jam racing ecu or chip

[GT-TUNING]

Is it possible to get just a jam racing chip or do you only get a complete ecu? what difference do these make??

dont think u can get the chip mate, a complete ECU is difficult too find but they pop u here and there in time

It is covered many times before what they do, but an idication is

eliminate fuel cut and speed cut
advanced timing
and alters fueling
