Hi I am considering a Greddy EMU for my AP1 NA. Is there any real difference between the Greddy harness and a Boomslang? Pros & cons please. I read in various forums there is a difference is there. The car is tracked and I'm hoping to get improved corner exit power/torque.

Thanks Bill

 

Possibly the vtec wire hasnt been wired up properly on the greddy one.

 

Can you elaborate about what needs to change between an AP1 and AP2 install? I'm assuming you're implying an '04-'05 AP2 and not the DBW cars?

I have an AP1 with the Greddy harness and all of the VTEC features work fine without having to make any changes, but it is a used harness.

 

Awesome response. Thank you.

 

The earlier greddy harness had a fault (Ap1), meaning they were incorrectly wired up and would throw a vtec CEL once you lowered vtec - i had one but it was rectified by me.

All I'm saying is if you get an old harness you could have this fault.
