General Discussion / Re: HE341VE Compatibility
« Last post by crodgers on February 15, 2019, 01:39:46 PM »

Thanks for the info Hak. Yes, the connectors are the same, the 341 appears to have the 300vg style connector, and the 351 obviously has the 351 style. The wire colors are another story. I'll have to get those sorted. Saw another post about that on here.

Whatever I do, I need to stick with the 341 compressor/turbine. My turbo application is on a 3.0L diesel and is plenty large as-is. I did some more reading following this post and found a fellow who swapped the 341 components over to a 351 to make a "hybrid" unit. That netted him the use of the 351's 12volt actuator. He also had a few other reasons for doing that. But I'll see if I can just swap actuators for starters.

Absolute worst case, I'm wondering if a can just run a 24volt step-up transformer, relayed between the actuator and the LilBB, to feed it it's precious gucci gabbana 24volts? The CAN signals should still be 5v for both actuators I would think?

Personally I don't know.

Are the connectors the same as the 351 ? Does that turbo have a shaft speed sensor ?

I know the 351 and the 300vg all communicate with the same addresses, the 300 just more finicky about starting position.

Hey Guys,

Could someone enlighten me as to whether the lilbb is compatible with an HE341VE? There is little information available on that turbo (unlike the 351), from the little I have found, I've seen mumblings about the 341's controller running on 24volts as opposed to 12volts. The controller itself I'll add is slightly different in form. It it has 3 coolant ports up top, whereas I believe the 351 only has two (inlet and outlet).

I do also have an HE351VE on the shelf that came with the project I'm working on. I'm wondering if I could just swap the controllers across and call this a dead issue? They look to be crosscompatible but I'm unsure whether the actuator arms are different in length or anything. Thought I'd ask  you gents before I dig into it unnecessarily.

Any information is greatly appreciated! I'm about to pull the trigger on the v2 lilbb but need to sort this first :)

Got everything working now.  Thanks for everyone's support.  I think this will be a great upgrade and make towing a little nicer  8).  Also looking forward to quicker warm ups lol.

The old first gen is getting new shoes tomorrow.. got some cheap 20" rims.. totally flakey bling chrome.. Bedliner then gold flake clearcoat.. I think it'll look alright

the 94 truck is getting the new injector pump tonight.. Yeeehaw!. Also found a NEW actuator for about $270 USD which will give me a completely new turbo.
Bank account isn't all that happy, but I sure am.

Meanwhile there's ANOTHER truck i"m looking at buying, 01 QCLB dually 6 speed.

If you're already filtering power somewhere else before it get's there, you're fine. But noise is bad for 5v components.

The board powers up and functions without it when connected to my PC through FTDI, so I guess it's okay so far. I'm going to use a voltage reg board to drop 12v down to 6-7v for system power, so maybe it won't be needed.

I would if you could,  if it is a Vin cap it's to filter out noise.. If you just can't get to it, do you have a pair of neighboring VIN and GND pins? just solder it across there.

GM’s early attempt. It’s not even meant to be a workhorse like the Cummins and Powerstrokes, but it got better fuel economy, allegedly. Exactly why I wanted to replace the turbo with a much more efficient unit.

Well, now I gone and done it... I was trying to come up with a more permanent solution for the LCD components. I soldered the CAN485 board to a small breadboard, and didn’t like the orientation of the right angle FTDI header, so i thought I would just desolder it and flip it around to the other side of the board. Well old ham hands here managed to pry a compnents off of the CAN board, I believe it’s a capacitor from the Vin circuit. Think it will be ok without it? Or do i need to try to get it back in there?
