Remap only with 7% more fuel gave me aprox 260hp/600Nm. a gain of aprox 30hp/100nm
And after adding the bigger IC we did a remap again with almost no difference on the dyno. But it gave a big change in the way mid accelerations are done :-)
Glad to hear it :-)

I think you are referring to the injector opening time map.. In reality the throttle request maps are probably requesting 600nm now which is the highest nm the Bosch EDC16CP35 ecu can interporate... more power is gained by adding % to the injector opening time map. In reaility your injected quantity will be significantly higher than 7% :-)

If at WOT your throttle map requests 600nm, the ecu will check the torque limiters are at 600nm... assuming they are the ecu will look up the NM to Injected Qty conversion table shown below.

Therefore injecting more fuel relative to the requested torque...
The injector opening time map is more a secondary... hence 7% more :-)

Well I can only refer to what my tuning guy told me.
We spoke of the problem with smoke after removing the DPF.
And he told me he could control that with the amount of fuel he added. And he then mentioned that he'd only added 7% more with the mapping I was running now.

And I'm sure he knows what he's doing. He's been tunning both Skylines, Supras and Lamborghinis. All petrolcars though....
You are saying that the Bosh ECU can only go as far as to 600nm or?
Ive seen dynos from tuned 330d's reaching aprox 700nm??

When tuned correctly a stock 231hp m57n2 will not make any real smoke until you exceed 285hp. I would expect you could get closer to 300hp with your FMIC.

I have tuned them to over 700nm no problem however.. the maximum requested torque on the 231 version is 600nm therefore you must do a few things...

1. Request 600nm
2. Increase the Mg/stroke in the NM/IQ table pictured above so the engine management thinks it requires to inject more fuel in order to achieve 600nm.
3. Increase the injector opening table in microseconds so that the engine management thinks it requires to open the injecor for longer to achieve a given Mg/stroke.

Thats a very very basic account of how it works... of course there is far more to it than that. :-)

This is very interesting.
I hope for aprox 300hp/700nm and will be satisfied with that(I think :-)).
Often what happens is that the power becomes a habit. And one want's more :-)

My concern is the autotrans. ZF says my version is build to cope with 600nm. Going well over that might be a problem. Speaking to the guys at promotec in South africa who does these 300hp/700nm conversions, they haven't yet had customers who has had any problems with the autobox.

Your car is going to need many hours of dyno time to set the turbo geometry to the downpipe. Whilst this is happening you should advise your tuner to limit the torque to 700nm... you can still comfortably achieve 300hp without hitting this huge torque hike...

You are probably aiming for something like -


You can see here it doesn't take 700nm to make 300hp... in fact you could achieve 300hp without even exceeding 540nm... it takes around 535nm @ 4000rpm to make 300hp :-)

Nice dyno.
It's a bit different than my current setup. I have more torque in lower rpm's
How is that setup on the road?

This is how mine is right now. And it's quite nice with that much torque at the low rpm's

We do offer different versions of our DPF removal downpipes... our sports cat versions have become more popular recently and is actually what I have fitted to my own X5 35D... This makes absolutely sure that there is no odour and looks quite oem... it's more expensive naturally but there is absolutely no compromise on performance with this part.

Will that downpipe fit the X5Diesel in USA

Atiam the 335d and X5d are same engine but I beleive different tubing, correct me on this. BTW contact Lenny @ RENNtech he is also interested since they tune my 335d.

ecotune Im curious the USA 335d is running 268 hp vice the EU version of 286 hp, I have already achieve 300 whp with RENNtech alone!! I believe I will be able to achieve with the WAGNER IC and the downpipe somewhat like 30 to 40 hp gain, does my math add up correct on this

It seems this is not the case in the USA... The X5 35D has the previous generation EDC16CP35 ecu where the 335d's in every USA case I have investigated were only introduced with the EDC17 ecu and all have Urea injection.

DAMN piss tank!!! I spoke to my mechanic he raced my car since I had broken hand for the Puerto Rican 1/2 mile race and he did mention with a FREER exhaust I would be able to at least keep with the GTRs and so on. I firmly beleive the downpipe can be resolved like I did with my old 02 MCS, just GUT OUT the inner liners, trust me my MINI did improve on performance and NEVER got a CODE!! but I doubt this can be also done on the "D's"

Gutting out internals in our experience made for outragous turbocharger deviation. In some cases the tips of the compressor wheel broke off and the turbo was junk. We conculded that as the empty DPF created such a low pressure result... like a plenum chamber the boost could not be controlled.. hence why we developed the downpipe/software..

If someone can get us an original downpipe from USA.... we will make one to the same spec as UK/EU models.

thats true my 02 MCS was supercharged, my bad, If I could get you the downpipe I would send it to you, sheit Im capable of sending mines to you LOL. What do I get in return amigo

question here at ecotune you and RENNtech would have to be in unison to mod the FLASH I already have.

I assume your ECU required to be removed... if so you would need to post your ECU to us for the tweaks... Full DPF removal, Urea and FAP function disabled, Turbo Geometry re'align, EGR delete etc...

Who are RENNtech?

I'm afraid what we can discuss with any other firm, particularly with regards to our software modifications is limited for reasons im sure you'll understand.

I think we would benefit from a representative in the USA though as we are e-mailed regarding this almost every day.

We are of course delighted to assist the end customer though.

Best wishes,

Stan

Stan, what kind of capabilities would be required for a U.S. shop to be able to perform your software mods over here? I am aware of at least one shop that currently cracks open the DDM and also installs software (from Evolve in this case). So the shop is an installer only, not a "writer" or tuner. Renntech does the same thing, but I *think* they write their own code.

If you have a situation in which a car in the U.S. has been modded with your downpipe, along with a more efficient i/c and perhaps even meth injection, is it even possible for you to evaluate the car remotely and change the programming to take advantage of the added capabilities of the car?

Would it be possible for an individual to install the software after the hardware is installed/modified? For example, we have a vendor in the electronics arena that is located in Poland, but he sends out the necessary cabling, and can remotely program the car - this is not simply coding, he has the capability to modify the car's programming (for navigation/audio/etc.) via the owner's local pc.

Just curious if it might be possible to use your capabilities and knowledge over here, since (as you can probably tell) we are behind times on tuning the d.
