My civic si changed the head to finish the program idling unstable

My 2015 civic si has a new RBB head, buddyclub camshaft number two, Acura 410cc fuel injector, Skunk21.8 l intake manifold, and now that I've written the program, idling speed is going up and down, and I'm new to all of this, i don't know if anyone can give me better advice.

Here are two log, and the car's program, can you help me find the following problem, the programmer's nozzle size did not change for me, but the fuel injection time has changed, i have tested the car no place leakage, but the fact is that idle high and low, not to achieve the target idle speed.
Can you help me look at the map, explain where the problem, thank you.

This is my idle speed modified to 900 after the figure, become a lot more stable.

Hello Gao,

I would check for vacuums first to see if that may be causing the idle issue. It is common to have vacuum leak after an install. Once you have confirmed that no vacuum issues are present you can move to the calibration file.

Thank you for your reply, Leak Problem I have ruled out, no vacuum leak, I feel is the fuel injection map settings, and fuel injection pulse width settings.

Have you modified the calibration for your upgrades injectors? Also, I realized you have a cam installed. It is possible the cam does not like to idle to low thus why it idles better at 900rpm.

I Am a novice, I do not understand these, this is a programmer to help me set up, fuel injector calibration I am not sure whether the correct

This is the data that I drove for a period of time after I went out today.

Now the car drive strange, always feel the power is not good, especially when the shift will be re-open the throttle will not have the strength.

I will review the log when I get a chance. You are going to need a custom tune to optimize it for the cam. The car might need fuel adjustments after you modify the data for the injectors.

OK, thank you for your reply, please take a look for me. I am afraid that the car will be in danger, now the car has been throwing a code name, P0133

I looked over the datalog and it seems the car is running lean. I modified the calibration file you provided to start as a base. When tuning these cars you want to set them to open loop, turn off Vtec and dial in each VTC table.

Create a normal log with the modified calibration file.

Received, thank you for your help, I will pull the data to you as soon as possible.

When I write this version of the program, the car will stall and won't run successfully.
