Ecutek you need a cloned ECU to work. BM3 and MHD can just be Femto unlocked without a clone
When you're a few custom maps in with the jb4 and too deep to pull out lol. If I could do it all over again, I'd prob go down the unlock route and call it a day and not bother with the jb4 but like someone said, different strokes for different ppl. Jesse is GREAT and his sauce is bomb though.
This is the route I’m going. I don’t see the need for a clone if I’m going port injection and bigger turbo etc. etc.
With BM3, either flash back to stock or if he is using an OTS flash, flash the Multimap version and he can flip to stock tune with the steering wheel controls on the fly.Mine was an even swap for my OEM cat from the guy I bought my catless dp.
I didn’t want to mess with it honestly. Then come to find out you can customize it and turn it off and on. Hence going back to baseline at the click of a button. Maybe you can do that with BM3 or MHD as well? But… I do know a two guys that got unlocked, got some “tuning” and can’t get back to baseline now. They want to track after doing those power mods.
So being said in my unusual case. I can set it to Map 6 custom tune in town and she’s another car completely. Insanely fast. On track driving hundreds of miles full throttle, I can turn it off and no codes or limp mode.
Which bears the question, do y’all know who my buddy could ask or see to get his 2020 back to baseline with an unlocked BM3 tune? He’s been to lots of places and they keep trying to work backwards and find the problem of overheating (limp mode on track). To me the problem is simple. Turn it all off because we can all drive on track w/out any tune. Is it that simple? Thanks!
