    Is this and/or other shift bog changes in the BMS backend flashes at all?

    The clutch and gas pedal input are at ~300hz, so when PI is cut it happens much faster than the ~10hz sampling of the fuel-enrichment parameter in the log. You are also looking at an end point in the log where RPM=0 (autologging cut-off). Uncheck "view WOT only" for logging and evaluating situations close to the end point like when letting off the gas.

    mal97 replied to a thread HPFP general question in N54
    Increasing the injector feed lines would only do you any good if there was a significant pressure drop from the rail measurement to the injectors. And then when you look at the success VPG has had with their parallel HPFP system, I would not think that the rail nor the tubes towards the injectors are the bottleneck in this system. Deceiving the high pressure rail sensor could work, or it could introduce fluctuations to the fuel pressure. This would have the fuel control valve adjust the pump deliver more displacement to increase the pressure, I'm not sure how this would affect the DME's pressure regulating though. You might simply end up with a rail pressure that is 20 bar above what the DME targets in all or most situations.

    This is correct, as LPFP's usually function different, as they basically act as fan "blowing" the fuel, and thus are sensitive to pressure on the outlet port. The diagram you linked show the typical fuel delivery characteristics according to the pressure resistance (often referred to as pumping height) on the outlet. If the pump has to pump fuel to a higher pressure, its flow will decrease. The HPFP on the other hand is very similar to an axial piston pump in hydraulics, with fixed displacement. This means that if you somehow could lock both its internal relief valve and the fuel control valve the pump would deliver its full displacement or flow, basically untill something breaks. Be it membranes or housing. The pump varies its fuel displacement, and thus the pressure, by allowing some of the high pressure fuel to bypass back to the suction side of the membranes. This is done by the fuel control valve. I am still trying to figure out what type of hydraulic valve the fuel control valve is. I understand its a proportional 3-way cartridge, and pretty certain it is a flow controller and not pressure based. Something similar to these: http://www.sunhydraulics.com/model/FMDB http://www.boschrexroth.com/ics/Vornavigation/Vornavi.cfm?Language=EN&VHist=p537397,p537710&PageID=p549372 I'm still waiting for my own HPFP to die out so I can dissect it.

    HGK Racing is serious about drifting and what they did to this 2-Series confirms that. What will get your attention first is the custom carbon/kevlar body work. It is not necessarily the prettiest BMW widebody you will ever see but it's just designed to be light and house wide rims as this is a drift car after all. The amount of work that went into this vehicle certainly is impressive even if BimmerBoost does not necessarily like the result. Under the hood is a GM LS based motor built by Mast Motorsports. It gets LS7 heads, forged internals, titanium valves, etc. The works essentially which results in 820 horsepower and 663 lb-ft of torque. Naturally aspirated power mind you. The F22 chassis (some are referring to this as an F87 M2 but it's an F22) is bare welded after being stripped down. The body panels were all removed. The interior was stripped and a roll cage put in. A fuel cell system takes up the trunk space. Nitron 3-way adjustable coilovers were installed. HGK machines the camber plates and various other suspension pieces. The suspension arms, knuckles, and other components come from Wisefab. What about the wheels, tires, and brakes? Yes, important components in a drift vehicle. Wilwood 6-piston calipers are up front along with 11.75 inch rotors. In back, 4-piston calipers and 12-inch discs. The wheels are 18x8.5f and 18x10r with 235mm and 265mm rubber respectively. Is this an impressive amount of work? Yes. Is it a great BMW build? No. They threw out the BMW motor, stuck in an LS V8 (yawn), and made a custom body kit that while being very functional in helping lower the weight to 26XX pounds is wasted on a drift toy and not a real roadcourse competition car. People will swoon and drool over this and it certainly is worthy of attention (is anyone surprised this car is headed to Qatar?) but let us know when someone actually takes an M2, lightens it significantly, and modifies the N55B30T0 engine it comes with from the factory to make for a serious BMW track beast.

    Here is a couple of screenshots where the backfire happens You can clearly see that the pi is still flowing fuel even though the foot is of the throttle and the clutch is engaged, this is using the bms controller If your using nls this doesn't happen, but this is too rough on the gearbox so don't want to use it and have blown my gearbox because of it.

    The Lamborghini Aventador SV is no joke capable of running mid 10's at close to 135 miles per hour in the 1/4 mile. However, it does weigh 3900 pounds and the 6.5 liter naturally aspirated V12 while very powerful at 740 horsepower is naturally aspirated and is not easy to tune. The AMG GT S with its M178 twin turbo 4.0 liter V8 on the other hand is very easy to tune. Not only is it lighter than the Lamborghini it has a dual clutch transmission and a rear wheel drive layout meaning lower drivetrain losses and very quick shifting. Keep in mind the Aventador Superveloce is a track car first and foremost. It will generate considerably more drag at speed than the AMG GT S due to its aerodynamics. You take an AMG GT S and upgrade the turbochargers as GAD Motors did and it is no surprise this is what happens on the highway between the two:

    there are PLENTY of unlocked MAPS floating around. Not sure what they do, as i've never looked. But they are out there. And the stock BINS are there as well. I'm personally not going to be providing any unlocked maps aside from a Valet since i've had several people ask me for it for some reason. On another note, I8A0S, IJE0S, and IKM0S definition files are complete for this software package. working on INA0S now, should be done later today or tomorrow sometime.

    Got a chance to grab a screenshot. I changed a couple more things than everyone else. But its been working great since the change.. Was 100 degrees outside yesterday with some decent humidity. And the oil temps still hover around what my original pic was. Screenshot of my settings: EDIT: actually have a client about to run an Autocross event right now on the above settings. So he can let me know how these do in a racing environment shortly.
