It will cause your VE table to be out off wack and affecting your idc but to a point. Where's your target afr during the high idc?

11:1 but that's spraying meth , I shut it off and it leaned out to high 11s. My logs are saying idc are 145%. I can't believe that my airflow per rev would be causing this much fluctuation?

All that was changed was my new motor, my old motor at 30 psi was seeing 70%, after the motor died I pulled it out , rebuilt it and now I'm seeing 145% at 20, I'm going to check all of my connections on my fuel pump wiring, send compressed air through my fuel lines, clean my fuel filter and fix all my vacuum leaks.

I'm not saying it's 100% of your problem but it's something that is off and should be corrected. I would keep the methanol off until you get the car tuned at 20 psi perfectly. Afterwards you can turn it back on and up the boost.

I think ive been going about this wrong. I have good fuel pressure yes, but that does not mean the volume of fuel is correct. There must be some restriction in my system, either a clogged filter or another issue.

I just had a epiphany, looking through my log I noticed a code, engine coolant temp sensor. The check engine light isn't on but I forgot to clear the code when I fixed the wiring. Could this be causing the computer to keep the injector running longer to richen to motor? Basically limp mode?

I would think if your motor is running too rich, that would be reflected in your afr.

well technically the motor is running rich, the motor doesn't run lean at all......its just my injector duty cycle. How does the engine protect the engine when a code is triggered? Pull timing and richen the mixture? It was just a thought as I noticed the code in the log.......Everything is my car is new, nothing was changed, just a new motor. When I pulled the motor the clip on the coolant temp sensor broke off and I rewired it. I thought the code was clear, but if you look at the datalog its in the dtc box. Im just trying to think of things that changed ...........

I just looked at your log real quick. Your airflowperrev is off. Your around .36 at idle. Should be around .25. This means your speed density table is out of whack and your global fuel adjustment also. Use your ad table to get it to .25 then readjust your global to bring the wideband to 14.7.

To get the airflow per rev down I need to adjust the speed density table correct? The lower the numbers mean im telling the computer to lean out the mixture yes?

Yes. To get the airflowrev lower you reduce the numbers in the sd table ( where your idle is). You will then need to adjust your global to compensate for the lean mixture (assuming your inj deadtimes are correct) . Your entire sd table will be off after adjusting the global so you will have to retune your car. Just follow the tuning guide and it goes quick. Hopefully this helps you.
