FIC 1050 latency values?
Are there published (from the injector manufacturer) values for FIC 1050 injectors?
Also, what latency values have people successfully used with FIC 1050 injectors?

This is for FIC 1000cc/min injectors. I wanted to drive the car around and start it in sub freezing weather before posting up my values. Car starts up and idles fine in all weather conditions. This is for a DSM but the code is exactly the same on the evo and the values will transfer over. I do not use a stock O2 sensor though, my ecu talks to my LC1's wideband signal for closed loop cruising. So if anything my trims should be more accurate/consistent than a stock narrow band sensor.

For the global you have to do some math. My base fuel pressure is 56psi. Higher fuel pressure is not a linear relationship with respect to flow. Thus 56/43=1.3. Then you take the sqrt(1.3)=1.140 and multiply this by my rated flow of my 1000cc/min at 43psi to get 1140cc/min. I set my global to 1150cc/min. So for an evo at 43psi base you would take your stock global injector size and multiply it by x when [new inj size/number in ecuflash]=x. If you have higher than stock base fuel pressure you must do the math above.
In the end it is fairly plug and play with a little math and those latency numbers. Like I said my **** starts up and idles in 20 degree F weather with very large cams and large valves. It can sit and idle for half an hour on end, cruises well, and returns 30+ MPG. For the most part, it drives better than stock.
I know of someone running 1600cc/min injectors on the stock ecu but don't know their values, sorry. I just know its easily done
