MSD DIS2 Question

[CMiuc12s]

Hey everyone, I have a 1991 GSX and I just installed the MSD DIS 2 box. My question is for those running DIS 2 also. I am able to get rpm readings on the gauge cluster, but when I look at my S-AFC2, I am not getting an rpm reading on it. I know that it is rpm based on its adjustments and now I am worried that with the MSD bow running and no rpm reading on the AFC, will it still make the correct fuel adjustments or not? Will I need to run the tach adapter#8912 from MSD to get it to read on the AFC? Right now I am going to loop the connections until I get a good answer for this. Well I just drove it around the block and my low, mid, and High trims went to 100 across the board. After a mile or so I noticed the low trim go down to 96% and the others at 100%. Car ran fine, maybe alittle smoother, also the staged rev limiter is a nice addition too . But am I still correcting on the AFC?

no one has an answer for this? come on, I am sure that someone else here has had the same problem before and knows how to fit this.

I'd call or email the manufacturer about that. I'm sure they will help you.

I can't answer your question, but hopefully, I can put you in the right direction. I have a 2G and I need the tach adapter, but for the best answer on your setup, head over to this link and download the user's manual on the left side of the screen:

Hope that helps!

Well, my suggestion is buy the adapter it will solve the problem. All DSM with a Dis2 need the adapter that is right from MSD.

Thanks
