ok so i installed a set of yellow side feed sti injectors off a 05 sti into my 2002 wrx.
-results...... sputtering at 5k rpms and coulding proceed after 5k.

Today my friend brought over his gear to help me remap my ecu...

-what we did..... took stock map and modified the fuel injectors from 420cc to 519.99cc

would the voltage matter if I copied the 05 sti injector scaling and latency to the stock 02 wrx rom? They both are using similar and different voltages.

Copy the latencies from the 05 rom. Modify the voltage range and latency values.

I can modify the voltage headers just fine. Do you have user level turned up to advanced(or w.e the highest level is?)
