Overclock ECU...

Now that the cams were installed i was curious to know if there was a way to increase the limiter or remove it.. And turns out there is..

It has been called "Overclocking the ECU", as it speeds up the processing of the ecu, thus 'overclocking'

So i found some info on it, and decided to give it a go.!

(This is for a 4efe, but same thing applies)

All that is done, is changing the frequency crystal that is inside the ECU.
Standard the ECU has a 4Mhz crystal, and at Jaycar i could only find a 4.4Mhz. (But if a smaller or larger one could be sourced, that could be used too)

Instead of replacing the crystal completely i installed a switch so i can change between them if needed.
And since its dyno day Tuesday, i can actually see if its going to make a difference or not..
