Having problems with cold start after install of rdx injectors

Post by Rsxtuner08 »

I installed rdx injectors and ever since I have to crank on my car forever for it too start, I had my tuner change the dead times and adjust the kal for the new injectors, the car feels great after it is started.. The funny thing is, if it is colder then 31" outside the car will start fine wether it's a
Cold start or been just sitting there for 15 mins. I was thinking of change the 42" injector pulse close to that of the 31 to see if that would help, would there be a problem with his or do any harm to the car. I have even reduced cranking fuel to -15% because I have to press the gas pedal down for the car to start if it's over 32" outside

You will just have to try and see if that helps.
