Revo Problem

[jonesya3]

I bought a revo's stage 2 ecu off ibiza-cupra on here and its been running great until i used the sps2 i bought off ebay for the anti theft, Now it runs like a bag of crap its lost all the kick you get between 2 and 3000rpm in any gear and even when the turbo kicks in you can tell its not a happy bunnie

But even when the car was running better it would only boost to 16/17 psi and hold at about 14/15 so im wondering if i possibly have a leak somewhere as well, so i need abit of help from the more experianced on here any advice is much appreciated

did you stick it in stock mode by accident?

not being funny.. but if you dont have the downpipe or the fmic fitted, you shouldnt be running stage 2

 

[jonesya3]

Thats the first thing i tried but it still boosts to 15 psi just not very well

Yer im just waiting to get my blueflame downpipe and sports cat but i did check the revo site before i bought it and it does say downpipe and race cat optional but i understand they make a big difference on a stage 2

them figures you gave for your psi, sound ok to me for your spec, as acid said though, you need dp and FMIC ASAP, shouldnt be running stage 2 imo, i peak at 18psi and hold @16psi until about 5.5/6k

got vagcom? start loggin the essentials if you can, it narrows the problems down

it could be boost leak...check all vac hoses are connect and not split, check dv is all connect properly and doesnt sound whooshy

unplug maf and see if it runs better or worse

just the first of alot of things to check

The dump valve is VERY whooshy and does sound as if its dumping as well

but i have no idea what it is niether did timd or ibiza-cupra they thought it might be an old baileys or something but thats getting changed to forge as well

Its probably does on some cars mate just not mine lol

 

[David_smith_909]

what DV do you actually have? its not a atmospheric one is it?

by the sounds of it it is, not a good idea, as you have said, you need a recirc asap

u sure its not "up to" 20psi???? depends on how aggressive the map is, but a stage 1 map is a generic map and i think you will have to be pretty lucky to be hitting 20psi, i woulnt read too much into the "marketing" side of things, suck it and see

It looks like a recirculating valve with 2 main pipes one at the bottom and one at the side with a small vacume hose out of the top but i have no idea what make it is as it came with the car

sounds like a recirc valve (which is good)

Fair play. Well mine is only peaking at just over 15psi so it's not hitting 20!!!! Have no idea wot map it is tho!!! I have just fitted a boost gauge and realised it's not standard!!!!

ill check all the hoses later but i think the dump valve is knackered anyways but it still does make any sence to why the car would go from working fine to running like crap after using the sps ? and i have tried the different fuel settings

Sounds like a absolute map

do you get wastegate chatter? if you take off your DV and push the piston up does it drop back down? a few things you could be checking, DV, VAC hoses,

do you get any lights on the dash?

i have no lights on the dash or wastegate chatter but ill try all the things you and acid have said later and let you no how i get on fingers crossed

 

[acidstrato]

looking at your mods are you running a standard bosch valve? black and made of plastic?
here lay your first problem!

i hit 21psi on spike no problem on stage 1

Some1 else has said that.

I don't think i would see any improvement upgrading to revo ST1 tho!!

Could i ugdrade to St2 without having st1?? I know i need the other bits!!!

stage 2 is only 50quid if you have stage 1 but if you just go to stage 2 its like 500quid
