New frame up build - MAP sensor question

[Zole2112]

First post, I prefer reading and learning on my own but some things are hard to find or understand for me anyway.

I'm building a chopper frame up and learning as I go, I'm an old guy (62) and I've worked a lot on cars but not a lot on bikes other than some modding of a Honda Shadow that I have and rewiring a Honda Superhawk. My question is around the MAP sensor on the bike I'm building.
I have a stock 2005 Twin Cam 88 that I'm using and I just bought an S&S Super E carb for it. I plan to use an Electronic ignition such as the Programmable Electronic Ignition from Ultima or a Dyna 2000 (I haven't bought that yet). Do I need to still use the MAP sensor with this setup and if so how do I connect it? I believe the MAP sensor would normally connect to the ECM.

There is likely information you need in addition to what I supplied but I'm not sure what else to add at the moment.

I'm not an idiot but I feel a bit idiotic on this as I can't seem to find the answer and I guess I don't know.

Thanks guys!

I had to google MAP sensor because it wasnt making sense. If you running a carb you dont need a map sensor.

Like Spade said, you'll have no need for that sensor.

I'm curious, what frame are you using? Will you have to register it as a special construction ?

Good luck with your build. Try and keep it as simple as possible..

Hey! welcome to the forum! Sorry if this is becoming the department of redundancy department but, a MAP (manifold absolute pressure) sensor is only required for electronic fuel injection. So, no... you don't need it.

Now, correct me if I'm wrong (which I apparently am according to my wife's reiteration) if you're running a twin cam, the Super G carburetor from S&S seems better suited for that application.

I think over 103ci a G is better but under 103ci a E is better (what I can remember lol)

but hell a lot of people are running mikuni's so...I dont know.

Thanks guys, I did pick up a Super E. I appreciate the info!

Yea no MAP sensor with a carb, duh lol I should have known that!

I will have to title it, I have the Certificate of Origin for the frame which was never built and bills of sale for pretty much every part, based on the WI requirements I should be able to get a title.


The frame is a 2005 Santee Extra Wide. Here's a pic of where I'm at....

My wife is pretty much always right, I'll vouch for that lol. I was talking to a buddy of mine and he said the same about the Super E, I'll try it and if we can't get it set up I'll have to pick up a G.

Bike Looks real clean!!

Hey worst case, you will find someone who wants an E and will trade for the G, (Seen it a few times)

Good luck amigo.

Thanks man!!

I think you mean a VOES (variable operating electronic switch). The mother of the first sensor. Switch is for the simple pagers. Sensors are for the indepthers.

VOES is vacuum load that changes the ignition curve.

Dyna is pretty bulletproof.

PLug off the super E if it has access to vacuum for the VOES.


You don't need the VOES. Dyna takes care of plain old electronic ignition. You more need the HD ignition box to move the curve or the Dyna that mimics the HD's electronic box for the VOES.

Excellent, thank you for the info on the VOES, I would never have figured it out. I'll plug the VOES inlet on the carb.
