I'll be swapping out my de with the ze very soon, and want to make sure I have my ducks in a row. I've been researching for days on here and still have some lingering questions. I understand you can use the kl31 and kl36 (in big letters). I've read that the 31 was originally for the mtx but looks for an extra coolant sensor thus causing one fan to activate all the time. Is this true and if so is there a way to correct? My seccond question is with the speed limiter. I will be installing a gps which uses the speed sensor. Will pulling the speed sensor wire to the ecu interfere with this?
