Aedan Glasby Posted October 12, 2014 Report Share Posted October 12, 2014 Hi All, I have an R33 skyline that's recently been tuned with a Link G4+ pluginÂ (GTS/GTRLink). I noticed that the AC controls were reversed in that when the AC was engaged via the dash, the AC would be off and then when turned off via the dash the AC would turn on. I looked into the DI settings in the ECU and changed the "on level" from high to low which seems to have fixed this and the AC controls are now the correct way around, however it seemsÂ in thisÂ modeÂ that the AC request is intermittently turning off and on every 20 seconds or so with no evident reason why. IfÂ I swap the "on level" back to high, the AC controls are reversed again but the AC remains on consistently (and sometimes if the AC is on long enough in this setting, it will refuse to turn off). I've played with various combinations of the polarity and pullup resistor settings but it doesn't seem to make any difference. Any idea why the AC would be turning off and on when the AC controls are the right way around? Quote Link to comment Share on other sites More sharing options...
