ESS stage 1 flash tune review on my 650xi coupe

[dk79]

i cant be happier with the results of ess tuning stage 1 flash tune. the results are amazing. i have tried jb plus, racechip ultimate, ess etronic box and was not happy with any of them.

my car is 2013 650xi coupe.

my stock times by vbox and g-timer were 0 to 60 4.3 sec and 1/4 12.8 at 106 mph.

i sold my vbox to a member here last week because after calibration my g timer was as accurate as vbox on multiple runs so did not need it.

the posted times are on g timer coz i sold my vbox last week.

0 to 60 3.4 sec
1/4 mile 11.8 sec at 117mph
0 to 100 8.5 sec

and all this is on flash tuned car, otherwise everything stock. runs were done today in the afternoon, 80 degree heat and humid and i am 1500m meter above sea level.

another cool thing is that ess gives you OBD cable to change back to stock and tune and for future tune updates which can be done at home with laptop.
they update software twice a year. no no need to send in ecu no m-boot kinda thing needed.


flash tune is 1345+295 for obd cable.
first time you have to send dme in for flash after that everything can be done at home via laptop and obd cable. you can go back to stock when taking car in for service. it takes 10 mins to change from tune to stock to tune.

ess quotes 570hp and 580tq crank numbers.

also the throttle response is amazing, no jerking or sudden/ abrupt surge.
feels linear and power is all the way to the redline no fall off as noted with piggybacks.

Forgot DA correction, altitude 1500, temp 83 f , pressure 30,
Humidity 52. Da correction 3300.
DA corrected time 0 to 60 3.3sec 1/4 mile in 11.6 sec at 119 mph.

Very impressive indeed. I had the BMS Stage 1 on my car and took it off after a week since I felt ZERO improvement in power (which was supposed to be REALLY noticeable immediately). Apparently it doesn't work on all N63tu engines, and mine was one of the lucky engines that didn't adapt to the plug n play tune.

I think when my factory warranty runs out, I'll try this out too!

Have you run into any problems during your ownership?

Man, I love it!. I have a 650i non-TU. My stage 1 put me a 440whp and 515wtq

Hey OP your numbers are great! I have the same year and model and recently bought this tune because of your numbers. With that being said. You said everything was stock and mine is too though the car definitely feels faster and more powerful it doesn’t feel like the numbers that you have. Ik I have to dyno to see my car numbers but I’ve seen ppl with this same 550hp and 560tq flash tune from Ess (those are the numbers they gave me via email) but I’ve seen ppl walk off on the 6.3l cl63 amg and I’ve actually driven that car and that car is far from a slouch. I say that to say from what I’m feeling from just the few runs I’ve done it doesn’t seem like it’ll even beat the cl63 amg let alone walk off on it like if seen other. But of course they could be lying about their numbers or those numbers could’ve easily been whp. Just wanted to get your feedback on should I try new spark plugs another oil change, Air filter?
