Wtf is a crystal mod?
Lets you rev to higher RPMOriginally Posted by Flyineunos
It's been a few years, but, If I'm not mistaken, You overclock the ECU with a different crystal, changing the clock frequency. It brings the redline to 8000
Excerpt from Loren's Miata Blog "Invisible Sun" .
...I spent 40 cents on a 4.43 MHz crystal to replace the stock 4.0 MHz crystal. The math says this will raise the rev limit from 6900 to 7642 rpm. When the crystal arrived in the mail, I spent about 2 minutes soldering it in and... bingo! $100 mod for 40 cents.
The downside of this mod is that it also changes the frequency that the ECU uses to connect to an OBD scanner to display fault codes and diagnostic info. The OBD scanner can't deal with that and won't connect. Not a huge deal... until you need some diagnostic info. I figured I'd try to do something about it.
So, I ordered some more parts and experimented with a switching circuit that would allow me to switch between two crystals. It worked! Today, I just finished doing a final install of that switching circuit. Now, all I have to do is reach behind the passenger seat (where the ECU is located) and flip a switch to go from the stock OBD scanner compatible mode to the extended rev limit mode. Cool!
