What the f*** is happening with tunerstudio?!?
Connecting my laptop for the first time in a year.
i updated to the current ts version, and then plugged serial to usb into my laptop. doesnt stay connected. What the eff |
It does this engine on or off
|
Now the connectionis magically fine, and i didnt think i made any changes to the tune, but now my car is running 3points leaner. So way too lean.
what is going on? |
Whatever happened i just added fuel back in all over, and got the afrs back in check.
|
I think i had ts set at a different map than what the ecu was running, and it was trying to decide which to display and connect?
not sure. |

If your state has changed to Summer mix gas, AFR's should have gone rich, not lean. |
^no idea. I have been driving this car all along, and this ms3 is possessed.
Literally was at 11.5-11.8 wot at redline, then i connect the laptop, finally comes on line, and poof, its 15.8afr at wot. yikes. I guess 15.8-11.8 is 4, so there is my simple math at it's best. I just added fuel to correct for the possession, and now its a hunky dory 12.9-13:1 wot at redline. I would hazard to guess utah isn't on summer gas yet. it has snowed the past few days, and its in the 30s right now with windchill |
It moves to Summer mix when the EPA tells it to.

Oh ok, then maybe, but i didnt fill up between the two wildly different afrs. I was driving at 11.8, then i plugged the laptop in, and poof 15.8.
I'm only worried it will switch somehow again, but I think it will not switch as long as I don't fiddle with the tune. When I do plug the laptop back in, I'll just have to be careful, and remember to watch the afr gauge and make fuel adjustments if I need to. I'm sure this is just a bandaid, but I sold the potential solution already (another rev built ms3) so I got to work with this one. |
