omer javed Posted September 25, 2016 Report Share Posted September 25, 2016 Hey guys .. we have just hooked up EVO 8 565cc low impedence injectors along with 6 ohms honda resistors (2 due to 6 injectors). and started the car using VIPEC v88 basemap setup for 440cc stock injectors. every thing is smooth but whats odd here is that with the evo injectors , the car is running super rich at idle when we set the base fuel pressure to 39psi. on the similar setting with stock injectors we ran fine. Also before going standalone , the car was on stock ecu and afc neo setup which also required -22% taken out but the fuel pressure needed to 18psi or 20 psi .. the moment we set it to 30+ psi the car was uncontrolable using the afc limits.i have a standalone now.but my tuner says that the injectors are not behaving as they behave in an evo 8.. he is an experienced evo guy. THis is his first supra tune.. Are we missing something ?? i have low impedence injectors wired with resistors which is the way it shud be .. double checked all the wiring and resistences.. I will appreciate response and guidance here ..regards Quote Link to comment Share on other sites More sharing options...
Simon Posted September 26, 2016 Report Share Posted September 26, 2016 Assuming you are running sequential fuel you will have to us one ballast resistor per injector.As the idea of the ballast is to limit the current for the injector. With only one injector on you will be ok but as the duty cycle increases to the injectors you will end up with more than one on at a time and the current will be effected.You need 6 x 4R7 resistors or a ballast off the likes of a Skyline GTR Quote Link to comment Share on other sites More sharing options...
