Help me identify these bits in the pics please :)

[ashy_gtt]

Right as the 172 engine is in my R5 some of the connections arent there so i was wondering if you could help me identify if i need them or not..??

The first one is the thin black plastic pipe that comes from below the plenum (under the map sensor) you can see it in first pic, it has the yellow band around it.

The second one is the one below the throttle body, i guess it just feeds into the air box normally?

the third one to the rear of the throttle body, i have just run this to my brake servo. is that right??

the fourth one is a black plug (solenoid valve) on the rear of the plenum,i was just gona leave it un-plugged and remove the piple off the bottom of it??

Cheers in advance peeps

1) carbon canister
2) Crankcase breather pipe
3) Correct
4) ISCV

nice one, right where should i connect 1 to, or can i just block it up?
are you sure 2 is a crank case breather pipe? its part of the throttle body?
how does the idle stabilisation valve work normally, is it on or off or does the voltage to it control the vlave omre acurately??

Cheers ashy.

if you have no carbon canister, dont bother, just plug it.
Its the vent from back/top of the head where the oil vapour breather seperator is.
ISCV is PWM.

 

[ashy_gtt]

ISCV is PWM.

ahh right dont think my ecu will control that

so i can just pipe the crank case breather back into the air intake?

 

[BenR]

DTA should be able to control it.

Call them.

 

[ashy_gtt]

it seems you are right....

Temperature dependant Idle speed control via PWM valve (shared second bank of injectors)

Ill call them and see how to set it up

Nice one cheers.

On the DTA ecu is there a control for the VVT plunger ?

 

[BenR]

there will be on all decent ECU's as its only a lowside drop switch.

A 172 engine in a Renault 5?!? Thats brilliant!!!

On the DTA ecu is there a control for the VVT plunger ?

ive not got mine wired up as ive only just got it running but there is an aux out for a solenoid valve or relay, however i dont know if that would be ok to run the plunger from?

what RPM would it normaly be operated at?

 

[BenR]

It should be fine to use as the switch.

And the rpm you switch at will depend on the method used to activate the switch.
