2005 bhw marine stand alone

I am building my marine vw for my jet boat, i am deleting the egr and dpf. I have removed power steering and ac, as they are no use to me.
What about the vacuum system, what function does it support?

Thanks for your time

No DPF on a BHW. Vacuum runs the VNT system on the turbo, as well as the brake boost (don't care) and the recirc flap on the A/C (don't care).

Given that pump (vacuum) also has the fuel pump integral, you are going to need it both for fuel supply and VNT function. Unless you are going NA with different engine management.

Alright, thanks for the help.
I don't think i am going to run a vnt,
But good to know regardless, i was really hoping to eliminate that system on the engine. But i guess not

How are you planning to control the turbo then?/

I am going to run the vacuum system, i was un aware of us function.
But here is my next question, i am looking for info on a aftermarket tach, and how i could have one of those hooked up, i was wondering if anybody had looked at these edge products for a all in one aftermarket engine monitoring system?

You're going to need to run the stock cluster (unless you are tuning the ECU with an IMMO defeat), why not just use the cluster tach?

You can use what you linked, you can also use a OBDII dongle with an android tablet/phone running torque for far less money than what you listed above.

With a obd2 dongle transciever your options for gauges are only what the ecu reads nothing aftermarket like a pyrometer?

And i would prefer to have something that could stay on the boat, i could see a tablet or phone being a hassle

I'm looking for some opinions on An idea i have for a water to air intercooler. This pictures shows the air and water inlets reversed. I am wondering if you think this would provide sufficient cooling in a 12" long bundle, the water temps will be at max 58°f... That is the highest i have seen local river temperatures, so having a consistently cold intercooler won't be a issue, i just can't find a awic core that fits the shape i want



And once again thanks for your comments/help

Plus you could set the tablet up with an interface for depth/fish finder, radar/GPS system, etc. I know of several people, when I was down in West Palm, that had setups like that in their boats.

A 2005 BHW is PD - so why not do IMMO delete and just keep the same ECM? EGR can be chipped out or nearly so, besides there is some arguments about fuel consumption vs EGR which may be more relevant on a boat?

Please tell me you are doing a water/water system for engine cooling. Not fun cleaning all the crap out of the cooling system. I have seen finned radiator systems that intergrate onto the hull bottom, but don't know many details. Wonder if they would work for you?

Interesting project, please keep the updates rolling in.

Interesting about the dongle thing, it's just so new to me, i guess buying a gauge that cones with all the sensors makes sense to me?

Yeah it will be a closed cooling system with a heat exchanger and sand trap to help keep most of the debris out of the raw water side of the system.

I am doing a immobilizer delete, and going to tune out the egr, based on the goo on the intake three is no way that it's a great benefit to the engine?

Have you had a look in the conversions forum? There are several marine TDI threads there although I don't think I've seen one with a BHW or any PD engine yet. Still you could probably get some helpful info. Cool project!

No need for an aftermarket pyrometer. The BHW has an EGT sensor which will read out in whatever app you use.

The BHW EGT will not read in an OBDII app like torque (tried, several times).

It will read in VCDS, just not Torque.

I did not know that. Thanks for clarifying that. How about something like a P3 Cars set up?

So maybe autometer is the easiest way,

Can anybody tell me if there is a conversion from throttle buy wire to a traditional cable throttle?

Not on a bhw.

Earlier units (alh and ahu) can be converted to a mechanical pump, not possible with this engine.
You will need to use the ecu, and cluster unless you get the ecu tuned to remove the security system that makes it look for the cluster in order to start.

Sure, attach a cable to the throttle pedal.

But in all seriousness the fueling is controlled by the ECM setting duty cycle of the injector solenoids. There is no where to connect a throttle cable for direct mechanical control on a PD.

What I would do is hook up your throttle control cable to the throttle pedal so you can keep the same marine controls.

Jason

I like that idea, just have to figure out cable travel for the movement of the car throttle

One caveat - the throttle on my boat also puts the gear box into gear and selects direction.

I assume your boat is similar? Also most boats the throttle stays where you left it where in cars you have to hold the position or it will return to idle. So obviously the simplest conversion is take the cable that pulled/pushed the throttle on the old engine and attach it to the electronic pedal.

Of course there are likely e-throttle boat controls, but they probably coast more than your whole boat and the engine you are putting in. Just trying to keep the $$ reasonable.

Jason

Also, the throttle linkage needs to cut the "ignition" momentarily when you put the transmission into forward or reverse. Or else it will grind the cogs and slam it into gear. This will shorten the life of the gear case.

Well with a jet boat there is no gear box, it is just a bucket that drops over the nozzle and changes the direction of flow.

I have come up with two options.

Dual lever throttle, one for the bucket, factory throttle for... The throttle. And remove spring and replace with fiber washers to let throttle hold in place when cruising.

Or use a single lever control

And the throttle cable portion will jump back to the throttle pedal via short throttle cable.
Spring well remain installed and the shift lever will be able to set and cruise..

Well pulled the valve cover and the first lobe is worn all the rest look perfect.. Guess a cam shaft is on store

Killing the IMOO is easy. 4 bytes. BTDT.

I thought it would be easier to make two build threads o.k. different forums. But this one is a little harder to upload pictures. So if anybody is interested in my build progress here is a link to my thread on mean chicken, the jet boat forum.

Uberhare can you elaborate on your comment please ??? [4 bytes. BTDT.]
Love to rid my ecm of the IMOO

You need a method of being able to read an eeprom on the board, change the appropriate bytes and write it back. Spend some time on ECU tuning forums, it's all there.

I'm trying to sort out my tuning, based on the parts i have bought. I live in chilliwack, bc, Canada. I have no issues shipping the ecu. But i needd some help finding a good tuner who will support me in my one off build.

Who would you recommend for a task like this

I tried dealing with Malone but i have had no response, and they require information that i don't have because i just bought a engine of eBay.

For the jet boat i believe i need:

immobilizer delete
Emitions delete... Egr dpf
Dynamic idol? (is this a high idol to warm up engine)?
Glow plug strength and duration increased
Turbo is vacuum actuated(VNT smart actuator delete)
Tuning for 220ish hp

I

This is what they offer for tuning options

EGR delete (off-road), VNT smart actuator delete, left-foot-brake fix, cruise control fix for 5th gear upgrade or 6 speed transmission swap, or a combination of these features.

Any the above features plus Dynamic EGR, Dynamic Idle, glow plug duration and strength increase, or a combination of these features.


Immobilizer delete. Your engine computer may need to be shipped to us to accomplish this. Must also provide proof of car ownership.

I would try Jeff at www.rocketchip.com. He's an engineer and might be into a project like yours.

Uberhare thanks for the reply,the one thing I seem to not have enough of but will read up, have a soon in law plenty capable of it.
Have a site suggestion ??
