If you have a 2017, bowler makes an add on harness that's a workaround, and that would be the easiest solution.Hello Magnum XL swappers! I'm planning my swap and most likely going to get everything through Modern Driveline. My car currently has a Whipple stage 2 kit on it running on the Whipple tune. I know tuning changes are needed to run the Magnum with the different gear ratios and a few other things.
I have zero complaints about the Whipple tune. Car makes great power and runs awesome. I've been debating what to do in regards to the tune and my question is around HP Tuners. I think I'd be comfortable making the tuning changes myself if someone can steer me in the right direction.
Does anyone here know exactly what needs to be changed if using HP tuners? I'm assuming gear ratios somewhere, but there is also talk about 'shift assist' and making cruise control work. Just trying to avoid having to go with a pricey third party tune. Appreciate any info!
If you're set on making changes in the actual tune, someone else would have to chime in, as you still need a physical harness/adapter to communicate from the trans to the computer, from there, it becomes geek speak.
