Yes, each bag is a different color. I have I thinkg 5 reds for 12V, then greys and blues and whites for coil and fuel. Colores are optional stuff and the shielded for analog.

I didn't get a lot of time this weekend. I got the throttle bodies assembled to the manifold and working nicely. Also I found a place for the throttle actuator and get it mounted, I just need to do the linkage now.

In the other category a massive valve showed up as a Christmas gift. Now I idea what its from but it's pretty cool and funny becasue I was joking tyhe other day about saying heck with it and just throwing in a big block.

I've got one piston to go along with that valve. It's Uuge. My son used to work in rebuilding/maintaining those engines in dump-generated methane co generation applications. Heads off (one per cylinder - need a chain fall to hoist each one off) for decarbonization and a valve job every 6 months. Nasty job. But he does know the location of just about every dump in Southern California.

Glad to see the valve made it into the project. And you found the biggest block I have ever seen...

Okay. We have all been very careful to stay on-topic in this thread. ... However, those valve and engine photos are just too crazy to be just posted out there without explanation. Unbelievable. I don't even know where to start Googling.

Is that photo real or Photoshop????? What is that engine for? What is its hp? What is it's displacement? Is redline above 4 rpm? What on earth? What the ...?

I'm not sure where I got that picture but here's a bigger engine the makes 80080 KW at 22-102rpm:)

I finished the throttle linkage and put power to the actuator.....and the throttles move.

It does seem to be pulling quite a bit of power so either I need to pull some springs off or maybe use both throttle outputs on the ecu so I don't over heat the drivers. The only thing is they won't be on/off together exactly I don't think....so I'm not sure what it would do exactly.

So you're using an external actuator to drive mechanical throttles like ETC but without ETC TB's?

How much current? Our ECU is rated at 5a continuous/10a peak per H bridge.

You could also do separate actuators left/right, this would split the spring load in half. I've often wondered if there were efficiency benefits to running unequal throttles bank/bank, for various reasons.

The engine is a MAN diesel for the power station at Alice Springs in Australia's Northern Territory. Movements like this are not uncommon out here particularly when mining is on the up.

Yes. The actuator is from an M46 BMW and designed for exactly this purpose....but it only drive 6 TBs in there application. My TBs are ducati 749/999




I had it hooked to my battery charger and it was pinning the needle at 10A but a little manual PWMing got it down to more like 8A. I checked the actuator this morning with my not all the that great multi-meter and got about 0.1 ohm...so it's about a 10A device.

The ECU has a pair of 5A continuous/10a peak drivers but as I said I don't think I can sync the PWM so I don't think I can gang them. I'm thinking what I'll do is use 4 outputs to drive external solid state relays and have 20A available and not have to worry about it.

I'm also thinking that while I think the throttle sets feel about right I could probably lighten up the springs by about 1/2 to reduce the load...not sure though as I do want to be certain it will self return if power is off. I did pop the spring off the actuator and the TBs still close just fine.... I'll have to play with it a bit.
