What is the correct tool?

I'm actually not sure what tool would be best. Mine were gapped by a friend that works at a dealership.

 

I would guess that he probably used something like this:

i use one of these. yes iridium ones are more sensitive, but honestly, just dont smash it against the ground and you should be fine.

 

I tried using a cheap gapping tool, but the plug was too strong for it. The tool just bent before the anode would budge..

 

That tool you linked...how are you supposed to use that to install them, not nearly long enough.

 

The tool is used to set the gap of the plug. You use a regular spark plug wrench or socket to actually install them.

 

But this gaping spark plugs i have no idea about it. Didnt have very much time to read this thread rather than just skim it until now so Gernby im gunna be taking a look at those charts. Funny how this changed into my old spark plug thread....

What are the advatanged over the Greddy Manager than the Hondata?

 

Ummm ... I think there was a miscommunication somewhere. Unless you drive your S2000 very short distances in cold weather, where it won't reach normal operating temperatures, then you would NEVER need HOTTER plugs than stock. Since you live in a hot climate, you are likely to need COLD plugs.

The advantage of the Greddy eManage is that it is much cheaper, and probably easier to install. However, the most important thing is that you find a tuner BEFORE you order it. You need a tuner that is experienced with the platform you choose.

 

A lot of information you are asking about. Has been covered. Do some searching on the forums and you will find what you need.
