PC Pro Installed and having issues

[happychap]

My PC Pro arrived this evening so I have installed it and took it for it's first test drive. The car hesitates around 2800 and feels likes it's losing power.

Do I need to cap off the other connector on the vacumn hose? I would start messing with the settings but I'd like some advice first in case there is a different problem

Just took the car for a 2nd drive to watch the lights on the PC-Pro

The green light is on steady under acceleration and the red and green lights flash when I take my foot off the gas

If you're talking about an unused connection on the Y connector, then YES you need to cap it off or you can just replace the Y connector with a straight one if you only need to connect the vacuum hose to the PC-Pro.

You should be able to find one at your local auto parts store.

OK capped off the end and that took care of the issue, thanks Serpico

Now I just need to drive it around for awhile and see if it fixes my issues.

I know every setup is different but I thought I'd post my PC-Pro settings anyway. The fifth injector is only providing a tiny amount of fuel from 3.5-9.5psi.

Green- Zero
Yellow- 3&4
Red-4
Yellow/Blue-8
Red/Blue-8

My A/F ratio is real good and my car is running extremely well.

Uhhhh Tom,,,, got anything else that needs testing????? :)

Thanks again for everything!!!!!!

Glad it is all OK now. If you don't want to use the "Y" connector, you can connect your hose direct to the card. I added the "Y" connector for those with a boost gauge or device for driving a 5th injector. Sorry about that.
