after reading the manual a million times over I figured out how to edit tables and add rpm and load points. I messed with tps and was able to get the afr to 11 at about 3 psi. My only complaint is the transmission shifts down like the pwr button is on. I’m probably getting terrible mileage I will mess with maf next. With the extra injectors it goes pig rich at wot. Like 10 and my afr doesn’t read lower so I’ll adjust those as well. It actually is not nearly as complicated as I thought.

has anyone ever used the narrowband simulator feature on the aem wide band? According to chat gpt you can clamp the signal to read really rich when boost starts sending it into closed loop without weird transmission behavior. Just curious if anyone has ran it this way.

Here’s an update. I’ve put over 1500 miles on this setup and it has been great. The stock ecu keeps fighting the xede at part throttle. I disconnected the 02 sensor and afrs are perfect. They drop to 12afr 1-3psi then 11 afr 4-7 then at wot 10psi 10 afr. Idle afr is 13.8 so I’m going to tap the map sensor and try and make it disconnect the 02 as soon as it sees boost so idle and cruise still trims fuel.

They make boost switches that activate at certain psi i believe. You could run a o2 wire through it to disable the o2 at a certain psi.

I ordered a switch hopefully it works as intended I could only find one that kicks off at 4 psi that should be fine. I’m thinking I could probably make a map for e20-e30 and get some more timing out of this. Afrs are in the 9s at wot so I have plenty of fuel

Does anyone have any experience running an emix? I’m wanting to know if what mix I would need to run to run stock timing. I remember when I put octane booster in I was getting no knock and I know e85 is super knock resistant

Well I got the Hobbs switch hooked up and it works flawlessly. I set it to around 6-7 psi and the second it activates the stock computer stops trying to pull fuel when my aux injectors spray. It also doesn’t throw a code somehow. This might be an easy work around for smaller turbos that come on earlier.

Does it kick a check engine light?

I drove for about an hour activating the switch a lot and it hasn’t thrown one yet.
