Hello,

Looking for some help/ a baseline map to work of for my engine. It's a 3.5 rover v8 running a Dennis priddle sprintex 102 supercharger making 9psi of boost. Running through a Holley 4bbl carb

What I'm looking for is some quidence on setting up megajolt to run this, If possible does anyone have a rover v8 map for a supercharged setup?

Any help would be greatly appreciated!

Thanks Dominic

To be honest, I would just book a couple of hours on a rolling road and set it up specifically for your motor.

In base, just use a 3.5 fuel and ignition map for setting. Guess they are available for the NA 3.5 Rover V8.

Ignition wise start at 10' at idle. advance curve starting at 1200rpm, 38' total at 4000rpm and then flat out. ( that's 38' minus 10' idle means 28 total advance)
Boost wise, cut out 1' advance / psi boost so you end up with 38 minus 9psi equals 29' advance total at 4000rpm and higher.
Guess you're running a MAP sensor so this must be easy to set.

Fuel 14 afr at cruise. Start at 12 afr at WOT.

This is the setting from my 3.5 supercharged, carburetted, MSD Distributor ignition engine.
