Slow 'n' low 0 Posted July 31, 2010 Easy, Just got my G60 back after having a new ECU, chip and pulley installed, but it seems to be miss firing at high revs when flat out. I know it's not an ignition miss fire as not only has it had a new distributor and leads etc, but it doesn't happen any other time than flat out. I'm thinking do I need more fuel going in with the extra boost? As in some red top injectors or to fit a fuel regulator? Any help on this will be appreciated.

Supercharged 2 Posted July 31, 2010 When you say high revs and 'flat out' are you sure it's not the MAP sensor dragging the timing back? Quote Share this post Link to post Share on other sites
Slow 'n' low 0 Posted July 31, 2010 Hi sorry for the late reply people. Firstly thanks for the replies!! It doesn't seem to be rev related at all, only when I floor it. Because of this I can't help to think it's definitely fuel related, maybe some red top injectors or checking the fuel pump would help? I'm going to check the spark plugs are o.k and that I have the right kind of rota arm on it (as I've heard that the round types that are sprung loaded act as rev limiters) just so I can rule the ignition side of things out. Thanks again. Mark Quote Share this post Link to post Share on other sites
