i took the uim to polish it when i re-connected it, i am not sure if i did it right. i run a pfc. my question is how many of the connectors need to be connected on the uim for a single turbo. i think i connected all the connectors and the car idles really funny and cuts off. never had a problem before the pre-bling. thanks in advance. kvn

For a single turbo FD, you would need very few vacuum lines run.



1 for the map sensor

1 for the BOV

1 for the fuel pressure regulator

1 for the wastegate

1 for your aftermarket boost gauge(if you have one)

1 for your boost controller(if you have one)



I miss anything guys?

Thats all I can think of.

jspec, thanks. i was wondering about the electrical connectors not the vacum lines. i know one of the is on the under side of the uim. does anyone of them stay disconnected when you are single. Kvn

you should plug em all in

jspecracer7

they all get plugged in except for the ones that were connected to the solenoid rack at the bottom. The one that's connected to the UIM(on the bottom) has a piece of blue electrical tape around it. It's for the air intake temp.

those extra plugs...can you just cut them off? or will you get errors or somthing. this is with pfc by the way.

jspecracer7

FOR THE PFC, you can cut off the plugs. BUT if you do that, there's no going back to a stock type ECU. I would suggest cutting the ends off and then putting heat shrink on each individual wire so they do not cause a short.

rx7raca

so theres nothing you could put on the ends of the wires to trick the stock ecu to thinking that they are still there? Lets say, you cut off the plugs and tape them up and have them so they dont touch eachother, it would be like they were never cut...right?



im just thinking this would be better because those plugs are pretty chunky, whereas just have small wires taped up or capped or somtihng. this would be much cleaner IMO.

you will need to KEEP the following plugs



4 x Injectors

fuel rail temp sensor (optional you can remove it if you like, aftermarket fuel rails will not have this sensor)

both water temp sensor connectors on the back of the Water pump housing

Intake mani air temp sensor

Idle control valve

TPS sensor

OMP conector

Knock sensor

crank angle sensor

crank TDC sensor

O2 sensor

Primary boost control solinoid conector if you want to use the boost kit



all others can be removed
