HELP! MS3x issues!
 

Hi guys, I just installed a MS Labs Ms3 basic, CAN box, and innovate LC-2 in my car and shit hit the fan. The car idles fine, when the A/C is not on. With the A/C on, the car wants to die every 2ish seconds.

My AFR stays at 14.7 all the time. And it feels like I'm getting bad fuel cut at 2k+ rpms. Like the car isn't drivable at all. This is with A/C on or off. Any ideas?

Datalog and MSQ.

What is MSQ?

Here is what I have. I can't open them for some reason

Buler? Anyone?

Afr at 14.7 at all times? On the gauge and TS?

Also, MSQ is the tune file.

14.7 at all times on TS. I don't have a gauge yet.

If the CAN module isn't getting a signal from the wideband it will output 14.7 to the ecu. Might want to start there.

It has to be getting a signal. It is connected with a serial cable and hardwired for backup. I know its getting power because I can see it light up.

you should not be seeing 14.7 all the time. Get a gauge to confirm.

For the AC, you will need to tune the idle to get it working well. there are some good resources for it if you search it out.

Ok I will search. I didn't know it was something that I needed to tune.

Here is the MSQ:

Delete this thread. I need to read up.

lol. so what did you find?

I deleted the CAN devices under project properties and I got my AFR readings.....dunno. Also, I was a dumbass and tried to autotune before I got my (correct) AFR readings and that screwed up my fuel table, which was causing the drivability issues.:facepalm: So I copy and pasted the basemap fuel table into my current tune and everything is good. Still need to tune my start up and idle.

Here is my current msq
