Let's get some in depth discussion on how all this stuff relates...I got a couple issues with DIY ITB settup and having a little trouble getting things straight.

I am running a Power FC and tuning myself but can't seem to get any good advise on tuning with it from others that are knowledgable on here.(I KNOW THERE ARE SOME)

-What do TPS sensors tell the ECU?
-What do MAP sensors tell the ECU?
-What range should vacuum be at normal idle with ITB's?
-What inputs(sensor readings) determine fuel addition?

**Lets share the knowledge here people and not just use this board as a gossip corner.....

 

ANYONE.....?

 

i posted a reply to your post in tech.

The TPS uses different voltage levels to offer the ECU an exact position of the throttle plate. The MAP sensor uses different voltage levels to offer the ECU an exact measure of vacuum present inside the manifold at any given point.
