The Diagnostic pics are from Monday on setting F.
I am waiting from my friend who has same car but has Dinan to open the 2 apps when he gets in his car.
Btw this just an example as your cars would be faster than my X3 28i

what I'm saying is that it would be nice if you could unplug the box and see what the hp readings are for the exactly same car stock

I have the JB N55 S1 and get slight delay on throttle response.
Also boost seems highest at throttle half to 3/4qtrs instead of to the floor

How is this new RC in regard to throttle response Re delay and boost settings?
Is it same as standard just much better? Is so it's a winner!

Really keen to find this out from those who have installed it?

Thanks

Also vv keen to see dyno. Espec compared to afe / jb 1 and 4...

I was never impressed with the JB4's ability to offer crisp throttle response and it gave me heaps of issues ... surging all the time and crazy weird throttle issues.... So i removed it ! On WOT full power the JB4 was amazing but thats about it !! The RC offers crisp clean smooth power delivery , and as a daily driver its what I demand and want !!

Its only been installed for a day but I already know Im in love !!

Just my 10c worth.

Great, will be v interested to hear more details about it as you drive and 'wear' it in ...

[Guyhim1]

Finally got mine today. its too dark to install it now. i will do it first thing in the morning and then test drive it. came with with a B1 map. anyone know how HP can be expected roughly of course with B1 and a intake?

[M2-BM35i]

Racechip have a long history and reputation. Not sure you did any looking into this before posting you reply?

I guess I didn't stomp it as hard ^^^
- Second one is RC on setting F showing 321/399tq

But both show 21psi there

These are just an estimate and I'm still not done with the advance settings of the X3.

The 2 Diagnostics pics the car was cold started on Monday morning on setting F (snow day 16F) 14.5 PSI barometer and Intake MAP 13.92psi

were you able to get readings on the same car with box unplugged (stock) ?

As far as I understand, default B1 setting will give you their default numbers. The gains with aftermarket intake, you'll need to take it to the dyno I think, or look up on the manufacturer's site which gains do they offer.

Either way, for sure you'll notice a big change just with the B1 setting, which I suggest you test for a while before jumping to higher settings.

I found the AC Schnitzer, http://www.ac-schnitzer.de/fileadmin...t_englisch.pdf article a good read. My take away is that you can get great performance from a 2 sensor system for nearly 1/4 the cost of the higher end systems.

Good performance for less cost, but seems dubious in terms of overall safety for the engine. Although its encouraging to see Racechip runs the lowest boost out of the systems tested, the article seems to question its ability to preserve the engine protection failsafes as with the higher end multi sensor set ups.

Plus with regards to detection and warranty issues:

"Three of the six suppliers admittedly had warranty cover up their sleeve, but would greatly prefer the box to be removed before service work in order to maintain any possible claims against BMW. To put it more clearly: RaceChip, Speedbuster and Ecochip24 are deliberately suggesting their customers cheat! Risky, because the rumour that extra boxes can't be detected after removal is still one of the more audacious fairy tales. In typical damage instances, the manufacturers drill deep and extract all data which many tuners simply cannot see. Exclusive Trading is almost an exception here: for 359 Euro, no- one seriously expects any form of approval or warranty. The situation is worse when it comes to TUV, because in this case only AC Schnitzer can offer this."

Chances are things will be fine, but there is a reason some of the products cost more.

Thanks for chiming in !! Stage 1 Dinan is crapola.... I would rather put a pizza box under the bonnet with better results !! Stage 2 might be worth a look coupled with there intake if they ever pull there finger out and actually deliver a piggyback tuning box that works !!

BMS products as I have openly said on countless occasions , offer great results but man they have a plethora of issues when it comes to throttle control response and the like !

Ya, just so you know the Dinan stage 1 uses the same kind of technology of just increasing the boost through the tmap and map sensors.... it's not like the older flashes where they actually flashed the ECU... Dinan stage 1 for the N55 is just another piggyback.... and not a very good one from what I heard

only in the past few months some tuners have been able to crack the Bosch ECU and started doing flashes....

[chaddy74]

Yeah Im really keen to look at the flash tunes !! But Im yet to see any really solid reviews or feedback based on the outcomes of a flash tune on the N55 platform. One of my trusted sources in Germany played around with flash tunes for weeks ..... and the outcomes were not very good !! Hopefully we will see something soon i guess .

Interesting... I would like to know how exactly works, I understand that is used to increase acceleration but, how big (estimated numbers) is the change in therms of performance due to this increased accelaretion ?

[chaddy74]

Installed it over the weekend !! Nice piece of Kit !!

10 Min Install !!

[M2-BM35i]

And..... Feedback ? ? ?

[chaddy74]

Its works like the eco,sports and sports plus button on the car standard , for example in sports you push the accelerator pedal less to request a % throttle input ... this enhances that again !! It will not make the car faster but it makes the car feel faster !! The box Has 2 x Eco Modes 2 X sports and 2 x sports sharp !! I run the sports 1 on the RC throttle controller and sports on the car ... anything else is stupid !!
