Jimmyl Neutral Newbie September 4, 2003 Share September 4, 2003 I asked the pros already. I also needed to reset ECU. YES, disconnect the HVS +ve first, then take out the battery -ve to rest ECU. Link to post Share on other sites More sharing options...
Phochem Neutral Newbie September 4, 2003 Share September 4, 2003 Hi, how you guys normally reset your ECU? izzit only by plugging out the -ve? Link to post Share on other sites More sharing options...
Jimmyl Neutral Newbie September 4, 2003 Share September 4, 2003 Normally disconnect the -ve terminal of battery and wait 5 minutes, 20 minutes to be sure. Then connect back. Radio and clock reset also. Link to post Share on other sites More sharing options...

Acemundo Supercharged September 4, 2003 Share September 4, 2003 sorry disconnect from where? all i see on the battery is 2 knobs....is there a wire underneath that links to the battery terminal? Link to post Share on other sites More sharing options...

Yttrium Neutral Newbie September 4, 2003 Share September 4, 2003 (edited) Another method is to locate the fuse for the radio and clock and take it out for a few minutes. You may find this more convenient than disconnecting the battery. Edited September 4, 2003 by Yttrium Link to post Share on other sites More sharing options...
Jimmyl Neutral Newbie September 4, 2003 Share September 4, 2003 One of the knobs is +ve , the other is -ve. Take out whatever cables is connected to the -ve knob. Look on the battery marking, it's there. Link to post Share on other sites More sharing options...
Acemundo Supercharged September 4, 2003 Share September 4, 2003 you show me on sunday leh.. cos all i see are the knobs on the battery......don't see any wires connected to the battery........or maybe i am blind........check my car later. Link to post Share on other sites More sharing options...
Acemundo Supercharged September 4, 2003 Share September 4, 2003 oh, this must be in the fuse box. but do they mark the fuse for respective use? Link to post Share on other sites More sharing options...
Acemundo Supercharged September 4, 2003 Share September 4, 2003 Normally disconnect the -ve terminal of battery and wait 5 minutes, 20 minutes to be sure. Then connect back. Radio and clock reset also. what can we achieve from resetting ecu???? after installing hvs and say magfuel???? Link to post Share on other sites More sharing options...
Phochem Neutral Newbie September 4, 2003 Share September 4, 2003 (edited) normally what i do is remove the -ve from the batt, plug out the "ECU" fuse from its socket. Wait for 2mins. install everything back then start the car w/o radio and A/c and let it idle for 5mins then turn off the engine(pulling out the key) and start engine again. before that i will also warm the engine to ops temp. i "learn" this from a toyota guy many years ago. dunno if this method still applies today? Comments anyone? Edited September 4, 2003 by Phochem Link to post Share on other sites More sharing options...
Yttrium Neutral Newbie September 4, 2003 Share September 4, 2003 Yup usually its marked. Link to post Share on other sites More sharing options...
Phochem Neutral Newbie September 4, 2003 Share September 4, 2003 Hi, have u heard of removing the fuse for ECU? 'cos it might be a dated method of resetting the ECU and am afraid it might result to side effects. Link to post Share on other sites More sharing options...
Mojoe Neutral Newbie September 4, 2003 Share September 4, 2003 I installed HVS without resetting.. so the steps are? Correct me if wrong: 1) Remove +ve of HVS (but leave the +ve of batt and -ve of HVS intact?) 2) Remove -ve of batt and wait 5-10min 3) Connect back -ve of batt 4) Connect back +ve of HVS (assuming HVS -ve still on) 5) Zoom zoom and fly!! hope i don't sound anal Link to post Share on other sites More sharing options...
