Carbs for the 4AG

[SutteR]

Than isn't it only about the fuel pressure regulator?

The documentation of this ignition system is available only in Hungarian language so you will have some problems with it. I'd be glad help you out with some basic translation but I don't have any time for it yet... (have to learn for my exams)

If you find some online translator or something you may can use some information: http://www.roxel.webzona.hu

With MAP sensor we can use the vgc120, totally changing the stock ignition we can use igc60. This costs about $80-90.

OK, I don't want to learn...I translate some of the description of the IGC60...

1. The system can be used for 4 cylinder / distributor engines and works with regular Hall generator or compatible.
2. 24000 sparks/min max, which is 12000rpm at a 4 cylinder engine.
3. The rpm range is divided into 60 parts: 650/min...9500/min, in 150rpm steps.
4. The wanted ignition degrees (???) are freely programmable in this range.
5. The pre-ignition (???) can be adjusted between 0,5-63,5 degrees in ,5 degree steps.
6. The closing time (???) is programmable between 0,8-10 ms.
7. The opening time (???) is programmable between 0,2-2 ms.
8. The parameters can be edited in an excel sheet or with a Windows based program. The data can be transmitted via the COM port.

Optional features:

... (not for us...)
e) The rpm range and the intervals can be set (by factory) custom: in the range of 600-12000rpm.
f) Optional output for a shift signal. (The wanted rpm is programmable)
...
h) With IGN-tuner you can tune your ignition on the brake pad or on the street.
