substock Posted August 10, 2013 Report Share Posted August 10, 2013 So my aem gauge is reading differently then megatune. I set the ms to what the aem instructions said per 14.7 air fuel, i was about to start adjusting the ms until megatune matched what the gauge showed but before i did that i wanted to ask here what settings people usd for the aem Link to comment Share on other sites More sharing options...
19cturbo Posted August 11, 2013 Report Share Posted August 11, 2013 how far off are the numbers? Link to comment Share on other sites More sharing options...
substock Posted August 11, 2013 Author Report Share Posted August 11, 2013 If the gauge read 12.5 megatune would read 10 and below. I am going to look through the megamanual as ivam thinking i forgot to chamge something Link to comment Share on other sites More sharing options...
Skullzaflare Posted August 11, 2013 Report Share Posted August 11, 2013 there are 2 different AEM options in the main settingsthough its also possible you have the older non compatible one. one of the older models, i dont remember the model, you had to manually program the config for the output.see if tuner studio will read correctly. btw im running a aem wideband no problems, but mine may be newer Link to comment Share on other sites More sharing options...
DieHARDmitsu. Posted August 11, 2013 Report Share Posted August 11, 2013 Try using Tunerstudio as mentioned ^^^ When you create a new project in Tunerstudio, there will be options to choose your wideband type. Chose AEM...see what the gauge reads after that. Link to comment Share on other sites More sharing options...
substock Posted August 11, 2013 Author Report Share Posted August 11, 2013 My laptop wont run tunerstudio, thats why im still using megatune. I went out and played with the car a bit and found out when i changed the code in the configurator it didnt save my changes, so i went back in and changed to the aem sensor and made sure it had saved. I didnt get a chance to pull the car out of my garage today so the next time i get a chance ill find out if it worked Also my aem is a brand new unit Link to comment Share on other sites More sharing options...

substock Posted August 11, 2013 Author Report Share Posted August 11, 2013 Yep, laptop is about 13 years oldso there isnt enough hardrive space to run it. Link to comment Share on other sites More sharing options...
pure_insanity Posted August 23, 2013 Report Share Posted August 23, 2013 i have never gotten mine to read right either. in fact i dont even let ms see my wideband or narrowband o2. if it sees either the car starts acting stupid and does all sorts of crazy stuff. nowadays i just keep it set to read w no o2 and its just all map based. i tried going in and manually setting up the values, i tried it as a generic wideband, even tried the listings for other widebands to see if it might like one of those, but no cigar. there is some info on the ms boards but i didnt find any of it that was truly helpfull. even spoke w matt at diy and his response was some people just seem to have random problems like that. lol. i am under the impression that different versions of code work better in these cases. like the msextra codes. however i had a hell of a time getting my car to act right and tuned, so now that its up and running well, im not so sure i want to go messing w it to change the code. maybe some day jut not now. i will just go without a o2.

CaliConquestAlex Posted August 23, 2013 Report Share Posted August 23, 2013 My AEM UEGO unit says that it's setup for 0V=10:1 and 5V=20:1. I had to configure tunerstudio to match this. As a result, My AEM gauge typically is very close to what Tunerstudio says. Link to comment Share on other sites More sharing options...

scott87star Posted August 23, 2013 Report Share Posted August 23, 2013 I have read that variances are due to two independent 5V sources, one on megasquirt and one on the wideband. I think you just have to figure out what you've got and recalibrate the voltage curve in the *.ini file. Link to comment Share on other sites More sharing options...
jszucs Posted August 23, 2013 Report Share Posted August 23, 2013 Pure I am betting you have the exact same circut fried on your MS that was on mine. Is it a MS2? If so they had some problem with the processors for MS2 for awhile. Mine would not take a wideband 02 value to save it's sole. Sent it to Scott to fix and back in biz. As for the voltages being off. DO NOT put your o2 heater and 02 sensor grounds together as it says. Ground the sensor to MS ground, and ground the 02 heater seprate. Also DO NOT power o2 heater and 02 gage off the same power, and make sure 02 power is not powered off same power as MS ether. Link to comment Share on other sites More sharing options...
substock Posted August 26, 2013 Author Report Share Posted August 26, 2013 After i reset the megatune config file it appears mine is working fine. Ill be playing with it more after i get the car reinspected (failed lasr weekend due to bad wheel bearing and the rear main seal leaking), but i have been paying more attention t the gauge the megatune at the moment Link to comment Share on other sites More sharing options...
