he would be nowhere near 14psi, if he had no fcd.... and *** for ecu, he says he has 2 extra injectors, so he either has a piggiback/fuel computer, or stand alone, or he has them wired with a switch....

- los injectores estan siendo controlados por la ecu stock, y se encuentran conectados en serie
- la bomba de bencina es la del rx7 fd
- tengo un fuel cut defenser knigth sport (fcd) trabajando correctamente, hasta hace 30 dias atras.

todo trabajaba bien hasta hace un tiempo, los injectores funcionaban correctamente y la relacion aire bencina era excelente, con 14psi, pero ahora comenzo con el problema del ralenti, las detonaciones sobre los 5.500rpm....

ok.. more information:

- injector are controled whit ecu stock, and its be conected in serie
- fuel pump is of a rx7 fd
- i have a fuel cut defenser

all things work correctly, but now appair the problem whit ralenti, and detonation over 5.500rpm. air/fuel were great at 14psi but maybe now is bad becouse some injector is dead or ecu dosent work good im try whit n318 ecu and n340 and dosent happen the problem continue...

puede ser el ecu, pero que tippo de gasolina estas usando????? noce como se mide el octan aya, pero 14 psi en un to4e is alot for pretty much stock system... que intercooler estas usando??? y cuanto degree te timing usas???? trata de retardar el tiempo un poco, y si no funsiona trata de bajar la pression un poco tambieen, a ver si pasa lo mismo....
