Has anyone here used the J & S safegaurd on a there car? I know in my old car, every one that was making good numbers were useing one of these.
Here's the link to there site
Please tell me if you think that this could be used on are cars.

 

Never heard of that product before, however it seams simple enough.

 

Your PCM already does this, thats what your low octane spark tables are for

 

No one else has any thing to say about this?

 

hes right...the cars PCM already retards timing if knock is detected...

 

if your using an aftermarket ECU then its great!!

but our stock computers do a very decent job...
