retard timing

[MAZDAJIT]

how do you retard the timing on a protege 5 thru the distributer or the computer

Without reprogramming the computer, using an aftermarket ECU (piggy back or standalone), or modifying the crank/cam pickup hardware, you won't be able to.

The P5 doesn't use a distributor.

Why do you want to retard the timing?

Just so you know what happens when people run nitrous most of the time:

not saying you aren't or won't be prepared but the above is normally the outcome.

you might talk to steve at NSN Motorsports about a J&S Safeguard. It seems to be a great piece of hardware. let me find his screen name and all that.

Edit: screen name is TurfBurn. he might be able to recommend something.

yeah I wouldn't do anything crazy like that without a J&S safeguard.. no doubt.

 

[MAZDAJIT]

whut does the J&S safeguard do

It dynamically retards timing on individual cylinders using a sophisticated knock detection system. It's the best out there
