Boost referenced retard and knock retard with externally switchable additional retard. Now you can run full timing off boost or off nitrous and still have retard, and no more than is needed, to run boost or nitrous

I ran a vehicle specific unit from this company on my wifes supercharged 350Z, this one is universal.

I emailed John and he repsonded back saying it's universal and meant for anything with an Inductive, not capacitive ignition system........

They work...

Every one I know that turbo'ed or put a blower on a internally stock 350 blew an engine except for my wife........

This would be perfect that blown Vmax, Nitrous, or high compression bike that you would like to run more advance in without Detting

They will INDIVIDUALLY retard only the cylinder that is knocking, and only to the degree needed to stop the knocking.....

Hope this might help some of y'all........
