So why not edit your original post and remove some confusion?

in my case by redline i have 10.8 -11.2 afrs this is with an off the shelfmap from the vishnu site.
so maybe its true to have afrs at 11.0 just to be safe.
so we always have to tune afr's by redline?? and not when full boost ocurrs??

 

Here are some of mine taken by a wideband at the downpipe. This one is for 91 octane



And this one is for 100 octane



I wish I can afford to run on 100 octane all of the time. Right now I am running on 93 octane by mixing 3.5 gallons of 100 and 10 gallons of 91. It is only $10 more expensive than filling 91 octane only. The EVOI is supposed to run on 93 octane. The car feels much better on 93 than 91.

 

OK
I just looked at Shiv's wideband cal in the smart install sticky,
correct me if I'm wrong, he says the xede reads 0-5v from wideband as 0-100%
which is AN1 input signal on the xede data display, so if I do a medium pull, just roll on the throttle, in 3rd and AN1 reads 30% or 1.5v, then does that mean my AFR is 13.0, that doesnt seem right. Im using 0+ v330 non smart basic map with no adjustments to fuel or timing.

 

very nice

 

You tune for the entire power badsn and you try to stay as close as 11:1 as possible on 91 octane gas. By redline you taper the AFR to 10.9-10.8. Here is another one of my logs showing boost as well as AFR. Even at boost peak the AFR is as close to 11 as possible.

 

I was just wondering what you are using for logging. I just saw the innovate DL-32 on their website, and it looks pretty sweet. just wondering if you have that, or something else. I love those logs. the xede doesnt have a good logging system

 

The only way you will know is with a wideband. For the record almost all of the downloaded maps have my car running very lean.

I have a C2 autometer af ratio guage w/ the LC-1 wideband that came with my smart system, I'm using the second analog out of the wideband for the autometer guage input, it looks pretty linear and Ive officially used equipment from work to calibrate the C2 A/F meter unfortunately the guage has no digital readout but it seems to track well with the voltage input I induced.

have you heard anyone using one of these or similar devices to help tune (roughly conservitive)

Starting to get on board with more advanced logging systems
my laptop seems to be the weak link

I appreciate everyones input

I used the LM-1 a few times.....its best to just download the logging software from innovate and record the actual AFR on the laptop.

 

Normally the SMART system comes with the LC-1, not the LM-1. LM-1 = big box with built-in display...

I had the LC-1 with smart and a couple friends have the LM-1. I definately prefer the LM-1 but still log with the laptop so you can get the graphs and such.

If you are using the LM1 what AFR's are you pulling?

 

I like to run for pump gas 11.3 tapering to 11.0 at redline for street tune, for meth street tune 11.6 tapering to 11.3 at redline. For track days I typically lean them out a little more...

 

I'm running the following AFR's:
11.57 @3730 rpms w/ 20.65 PSI of boost,
11.26@ 5130 RPMs w/20.13 PSI of boost
11.42@ 6220 RPMs w/18.92 PST of boost
My car still seems to be running rich though.
