e3mand Posted May 15, 2011 Report Share Posted May 15, 2011 Hey guys, Im having a problem getting my AFRs to match on the guage and in megatune. Have any of you had this issue? I need to find out how to get them both to match or at least get really close. I am using an AEM Eugo, If you guys need any other info that I havent listed on here just let me know and Ill get it right over to you. Thanks Link to comment Share on other sites More sharing options...
psu_Crash Posted May 15, 2011 Report Share Posted May 15, 2011 You need to open the configurator and set up Megatune for your type of wideband. Do that and things should be all good. I think I do remember using something other that the AEM UEGO setting to get it to read correctly though. Try out the generic 0-5 volt linear setting too.

jonboyb Posted May 15, 2011 Report Share Posted May 15, 2011 In Megatune also need to go to "Tools", "Calibrate AFR Tables", then choose AEM Linear in the drop down Link to comment Share on other sites More sharing options...
e3mand Posted May 15, 2011 Author Report Share Posted May 15, 2011 Ok cool thanks Ill try all that. I know that I have the AEM Eugo chosen in the config settings but obviously thats not working lol Link to comment Share on other sites More sharing options...
Starwolf Posted May 15, 2011 Report Share Posted May 15, 2011 Hopefully you have the digital version of the AEM wideband...I still have not got the analog one to read right... It just isnt in the drop menu and none of them work correctly. Link to comment Share on other sites More sharing options...
NotStock88 Posted May 15, 2011 Report Share Posted May 15, 2011 (edited) Same issue here - my Innovate afr gauge, and the dyno i go to, is reading the same (accurately) - yet when i datalolg in MS the afr's that are being logged are not matching what I see on my Innovate gauge. I have the MS set to linear, the correct wb selected and have also manually entered values direct from innovate manual yet still cant get my ms logs to match the gauge at WOT. scott87star said he has seem similar issues, hope he chimes in here.

jonboyb Posted May 15, 2011 Report Share Posted May 15, 2011 I run the EUGO in all my MS cars and the AEM-Linear setting works perfectly. On-screen/datalogging matches gauge exactly. Make sure you're using the 0-5v wire and not the 0-1v one from the AEM unit. Link to comment Share on other sites More sharing options...
StarquestRescue Posted May 15, 2011 Report Share Posted May 15, 2011 Does your gauge have a switch on the back to set the options on the analog output wire?Configuring Calibration OutputsThe AEM default position is (P0). When set to (P0) (Figure 10A), the gauge displaysAFR values. (P1) is the same as (P0), except the gauge displays lambda values. Thesesettings (P1 and P0) implement a linear calibration with the most useful voltage rangepossible (0-5V). The AFR calibration (P2) is linear and similar to (P1) with a smallervoltage range (1-2V). The AFR calibration (P3) emulates the Autronic Wideband O2Sensor calibration (0-1V). The AFR calibration (P4) emulates a non-linear Nernst Cellcalibration (0-1V). Refer to the Table 3 and figure 9 for specific calibration details. Link to comment Share on other sites More sharing options...
e3mand Posted May 16, 2011 Author Report Share Posted May 16, 2011 Hey guys thanks for all the replies, I actually got it fixed just a couple hours ago. I had AEM Eugo selected in the config page and it said non linear so I just switched to the option that said Linear AEM and BAM!! it matched perfectly. So thanks for all the help again guys.
