Style chooser

I'm using 4G92P fuel injection engine. The Mod i had done on my car that related to ECU only replace my auto gear box to manual G.B without changing to the manual ECU. and also i got a turbo timer that already broken but the wire still connected to the ECU.

my problem is the Mech can't detect my ECU when he use some computer console stuff to detect my ECU and then check my car problem at T.body(tuning after changing new T.Body). but My car seems to be normal as the 'Check Engine' light...
