I haven't heard of it myself but I can't actually verify whether this would have been present on any of my engine configurations because I've only had a lightened flywheel since being charged and at this point and every new (more powerful) conversion after that has been bespoke mapped.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone  |

Lots of places can chip the gti6 ecu Its the old stlye way of doing it though, the ecu needs opening up and a new chip fitting. They can alter this chip to take into account for mods before fitting, but then if its not spot on the downside is the chip needs to be removed again and put back in the writer to be altered  Pretty sure its only chip wizards that offers to fit a cable to the ecu which they can then adjust the chip without having to remove it from the ecu  ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Great thanks guys, very useful information I would rather go see chip wizards, unless rich w can send me one much the same, which may be a cheaper easier way ? Ill PM him. On a side note, i unplugged the PTS plug and the revs stayed the same for say ten seconds, then they started to go lower and lower till it just cuts out, ECU reset too ?? I thought the TPS being unplugged wont make any difference at all and should work almost as good before unplugging it ?? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Pretty sure Rich uses chip wizards converted ECU's.So prob better off going straight to them,but going by what people on here say it is hard to get in contact with him  ________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Mine has the same symptons also but im not convinced its flywheel unless the pickup is machined in the wrong position. It runs fine on idle, just slight misfire at light throttle and over - run. Think its time to measure manifold vacuum down the road, maybe blank off the manifold vacuum take-off. Failing that its a case of checking wiring and swapping bits with miss ladybell  |

It's usually either the lambda (disengages at high rpms/high loads), or wear at the start of the throttle pot (which is where they spend most of their time).Flywheel shouldn't make it miss, there's plenty of acceleration enrichment, and it would be a lot worse just blipping the throttle and low rpms/high throttle opening than when actually accelerating the car Also, check the coilpacks for any pinholes in the insulation. ________________________________________ - Bespoke rollcages/additions/adjustments.

Someone that had there car remapped said the injector timing needed adjusting due to the lightened flywheel, this cured there low down misfire.________________________________________ Red GTB1756 powered Fabia VRS daily driver,LBSC Gti6 eater........Mac1 ZR R1 kit car build in progress. |

Well after all the issues with mine all what was wrong was the wrong plugs fittted, ie map and tps on the wrong sensor.However mine does not have any misfire at all and mine has the lightened flywheel so maybe its something else as many others hasnt had any misfires when fitting one ?? ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

Not yet im struggling for time but i will get to the bottom of it. Even if it means going as far as testing all the wires resistance from sensors to ecu. Does anyone have a decat with this problem? |

All my work passed its mot no problem or advisers etc but today it just couldnt get an mot due to being a 92 car which is a shame, so waiting till Monday now when ill know if car came with a cat or not when new. Cars passed other years without a cat so will see how it goes. Fook me she is fast though, revs just fly up so quick to what i remember with the old mi it had previously. ________________________________________ Pug fee`ver,Pick a Bogey, buy a Pug.

I have the same problem in about 6th gear 2k rpm 40mph and only slight throttle it misses a bit then picks up also noticed i get a bit of pinking when hard accelerating right uo theought the revs im wondering if its an over fueling problem as some days its ok others its worse, could it possibly be a knock sensor? I only think this as my sensor wiring has been taped up and feels quite flimsy but bot had a minute to get a look at it. |

I dont think you have an issue chap i think your just over gearing not enough engine speed to high a gear does it do the same in 5th at that speed ________________________________________ BLACK RALLYE - phoenixWHITE RALLYE - valliant http://public.servicebox.peugeot.com/ https://www.gov.uk/check-mot-history |

A healthy engine will pull away from 20mph with part throttle with no misfiring or issues let alone 40mph. ________________________________________ 61k miles Ph.1 Diablo '6 Project Thread |
