Why won't my car start when it gets hot ?
I have a 1987 mustang gt running with a cobra ecu.
I also have 24lb injectors from a navigator. Early
model upper and lower explorer intake. Maf air
calibrated to 19 lb injectors.
It could have a vapor lock.
Whats the fuel pressure? ('93 Cobra? EEC) With the calibration 19lb and 24lb injectors MAF primarily controls dynamic throttle response using factory fuel map pulse width for 24 lb injectors. Wait just tune it right! $250 for tuning hardware from Aftermarket. $110 for the Software to tune it from EECAnalyzer. Roughly $460, and you will also be able to manipulate Fuel Tables, Timing Tables, Disable Emissions, Adjust Decel Fuel ShutOff, Displacement, Tune for best acceleration, etc..Ford did things a little different... Actually, you could call it the "Right Way" Ford Calibrated the stock EEC to read the output of the MAF meter used on that vehicle series. This is done with a setting called the MAF Transfer, which can be thought of as a way to translate MAF voltage output back into an air flow number (CFM or Kg/Hr). There are 2 settings in the EEC for the Injector size, called the Injector High Slope and Injector Low Slope. Basically, this setting tells the EEC how much fuel will flow from the Injector for each millisecond the Injector is open.
