If I use an analog to CAN converter the values I get will go into a virtual analog for the ECU to get data from right? Also are there any limits to the CAN stream such as IDs? I’ve heard that you can only have 8 things on Link’s CAN bus.

I was going to convert the analog output from the sensor to a digital output with a simple analog to digital conversion. Wouldn’t this convert the value coming from the sensor to binary? I don’t think I would have a usable table with binary. Edit: It really sucks too because I already have my Monsoon X with only 4 an inputs which are being used. My harness builder said I could drop my fuel pressure sensor for the meth pressure sensor but that could be dangerous if my fuel setup breaks. I would love to convert it to CAN but I’ve heard the CAN stream can’t handle much at all. Im running a few CAN devices including a Motec PDM, Digital Dash, CAN shift light and a Motec CAN keypad. I don’t wanna risk spotty frame delivery with the CAN stream so I didn’t want to add to many devices. If you think CAN would be the best option then i’ll make that work:)

How would I convert the 5v output from the pressure sensor to a frequency output?

yeah i’m out of analog inputs. I definitely would not feed a di analog voltage but i’m converting the analog signal from the pressure sensor to binary using an encoder.

Is it possible to use a pressure sesnor (methanol) and convert its analog output to a digital input on my ecu?

Is Link's CAN bus system limited by anything? I know can has a throghput limit of 1mb/s but is there a certain number of devices it can support (I saw 6 on another forum which seems absurdly low)? I'm wondering becasue I need to control my mentanol pump via CAN or something else (PWM via SS relay). I want to be able to control pressure and also switch tunes if the meth tank is empty. I only have a digital and aux free but CAN is used for nothing but my digital dash. If I can control it via CAN I was thinking about having a CAN gauge, my digital dash, a map switch knob and a can keypad for antilag etc.

I ended up talking to my tuner and he remoted in and helped me tune it for a basic drive. He said I needed to check my wiring and that it was likely the connection or o2 sensor gauge/sensor. edit: I checked my sensor and did a free air calibration. The afr changes by 5s just by reving. Im getting a new sensor but I didn't really like the x series gauge because of the useless aemnet functionality. I might get an analog only controller.

Yes here it is. I have 2 wires on my harness, one connects to the ecu and one goes to ground. I got it working but the ecu stops receiving values from the gauge. Plus the values are wrong. For example when started the gauge will read 1.2 lambda and the ecu will read .6 then after a while the ecu stops receiving data from the controller and it sticks to 1.3 lambda.

Yes the input for the AFR is analog 3. I set it to that and changed the calibration to AEM X series. My wiring goes like this: power for the aem controller to a 12v source, ground for the controller to the grounds for the ecu, brown and white analog outputs from the controller to my harnesses wideband inputs. My lambda value on the controller says 1.0-1.2 but my software is telling me its in the .6s. Also after about 10 seconds of the links lambda gauge working the value jumps to 1.3 and doesnt change values unless I power off the gauge.

I have absolutely no tune on my 4age except for the startup map my wiring harness guy did. He told me to get an AFR gauge so I did. It's a AEM X gauge and it causing me some issues. My wiring harness has a wbo2 input with a white and brown wire but when connected to my sensor gauge it gets no input in the ecu. I'm running a monsoonX btw. The gauge reads 25 afr at idle but my idle doesnt work at all. Any help would be appreciated as the engine is brand new rebuilt.

Nope I wired it to the other brown wire in my harness.

Nope still doesn't work, the error value is the only thing displayed on the digital gauge. The gauge might be putting out a low voltage? My output wires from the ecu connector are ANVOLT 2, should I be connected to CAN H and CAN L?

Here you go. Edit: I also forgot to mention there is a little white smoke coming from the exhaust. Im pretty sure it has a bad head gasket. 4ag_started_1.pclx

I just connected the can wires from my gauge to the analog ones to my ecu and the values for lambda are still different. Any suggestions?

Wait but doesnt that mean that I need CAN Lambda?
