Shaft speed increases and decreases depending on motor and load. It's a very simple mechanic. I should of probably just gone with the DSM ecu "load". You know g/rev...You can't get 60k rpm on my motor under 1700rpm, nor can you ever have 20k rpm with the motor over 1500rpm... so it's a super...

EvoAuto fell off the planet. It is flat you know ? His main issue is trying to control boost with rpm. It's never really going to work out and I've touched on this subject on my forum. There's really no point to putting this giant turbo on a vehicle then not go for max flow. If it flows too much...

So I guess I'm the guy that's "fighting" with my controller ? LOL. My full blown controller has Bluetooth and an android tuning app. But good job at the stab mister I don't want to start a flame war.If anyone did any of the hard work getting this turbo on other vehicles it was Steed and...

Yap you need an arduino.Check the wiki for the interface plugs I have them all there and a link to mouser to get all you need.http://wiki.lilbb.com/holset_vgt#connectors http://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=41789a1002

Lot of time and effort into making something simple for people to use. It's no turbo commander haha, but there's so much control and ability just leaving it on an arduino... you could setup a xbee remote LCD screen... all sorts of stuff... on the cheap.I may have a box solution for it, just...

Video update :

Things are going amazingly well!I've made 2 versions of the shields, and 1 total board revision. Through-hole design for the DIY guy, and a SMD version. I would suggest checking out the Wiki here. This shield is completely plug and play minus you wiring the header harness.One guy has already...

Why don't you bring your car down to my house, and I'll show you how a real man does it ? I've driven plenty of DD vehicles in my hay days, the thing I hated most was the idle noise, sorry.But in all seriousness, it isn't uncommon for my truck to have dual discs, and yet no one complains about...

Okay cool, now we're on the same page completely.I want to reply to your entire post but save space on the page, haha. We're all at least understanding each other well now, :).The potential energy in the flywheel isn't going to change regardless of how it is applied, either by the edge, or...

Why is the flywheel torque exponential to the motor when it is the motor that is adding to its inertia ? Now I know a big ass wheel spinning holds inertia, and its proportional to its weight and circumference. I just can't see in my minds eye, how it is some kind of factor of anything from the...

Yes they will spring back, but they will not propel the vehicle forward like you previous said. Not a play on words, but more so an accurate description of what is happening. Those tires sure are storing energy, in the wrong way, i would just say that's a parasitic loss.This is where you and...

Those wrinkles in the tire are not going to spring or propel the vehicle. The wrinkles are going the wrong way for that to happen. The wrinkles are the tire buckling under power and it running itself over. The tire is rotating in the direction the driver wants the car to go. So the wrinkles...

How is it immeasurable, yet you have math ? Very very confusing.The thing I don't get is the 'shock inertia'. Because a clutch disc, unless it has substantial instantaneous 100% grip friction force, actually ends up slipping. Then you start to loose your force no ? What about tire flex ? What...

Objects in motion like to stay in motion yes, I'll agree with you there.I feel like, there would be some measurable thing somewhere with actual data. Like maybe on a dyno ?Cause there is this carAnd now I'm worried for the earth when it puts its torque load inertia thing down, cause...

I absolutely had to stop reading right there. Math * your statement - logic = ROFLIf it isn't measurable, it isn't real is it not mister science, or should we have faith ?This has been a great read, now I am informed that DSMs make more torque than your standard trucks, I wonder why no one...

I thought I would update this thread a bit, I've made substantial progress with my controller. So much so, that I've made a Arduino Shield, that just mounts on your Arduino.. and you can power it directly from your vehicles +12v (on ignition would be best), it has CANBus, Turbo Shaft speed, and...

You're welcome, glad to help. Happy to see someone else doing their own thing.

http://ceddy.us/wp-content/uploads/eb23c_v05.dis_.txt^ Disassembly, probably come in handy for you.I'm not exactly sure on all the opcodes for the processor, but skimming through the diss it looked similar to the 68hc11 so you can check this list...

Makes me wonder though. They talked about a cam driven one for basically anything but drag racing.Talk about a cool system though. Reminds me of boats with cam driven water pumps (I have one with that). I didn't see a dollar sign though unless I missed it..

Dry sumps pull vacuum in the crankcase just so you know. They don't evacuate it but that's not what I'm asking right now.Magnus quoted vacuum up to 20psi of boost.I would rather hear from anyone that has seen one to see if it does what it says it does though.

Anyone have any info on magnus's dry sump ? http://magnusmotorsports.com/products/dry-sump-products-services/magnus-4g63-dry-sump-full-kit/

Oh I'm sure.So how many big power dsms have you seen with real pumps ? I'd imagine probably zero, I certainly haven't seen any.The whole electronic smog pump crap, really blows since they end up burning out cause they weren't designed for continuous use either. Just wondering what is really...

