My modification is TODA A cam, Apexi power FC. When i install HKS twin power, i can't start my engine. The power fc is still work. After i install factory cpu, my engine can start again. I don't know why. Is the HKS twin power got some problem with the Apexi power fc?? OR i need to change some data to suit the HKS twin power?? The HKS twin power is similar MSD. Thanks a lot!!

 

Did it ever start with just the PFC?

 

you dont need hks twin power

 

i wouldn't think that you need the twin power for an NA type R especially with just spec A cams. A stronger spark is especially necessary in a FI vehicle......but not a mildly prepped NA car

 

Yes. i did with power fc.
