Changed a few things, wired the IAT, rewired the wideband to run to the ECU direct instead of through harness and also realized I was using the brown output wire (what I understand is narrowband emulator) instead of the yellow output wire. Was having some very seemingly close cranking but now I have this. AFR constantly reads 7.4 on TS.

Edit: just tested for voltage on the yellow wire and there is nothing

In looking at older forum posts I am seeing a lot of people talking about Analog 1 and 2 for the wideband but in both TunerStudio and Logworks I only see 1 set of imputs I can change which are both set to 0V=7.35 and 5V=22.39.

Well, I got my car running thanks to a knowledgeable friend who could do it without the wideband working as it still does not work. Had it reading correct values in Logworks (through the other connectors on the controller) last night but still didn't correctly read in TunerStudio. Now after moving the ground for my LC2 controller from the cabin to a ground shared by the ECU as advised it now reads incorrectly on both Logworks and Tunerstudio. In addition, my can bus pins that go to my gauge do not transmit any info and my IAT which is wired in through the MS2 options port only shows default values. Starting to think this is an issue with my options port...

Can anyone confirm that the pins on my extra connectors for my MS2 look like they are seated all the way? I’m just now realizing it’s not just my O2 sensor that isn’t reading properly but everything that uses this options port (can bus, IAT)

Not what so ever. You won’t see any of the pins on the back side, and they’ll nearly be flush on the front. I use pliers to grab the pins and pull them through

Ah, that makes sense, I've never built my own connector and hadn't seen any pictures on forums so I had nothing to go off of. I hope this is the issue.

Pulling the pins through worked to get things to read in tunerstudio, thanks! Now my O2 sensor will not read correctly again. My settings in LM Programmer and TunerStudio are 0v to 7.35 AFR and 5v to 22.39 AFR. LM programmer to multiply off of Ethanol (9.0) reads 13.8 or so AFR at idle in Logworks, but reads 21-22 in TunerStudio.

What’s the voltage on the wideband signal output wire. Without doing complicated math, 13.8 is about 62% of 22, so I think the voltage should be 62% of 5v, or 3.13v. If not, look into the wideband, if it is, look into TS settings and/or wiring to MS.

Yeah so my meter reads a constant 5v from the yellow wire, I assume this a problem with the controller part of my LC-2? It seems the serial cable read fine as it was giving me the 13.8.

Iirc you can change the calibration of the 0-5v outputs. Try the other one, and/or try editing them.

Ok I can try editing them, do you mean in LM Programmer or TunerStudio? Because from the serial port reading of 13.8 that would seem like a realistic number right? So I'm just not reading correctly in TunerStudio. Im still not exactly sure what AFR reading I want to be seeing.

If you’re feeding TS 5v, it’s reading correctly at 22. If you want, you can turn TS into a volt meter, by changing the calibration to 0v/0afr and 5v/5afr.

I guess I’m confused at what’s reading 13.8. Is this when running? Does it change if you change fuel settings in TS?

The thing reading 13.8 is LogWorks, which uses the serial cable output of my LC-2 controller, this is when in LM Programmer I set the multiplier for 9.0 for ethanol and have the voltages and AFR set up as I said in one of my previous replies. Yes that it when it’s running, and I believe it changes when fuel is changed but I don’t know enough about TS to make the correct changes. I’ve just been using a more experienced friend and while he was able to get it idling he is stumped why my controller will not read correctly also.

Decided to just install the AEM UEGO I had ordered to eliminate the possibility of the controller of my LC-2 having issues and it reads 17.8 at idle and even when I rev the car. I really don’t know what’s wrong at this point.

Is the car just running too lean?

Is it mandatory the wideband is grounded at one of the ECU accessory ports? I have it grounded near where the stock harness is grounded.


Edit: grounded the wideband at the ecu and this didn’t change anything, the AEM gauge reads 14.7 while heating up and then just rises to 17.8 and then - - - once it’s done regardless of the car being on or off.

Had a friend independently verify my afr is correct with an o2 sensor that only requires 12v power and now even after installing a new AEM UEGO, it does not read correctly. Even on the gauge. It warms up displaying 14.7 and then rises all the way lean wether the car is running or not. I even tried grounding the gauge on the battery but that didn’t change anything. This photo is what the gauge displays (3 dashes across the middle - - - and 17+ AFR.) Setting up tunerstuosio with afr 0-5 to act as a voltmeter says it is just stuck at 4.40. Is the sensor bad? I find it really unlikely that I would be 2 for 2 with bad sensor with this and my Innovate having the same problem.

Edit: just did the brake cleaner test on the sensor and the reading did not change at all, it has to be bad right?

Edit 2: did the brake cleaner test with the sensor from my innovate and it read correctly, afr dropped to around 10 once in the cloth with cleaner on it. AEM sensor was just dead out of the box

Is this a 1.6? I’ve seen o2 holes that are only big enough for narrow band sensors, or just plain poorly drilled, damaged sensors every time they’re threaded in.

Actually as I found out in my edits it was just the O2 sensor from the AEM kit being bad out of the box, re-wired in my innovate wideband and controller and it reads perfectly. Also the hole it was threaded in was krakens exhaust so I don’t think it was that that damaged it.

Hey, back with more issues haha...

The engine has been running rough since it was put in and I found out it was because injectors 2 and 4 weren't firing. If I go into test modes and test each cylinder individually with a NOID light only 1 lights up. But If I test all of them together 1 and 3 light up like when the car is running. I have checked for continuity in the wiring in the injector pigtail and through the harness from the connector to where it plugs into my MS2. I feel like this has to be a software issue as I didn't make any changes to the wiring and the Botsch injectors I got are straight from Kraken and should plug right in. Does anyone have any idea what could be wrong?

Edit: If anyone comes across this thread with the same problem I followed these instructions: Basic / Load settings > Engine and Sequential Settings > Injector Drivers > set to additional drivers
