Спасибо, я это уже сделал. Только результата не заметил 

нужно идти дальше, мозги включенные под катализатор 470 Ом игнорируют. я бы даже сказал -- резистор совсем не нужен, нужен коротыш между В и С.
The RON plugs come in nine different colours:
Resistance Value   RON plug colour & Octane rating
Zero ohms   Blue 95, Black 91
220 ohms   Brown 95, Black 95
470 ohms   Brown 98
750 ohms   Green 98, White 98, Orange 91
1200 ohms   Green 95 (part No. 90276398)
2200 ohms   Yellow 95, White 95, Violet 98
4700 ohms   Red 98 (part No. 90276399)
Meg ohms (Infinity)   Violet 95, Red 95, Orange 95, Yellow 91, Blue 91
So a 'Blue 95' RON plug is used with 95 Octane fuel or higher. You need to make sure that the octane rating of the fuel you use is at least as high as the number on the octane plug else you can damage your engine. As long as you keep to the above rule, the higher the number the better.
What are the fuel octane values?
Fuel = Octane:
Super Unleaded = 98 Octane.
Four Star (Leaded) = 98 Octane. 
97 Unleaded = 97 Octane.
LRP = 97 Octane. 
Premium Unleaded = 95 Octane.
Unleaded (and Two Star) = 91 Octane.
The table below shows the changes made by each resistance value-Vs-Octane rating for the three basic 8 valve engines, which where:-
1 = Basic value.
2 = Idle speed increase by 100rpm.
3 = +5% fuel acceleration enrichment.
4 = +5% fuel enrichment throughout range.
5 = Ignition retarded by 5deg throughout rev/load range.
2.0 NE non-cat   Resistance Value:
91 Ron   zero ohms = 1
Infinity ohms = 2
95 Ron   220 ohms = 1
1200 ohms = 3/4
2200 ohms = 2
4700 ohms = 2/3/4
750 ohms = 2/3/4/5
98 Ron   470 ohms =1
