Hi there!!!

I am tuning my H22a1 using an AEM EMS, I tried on the AEM forum but they are kind of not getting me anywhere. So, this is my question:

How much volts have to show the Knock sensor to get a real detonation?

I am actually using the OEM (original) sensor that comes with the H22a1, so I hope that someone can help me. I am treating 2.95volts as SEVERE detonation, so my tuning map is extra safe.
But I want to have concrete information to tune my engine as it should :D.

My second question is:

I found (JDM BB4) H22A cams on ebay, this are the OEM to, I want to gain more power, but: Is this a great upgrade to H22a1 or I should put the Euro R or Type S cams instead?

My engine is stock, I only have straight 2.5" muffler and direct air intake + aem ems ECU , and balance shaft removal. I want to buy some cams, these are cheap $55, but if I am not going to gain many HP & TQ I don't want to waist money on thing are not going to help.

Thanks in advance.

If some one have an EURO R camshafts set or Type S for sale, please tell me :D

 

The stock JDM cams are either very similar or exactly the same as the USDM cams, so save your money there. The Euro-R and Type-S are the same cam, and you need the matching valve train and need to have your valve guides checked with the cams installed.

 

Thanks, I will think a little bit more about the cams.
And by chance don't you know about the knock sensor!?

Thanks
