hi just wanted some advice

i have e8 mr 340 which has another little silver box connected to the engine ecu , i assume this is a piggyback ecu.

i have read my rom sucessfully with ecuflash 96260007

if i was to change to tephra v5 or v7 would it be advisable to leave the piggyback connected or to remove it

thanks

 

Remove it
Fit a Grimspeed 3-port BCS
Tune the stock ECU with a TephraModv7 96260709 rom.

 

where can I get 96260709 from thanks

 

From Tephra directly, it is a donation item from him only now.
9626 is the best of the Evo8 roms.
