Im confused on what to scale my injectors to. Since the stock injectors are scaled to 513, do I scale my new ones to 788 or go smaller to 780?

 

i would try 788, then adjust the voltage for the injectors to get it correct.

 

it wont let me scale them to 788 it goes to790. After I changed them to 790 I cant go WOT without the car falling on its face. What should I change the voltage on the injectors to. Im new to ecuflash so I dont know how to read the settings.

 

try 513/550 = x/845 and try and work from there. NM I calculated that and it is 788 lol

 

lol yeah thats where i got it from.

 

If you dont have a wideband stop now until you get one. When you have one you need to be logging your fuel trims at idle and cruise. Once they are within 2% (by adjusting the latency) go back and remap your fuel table.

 

2% of what

 

Within 2% of each other. Please review the scaling injector thread for the full detailed method.
