alync406 4 Posted April 28, 2008 I have fitted a gti6 inlet manifold to my 1.8 406 and it just does'nt run right.If you open the throttle fully it just misfires.If you open the throttle slowly it seems ok.Has anyone fitted one of these before.Would it be that its not getting enough fuel- would it have to be remapped(can it be remapped-it has a sagem ECU).Thanks.

welshpug 1,661 Posted April 28, 2008 Which throttle position sensor are you using? the gti6 one may not be compatible directly and require the pins in the plug swapping around. Share this post Link to post Share on other sites
whizzer71 0 Posted April 28, 2008 Also check the pin positions on the map sensor,they are different between early and late Gti6's,dont know if they may be different on the 406 also ? Share this post Link to post Share on other sites
Miles 331 1 Cars Posted April 28, 2008 Which injectors did you use too?, All the XU7 stuff needs swapping over really and a Remap is a must Share this post Link to post Share on other sites
alync406 4 Posted April 28, 2008 Which injectors did you use too?, All the XU7 stuff needs swapping over really and a Remap is a must I used the 406 throttle position sensor and map sensor.I used the gti injectors-they are the same resistance as the 406 ones and where they go into the manifold they are a bit longer.Thanks for the replies. Do you know if the sagem ECU can be remapped? Share this post Link to post Share on other sites
alync406 4 Posted April 29, 2008 I put back in the xu7 injectors and it runs much better. Thanks for the help Share this post Link to post Share on other sites
