liang Posted February 8, 2017 Report Share Posted February 8, 2017 i using g4+ ecu blue . when i start the engine is 1000rpm engine timing is 10 ( timing gun ) . y suddenlly the idle going up to 1300rpm the engine timing may be 30 or 40 . the ignition table 1 i put 0 . and the ignition correction i off it . can any ppl help me solve my problem . if i need to do again the wiring . o other .

Adamw Posted February 9, 2017 Report Share Posted February 9, 2017 Hi Liang,Can you please do a trigger scope when engine is idling. Your symptoms suggest one of your triggers may be wired in reverse. Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted February 9, 2017 Report Share Posted February 9, 2017 (edited) There are entirely to many variables for idle so with out seeing a .pcl file or a scope trace everyone would be shooting in the dark.Possible that the idle ignition table is active with weird settings?

Adamw Posted February 13, 2017 Report Share Posted February 13, 2017 The is a small artifact on your trigger 2 waveform that maybe causing a false reset. Is there some some bump or piece of metal on the trigger wheel that comes close to the sensor when it shouldnt that causes this? You might be able to increase arming voltage to ignore it, or find out what is causing it and fix it. Quote Link to comment Share on other sites More sharing options...
liang Posted February 13, 2017 Author Report Share Posted February 13, 2017 hi adamw . so you mean that , may be some thing in the distributor there izzit . ok thx alot .so now i had know the problem come out from where . thx adamw .

Brad Burnett Posted February 13, 2017 Report Share Posted February 13, 2017 Adamw, IF that was some erroneous tooth on trig 2, why does the polarity seem to change from the typical tooth to the erroneous one? Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 13, 2017 Report Share Posted February 13, 2017 (edited) Adamw, IF that was some erroneous tooth on trig 2, why does the polarity seem to change from the typical tooth to the erroneous one?I don't know what these CAS look like inside to have a good theory on that - Maybe it is a "hollow" rather than a "bump"? If the OP cant see any reason for it then it will just take some careful setup of the arming thresholds to work around it.

Simon Posted February 14, 2017 Report Share Posted February 14, 2017 (edited) Yep that extra pulse / wave would be the result of a dip in the base circle of the trigger wheel. Provided the arming voltage is above its peak voltage it would be ignored by the ECU. Fortunately at this RPM there is plenty of room but this could change as the RPM increases.

liang Posted February 16, 2017 Author Report Share Posted February 16, 2017 thank alot all . finally i slove the problem . Quote Link to comment Share on other sites More sharing options...
Adamw Posted February 16, 2017 Report Share Posted February 16, 2017 So was it the trigger? Did you fix it just by increasing arming voltage? Quote Link to comment Share on other sites More sharing options...
