Would like MS2 or better if possible. Just seeing what people have before I buy a new setup. I would like if it was already setup for 3-wire IAC and 3 coil wasted spark, but not a big deal if not.
When you say 55pin MS, you are looking for a plug and play setup? I've got an MS2 with 3 wire iac and set up for waste spark, but it's not plug and play.
It is hard to beat a new diyautotune PNP/ non PNP MS2 for the price, personally I would only buy new. The quality of assembly is top notch as well as support. Those guys are great.
You should just bite the bullet and go MS3x Do you have prior experience with MS?
