Turbo+/LH 2.4.x/EZ-116K/ pinout and modifications
Let's have a look at a modification which can change the statical ignition timing on part load.
The EZ-116K has two so called 'selector pins' (pin 18 and 19). By grounding these pins you will be able to modify the statical ignition timing - this means, that you will get a modified timing on part load. At cranking and full load at higher rpm's the timing will switch back automatically to stock values. Also it's not possible to switch the timing just in time - this means, the timing must be set before cranking.
And here is this EZK-mod (choose one mode or make it switchable):
- -6° retarded (connect pin 19 with pin 20)
- -3° retarded (connect pin 18 with pin 20)
- 0° default (nothing to do)
- +3° advanced (connect pin 18+19 with pin 20)
Update: In the meantime I'm not longer sure if this mod makes any sense!
I have recognized the maps from every chipable EZK and have noticed that all switchable maps within one binary are identical, so the question is:
What exactly does this mod do for us? Any further information would be welcome to add it here.
OK, now we come to a mod which works indeed in the real world :)
It's possible to extend your EZK with a EPROM-Board. I have done this mod to a turbo EZK-148 and to a n/a EZK-175, both are acting in the same way after chipping (i have chipped them with the stock '219' eprom from the Goldbox and with my optimized EZK chip).
After that it's possible to use the chipped n/a-EZK at a B230 turbo engine.
