throttle body ports

[GRace]

My tb vac ports are blocked off right now. Out of the a1, a2, e, and p ports, which one is connected after the throttle plate? I'm trying to find a place to connect my map sensor and if one of those ports connects straight to the manifold it should work just as well as tapping somewhere else.

If that doesn't work then I will hook my boost gauge to the tb and use the T from the fpr line as map line.

The vacume ports on the tb is all emmissions stuff and egr. You can t you fpr and map together but its always better to have its own. Im going to t that and t my bov and boost gauge.

I always used port E to hook boost gauge up

Does it read vacuum at idle? From what I have read, the P port only works when the throttle plate is open.

(Edit, Nope, E does not read vacuum at idle)

I tee'd my boost gauge off the fpr vac line. I'm using an adapter on the mdp sensor to convert it to a map sensor. (Using ECMlink of course)

As I said above you can t the fpr and your map to the manifold. Then for your boost gauge t the bov line.

I wouldn't T the bov line. I'm leaning towards just connecting the MAP sensor to my T in the FPR but If there is a port on the throttle body that taps directly to the inside of the IM then I wouldn't need to T my map sensor.

Which port on the throttle body would be good for a boost gauge? I dont want to tap into the fpr because im running my map through there.

Does the "P" port read boost and vacume?

I ran mine to the fpr, never ran it anywhere else.

If you don't have any other options, T'ing the FPR line works for a boost gauge. Seen it a million times.

Much better idea than T'ing the BOV line.

I already have my fpr t with my map. So which tb port would read vac and boost, P? Would it be better to run the boost gauge to the tb or the bov to tb? And which port?

I have my boost gauge hooked up to the E port on the throttle body and it only reads boost, no vacuum. I have a feeling the A port will read both. I will figure it out tomorrow and post which, if any ports read vacuum and boost at idle.

I ended up hooking my map sensor to the T in the fpr line where my boost gauge used to be. It seems to work fine.

 

[jpmxrider489]

Did you figure out which port on the tb reads both vacume and boost?

 

[SexyDSM95]

The "P" port on my TB is where my boost gauge is ran to and reads vac/boost.

Ok thanks alot. Thats what I did but just wanted to make sure.
