I just dropped in a B18c1 into my DX bubbleback.
I switched up the P72 ECU (that I just got with the GsR that seemed to pull from 6000-8000rpm) and tested out my old P30.
There was no difference!?!
Not only did the P30 seem to have just as much torque but the P30 still opened vtec @ 6000. When for years that ECU always pulled from 5500-8500.
Now I'm a bit confused!
So I have 2 questions;
1) Why would the engine not recognize the difference in ECU and engage vtec
@ 5500 like it would in my SiR.
2) How can I find out/ get my GsR secondary to engage?
(Because obviously my P72 isn't doing it.... or else I would have felt a low
end difference when I put my P30 in. Right?!?!?)
Keep in mind I have no engine light or codes.
Appreciate the input ~ D
