jdm h22 fuel cut

[Ludin203]

i just did a jdm h22a swap and it runs fine untill i hit top speed... it will only max out at 120 or something around that and then it hits fuel cut which is wierd.

i cant figure out why it does this, when i did the swap i used an h23a1 fuel rail and regulator because the h22s fuel rail is backwards but the rail looks smaller and its running on the internal coil distributor it came with. so those r the only things i can think that would effect it as far as it not letting it go as fast as it should up top but does anyone have a definite answer or an idea that might help me solve this?

thats the way the ecu is programmed. i had the same engine with the p13 and it cut off at 120 also.

It is called speed limiter

It is called speed limiter

good going,i guess he needs to remove it then to kick it into vvvvvtaaakkkk mode

P13 ecu's suck there are so many more options using a different ecu base
