SSThunder Posted February 15, 2005 Report Share Posted February 15, 2005 PCMforless.com has this posted on their FAQ: Why should I add a 160° thermostat and LT-4 knock module? I know many people have the 160° thermostat, but do you have to have it if you get a custom tune? I'm guessing the LT-4 knock module is something I don't have to worry about. I've read many post on the PCM tune issue, but haven't seen anything about this. Hopefully I'll have a new custom tune by the end of next month.

DaGeorge Posted February 15, 2005 Report Share Posted February 15, 2005 The LT4 knock module was an upgrade for the LT1 PCM. The LT1 knock module was extremly over sensitive if you had any mods. The 160* Thermostat helps you engine run cooler, so you can run more timing and ect. Link to comment Share on other sites More sharing options...
