[QUOTE="DCguy, post: 16691805, member: 196849"] This vid should give you a decent idea of what it takes to get the software going and first start up / idle tuning.......beyond that you don't want to F around unless you know what you're doing. Take it to a tuner that knows what they're doing and knows MS3. Get a good base tune. The Pro version of the software also has a "self-tuning" feature that will adjust the tune in real time as you're driving the car if you're in closed loop and running an AFR gauge and trying to maintain a listed AFR ratio....this is a really cool feature that will get the VE (fuel) tables cleaned up for you. However, important to note that this feature does NOT self adjust timing tables...this is where a good tuner will do some work for you. [MEDIA=youtube]cpxQ3qEg9wE[/MEDIA] The 2003/2004 cobra PNP MS3 comes with a base tune already loaded so you basically just have to input your injector info, verify timing, and it should idle fairly decent. The base tune is set up for Speed Density (for simplicity) so you can unplug your MAF for the initial start(s) - you'll run a boost/vac source straight to the MS3 so it can manage this. Beyond this its up to you if you want to continue running on Speed Density or switch over to MAF calculation which will require you to input a transfer curve specific to the MAF you're using....the PRO-M slot style works really well and comes with a 30pt transfer curve included...
