WE TRY TO INSTALL UNICHIP PIGGY BANK ON I AND THE "CHECK ENGINE" LIGHT WAS ON, AND WHEN WE SHIFT THE GEAR TO D, IT SHOWS 4TH GEAR INSTEAD OF 1ST GEAR

We run a check on the dealer but it didn't show any problem. But they guessed it was the ecu. Please advise

Maybe but you need to let the dealer settle this as it is a warranty item with the year. Be carefull what you do with the complicated electronics.

Piggy back chips could have been installed wrongly or does notmatch. Fiddling with the engine management system could mean voiding your warranty.
