Tooling up for MFI tuning ( Recommendations Please)

Bob, you keep threatening to come down. If you actually show up, I'd bet we could get Jeff Higgins to walk you through it.

I bought the LM2 to adjust the AFR on my car. Like it so much I permanently installed it. second most useful gauge in the car. My car runs lean during warm-up (not cold and not hot). installed it in the cigarette lighter so easily pulls out to go in the glove box if ascetics are important.

My used LM-1 should be arriving this week (opted not to get the LM-2 since I wouldn't be using the majority of its features).
Looking forward to checking the system out.

OK, my LM-1 arrived today and now I'm confused about what the best AFR (CO) values will be for idle and part load on my 2.4S. Given that most people feel the CO values in the CMA book are too lean, I've searched the forums a lot and seen:
3-4% CO @ idle and 5-6% CO @ part load
ALSO
5-6% CO @ idle and 7-8% CO @ part load

Any consensus?

Update,

Car is running pretty damb good now. My mechanic friend and I may disagree on how he set up the linkages but the proof is how it is running.
I bought the Synchrometer from Pelican and it worked well. I wish I could say I had more seat time in a good early 911 to compare but I am going to have to leave that to Kenik if he can make it.