I can't help but feel like Calan is a personal friend of TexasTurbo.You admit, 2 cars post 800whp don't run vacuum pumps but just catch cans.There isn't going to be an argument here whether they work or not, the argument is that a DSM with a vacuump pump is rarer than a black unicorn with...

Might want to have someone weld a drain fitting on your ic, lower than the bottom so it actually holds oil, then you can lift the car on one side and have the oil move to the drain.

Its difficult to find a flawless system. Everything has its draw backs, belt setups or low / high draw.I really liked my exhaust setup it just plainly works.The big deal is to have a system that is engine speed dependant that you don't have over draw and pull oil in the wrong places.Intake...

Exhaust was working for me until the flapper failed, only way I noticed was dipstick popping out and oil at the valve cover bolts.I need to relocate it further down stream maybe two into one with a y to increase flow. I've never noticed anything with the exhaust no build up, etc

I'm there with my truck, I'm tired of an under carriage collecting dust and grease cause it can, so I revamped my crank case venting.I've had exhaust vacuum dump and turbo ingestion.I would imagine guys running high power just don't care for the relatively short amount of time the motor is...

Video does a good job of showing that, yes you literally can spool it immediately. My project is going very well on my truck. Just so you know, I have the controller setup for idle control, so once shaft speed is under what I consider idle, it goes into full open and waits. Once shaft speed is...

BTW, verified with the speedo reel setup, it is a VR sensor. :-)I also got the ring made today, and it fits like a glove, sanded it down and used a hand mallet to press it in. http://forums.ds-map.net/development/he351ve-controller/msg7211/#msg7211

It's 3 pins for the vr sensor, 1 is plugged, that'll help you narrow it down, I believe it is an AMP connector.I got a 24v fishing reel setup, I might try using that to spin the shaft see if I can get anything out of it.

I got em from mouser, was a ton of fun researching the right crap, you can't just do a visual even though you know the manufacturer. If you're looking for part numbers once I have it mounted and running in my truck I'll update my thread with a BOM

I already have everything lined up, I'm making a loom next week, waiting to either mill my own adapter or just fork out the money for the one on ebay to mount it, either way, all the hard work is done.I'm going to try to find an investor, and produce probably 50-100 units, since cost is pretty...

At maximum opening the HE351VE should be at around 27cm, which is why it can basically be its own wastegate.Name me some other 60lbs/min turbo with a 27cm opening ? Or post a link to the requirement otherwise stop with the FUD.

Depends on your description of the word proper.If you want max power potential, all you need is boost reference. And then scale the vein position as boost rises. If you want a little safety, you reference the VR sensor in the housing, which my controller can do. All the other aspects of the...

HE351VE certainly controllable through Arduino. Wouldn't you imagine under 140 would help clean out the veins ?I also found a mode that seems to cycle the motor from completely open, to closed, and then it shuts off. ie: Needs to be re-powered.Here's a video though of what my controller...

So what have you actually done ? Baud rates by themselves don't seem to achieve these speeds.Have you altered the serial port interrupt ? That's where I'm headed I just need a bit more debug information on the bit flags to finish what I've written.I've gotten the port to unload data at over...

I'd just like an answer if you're using the padded data as a part of the calculation for data throughput.Like your top example, is 10/sec, your second one realistically is still only 10/sec since the data never actually changed but on a multiple of 3.Just looking for that answer so I can...

I wasn't talking about the ECU heartbeat 0x00.RXTX java library, uses a 1ms heartbeat to communicate back to java of serial port changes. Including updating the size of the rx / tx que depth, clear to send, data terminal ready, Xor, Xoff, etc.Without ECMLink chimining in if they are...

I surely don't appreciate the condescending tone, hopefully that can be removed next time around.I really wanted to talk about Ardy to ECU but this is the wrong thread.Can we talk stock before improvements that way there is a foundation of which to build upon?I've got a log from TP...

It looks like a lot of reading comprehension fail here.Basshead are you going to start up a new thread of the same type, ardy to DSM, so you won't have to worry about cluttering up this thread with your own information and source ? I seemed to me you didn't want to clutter this particular...

Never ?http://www.dsmtuners.com/forums/newbie-forum/472964-1g-ecu-port-expander-project.html#post153362904Never say never I guess.So how about a new post so you can share you code ? And we can let this thread die with the op abandoning it.

I thought this was the newbie section ?Where is the source code or is this only for one person / secret forum ?

Is it bass like music or fish ?

keyspan's are the only usb to serial adapters that i know, support the 1953bps the ecus communicate with.

your too kind

pretty sure its his logger cable preventing the pwnage
