Need help

Im completely new to tuning and nistune and i made a big mistake. basically i pressed the sync button without having any fuel or timing maps loaded thinking it would sync the stock map from the ecu to my laptop but instead it appears to have done the opposite and now i have no tune on my ecu? Is there any master reset to put the ecu back to stock???

I think you can download the ROM pack, and load the *.bin file that has the same number as your ECU to your ECU...

thats correct. i've fixed that for the next build... shouldnt let you do that next time

find your ECU part number, install and locate in the ROM pack and upload the maps back to the ecu

What about resetting the k value? I have a stock s14 sr20 stock maf and injectors where should the k value be? I'm going to read a nice long write up on using nistune once I get the ecu back to factory lol

When you load the factory ROM image back into your ECU everything will be reset to normal again, including K (injection multiplier)
