I heard that there were two types of PFC you could get...one was just the older version. Does it really matter which version I get and how would I be able to tell? What are the pros and cons of each version? Any help would be great.

 

Way back in the day I had heard there were two versions. Someone can correct me if I'm wrong, but I don't think that applies so much anymore. I think the supposed "older" version wasn't as well suited to american gas, IIRC, because of more advanced timing. But you can use a datalogit to load in whatever maps you want. There's also a very early version PFC that has a slot for an extra chip, but it's of no use to most people anyway. I personally wouldn't worry about it.

 

My understanding is that there is a relevant version (with rel software) for different years (ie. 1993 - 1995/ 1996 - 1999 / 2000+)
Please correct me if I am wrong

 

Ohhh, that's very possible. I didn't even notice you weren't located in the US. Of course we only have '93-95 so we might not have the same concerns as you guys...

 

I have a 92 efini....it does have some wiring differences, but I think the ECUs are wired the same. Under the dash is where I found most of the differences.
