My car is a 2000 bugeye and is going for a ecutek remap next week I have a full decat 3" exhaust , upgraded fuel pump, forge dump valve recirculating type, green panel filter, upgraded fuel regulator, problem is it has a slight hesitation when I go above 5000 revs and injectors are sometimes opening 105% when they should be opening around 90% all sensors working, no leaks at turbo or dump valve, will the remap cure this and what sort of gain can I expect car is 215 bhp standard

 

what have you get the fuel pressure set to?

Simon

 

not sure what pressure is set at, it was the mapper who set it, but i had the injector problem before the regulator was fitted.

 

so it has been mapped already?

sounds like pressure too low or pump problem or fuel filter probelm

Simon

 

hold on a minute.. all of those wouldn't make injector duty increase..

so it has to be maf or the air flowing threw the maf at fault

dump valve openning.. try refitting original to eliminate

 

no it has not been mapped yet

 

problem with injectors was there before new dump valve fitted, had same problem last year ecutek diagnostic on laptop came up saying maf faulty replaced the maf and this solved problem, same problem has re occurred but this time maf is working ok

 

air leak causing maf to over read

dump valve perhaps openning on boost.. try the original..
