What's the difference between a tfi for an auto or manual?

[Nottoofast50]

I noticed they sell tfis for automatics and manual transmissions. I have one for a manual on my car(and it's an automatic) and didn't know if that would affect performance or not. What's the difference between them?

ok u mean the ignition control module on the dist. and i dont know what the difference is but i just replaced mine like an hour ago. ok by the way heres a really funny story bout when i was replacing it...

so im out there replacing the icm or tfi or whatever you want to call it, and my heads under the hood and all of a sudden my car jumps at me and damn near knocks me over! yea im not joking...
so i look and some stupid ass asian bitch (no offense) had backed into my car!!!! remember im in a ****in apartment parking lot and i had just said hi to her as she walked by so she ****in knew i was right there, so it was kinda unbelievable!!
well long and short she had a huge dent and my ****ed up paint all over her bumper. luckily my car is all ****ed up on the outside so i didnt care at all. so i acted all bummed out and said she ****ed up my car and made her give me $100. haha im a hustla!
sorry had to tell that story!

so yea i dont know what the diff is but when i got it at kragen the guy asked if it was auto or manuel so it does make a diff but im not sure what.

I've only ever seen that in aftermarket performance ones, never in a 'normal' replacement one. Not sure of any other differences, but I understand you can put a manual one in an automatic, but if you put an automatic one in a manual you won't be able to push-start it.

I remember when I had to replace mine the guy at the parst store ask me if it was an auto or manual and I couldn't understand why that would matter. I want to say they ask me the same question when I bought a new TPS sensor also but I may be mistaken that was a while back.

maybe there's a difference in the input the computer is looking for a9p auto comp vs a9l manual comp??

The manual TFI is made to do push starts. It changes the dwell when it senses the engine is being turned over very slowly.
