e6k showing 100% duty while cranking?
 
would anyone else have any cluewhy my e6k is showing 100% duty while cranking? what should the duty cycle be during cranking?

That doesnt sound right. At 100% duty cycle, the injectors are firehosing the engine..

100% Duty While Cranking
 
check:

Maps:
battery voltage, post start, and fuel below 1k and vacuum.

Main Setup:
make sure your MAP sensor matches what you have in the software setup

i had a wire near my ecu short and this caused the engine to go so rich it would not run below 2K. (wasnt datalogging so i dont now what duty). check for shorts

try looking at the "engine data page" online before cranking... anything weird?

Duty
 
while the fuel pump is priming the injectors should pulse. this usually blips the duty to ~4-10% depending on primer map.

while cranking the duty is ~6%. it is surely less than 10%

Is your car turbo or NA? where is the arrow on top of the bars at when you crank? the only reasons i can think of right now are a faulty map sensor reading, a correction map out of wack, RPM spiking (to 16000rpm) due to noise in the trigger, making the ECU pulse the injectors all the way.
