Engine Drivetrain 1st Gen Cooper S Most liked posts in thread: Mynes/ByteTroniK Remote tuning

It has been some time since I have updated the going-ons with my Remote Tune from Mynes / ByteTroniK.

The tune has been complete for sometime now. I would say about 1500 miles have passed as my R53 is not my daily car. Lots of miles were racked up at this years MOTD and was an easy way to gauge improvements as I have been back to back for 5 years in the same car.

My AFR is still on the money both cruising and WOT, the Bosch 550s keep up with everything inside and out of the engine with very low injector duty cycles. This leaves me lots of room for a larger valve head and cam, or what ever I choose to do.

No running issues, no flat spots, great individual cylinder values. Spark plugs look great and even across the cylinders if you look for that kind of thing like the old school guys do at times.

Heck they guys took the time to touch up my tune long after it was completed due to me changing out a cat pipe. Every update was within 24 hours of me sending in logs via email and every question answered no matter how minor, even some fun back and forth about nothing car related .

The engine was fantastic in the Mountains of North Carolina. The torque and mid-range improvements made for a bit less shifting up the mountain and the DCS improvements / adjustments kept the tires to the pavement without limiting speed.

I cant say enough good things. My experience has been fantastic with Mike, George, and Jay and they will have my business for as long as they let me .

I would also like to thank everyone for keeping the thread civil. I know everyone likes to defend their opinions and desires and that is a healthy thing! Everyone has their brand be it soda, beer, or tuners .

 

It does all that .

But in reality just the throttle response is so much better. It honestly tempts me to hit up a local dyno just to see a number. However with no baseline before the tune, or any baseline of my particular R53 then what is the point right? long as I am happy with the results its all good to me.

 

Temps are not going to be any different with a tune unless you change the fan setting maybe. Your not adding more boost. Oil pressures are regulated in the pump and filter housing no electronically so no increase from that. Actual cylinder temps could be higher or lower depending on the fueling I guess.

In many ways a good tune can increase the life of the engine. But your right foot my decrease it .

I could add that I use a pair of innovate oil pressure and temp gauges for monitoring, modded the oil filter housing for the pressure and temp sensors.

 

Thanks for the good questions Jason. Those kind of questions get answers out to those who are thinking the same.

 

Just to update this thread. I received an updated tune recently with some exciting additions.

I have a Pre-facelift R53 with a Facelift Gearbox / LSD. So my cruise would not work as the DME can not recognize the gear selection. They were able to make the alterations to allow the DME to see the new gearing. This resulted in easier logging files as well as more burble that we all love .

Also had some DSC additions but I am still learning those changes.

Happy Camper here

 

Title fail

 

Honestly I have no idea on the fuel consumption. After I went down to the 15" wheels with 205/50 tires the revs on the highway are much higher at speed so that hurt fuel consumption about 4mpg all around! Lucky for me I dont drive highway much I guess .

No faults were tossed at all. I installed a Schrick cam just before the tune and have not seen any faults at all. The tunes can be reversed with this system as one of the steps is to save your stock tune on your own laptop to revert back to if you wish. You can even do multiple tunes for other fuels and such.

Another question was asked how you can check your engines health before moving forward.

"Multiple things can be done. You can pull and read the spark plugs for potential cylinder to cylinder issues, You can do a compression check, You can do a leak down test, monitor oil consumption over a given range, smoke the intake system for leaks. If you are close to a BMW or MINI service center with DME monitoring software you can have the cylinder to cylinder true running values read, or they can can check the current stored additive and multiplicative fuel values (This is part of the adaptations people strive to reset)."

 

Thank you good sir. My R53 could always have more mods (Big Valve Head, more aggressive cam, ect), but I am happy with the current mods.

 

Thank you so very much!

 

Thanks Mike. I got some great stuff from you as well
