Need to know how to install custom tune for SRT4 Neon

[SingingMoFo]

Hello. This is my first post to please be kind. I bought my SRT4 with an i2 set with a custom tune for 1025cc injectors. I just upgraded the injectors to 1200cc and it’s running very badly. Barely starts. How can get and upload a new custom tune with my i2? I have all of the proper cords. Thank you so much.

this is what i do

connect usb cable between laptop and i2, accept disclaimer

it will appear as a new drive, for me its f:

drag and drop the file to the f: drive.. and you'll see on i2 that its loading the file..

all done.. load away

Thank you for the reply. I got that far, but I need to change the tune from 1025cc injectors to 1200cc injectors. I need to modify the current one that I have. Any suggestions on how to do this??

Thank you!

i think you need a rescaled tune, and your tuner will need to use CMR to change injector size
i've been able to modify basic things like boost, timing, rev limit, fan on temp etc..

Yeah, you need to contact a cmr tuners and purchase a new tune for the injectors.
