Hii everyone

first of all i would like to thank everyone over here for sharing their knowledge and eagerness to learn more about making out cars better driven .

so i have APR ECMS that i'm trying to tweak with UNIsettings , it got me thinking:

1- is it possible to reflash it Via OBD or even tweak APR map wishout dissembling the ECU BOX & use the APR programmer port

2-can i use different ECU MAP provider with the same mentioned chip or should i re solder the EPPROM again?

my ECU info:

Audi TT EURO MY2002 1.8T 225HP Quattro 8N0906018AH S0004

APR EMCS : Audi_TT_EURO_MY2002_1.8T_225HP_Quattro_8N0906018AH _S0004_Stages_1,2_V1.1

sadly i dont have the original map file but i got both APR map file and License

ur input is highly appreciated

P.S: i'm starting my babe steps in ECU Remap , looking foward to improve my knowledge

1 - No
2 - yes, if you desolder ECMS-module and solder back original flash chip AM29F800BB
