hi I have 1.6 with a built bottom end a prescion 5557 turbo and 900cc injectors from injector nation and a ms2 diy unit . I got the engine in the car after a long winter and started getting the car to idle. I got the car to start and idle but when I play with my fuel settings my Afrs will not come up from 10.0 to 10.5 no matter how much fuel I take out of the table. I’ve set dead times to there specific settings. Just wondering if anybody has any idea. I’m checked to confirm that my wideband is indeed working and not broken. It idles good definitely rich for sure from checking plugs.

 

Double check your injector dead times and maybe lower them some more as a test.

 

Did you tell tunerstudio what wideband you're using?

 

I lowered it to .950 is around what I think would be right for these injectors based on there sheet. And yes tuner studio knows what wideband is being used. Both the actual gauge and tuner studio read the same

 

Check your logs for how long the injector is being kept open at idle. It could be compounded by a few different settings.

 

How do I find that log?

 

In TunerStudio, Data Logging -> Start logging in the menu. If you're not using Tunerstudio you'd have to find out yourself.

 

Okay so just a regular log. I thought maybe it was something special. Fighting flooding right now. Had it running last night turned it off to switch a couple things. And it flooded.

 

Also check your WUE and ASE, as they could bump your fuel with a cold engine / after starting.

When you can, you should post a log and your current tune.

 

Okay will do.

 

heres the current tune ive only messed with some of the fuel table at idle and dead time settings. this was the 1.6 basemap from diy I just changed injector size settings.
