semih Posted March 7, 2023 Report Share Posted March 7, 2023 hi, i want to connect my aem wideband to my link g4x v6 impreza(i want to hook it temporarily until i get link can lambda kit) i'll use analog inputs that's ok but which cal table should i use ? if i use lineer cal tables will i be ok ? if ok, i'll enter 0v and 5v lambda regards, semih Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 7, 2023 Report Share Posted March 7, 2023 Yep, use a linear cal. It will look something like below. The analog output on those early gauges were a bit variable so you may have to tweak this calibration a little so the ecu matches the gauge.

semih Posted March 8, 2023 Author Report Share Posted March 8, 2023 Thank you Adam, i guess my uego is last revised one, hope works correct Quote Link to comment Share on other sites More sharing options...
koracing Posted March 9, 2023 Report Share Posted March 9, 2023 The 30-4110 doesn't have a ground reference on the analog out so there's usually some offset. Like Adam said you'll need to make sure what you see on the gauge is also what you see in the ecu. semih 1 Quote Link to comment Share on other sites More sharing options...
Confused Posted March 10, 2023 Report Share Posted March 10, 2023 It's also likely to change every time you drive the car, too... I spent days chasing my tail with it, until I ripped it out and replaced it with a Link CAN Lambda. semih 1 Quote Link to comment Share on other sites More sharing options...
koracing Posted March 13, 2023 Report Share Posted March 13, 2023 I've experienced similar issues with non-ground referenced analog inputs from from older widebands changing all the time. Not worth it people - only buy widebands with ground reference outputs on the analog output or preferably widebands with CAN connectivity please.

semih Posted March 16, 2023 Author Report Share Posted March 16, 2023 i bought this wideband about 2016 when my maf was failed Quote Link to comment Share on other sites More sharing options...
koracing Posted March 16, 2023 Report Share Posted March 16, 2023 Personally I wouldn't let a 7 year old wideband put your 2023 tuning efforts at risk. semih and Confused 2 Quote Link to comment Share on other sites More sharing options...
Confused Posted March 16, 2023 Report Share Posted March 16, 2023 I agree compelely with @koracing - sell that AEM gauge off to some other unsuspecting person who won't ever be hooking it up to an ECU, and get a Link CAN Lambda module ASAP. I honestly spent days fiddling around, tuning and retuning the same areas of the table over and over as it would be totally different day-to-day with no other changes. (I'm just doing road tuning with log files/mixture map mostly). Once I switched to the Link module, I wasn't changing the same cells over and over each time, each drive had fewer and fewer changes to incorporate, and it ran much much better. If you're paying for dyno time and expecting the ECU to work well, it's a waste of money not just buying the right bit of kit ASAP and trying to "make the most" of the rubbish you've currently got. semih and koracing 2 Quote Link to comment Share on other sites More sharing options...
semih Posted March 17, 2023 Author Report Share Posted March 17, 2023 you're right guys, i wanted to keep as a spare(with new sensor) but i'll probably sell it Quote Link to comment Share on other sites More sharing options...
semih Posted April 23, 2023 Author Report Share Posted April 23, 2023 i can not start new reply sorry for update old thread, i want to ask another question for example i want to connect haltech wb1 controller, can i connect like link can lambda? can i use 12v and ground directly from ecu can port ?

semih Posted July 7, 2023 Author Report Share Posted July 7, 2023 bit of an update, i installed can lambda and i didn't remove my old aem one, aem reads about .7-8 higher, when afr is about 14.7, aem is reading 15.7-8 i controlled spark plugs, probably aem is the wrong one Quote Link to comment Share on other sites More sharing options...
