Safc and tach adapter

[G9S6T]

Hey guys I searched and even pm'd some people I didnt get my answer. Sorry If this is an already answered question but I was just wondering since our cars have a coil pack do we need a tach adapter to read rpms' with a safc. I ask this because I have alot of buddies with srt-4's and they said they needed a tach adapter because they dont have a distributor, they have a coil pack. Thanks for the input guys!

For maft and safc you grab the rpm signal from pin #58 on the ecu. There's also another place under the hood but I can't remember.

I got the tach signal at the ecu on both my 1g and 2g.
