Ok question for yall. Just got a call from my exhaust guy and when he mounted my rear 02 sensor bung he didnt realize I had the spacers on it so it wouldnt fit. Does it matter if the wideband is behind the rear 02 sensor? They are gonna be really close together anyways as I am having both wiring harnesses go through the same hole to the cab. I told him he could probably put the wideband in that one then mount the rear 02 just ahead in front. I dont see and issue with this but thought I would run it by you guys

 

Thanks Link for the latency link I printed out the whole thing sounds like I am on the right track

 

02 cheater



FMIC Lurking. The charge pipes stick out the bottom but oh well



front end lines back up pretty good


pic of the engine bay, it looks a little different now than in this pic ill get pics of that too


battery in trunk


blue underdrive pulley


massive 3" Downpipe


FMIC and slim fan

good stuff man. You clean that engine bay up a little bit? hows it run?

 

Yup this is just the basic install it looks a little cleaner now after these pics were taken. Runs awesome I must say but still waiting on a phone call that my car is done at the exhaust shop, then I can start the real tuning.

 

So are you using the stock uicp? Did you cut it? I ask b/c it runs under the intake in your setup.

 

nope didn't cut it that's just where it. Sat after it was all done

 

Ok so dude at the exhaust shop called me right before I had to go to work so I got a ride to pick it up and had to go straight to work. He said he couldnt fit the clip of the wideband through the hole going to the cab so after work I got the rear 02 and wideband hooked up. Although it was pretty late when I got it done so I started her up and just let her idle for probably 2 mins. Its telling me cold idle is measuring about 16.1 16.2 afr so still a little lean looks like but I guess I will have to drive it tomorrow before work and see the afrs on the road. Isnt the afr supposed to be at 14.7 though? If so wouldnt this mean my trims should be wayyyyy positive?

 

I think I am almost there, my idle trim is at about +4 and change and my cruise trim is around -1 to -3. Gonna bump my latency up one or two increments and see if that gets my trims closer together then maybe bump my scaling up one increment. Here is my injectors as of now, if anyone out there that has tuned there 440cc injectors see an issue please let me know.



One issue I am having is my wideband logging. I have everything hooked up right and setup up correctly but for some reason evoscan will log my afrs fine for maybe a minute or 30 secs or maybe 5 minutes and then it freezes. everything else continues to log like normal and my AEM Uego gauge clearly displays the changing afrs but the number in evoscan stays the same???? Anyone else experience this before?

 

Did you change your maf scaling back to 412 yet?

 

Dont think I will be going back to that scaling, its looking like I will be around 330 for my scaling

 

Oh wait maf scaling? Havent messed with that

 

So got my trims pretty close,
low: 5.85
Mid: 4.10

dropped my scaling from 344 to 336 gonna see if I can get a little closer to zero.

So from my research sounds like evoscan 2.6 has uego logging issues but cant find where to drop back to 2.5 anyone know?

 

Change the injector scaling back and mess with the fuel maps, injector latency, and maf scalings and you should be fine. My setup is near identical to yours.

 

Working on that now What version evoscan are you running?
