Looks like a cool kit.  Semi interested as my link is been tuned in 2 weeks.

Hey mate

Unfortunately we wont be ready by then sorry. We are teething a few inconsistent Calibration issues with one ECU we are currently trying. We would like to ensure at least the normally used 3 ECU's used like LINK, Haltech & Motec are all compatible before we go any further.

any issues with these BMW actuators?  I talked to my tuner about this he said they can be shocking bad.

Hey Brent

I could imagine he is talking about the DBW motors that have been in service for 14 - 20 years? As the model they originate from were built from 2000 - 2006, So due to normal wear and tear like any electric motor plus most likely having had a hard life as most BMW M models do, They may reach the end of their life span at some stage.

Personally I've never seen one that's out of order, Even after working for a company in Switzerland called Autotech Und Motorsport Gmbh for 3 years who specialise in hard driven Street and Track application BMW M models.

So my answer is NO they have no issues. 

Kind Regards

Thanks Burn4005 

Sometimes people rush threw the products and don't read the descriptions. To counteract this contact issue we are working on a solution for the oil cooling system also!

We will be getting around to expanding on our Oil Hard Line kits mid year which we will then supply the following in.

( All of the below is NOT included in the Oil Hard Line Kits which are on pre sale already )
2x - 10 Oil Hard Lines ( Pressure Tested & Cleaned Ready To Fit ) They can be chosen in LH or RH configuration! 
3x Chassis Clamps
1x Sandwich Plate With Built In Thermostat 
2x -10 Oil Line Hoses from sandwich plate to Oil Hard Lines ( Pre Made, Tested & Cleaned Ready to fit hoses ) Inc Silicone Sleeve over the hoses.

Oil Filters can also be supplied. 

NOTE :
Our Kit does not include an oil cooler or mounting kit, Customer or Shop must fit an oil cooler or adapt the existing oil cooler.

In most cases HKS Greddy etc used -12 Hoses, these must be adapted down to -10AN to then transition onto our Hard Lines.

 

We won't be doing full Oil Cooler Mounting kits or anything like that soon. as that is another huge task and with the amount of bumpers etc avaiable its a fairly big job.  
 

Kind Regards 
Stefan

Poor DBW output tuning makes this far more of an issue than a mechanical fault with the gear itself. you should be limiting the half bridge duty when approaching open and closed limits to keep the torque down. driving it hard against the stops (usually from excessive integral gain or poor feed-forward mapping) certainly doesn't help.

@Stefan Etter Do you have any logs of commanded throttle position vs actual from an ECU, especially at low openings? I'm interested in the control response of this setup under high vacuum conditions specifically for stable idle control. the E46 M3 engine that had a similar setup used an idle control valve for fine airflow adjustment, but it appears there is no auxillary idle air control in this system.

main observations are from the limited pictures i've seen look like the  linkage gain at low openings appear to be quite high (linkage is tangential to actuator arm at low openings) and significant shaft area due to the 6 throttles have a potential to introduce significant stiction. if you have calculated a linkage gain curve for the assembly that would be interesting to see. this may be incorrect on my part and actually be 1:1 through the whole sweep.

Spot on.

So moral of the story is, bring your vehicles to a shop who is experienced with DBW systems.

Thanks @burn4005.

    • Stock ECU (or more accurately stock tune) absolutely refuses to go over 10psi and behaves like you have seen. The Nistune is the same if it is the stock tune. If the Nistune chip has been tuned, the resulting tune could be literally anything for any combination of parts. The Nistune just makes the stock ECU Tunable.
    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way.
