So when I bought the car it already had the dinan stage 2 flash on it and its great but I want to get a little more power along with the other things that a jb4 can do such as clear codes etc. im just wondering if this would even work or if it would be bad for my car. tried searching but couldnt find anyone who has done this yet.

i believe the jb4 will just ignore the dinan and run as usual but im not 100%

doesnt the jb4 have to run off of the stock software though and then modify that or does it run its own software through the dme

I believe Map 6 is for those with the 335IS, 1M, or Dinan tunes but I may be wrong

I have read others have stacked a JB+ over a Dinan flash but if you are still under the warranty and it becomes detected they will void you. If no warranty concerns then go for it. No idea if the JB4 works but a call and you will be enlightened.

once you put it in the JB4, connect it to a laptop and in the JB4 software choose from the drop down menu the flash settings

[Mike@N54Tuning.com]

With the JB5 G5 ISO you just run the same settings as a 335is along with map 2 on top of Dinan. Use map 0 for your Dinan tuning and then map 2 for the JB4 performance tuning.

my car had a dinan stg 2 flash when I bought it and I had jb4 g4 at the time and for some reason it didnt work well together i had target boost issues and inconsisitant to say the least, as soon as I flashed back to stock car ran fine, plus it is great to see the service writers face when you tell them to get the dinan shit off your car

did you mean jb4 or is there a jb5 coming out? I guess i could always just try it and take some logs and if there are any problems flash the car back to stock, also wouldnt running the same settings as a 335is be for an n55 only? my car is an n54

i am still under warranty because the previous owner bought the 100,000 mile warranty but I could just take it out when I go to the dealer because I dont go often at all, would that be a problem or can the dme register that there was a piggy back tune on the car if the dealer were to look at it

100k warranty(wow I'm envious - as in months to come I will have to make a decision to buy one or not, $$$, myself), is something I would never fk with but with that being said, I have never read that BMW has the ability to read the DME for piggy back shadows so you are most likely fine if you remove the unit and clear codes. The only problem is if you get hauled in on the back of some roadside toe and didn't have the time to play Houdini and make it disappear.

haha ya my warranty expires in 2 years anyways so I might wait till then but if i were to get hauled in it wouldnt be to the bmw dealer there is a collision repair center in town that handles almost every higher end car and I know the owners well so I could slip right in and slip out undetected lol for now ill probably stick with a dinan fmic and bmw PE to keep warranty though

JB5 was a typo...

335is is an N54. Since it has its own more sophisticated programming, using the 335is setting in the JB4 software allows the 'is software to do its special stuff, only max boost is taken over by the JB4 when it's targeting higher than DME levels. When the DME is targeting more boost (i.e. overboost and a low-boost JB4 map), the DME wins. Same story with a stacked flash situation (essentially, a flash is just DME programming - the JB doesn't know it's a tune).
