How are your 320d doing so far?

[TorqueTuning]

Think so, it amplifies the magnitude of the injection.

Powerkit : Torque curve flattening and give better rpm range
Vector : Direct increment, especially in the 2500 rpm range, powerkit does not have that effect.

Vector 285-200 ft-lb , Powerkit 255-200 ft-lb ,from 2500-4000rpm

So Vector is quite safe to use, and if you cruise at highway the rpm shall fall on the high torque range. And therefore save fuel...I reckon.

Bro,

I think Powerkit should be 255-175ft-lb from 2500-4000rpm, right? ----> Ignore this... misunderstood

 

[jwah]

No it is 255-200 ft-lb from 2500-4000 rpm, that is why it is more flattened

 

[TorqueTuning]

thanks for sharing. wuk's ride is also another roadwarrior, car-eater!
nice smooth curves overall. however, unless my eyes deceive me, there still appears to be an anomaly at around the 3750rpm mark. any ideas what this might be?
quick question - are all the vector tuned curves approximately the same but with varying fuel input signals to increase the power/torque?

it could be some anomaly at about 3,750RPM but more like a spike as oppose to a power drop. my theory, most probably that will be the highest boost at that point and the turbo diverter valve (waste gate) starts regulating the boost pressure? as for your DTUK, you also tap into boost signal, will that be a reason why there is a drop around that? yes, Vector only alternating the fuel pressure and maintain the boost.

oh..now i know what you are referring to. you are compairing a PowerKitted 320d and Stock 320d+Vector. that is why Vector-ed ride u can feel more 'G' from 2,250RPM onwards.

sorry bro, but i beg to differ with your assessment that the 3750rpm curve deviations are due to the tuning box. do note that the anomalies can be observed in all the stock curves. you can see the same behaviour in my 320d, the 520d and wuk's 320d when dyno-ed on the stock setup. in the heartbreaker dyno, the effect seems to be attenuated out more, which commensurates with the nature of the dyno measurement.

however, you may be onto something with your point on regulation of the boost. we can still observe the anomaly in the vector-ed curve, because the boost is not altered. however, in the DTUK-ed runs, the power/torque deviation can hardly be seen at all in my 320d, but you can observe it somewhat in the 520d curves at the 3750rpm mark. this should equate to a much smoother power/torque delivery at these "high" diesel rpms for DTUK

 

[jwah]

Could it be the gearbox switching the gear...


Yes, and No. Yes if you developed some faults which are registered in the ECU. No if you can run it smoothly and remove it when you see them.

Well. Well see this



and this

 

[Mavik]

Are there any tools for BMW that you can catalog the car while running on the dyno? I have a program for my VW (rosstech vagcom) which I can log all the necessary data points from boost, air intake temp, etc, etc. good for diagnosing and tuning maps for the car.

I think Maniac is right where the dip at 3750rpm is not due to the tuning box. Here is the dyno graph from Mavik's stock 320d using the Vision machine. A dip is also observed.

 

[TorqueTuning]

seem like very true then. Maniac Vision dyno chart does show similar characteristic. must be something to do with the ECU, yeah. BMW limit the power there.

Well, my guess is the DTUK or Vector will modify and overide the existing map. The box modifies the boost sensor readings and causes the fuel flow to the engine increases in a particular patern according to the desired outcome. This is done by increasing the openings of the injector and increasing the fuel pressure in the common rail.
DTUK/Vector may increase the intensity of the map, but still keeping to the original map profile.

By adding DTUK/ Vector to the PPK cars, may just provide minimum increased performance due to the bigger intercooler. If the car has more hardwares ie improved exhaust, air intake etc this may increase the performance alittle bit more. But the fuel flow mapping remains at the modified parameters determined by the DTUK/Vector.

The Pedal Box, however, will change the signal to the ECU, intensifying the signal by looking at the the pedal travel and the rate on how fast it moves. This will result in more responsive car behavior.

So if you want to have more power, go for PPK/DTUK/Vector. If you are lookng for responsiveness, add the Pedal Box...

Diesel engine have soooo much potential, the additional of the electronic devices/ hardwares will definately improve the ride. Just how much you want it to be lah... I personally prefer to have many-many choices so i can change according to my driving mood/traveling requirments, so i picked the one that have most choices to satifies me loh.... If I want power- I select MAX. I want mild-i select to medium. If my parents taking care of my car while i go abroad, I select to minimum loh...........

Just my 2 cents..

Ive also been told by Kingston at Everco that removing the cat will increase horses too ( not sure about torque) , and it would definitely give more sound then what we have right now. Only problem is confirm will have more smoke kau kau, and maybe check light error due to O2 sensor. I was tempted to do this initially, but didn't want to void my warranty, so i decided against it. However, when the time comes ( probably when the cat mati ) i'll relook into that idea in the future.

[kong]

yeah.. my friend's pickup Navara lost power after sometime. Went to workshop and removed the Cat... Power came back!! i suppose its the soot that clogged up the cat and obstruct the exhaust flow.. maybe we should do the same on our 320d.... then many will eat smoke..!!

 

[Mavik]

Kingston would have something to fool the O2 sensor, cost a bit but the best is to change the cat from the stock standard to the high flow sports cat. Well that was the case for VW cars. Usually that comes with a nice downpipe as well

Most stage 2 remaps by tuners usually will remove that CEL for the O2 sensor but since we don't have it, a bit Susah

 

[carlsson]

the custom downpipe and skinless cat would be an interesting next stage, again, when warranty runs out..hahaa..

i heard however theres a 320d owner who cut the cat from his new car and quill more or less void the whole intake system of its warranty. According to my SA, theres a slight burble coming from the exhaust now. But he's still using the droopy pipes..

[rusminag]

Had my first scheduled service on Monday. Felt a bit funny afterwards especially when speeding.
Today noticed that the front hood shaking at high speed. Checked and found out that the hood was not properly locked (driver side hood lock was not secured). No warning from the computer.
Need opinions from all on what action should I take, as the hood may have hit the windshield if it gave away and cause serious accident afterward.

 

[BaddBoyz3]

Why not go back to SC and check?

 

[rusminag]

I have opened the hood and close it properly.
The issue here is negligence by BMW service team.

i would suggest to go back to SC and tell them the incidence. perhaps the hook needs adjustment. if not rectified this time,it may happens again the next time. and this may caught the next unknowing driver by suprise.
Cheers..
