US$ 9.100 - 9.600 plus labor.

You could save a lot money by buying cheaper parts or via group buys.

$2000 for a boost and afr gauge that can data log? If you're going to spend that much you might as well just get a standalone with boost solenoid, then you can monitor AND control a whole lot more than just AFR and boost. Then you can use the $1300 you saved since you don't need a procede anymore on dyno time/having someone tune it if you can't and treating me to a delicious steak dinner for the great advice.

Thanks, great to know. Just re-prioritized the importance of the LSD in the 335i.

I wouldn't doubt the LSD's merit so quickly. Although DSC/DTC and an LSD will both help you get going in the rain or snow they are two fundamentally different systems. DTC (active at low speed) applies braking to slipping wheels to transfer power and help you get moving. DSC (active at higher speeds) actually cuts engine power in addition to applying braking on slipping wheels. An LSD on the other hand only keeps power going to both drive wheels (using clutch plates, viscous fluid, etc) so you don't sit there spinning one tire that's getting 100% of the power. In other words DSC/DTC is a reactive system that sees you're losing traction and slows you down, an LSD simply ensures you are using all of the traction available thus speeding you up.

Hi

Thank you for feedback. The dalalogging system is capable to log 32 channels and contains of different parts. I currenty plan to log 8 channels:

2 x XD-16 ( DX-16-1 & DX-16-2)

XD-16-1 Boost Gauge
XD-16-2 AFR Gauge

DL-32 ( DL-32-1)

MAP BOOST
CH1 RPM
CH2 TCInp programming
CH3 Ignition Advance
CH4 Road Speed
CH5 Accleration
TCInp EGT

TC-4 ( TC-4-1)

TCInp1 IAT

LC1 ( LC-1-1)

LC1 AFR

Sensors are included in the price. I want to know what's going on with the engine.

Thank you for your LSD information, it is very helpful.

Cheers
Eugen

In Lsd the wheel with more grip is braking the otherwise spinning wheel down. Dtc and electronics is no worse in braking the spinning wheel than lsd. Both allow a limited slip. In both cases the friction between the tires and the road is the same. What makes you to say lsd has more traction?

I would rather put the hundred or two towards the gauge just to make sure, its not breaking the bank in the grand scheme of things, but that's just me.

I don't think the boost will be dependent on temperature (Oxygen is). The current maps are rather lame. I use 94.5 oct, so there is a lot (read too much) of safety margin so far. If taken to a limit by aggressive map, I would not rely on gauges. It is hard to react fast enough. You need to have a microphone in the engine bay and speaker in the car to listen for the detonation if you want to react fast enough Gauges are just nice to have (except I want my 335 to look stock i.e no gauges).
I have a first class extremely accurate industrial boost gauge in my Lancia. Shows also negative boost, is well dampened and looks functional Less than $20.

Datalogging is a nice hobby for an enthusiast and useful if trying to find out the last 2 hp and extracting them safely by finetuning the map. I have a full confidence on Shiv and other commercial providers for them offering maps that have enough safety margin without any need to worry about the detonation.

Ok fair enough, but I still feel that a boost gauge is nice to make sure that things are working properly under the hood (ie. a sticky wastegate or anything like that which can cause you to overboost or a boost leak that can cause you to bleed off boost and your tuner's ability really has nothing to do with), and not just a luxury. I guess everyone has a different view point though.

The simple answer is the reason why you turn off DTC/DSC to drag race: braking is counterintuitive to accelerating. An LSD simply ensures power is going to the wheel(s) with traction.

I agree, if something is wrong boost gauge may help to diagnose the problem. Makes sense especially in my 18 years old car... I might not call it a "performance" mod, though. Its useful and makes no harm if one is ok with how the additional gauge might look.

Lsd is in effect braking the wheel, which would be spinning. That is the reason for no wheelspin. You make it sound like lsd would put more power on that wheel too, but it is vice versa.
Both systems ensure power is going to the wheel with traction. If both wheels have traction, neither system is working.

If you turn off both dsc and dtc you do not believe in lsd as dtc simulates lsd perfectly.

Braking the spinning wheel a little increases the coefficient of friction and thus increases the acceleration. Power keeps going to the wheel all the time.

Having LSD you can end up spinning both wheels. Advantage for DTC.

A 1000hp M3 is a nice showcar, but I did not want to spoil AA's thread by saying that IMO, for a street car, it is plain stupid.

The original M3 has never been designed to be a 1000hp street car. Most components must be stressed well over their design limits.

Cars must be balanced. Increase in HP/TQ must see equal increase in brakes, tires, suspension, drivetrain etc.

Not so long ago I spent an afternoon with a Ferrari F430F1 on the road above Monaco. I am sure this car costs much less than AA's 1000hp M3 but is probably much faster on those roads as it is extremely well packaged together.

Uhhh... I would tend to think that although the Vic's M3 has a lot of money put into it, the Ferrari is still significantly more expensive. How much could a built bottom end and turbo setup really cost? No way its more then 25k, and you can figure if he put the same into the rest of the car, its still a lot cheaper. I realize what you are saying though about having a balanced car, I would still take the F430 in a heart beat over it, but in a manual. I don't think you can get an F430 for less then 200k though, I think they are still marked up over MSRP for new ones, right?

DSC/DTC ≠ Limited slip differential. There is a good reason why the M3 (and any rallye car) has LSD. LSD provides balanced power to both wheels, optimizing power & traction. If you want to take corners at speed, LSD is sweet. It is also way better in snow. Spinning both wheels will get you going much better than braking one to the point of not moving.

Putting the lsd vs dtc discussion into perspective, it is like splitting hairs. If you want traction, the ultimate point to point driving machine in common roads under variation of driving conditions is awd. Nothing comes even close as shown by the awd dominance in rallye for a quarter of a century. As we all want to argue about minor details, I argue that for 100% of forum members for any practical purpose dtc is equivalent to lsd. It is also 'sweet' to change the mode by just pushing the button. Moreover, 335 is as fast as M3 in the corners despite of more weight and less power. There is a reason 335 does not have lsd. Never underestimate Bmw.
