ISC Elimination?

[mk3 bamf]

Can I bypass the ISC water lines with no ill-effects? Or can I just eliminate it all together.

you can elim the water lines. its mostly to keep it from freezing when you live/drive in a very cold climate.

the water lines also feed over to the tps. it just makes a big loop out of the block, isc/tps, back into block. all we do is just make a loop on the block from where it comes out to where it goes back in.

why do people eliminate the coolant lines to it? curious. im not gonna do it regardless though i live in a cold climate =D

dont know if you care... but its easy to free up a good amount of space by getting rid of the heater valve... i did it because im getting rid of all of the vacuum lines and stuff i just dont want or need.

To keep the intake cooler, which could equal more power.

Plus its one less hose you have to worry about leaking and makes things simpler.

Because they ultimately either get rid of the electronic, or do away with it as it's plumbed in tandum with the TB as mentioned above. The purpose there is if an aftermarket TB will be used, or they no longer want hot coolant heating up the intake air.

what do have to do to get ride of the ISC?

 

[tlo86]

makes sense! for some climates.. heh

Its for high humidity conditions, not cold temperatures. At the ISC, there is a sudden pressure change (ambient to vac) and the temperature of the air will drop (basic physics) causing the water vapor in the air to freeze out and plug the valve.

^^^ with OAT of +10 deg C the most likely point at which it will happen

 

[mk3 bamf]

Would it be ok to put a little filter on it insted of the hose going to the air intake?

 

[jdub]

Not with a stock set-up (i.e. AFM and ECU)...with speed density (stand alone or MAFT Pro), yes.

 

[rumptis]

MAP ECU 1&2 will eliminate the AFM as well.

what kinda temperatures are we talkin, lowest it ever gets here is 25deg farenheit and its covered parking during winter.

Well. I'd just leave it stock. I'm better off doing this as i only drive my car in the summertime, and garage it in the winter.
