Screamin Eagle ignition module dyno tuning
Hi, so with this issue of my exhaust, I was wanting to explain that I replaced my slash cut slip ons with monster ovals from Vance and Hines. I am wondering if the module will need to be reworked for the new slip ons? It also has an andrews cam and rejetted.

It is the genuine Harley Davidson Screamin Eagle module with 6 pins on back for adjusting on or off,
I only know its an Andrews cam
no head work that i know of
not sure on ratio
rejetted for larger jets

set switches like this, after setting your base timing. Then leave it alone.
sw-1-off voes normal
sw-2-on ands-3-off, this is ignition curve 2
sw-4-off and sw-5-off, this is your rev limiter. 6k
and sw-6 is OFF, for dual fire coil and ON for single fire coil..
You can also google Dynatek 2000i ignition module instructions to help you. They made the SE modules and the directions are denticle..
By the way up is on and down is off

Curve 1 is very aggressive. It doesn't sound like you have the build to run that or the rev limiter at 6500.

not knowing what head work if any, ( springs, blending, etc ) I would stay shy from anything over 5500 rpm..sure, they all will * turn 6000+ rpm's, but without the correct seat pressures and at height spring pressures( cam matched effectively) you can nearly assure that at some point you will get some valve float, or even bounce off the seats...ad then you start heading towards some serious issues...without the proper cams, compression, and a multitude of other performance factors..turning it over 5500 rpm will give you nothing. it is most likely ( as a guess) an Andrews EV27, and they are decent cams to from around 1800 - 5500 , and even to 6000 but it takes compression ratios at or over 9:25.1 and less than 10:1 to get them to work into that high 5800+6000 area..better safe than sorry till you've been in the motor and know what is there.
