TDCi upgrades?

For the boost guage just tap into the manifold pressure pipe, will giv u a true reading there. Straight fwd really.

for the manual boost valve you have to tap into the pipe attached to the actuator i think.... but be careful as you could blow the engine, the limp home mode will kick in first or it will just cut out at too much boost to save the engine from poppin!!

Hey fella where abouts is this pipe (the boost gauge one)?

[poormansporsche]

My mechanic has already threatened to break my arms if i touch the valve once hes fitted it ! Hes going to set it to a safe level apparently !

Quite intrested to see how far you can raise the boost before the ecu spits its dummy out i know the rs boys put a different map sensor in! would that just fool the ecu? i reckon i could run a bit more as i get a bit of chuff on full throttle

well had my boost gauge and valve jobbie fitted today, 50 quid the mechanic charged. didnt get time to fart about with the valve so just turned off at the mo. i dont know how you read these boost gauges as its showing 18psi under full boost !! its a bit lumpy over 2.5 k under hard accellaration as well

i dont know how you read these boost gauges as its showing 18psi under full boost !!

That's only 1.3 bar

the pipe is the one that comes out of the inlet manifold, its the angled one that sits under the egr valve. Not the pipe that comes out of the egr valve tho! its underneath and it goes to a black box attached to the bulkhead.

failing that just tap into the inlet manifold.

well i know bugger all about turbo's (engines as well really) but what i do know is that my ole passat 1.8T (petrol) was running 8 psi before remap and 10 psi after apparently so 18 psi seemed alot to me !! ??

[MR_RS]

18psi is a lot for a engine, rs turbos and subarus run around 6psi

Cheers mate


Anyone got pictures of their boost gauge fitted in the dash?

[poormansporsche]

well farted about with the valve and it did give a noticable power boost over 2.5k but it was soo erratic and jerky that i turned it back off - dunno whether its the actuator going mental, the injectors being maxed or the valve itself !!

[mattvik30]

Have you got any pics of where you mounted the gauge?, as im still not sure where im going to mount mine yet.

[poormansporsche]

i could do but i wont embaress myself as at the moment its just selotaped to my parrot display til i work out what im going to do with it

[nedges]

Ha haha,at least your honest.
Watching with much interest what you guys are doing.
Keep up the good work and give us a laugh post the pic of the part on the parrot stuck with the tape
Look forward to seeing the dails and light when there done.

Boost gauge is a good idea for a bit of fun (no idea what the Connect runs at as standard though) but the big thing to check - especially on 'pioneering' mods - is the Exhaust Gas Temps, as that's what will kill your engine stone dead quicker than anything else.......

To be honest (in my limited opinion), dicking about with manual boost controllers is pointless on an ECU fed motor - as the increase in boost needs extra fuel to be of any use - and that can only be done by electrickery.

I'd leave all power increases solely in the hands of the magicians with their laptops - but making sure exhaust/induction mods (removing particulate filter, fitting panel filter, changing to FMIC) had been done first.....

Just as an aside, seeing as I'm a new boy, what sort of map is the 90PS motor capable of - both in terms of power and MPG?
