IK20 or IK22

[meg_omen]

heat will increase during compression, so if increase compression the amount of heat generated in the combustion chamber increases thus increase the chances of detonation. this heat will cause pre-ignition(actual term) where spark produce not by the plug itself.
few options to play:-
- plug heat range, up 1 point... still depending on the ratio increase
- add more fuel... can cool down the chamber abit
- fuel ron... if normally using ron95 then try ron97 otherwise need to add octane booster
- increase IG timing... to compensate the actual spark against spark created by the compression process

roughly that explain it... good luck...:proud:

coz all this can be google up... if you're into technical, browse the forum...

sorry... should have write 're-tune' instead...
fuh, one of the reason I seldom contribute to people questions...:stupid:

Haha... no worries bro. We are all in the same league here.

reviving old thread;

between ik 20 and ik22, + normal ecu;

a) no tuning to ignition timing?
b) only feel up to 'kaki'?

appreciate sifu's feedback

Kind Regards,

20 equivalent to 6 heat range, 22 is 7 which is colder. What heat range do you require?

Dear Sifo's;

Its heat range 6 = bkr6eix

and the most important info;

How to check, the NGK igniter OEM or counterfeit product?

Kind regards

Then better use IK20.
