Delfin Posted July 6, 2007 Share Posted July 6, 2007 Heya, gah, just fixed my oil leak problem, now it's time for the next one . When I picked the car up the other day I drove slowly home from the garage as it was raining, never got above 2-3k rpm. The day after, I took her our for a lil test drive, and noticed that when the second turbo jumps in the revs start going up and down, the car twitches and doesn't want to pull like it should. I got a lil worried, and tried about 4-5 times. The last time I covered my BC with my hand to see the numbers, and I noticed I was doing about 1.2-1.3 bar, instead of 0.9 which it's set to do. Now I've had it in for headlight change and fixing of the oil leak, which was a lil thingy in the gearbox which measures the speed (hence my speedo dying). I dunno how sensitive the BCs are if you disconnect any wires and such... I also don't want to fiddle with it myself before I know how it works, Paul specifically warned me about that when I bought it . I've sent Paul a PM but he doesn't answer, so I'll give you lot a try too Edit: Forgot to add, it's an old version of Apexis AVC-R, I'll take a pic and upload asap.

wez_p Posted July 7, 2007 Share Posted July 7, 2007 have you got any cats fitted? is there a restrictor ring in your exhaust? is yours a j-spec or UK? without any cats & no restrictor ring you will be possibly boosting to a higher level & the boost controller cannot bring this down - it can only raise boost from what i believe is the wastegate controlling it. is it the same if the boost controller is switched off? this would be likely to highlight whether it's happening regardless of the boost controller Link to comment Share on other sites More sharing options...
edge Posted July 7, 2007 Share Posted July 7, 2007 Did paul fit decats to your car? If he did then he would of put a restrictor ring also. Maybe the boost controller needs reseting if they disconnected the battery? What one is it? maybe someone has the same and help with the setup.

Delfin Posted July 7, 2007 Author Share Posted July 7, 2007 The car is a j-spec manual TT, no decats, only mods is a Blitz BOV. K&N airfilter and the BC, and old Apexi AVC-R BC (I'll get photos up within 30 mins) I didn't try to switch it off yet, I was told not to touch it if I don't know what I'm doing, so I didn't... Thou if the car hasn't got any decats, and the BC can't bring boost down, just up, if I switch it off wouldn't it logically bring the car back to its original boost? Or does it do the opposite, bring it to maximum? Paul told me never to drive the car if the BC didn't power up when I started the engine. Link to comment Share on other sites More sharing options...
