Now I have T2 and I want boost @1bar but the ignition modul cuts off ignition at 0,7
someone told me that my problem can be solved easly by puting in or out resistor in ignition module
can anybody help me?

During the Winter i will put:
Garrett GT17 @1bar
T5 370ccm fuel

As you are lousing up your motor management anyway by mounting different turbo's and injectors without taking into account mixture and ignition timing control I may as well give you a recipe for preventing the ECU from protecting your motor, because that is why the ignition is cut off.
In the EZ210K find resistor R207 and remove it from its pins. Replace it with two resistors of 1K and 3K9 in series, the 1K on the pin nearest to the connector.
Then connect a zener diode of 2V7 between the connection point of the two resistors and pin 7 of either one of the two IC's marked CD40106, whichever suits you best.
The cathode (black ring) of the zener should be connected to the resistor joint.
Now the ECU will never "see" a boost it is not happy with and your problem is solved.

The thread Glasgowjim is referring to is going to be an endless discussion about a messed up connection of wires and pipes to the boost control solenoid and the diaphragm valve and as such has little to do with your post.

I want to emphatically point out that this recipe has nothing to do with my mod, it is a stand-alone operation in a situation far from original and, as such, undesirable.
