off boost, up till we got to the boosted area in the higher RPM range which I saw the engine wanted ALOT more fuel and we went into the positive numbers.
At the moment, the ECU will leave the stock MAF in place and control the engine around it's signals. I am working on the MAF to MAP conversion as we speak, I am waiting to get hold of wiring diagrams of the ECM connector from Random which will allow me to draw up a convesions diagram to MAP.
Right now the ECU is abe to control fuel on either MAP or MAF based systems, with leaving the original sensors in place. Yes the MAF will still max out at a certain air flow through it, (around 250 - 270WHP) depending on the size and flow of the turbocharger.... Once I have the MAF to MAP conversion sorted out then the power levels that the MAP sensor will handle will be disregarded and ANY power will be able to be made on these engines with no maxing out of sensors.
I will be including these into the kits from now on at no extra charge - the ECU will replace the 550cc injectors I usually supply in the kits as they are a discontinued SKU - read other post for details.

What MAP will you use? Something like a standard 2-3bar GM MAP?
Also, I would have thought that the actual firmware of the ECU in MAF vs MAP ECUs would have been different, meaning that a simple trick to plug in a MAP instead of the MAP wouldn't be too efficient. Wouldn't it be easy for you to just supply an additionnal MAP, and leave the stock ECU use the maf? Why does the stock ECU needs to see boost if it doesn't control fueling and ignition anymore?

Argarwal --
I supply a 2.5bar map sensor which will allow you to boost 1.5bar (22PSI) maximum positive pressure at the coast and 1.7bar maximum positive pressure at the reef. Positive pressure = pressure above atmospheric)
You cannot simply plug in a MAP sensor in place of the MAF --- the firmware IS different and the way that the sensors supply signal information to the ECU are totally different, and thereforewill not work.
I do let eht stock ECU use the MAF, BUT I intercept the signals sent to the stock ECU from the MAF and change the signal to "fool" the stock ECU into thinking there isn't enough fuel under boost, and this is how I get more fuel. There is no other way to fool the stock ECU to cupply more fuel with a piggy back system.
The Stock ECU doesn't see any boost at all, thats why the piggy back ECU is installed, ONLY the CNK ECU needs to see the boost, so that it knows when to fool th stock ECU to supply more fuel. The stock ECU operates as per normal controlling ALL fueling and Ignition events, just with fooled information from the CNK ECU.

What if your car is MAP? What is your solution on that? Also since you don't supply injectors anymore, can I use a low impendance Eclipse injector instead?

If your car is MAP - then there is a only a wiring difference. The ECU will still control it - lostbouys car is MAP and this is what I tested the ECU on first.
You can use any size injector you want. Just make sure it is large enough for yuor application so that you don't max out the injector and run lean.
