I dont know whats the problem with the ECU...I have 2 ECU one is a P13 and the other one is P28 Hondata Base map..The P13 I cant take it over 7000rpm and the P28 Hondata i can take it up to 8000rpm but when i take it high rpm and then stopped at the light my car either shuts off because the idle is low or my car idles at 500rpm then drops to 200 then bounce back up also when i drop from 3rd to 2nd my car rpm bounce and im at full throttle but it does not go cuz its jerks...can anyone help me with this problem

no codes at all

 

Holy run on sentence batman! The only thing I understood was when u said you took your h22 to 8k. Why would you do that?

 

sorry im just tired from swapping the motor in today..i took it up to 8000 even though my redline is 7800 but still im more concern why my idle is so low after i take it at high rpms

 

Correct me if I'm worng but last time I checked the red line for an h22 was 6800 was it not? Have u cleaned out the iacv? That is usually the cause for a surging idle.

 

i mean 7200 for the jdm h22a thats the redline and i already clean the iavc

 

Have you bled your cooling system? Air in your coolant will cause your idle to fluctuate.
