where is the best place to attach pipe for map sensor in pred ecu to read boost on standard vts intake???

I'd attach it to any take off from the inlet.
I'd look to take it off from just behind the oem map sensor, this is where the charcoal cannister connects to the inlet.
Either that, or 'T' into the FPR vacuum pipe.
On the c2 inlet I've 'T'd mine into the fpr vacuum line - seems to work fine. Finally got it all mapped up today and does go very well !! Plus the induction note from the C2 inlet is awesome but subtle :)

sweet, i was thinking, on the vts intake just after the throttle there is a little nipple, usually having a breather attached to the alloy covers, with the jp4 covers this is not used, could that be used as a take off?????

yeh could use that for a take-off, presume you've got jp4 covers so that nipple is unused ?

yes jp4 covers, so can try that, still gotta get ecu to andy for the sensor 2 .
also does the charcoal cannister need to be connected to engine, wat would happen if it wasnt????

I'm not sure how the carbon cannister works tbh, can imagine the cahrcol inside it just absorbs and vapours and then the excess is just sucked into the inlet and burnt off. I've just got the pipe that connects to the inlet just sitting at the front of the engine bay below the front grill.
I've not noticed any problems so far

just think the pipe looks outa place since everything else has gone, might just run it another way out of sight lol

yeh, just run it so it vents out into some sort of airflow and can't collect anywhere like under the wing, should be fine.

Have to say I'm pretty impressed with the onboard MAP sensor - has made going from TB's to an inlet setup pretty easy.

Can't wait to go boosted either - should be superb !

so not connected to the charcoal cannister anymore??????

No, I've got wiring going to the purge valve, but just got the pipe running free upfront under my grill.

fair enough, i extended the wires that go to it, so there connected, will now sort out a place for pipe, run boost sensor pipe back into car for ecu, then d day woop

use the outlet on the inlet that would normally go to the charcoal canister, this is a nice sized outlet that is ideal for manifold pressure sensors. i would not recomend teeing into any other vacuum sources from the inlet as sometimes pressure fluctuations can occur (particularly cheap boost gauges, dump valves etc)
the charcoal cannister can be discarded.
if possible try and keep your MAP sensor vac pipe around 5mm ID. its important it gets a good strong signal from the intake for accurate readings.

basically everything that this guy said adz. thats where i've taken mine from. if you want a look, give me a text and pop out one night

cheers m8, will defo take a look when im out that way, expect a text bud

I'm Tee'd into the FPR regulator which run's my gauge & MAP sensor to the Predator, not had any issue's to speak of, would highly recommend 4mm Nylon tubing over silicon vac hose thou, the nylon versions off ebay are flexible and does bend really well without kinking unlike silicon vac hose.
Hope that helps..
