Rebellion Bi-Turbo Tune Plug and Play Sale !!
We did Claude's car first. Tuned run then stock run. I'm still waiting for the email with my official number (I think I wrote my email wrong... Claude got his info and forwarded them to me).
TUNED
Peak HP (engine - estimated after measuring Wheel HP and doing a "drag" slowdown in neutral to estimate powertrain loss): 697
Corrected HP (21 degres celcius): 693
Wheel HP: 529
powertrain loss: 168
torque (SAE) 657
STOCK
658
630
475
183
580
Will post my offocial numbers when i get them, but here is what I remember.
My car as more powertrain loss than Claude's.
Tuned
Peak enngine HP 705
Wheel HP 499
Stock
cant remember... was too impressed with 705!!
Of more importance, when driving back to montreal, I left the car stock and really felt a difference. car felt a lot less responsive to throttle impulse and felt slower/less lively.
All in all I'm satisfied with the Rebellion tune and the numbers correlate to announced gains of roughly 60 HP. The fact that it's plug and play and reversible/transferable to another car are ++ for me.
I can imagine how a fully tuned E63 might be!! There are monsters, and the things that scares monsters. It must be in the second category.
Both Kart125 and I had the Tune on our cars for over one month now with no issues.
As shown on the Stock and Tuned dyno graph below, and using the HP and TQ Corrected net numbers shown as P-norm* for HP and M-norm* for Torque the Tune gained 62.9 HP and 76.2 LBF.FT. Rebellion said 60+HP, so they are right.
2015 E63 S AMG
Stock : 629.6 HP and 580.5 LBF.FT
Rebellion Tune : 692.5 HP and 656.7 LBF.FT
My car was running 94 oct gas, but the engine was heat soaked as I had just driven over one hour to get there and the Dyno Operator ran my car for at least 10 min. on the dyno trying to sort out the Mercedes setting for the trans to stay in the right gear for the pull.
Kart's car ran after me, so it ran cooler, showing a bit more uncorrected HP but his heavy winter wheels created more drag showing a bit less corrected #.
Overall we are both very happy with the results for a simple and relativly cheap Tune.
On the Graphs : Red line is HP, Yellow is TQ, Blue is RWHP and Green is Drag loss
Graph show my car only, pic 1 is with Tune, Pic 2 is Stock, and Pic3 Last graph is Stock (slim line) vs Tune (Thick line)
When Kart gets his Graphs from the Dyno, he will posts his.

Did you buy the tuning kit? It should have come with instructions with color pictures. If not shoot a PM to Matt at Rebellion and he will send them to you in PDF format.
If you are just inquiring about how to get to sensor, here is what you will need.
1- a good lighting source. I used a small "petz" type camping light that I was able to position in the back of the engine bay to see the sensor.
The sensor is quite hard to see... it's in the back/driver's side of the engine. You can see it if you get close and look with flashlight. You will recognise the top part of the grey clip that olds the sensor in place.
Also, make sure you plug the sensors in the right direction (sqared end of sensor with squared end of socket). I got the crankshaft sensor upside down the first time and the engine was misfiring quite badly!!
2- a pair of XL long nose plyers, ideally with a 45 degree bend at the tip. Similar to these ones

I got a pair of straight ones since the bent ones were backordered and I was able to do the job just fine
3- it creates more space in the back if you "unclip" the wire older just above the boost sensor. Makes it easier to slide your hand in there. If you have a friend with small hands bring him along...
4-patience and faith in you ability to get the job done!!
5- be vareful with the grey clips on the sensors. they are fragile. practice with one that is easily accessible to understand how to unclip and clip them.
Good luck!

How long would you say it would take from start to finish on a stock car knowing what you know now?

Thank you very much! I was able to do it thank god. It did take about 1 hour for the boost pressure sensor. Wow! For a moment there I thought this is it, I'm not gonna get this done but then I thought to myself if other people have done it so can I. I will tell you what helped me though. There's a loom of wires on a plastic bracket(removed) with 3 zip ties in which it was a must for me to remove so I can see exactly where the sensor connector was. It was easy to remove the connector from sensor and it was easy for me to forget where it was connected.

Now let's test this thing and tell us what you think.
Now put some Renntech mufflers and feel how the car should have come from the factory.
Good question... hand brake was definitly not activated

I was expecting 20-25% but it looks more like 30% on my car. SRT's car was a bit better in that respect. Is it the difference between wagon/sedan? 2014/2015? inherent variability between cars? God only knows...
I keep telling myself that the tune brings the car to what it should have been with less powertrain loss!
