Cruise log, need some help w/ 02 sensor

I still think your injector settings need to be changed back to your 1200's then zero out the dead time . adjust the maf at idle to get your air flow per rev to .25 . then add dead time to get your combined fuel trim to plus or minus 5 percent. the logs show that your o2 isn't cycling right. when you set the ecu up to read 880 cc injectors when you have 1200 cc injectors will run rich as hell .but thats just my 2 cents.

Hey, it is doing better, I had someone look at it and send me a tune. they are set to 1200's, but the problem i was having was i was not adjusting my mafcomp far enough, I have a hacked 1g maf and the mafcomp had to be way up there, here are a couple logs, today and tomorrow though I am swappying out injectors for 1250s and getting an e3 turbo on it.

Edit: I dont think those are the right logs, Right settings but sometimes my FT reads 28-29 (1st log), but most the time it is between -8 and 4% which can kinda be seen in the second log, but my airflow is different, I think idle was al il high then blipped the throttle to bring it down. idk ill get some more logs.

New log needs looked over, thanks. Current injectors are 120 lbs, which is 1260cc's. Current turbo is now an e316g.

Adjust your injector size to the actual size .you have 1260's ,but link says you have 1186 cc , your talking almost 100 cc different . get the car to idle around 750 to 900 rpm or so. from what i see you're idling around 1100 on up. then adjust the maf comp by watching air flow per rev. you want to see .25 or real close to that .drop your dead time down to 300 micro seconds and adjust up from there watching your combined fuel trim to plus or minus 5% . remember you want it warmed up to operating temp so you can maintain some consistency. that should get you in the ballpark to start.

I had it adjusted to 1260s I thoiught maybe it didn't save for some reason. Ill try that tuesday I'm out of town for holidays now.

Most recent log as of yesterday, looks to be dialed in all right, injector is set to 1260's airflowperrev is at .24-.26 and fuel trim is in the -7.xx-2.5x area. The weird thing is though that the o2 doesnt cycle at idle, just stays at a set voltage in the middle. but cycles at a cruise. is this ok if my numbers are reading right?

you have a trouble code in your DTC's . engine coolant temperature malfunction. I'd check that ### that little bugger can cause problems.

Ya, it only is on sometimes it is a loose connection, it is just a stored one. Would that still make a difference? I think they broke the connector and now have it all taped together.
