Dinan

So I got Dinan installed and must say it really brings the 550 to life... however I keep Reading the crank numbers above 600? Is that with all of Dinan mods like exhaust etc?

The Dinan S1 is rated at 590HP. On the press cars prior to release it was 600HP+, but they retuned to 590 HP. Those numbers are for a stock M550 with only the S1. The other items will not effect HP much according to Dinan.

Just ordered and looking forward to getting it installed at my dealer.

Got the Dinan S1 installed. The app is pretty lame and not very user friendly. Not clear what mode (B or S1) you are in. When I select S1, I get a message "no mode was selected", which I assume means I am in S1.

But...it does bring the car even more alive in my brief drive back from dealer. It appears to rev longer before shifts and definitely can be felt. More after I have some more seat time, I can share the changes.

Do you need the app to have the tune function?

Not sure, but I doubt it if you just want to leave it in tuned mode. The app offers nothing else, so if leaving on tuned, he app is not going to be used.

My dealer mentioned they have been having problems with CELs on the Dinan tunes they have installed on the G30 550. Anyone out there actually have the S1 tune, exhaust and springs?

Can you comment on CEL?

Also, how does the car ride with the lowering springs? I don't have the M Handling package on my car.

I have the S1 tune installed on my 2018 M550iX. Zero issues and no CEL's. Was installed by my dealer about 4 weeks ago.

I just want to state for accuracy, if you just have the Dinan tune, it is not S1, it is Stage 1.

I know it's semantics but Dinan S1 is a package that includes the Stage 1 tune, Dinan exhaust and a couple other things.
