I did Ben's speed limiter mod today and wired it to a switch. I turned the switch on because I heard that after about 15 minutes, the check engine light would come on. If it did, I would know the mod worked. Well I drove around for about 20 minutes, and the CEL did NOT come on. I am now very confused. I previously tested the switch the make sure the circuit was wired correctly and that "on" was on and "off" was off, and it worked fine. I am pretty sure that I did the mod correctly, but why isn't the light on? Is it my car or what? BTW I have a 95 GLE. Any ideas? Thanks.

 

.........yor car didnt have the rev limiter to start with

 

uhh, ya it did. GLEs and GXEs are limited to like 117mph. This is a SPEED limiter, not a revv.

 

O ..... so even the gxe's with the comfort and convenience package are limited to 120??

 

im not sure about them, I think they are the only exception other than the SE's of course

 

GLEs arent limited.

Plus, the only way to know if the mod workes is to try it. Go faster then 120mph. Sheesh...
