99 dx car redline at 5000 with ex ecu... help
 

i got my hand on a y8 ecu n use it on my y7 car i also use the y8 manifold everything is ok but my car cut off at 5000rpm.... do i need to use the y8 distrb. to make it run right?help....

stock y7 ?

sounds like a rev limit cuz it's missing certain sensors.. your CEL is on right?

also fr my understanding the distrib. is wut control the rex. limiter rite? but im not sure im new to this honda world

the y8 ecu is looking for a knock sensor too...why would you put a y8 ecu on the y7?

Yes a person bought a Y7 ecu from me, and tried to use it with his harness, and it runs bad, but the Y8 ecu had a rev limit when about vtec kicks in.

what car do you have it in? an ek?

your IACV is wired wrong for a y8 ecu if your using a y7 tb.

i had the same problem before i used a gsr ecu on my dx. it will stop at 5 grand. what i did to get rid of this is bought a fuel pressure regualtor and cranked up the psi and then it worked fine for me hope its that easy for u.
