Re: CCS file for Azure 445 dmoc

I’m going to look through my stuff side I have the same azure dynamics controller. I’m pretty sure I have a CCS file that will work.

Re: 2002 BMW 330ci with GS450H transmission

Not sure if I untherstand correctly but basically one mount is wrong right? One hole will needs to move inwards so can be re-used? and one outwards. Always difficult without pictures. I think you can mill/redrill the current mounts. If that results in an unacceptable quality at least you have the m...

Copper and aluminum are not a good combo.
Do you know what are the OEM bolts made of? I'm pretty certain they're neither copper OR aluminum, but the buss bars are definitely copper

Re: 2002 BMW 330ci with GS450H transmission

On a positive note, I was able to modify the Lexus transmission mount by cutting off the OEM mounting flanges where the 2 stamped steel parts meet and welding in some flat bar stock. In the E46, the mount points are higher on the passenger side compared to the driver side and also has a step (not fl...

Re: 2002 BMW 330ci with GS450H transmission

I found out that the oil pump for the GS450h transmission is shot when I took it apart to change the bearings. I guess it's better to find out this way rather than after mounting the transmission in the car. I'm toying with the idea of eliminating this unit, and using the electric hydraulic power st...

Very likely that this pump was replaced in the car I pulled it from based on the sticker. The model number cross references a Mazda 5, but it looks like the majority of them are very similar, if not the same manufacturer. There are embossed branding from "Koyo" on the reservoir and the pla...

Re: Wanted: Power posts for Lexus GS450h inverter.

I got a good start making the power posts before someone pointed out that brass has much less conductivity than copper (about 1/3)... I'm not sure if I'll continue down that path, as they also pointed out that using readily available aluminum spacers with a longer bolt will be a LOT less work.

I’m not that far along, but check Damien’s posts and videos. I’ll be at around 400v and probably limit the rpm between 6-8000

Re: Zombieverter programming help

Yeah, I think the most likely reason is that I somehow sent 12v down the uart line. I’m just at a loss to remember when or how this possibly happened without me realizing.
