SAFC Street-Tuning with LM-1/RPM

[BlazedGlory]

I just installed my Innovate LM-1 with the RPM-converter. First of all, the RPM seems to be logging double my actual rpm, but when I try and program it, it tries to re-program the rpm converter at the same time, but obviously the cable isn't hooked up because I'm using a desktop - do I have to have a laptop to program it correctly?

The real reason though is about the tuning. I've done a little searching, but I can't find a real good thread that tells me everything I really need to know.

I'm not sure what a/f ratios are optimum for idle, no throttle, cruising throttle, etc. At WOT the car holds pretty steady around the low 10s, and even drops down to like 9.9 or 9.8 afr! I think I want my WOT afr to be around 11.5 or so, correct?

Before I go any further, let's check my basic air/fuel ratio knowledge. The higher the number, the leaner the mixture. My SAFC-II manual tells me that if you alter the correction values, the fuel percentage should directly correspond to that number. For example, if you increase the correction by +10, the fuel should increase about 10 percent. Is this correct?

So I dropped all the values on the high throttle map by like 1 or 2 and gave it a little run again. It seems that the afr stayed pretty much the same or perhaps dropped a little bit more, so I set it back to where it was and decided I'd make sure I'm modifying the numbers in the correct direction before I did anything else.

With the car running as rich as it is (around 10.1 afr avg), am I going to need to subtract the values by like 10 percent or more before I actually see any change?

Thanks in advance - Sorry for the silly questions I just want to make sure I have a basic knowledge of what I'm doing before I overdo it and destroy my engine =P
