Dave Kriedeman Posted May 15, 2014 Report Share Posted May 15, 2014 Hi, the drive trim will always work, even without a neutral park or gear switch being employed. You should leave this setting turned off, to 0 if you have no DI to activate it, otherwise you will always have the trim amount selected active to the fuel Main Table. Can you post your PCL file regarding the aircon so I can test the function of the inputs , outputs etc on my simulator. Otherwise you can check the status of everything related in the runtimes list hit F12, Look at digital inputs to check the A/C request is functioning, check aux outputs to see if the clutch output is activating etc. Regards Dave.

07_wrex Posted May 16, 2014 Report Share Posted May 16, 2014 I have kind of a similar question. When my A/C kicks on, my AFR goes super rich. 10.0-10.4 to 1. I have all three of the mentioned fields set to 0.00 ms. It doesn't make a difference. Is there another table? or can I go negative with the trims? Hmm...Apparently it will let me enter a negative value. Haven't tried it on the car yet though. Thanks, Sean Quote Link to comment Share on other sites More sharing options...
augusto Posted May 17, 2014 Author Report Share Posted May 17, 2014 The trim valeu can be adjusted from -2.00 ms to +2.00ms. This serves do decrease or increase to value a/f ,when the air conditioner is on. And this adjustment is not working in the ecu vipec. I m traveling so can send pcl Excuse my poor english.

Dave Kriedeman Posted May 17, 2014 Report Share Posted May 17, 2014 Hi, you must also remember with the different loads applied that the ignition timing and main fuel table values and idle speed tables etc will also change as the load varies with the differing conditions, The trims are only part of the equation. Regards Dave. Quote Link to comment Share on other sites More sharing options...
augusto Posted May 18, 2014 Author Report Share Posted May 18, 2014 Dave My car runs at idle with the a / f 14.7:1 perfect. When you turn on the air conditioning the mixture goes to 17:1 and this time the adjustment of Trim Air con has to make this correction. However, this setting does not work can range from -2.00 ms to +2.00 ms, the A / F does not change. But if I do the same thing in Eng Fan trim function and the engine fan is turned on the A / F change at the same time for more (0ms to 2.00ms +) A / F goes to 12:1 or less (for 0.00ms. - 2:00 ms) A / F goes to 17:1.

Simon Posted May 19, 2014 Report Share Posted May 19, 2014 If you can post you map that would be great as we can check this on the bench relatively easy. But as the load will have changed you will have moved to a slightly different area of the MAP and you might require some adjustment of the map to compensate.

augusto Posted May 19, 2014 Author Report Share Posted May 19, 2014 Simon Sorry, finally managed to attach the file. Augusto. Quote Link to comment Share on other sites More sharing options...
Simon Posted May 21, 2014 Report Share Posted May 21, 2014 I have given this a run on the bench and the trim is working as expected. The trim is applied only when the Aux out set for AC clutch is active. This does have a delay after the AC request state changes. Quote Link to comment Share on other sites More sharing options...

Guest Posted May 22, 2014 Report Share Posted May 22, 2014 Good morning Augusto, Simon is away today. Can you please post a PCLog of your vehicle at idle and then activate the air conditioning. I will look in the log to try and identify why your setup has a problem and why Simon had it working here when he tested. Scott Quote Link to comment Share on other sites More sharing options...
