boost is hardcoded in tables on ECU so I dought it will work unless you change codes and increase the +- deviation tables for limp mode.
BTW....Makes no sense

but it can be really useful for controlling boost spikes and generally normalizing boost pressure,,, but I'm thinking of a boost valve and don't know if it's the same thing as a boost controller,,,
I really can't see you controlling boost spikes that way. Especially since spikes are 2-3 second events (usually).

i was thinkin if it is possible to increase acceleration and top speed using boost controler and without and modifications to ECU?
On a diesel a fuel controller would be more appropriate...
The tuning boxs and evry mods basically do this (but without a knob in dash). It basically fools the ECU into injecting more fuel.

so you want this mod to give you more power?
problem is that blowing more air isn't enough, you need to raise the fuel delivery too [unless you're running too rich and adding air can help burn the unburnt fuel but it's not the case if the ecu is stock].
As I see it, boost valves are used to normalize boost delivery, not [usually] for raising boost pressure or to give you extra power.

so basicly fuel controler is better......and can u plz explain "limp mode" i've heard of it and still haven't figoured it out cos i am still new to this kind of engines
I'd say do a remap and get the best out of the engine compared to raising only fuel or boost.
limp mode is the protection mode in which the ecu goes if it detects a harmful variation in the boost pressure. i.e., the VNT blades get stuck and the boost pressure goes too high putting the engine at risk,,, the ecu sees this and cuts all the boost to enter a safe operating mode,,,

I'd say VNT-17, 1.8T intercooler, bosio nozzles and then custo remap,,, [and a clutch too] then the car could be quite performing,,,
is this time and pressure dependant ? what is normal for a 130? I have 30psi spikes and no limp mode, (not bragin'- complainin' ) currently trying to make a boost valve but can't get a good seatprc said:
Nic, on the boostvalve site there's one for the 2.0 liter, maybe you can mail them asking if it's ok to use that on the 1.9 130 comparing boost pressures,,, [both engines use a VNT-17 btw]
:birdy: 
If you mean end as in blow it up stage 1 should be safe enough after that i promise i will try my best mate.basstard said:
when you gonna end that audi btw mickey?
