Dennis Wiese Posted June 21, 2013 Report Share Posted June 21, 2013 Hi, i have a little problem with my G4 plug in on my RB26. I have a LC1 Wideband wired to the g4. Set as Wideband 1. It works. Open loop afr table is on. Two weeks ago i made a Firmware Update to 4.9.3. The Problem has been before Update and isnt fixed jet. On cll g4 only makes lean. What´s the fault?I want to run 4D Fuel Map. 3D: Engine speed over MAP. 4D: Enginespeed over TPS. 4D should not work always, but only under certain conditions: Only if TPS hasnt changed for about 1 second or TPS is falling. (only cruising or reducing speed withaout going into overrun fuelcut) Is it possible to do this with an virt. Aux.?? Sorry for my bad english and thanx a lot.

Simon Posted June 24, 2013 Report Share Posted June 24, 2013 Hi Dennis If you can post your map/PCL file we can take a look at the closed loop lambda settings.There was an issue if you were using a fuel pressure input. This was resolved and an up date to 4.9.8 would cure this. You can switch your 4D map based on an AUX but I'm not sure what you are aiming to achieve by doing this.

Dennis Wiese Posted June 25, 2013 Author Report Share Posted June 25, 2013 Hi Simon here is my map. Please take a look. OK, then i will do another Update. My aim is to get down fuelconsumption while cruising. if i set 4D to always on, i cant get as lean as i want, because for acceleration this would be too lean. If my idea is idiotic you can say so. Thanx very much! Quote Link to comment Share on other sites More sharing options...
Simon Posted June 26, 2013 Report Share Posted June 26, 2013 Are you still running the RB26 intake with 6 butterflies? If so you best bet will be to tune using TPS for your main table and use a MGP overlay table. This way at light throttle you can have lean mixtures but still maintain good mixtures under higher loads. This can be achieved as you are not going to be in the same load areas in the tables. The accel fuelling will compensate as you transition through the table. Quote Link to comment Share on other sites More sharing options...
Dennis Wiese Posted June 26, 2013 Author Report Share Posted June 26, 2013 Great. I will try! Thank you very much! Quote Link to comment Share on other sites More sharing options...
Simon Posted June 27, 2013 Report Share Posted June 27, 2013 On your wideband is the AFR reading correct on the volt input? Quote Link to comment Share on other sites More sharing options...
