Default I need some MS help

I'm running a megasquirt 3.0 mainboard nothing fancy, with the high res 10g code. Everything runs okay but I need to be able to tune it again.

It's been a couple years and I bought a new laptop because the old one totally crapped out. The only thing I've downloaded as far as software is tunerstudio and Java. I plugged into the megasquirt and tunerstudio said it doesn't detect the controller or something along those lines. Am I missing some software that I need to download?

I got it going. Apparently it thinks the engine is in boost at idle and running lean. wtf? So I tuned the area the dot should normally be in at idle, cells 40-60 kpa @700-1200rpm and it makes a difference. No changes if i tune where the dot actually is, cells [email protected] wtf is going on here?

I guess it could be a bad map sensor. The line looks good getting -16 vacuum idling on my boost controller that is connected to the same line. But if it was a bad map sensor shouldn't in tune in the cells it thinks it's using?

Downloaded the software package from DIYautotune.com it did something to my TunerStudio and now won't let me use it saying I need beta.

Megatune is working and it's not doing that weird crap with the dot in the wrong cells anymore. Unfortunately It is not letting me edit so the AFR reads in AFR instead of volts using a AEM uego linear wideband. I can't find MTcfg

We need to update that download package - get the latest version from TunerStudio.com for the time being.
