Heading to the garage now to start the install and my main, unresolved-in-my-brain question is if i need to hook up the vacuum line that is on my current stock distributor, on the 123. |

Bit more info from the maunfacture's tech guy Christian...
Hello, Rick, The standard curve included in a Tune+ is a curve for manifold vacuum. Ported vacuum is also possible, but that requires a different curve. The range of the vaccuum sensor is 0-200 kPa. These are also the maximum settings when programming the curve with the Tune+ app Best regards, Christian van Dijk Albertronic BV Zuidbaan 510 2841MD Moordrecht The Netherlands So, as delivered it's supposed to have a manifold vacuum source. I can see how you could semi re-create for ported as you can input any negative or positive advance value (up or down 20) at any kPa value. I think it would be a BITCH to map out a vacuum advance curve to ported vacuum. I know what I'm doing, and I wouldn't see that as a challenge that needed to be overcome. They have a 2-bar MAP sensor in this so it can handle boost retard up to 15psi which is KICK ASS! With today's tech and fuels, they should have put a 3-bar sensor in it. (the MOST common). Lots of systems run more than 15 lbs. now. Personally, if I was building this, I'd provision a 4-bar sensor for expansion. Both Ed and Christian replied in record time in my book! |
