Wired everything. This is what I came up with. I do not think I have it right!
It appears that everything is hooked up correctly.

I've been looking into using a Raspberry Pi running tuner studio too. I found this and it looked interesting http://pidash.webs.com/buy-now . I could piece the parts together and just buy the operating system, but haven't decided which way to go yet. I just want it for a cheap tuner studio interface rather than dragging a laptop along in the car.I'm sure altering the files is just another skill to learn but never having done it makes it seem daunting.
Maybe I will have to look into it further a member here is trying to use a raspberry cpu to talk with the ms2 over can that will display sensor information onto a 7"lcd display that runs tuner studio for his instrument cluster.
I wish Matt would make an account here.
Guys, I know I'm not MS, but...

Guys, I know I'm not MS, but this is the best tuning thing going that I know of on SN. I just wanted to jump in and ask what you think about these timing tables
Thanks for the pictures. I just compared mine and the timing seem to be about the same as you, but the AFR table you went richer quicker than I did. I adjusted mine and will see how it reacts.Picture time
My afr table on my current build with 10psi on 93octane. this timing table is my normal tune with no Wmeth, I use table switching to add 6* while the meth is spraying. I could probably add more with the meth but I want it to stay together. %baro is the same scale as KPA
Ok I should have checked the input voltage then. You did have something on the o2 input for voltage but I assume it was nothing.
Btw yes you need to wire the wideband into the MS otherwise I can't help much... I need to be able to see how the engine is doing that is my main tuning weapon.
FYI @twohawks777@cox , wire the blue wideband wire to pin 21 on the optional input (26 pin) and run the black wideband wire to a sensor ground like Pin 22. These Autometers aren't set up in TS so you create a linear calibration in the "Calibrate AFR" dialog where 0v = Min AFR and 4v = max AFR. You can set the min and max on the wideband itself to something like 10 & 18 for a standard resolution (0.5 volts per AFR point), in which case 0v=10 and 4v=18. This is how I have both of mine set.
When you do this, you should see the exact same numbers on your Tunerstudio Dashboard gauge that you do on the Autometer gauge. Also I think it's safe to unplug the factory narrowband sensors if they're installed.
Help...... LOL
Yes. 9.2-9.3 ish.15psi on 91 octane means you better have a lower compression engine built for boost, which I assume your 363 is.
Ah! Gotcha. Thanks!where the car doesn't need ignition advance and isn't trying to make power.
I would have to add some feedback to your idle section of the timing table. You need to have a 4-6 cell section that has the same timing values or you will have the normal idle surge issue.
In the cruise area of the tune (80kpa down and 1800rpm to 2800) you may need more advance depending on your AFR there, I run a 15.5 AFR in those areas. to stop misfire issues I found 43* of timing was needed. The misfire will be felt as small surges on the highway.
Under cruise conditions the leaner the fuel mix the more timing you need to light it off.
Tuning cruise is the opposite of idle you want to make less power so the throttle is held open farther to keep the car at the same rpm. Leaning the mix and adding timing will do this, it's counter intuitive but you want LESS vacuum running down the road to minimize pumping losses.
The boost curve looks conservative I use something similar in my base tunes
Help...... LOL
I believe so, however most wb come with a pre-scaled output. It should be in the documentation that came with the wb.Question. When you say "
Then go into your wideband and make sure the Min AFR is 10 and Max AFR is 18 to match these settings." Are you referring to a setting actually physically on the meter itself?

Thanks.Figured it out. Everything is set I believe.I did another 10 minute run in idle this morning
Hey everyone, I posted previously about a stumbling issue/lean spike I'm having at low load and cruising around 2500rpm. I've upped the VE value in the area where the issue arises and it seems to have helped but the stumbling is still barely there without showing a lean spike.
I'll attach a drive log and my tune. Just want see what you all think and if you have any input on my tune. Engine is a 9:1 compression 306, GT40P heads, TFS stage 1 cam.
Thanks!
