I meant regarding the fooling of the temp sensor, sorry, here is the post but u can try higher values than those:



there are a few tricks to fool the ecu into some good timing advance and a bit more fuel as well.
IIRC find the engine temp sensor that has 4 wires into it, this one feeds temp input into 2 ecus, the ignition and injection. usually it should have 2 grounds and 2 live wires. the one that feed the injection should terminate at pin 21 in the ecu just do a connectivity test. once located cut it and fit a variable resistor. now the second one terminates in one of the wires going to the ignition ecu located on the left fender. also cut this and reconnect with a variable resistor.

Good values to start with should be abt:

450 ohms for the injection
and 750 ohms for the timing
and then adjust as u like.
let us know how it goes, it should give u a good power increase.
to see the diff just wire 2 switches the would bypass the variable resistors (short them no need to cut the connection to the resistors since electricity takes the shortest least resistant route)
