Default N Log check Map 3 - 10-10-2020, 09:57 AM

Hello,

I have been running map three for a couple weeks now. Just wanted to get a log check to ensure everything looks okay to you guys?

Thanks!

Had some problems this weekend. For some reason now I am getting a really bad hesitation at around 5500 rpms? Makes me wonder if I am having the fuel pump issues others have reported? I tried to catch it on some logs.
I also tried switching to Map 2 and it was still there. I think I am going to run this tank of e30 empty and see if it is still there with just 93?

I'll take a stab at this...
Your fuel pressure looks OK to me. What's happening is it looks like one of your fuel wires is not making connection. There is a huge difference between AFR and AFR2. Check wires. Just a rookie stab but I think I'm right.

Thanks! I will take a look. I was under the hood this weekend working on my heat shield for my intake and other stuff so maybe I bumped the fuel pump plug? I will look around under there after work.

Another question, is AFR 1 & 2 the 02 sensors? If so I have an XForce down pipe with the 100 cell *** and 02 defouler. It sometimes gives me a CEL, so maybe that is the difference you are seeing?

I'm not sure about the down pipe but your log is off. Maybe I'm looking at it wrong but a trim of 47 on one side and 0 on the other isn't right. Neither is an AFR of 13.2 on one side and 1.7 on the other. Both sides indicate something is off, a loose wire, bad connection, ect.. Also, I'm not 100% but I *think bank 2 is passenger side.

Probably high fuel pressure dropping too low. Add in the JB4 fuel control to lean out the AFR and get fuel pressure up.
