I seen that IA performance had a harness for plug and play with AVCS as well.
I didnt look into any reviews on it though just glancing around and came across it.
Is it true that compresstion ratio is higher on JDM than USDM?
I seen alot of debate on it but never found a solid amswer on it?
No I didnt get the AVCS. I didn't want to mess around with wiring and such that much so I went with just a non AVCS.
I looked at the engines that had it though and they where kinda out of my budget range.
