Yeah, they're keeping me busy!.. got 14 now.. one born this morning was darned near frozen stiff, but he's fine again!  Might lose the tips of his ears though

I've been doing lots of turbo work for a friend, he's a better salesman than I am,.. so I do the machining work boring out the hot sides on HX35's from 60 to 64 or 67mm.. Just getting into doing the cold sides now, a bit more tedious, but I make some more money, and I'm still cheaper than getting it sent out so it's a win win

I've got an issue with the VGT on my truck right now.. not exactly sure what it is, but it's sticking in brake mode mysteriously.. and it's not even after it's been commanded to go into brake mode! It seems to report position 585 when it's having an issue, I'm going to replace the actuator and see if that helps

So it seems like the Aeromotive A1000 pump I got at a pawn shop a few years back for cheap will pump diesel happily.. One more piece of the puzzle solved.. and apparently, while a bit ugly, you can rebend the VP44 lines to fit the P pump... Considering they want $700 for a set of lines, I think that's what I'll go with... I'm not sure yet, but I might do a stage 3 cam as well and do some head porting if I'm pulling a head off.. Might try welding the cracked block too, maybe do the head gasket after that in case I got it a bit hot... I'm thinking of putting a vacuum on the cooling system while welding to keep the impurities out of the weld, not sure on the welding process yet, probably TIG, either bronze or nickel filler, or perhaps arc weld with a cast rod...

OK, a little more...

few weeks ago the first gen suddenly ran like CRAP... turns out the head gasket blew between #4 and 5 cylinders.. it was one of the old Felpro that were notorious for failing,.. really thin fire rings, and generally poor build... got that fixed.. there was some pitting in the block and the head, I put a skim of muffler cement on it and let it set up, then hit it with some heat and reassembled... I torqued the stock head bolts to 130 with lots of lube, they felt nice there.

Over christmas I was at the coast in the first gen, tranny started leaking bad on the way down from the bellhousing, figured tranny input shaft seal.. borrowed a buddy's shop and hoist to swap it out, did the rear main while I was in there.. apparently that wasn't the problem, so out it comes again, turns out the torque convertor was cracked by the hub, easy to miss if you aren't looking for it!.. I had a spare TC, just a stocker, equally slushy in feel, but I tossed that in and it's been behaving
I put 1500 miles on it in a week, everything seems to be behaving.

I bought a 47RH with a low stall non billet single disc convertor, came with an ATS billet flexplate.. I already have a 47RH but the pump is pretty rusted, so I figure with the two of them I should make one good one no matter what... I'd like to find a billet input as well, but I'm a cheap bastard... I'm getting a rebuild kit, new bands, clutches, etc... another shift kit.. 
Maybe this truck will get a VGT at some point... I'm making a black box to control the tranny already.. Oh, I forgot, I bought an ATS 3 piece exhaust manifold for a 12V brand new but due to some mishap one of the turbo mount stud ears got cracked.. maybe it'll get that.. I'll see

I also did work on tractors over the winter.. the Holder A12 has been repowered with a Hatz E89FG engine, heavy monster, but runs good, I'm just tying up loose ends on it now, waiting for an oil pressure switch, etc... I rebuilt the kink steering with new bushings, put new seals the tranny and final drives

Can't remember if I mentioned it earlier, I got a TIG welder last fall.. had some fun making the exhaust from stainless milk line.. I'm certainly no expert, but it still turned out OK for a tractor

Last but not least, I have babies being born now

I've been busy..
It's calving time again, got 4 babies

My friend has started selling custom turbos, he gets housings, I do the machine work on the hot sides to take them from 60mm to up to 67mm

I also bought 2 24V engines, one is a VP44, the other is a P pumped engine, but lines not included.. P pump engine is a cracked 53 block, but the P pump on it is a 230 hp industrial... last year I sold my core 160 pump for a stupid high price (I asked for an offer) and that goes a long way to paying for this

I'll try and post more thorough updates later

the biggest hurdle i see is the 24v actuator for the holset.. do you have a good 24V source?
Perhaps as 12V version from a 351VE could be put on in?

After that, I think it would be quite trivial to make the LBB take a PWM input and convert it to something the Holset actuator can use

The LBB is a complete standalone unit, if you want to add external logic programming, you can. You'd need to measure your PWM and put it down to a 5v signal so it's measurable if you wanted to go that way, but the control logic built into the LBB is quite out standing.
General Discussion / He431ve pwm input from ecu to canbus actuator

I have a bmw 330d (common rail, piezo injection 3.0td) that uses Bosch edc16 engine management. It drives the original Garrett gtb2260v vnt turbo using a Hella actuator and pwm data signal.


I have a holset he431ve (29cm) that uses a (I think) 24v can-bus actuator, the big heavy duty version of the actuator as you'll know - it's water cooled and very hefty. With gearing on the 3phase motor.


My original plan was to run the holset with the Hella actuator, but I don't think it'll last or work well as the Garretts use pivot vanes that are very light and easy to move compared to the holset vgt sliding mechanism.


That means I have to get the holset actuator working. Is there any way an Arduino based on control unit like the LBB that is somehow able to utilise the original edc16 pwm signal Input to output a canbus signal to control the holset?


This would allow me to retain the ecu control and have some hope of spooling this monster turbo adequately.


Otherwise I'm limited to boost pressure actuator or possibly even trying to use two Hella actuators to operate the vgt in parralel. Not sure it would still work.


Any input or direction would be greatly received. Thanks and sorry for the lengthy post.
