Cool, thanks. I'll give them a try once I've added fuel and tried to get the AFR down.
Thanks. That fits with the "this is set at the factory" bits I was seeing in the Monaco/Premier manuals.DMC manual specifies the advance by degrees somewhere near the ignition section (?) The Volvo ignition greenbook TP31397-1 has the curve for the OEM distributor (and a few other B27x and B28x motors) but is too old for your engine. Since the 3.0 was totally ECU controlled there is really no reason to have published the curves like this as a mechanic wasn't going to do anything useful with the data. To obtain the original spark map you would have to reverse engineer it from the OEM ECU or measure it somehow. Maybe you could find that data outside of the DMC world.
That makes sense. I know you can use a combination of MAP and TPS, too. I'll read yup on this once I start playing with acceleration enrichment.Either will work, but from what I've read TPS is preferred. It will be a better gauge of your intention. Otherwise the ECU has to watch for changes in MAP which will lag your actual foot.
Yeah, that's pretty impressively bad. I'm a software developer, so I kinda get where they're coming from (extremely rare case that has never been reported in two decades or so), but I don't work on stuff that can get people killed if something goes wrong. You'd think they might just add a maximum injector open time to avoid the risk of that kind of problem.I had a fun problem where I accidentally hosed the firmware which caused the injectors to lock open w/ fuel pump running. First time I've ever had to siphon an intake manifold. The response was basically, "meh, first time this has ever been reported. You're more expendable than the time it would take to fix"
Range is a big limitation. I would want at least 250 miles out of an electric car (which is about how far I could go on the 2.8L engine). It seems most electric conversions are under 100 miles -- enough to tool around town and get to/from work, but not enough to, visit my parents on the other side of the next state. I feel like you could pretty well pack the engine bay with lithium ion batteries if you didn't mind basically taking apart a Tesla battery sled and relocating the cells yourself. I guess you'd have to redo it every decade or so, but hopefully we'll get better battery tech at some point and you'll need fewer batteries, or get greater range.That would be fun, especially fast charge becomes a reality. With a gas engine we can emphasize its "touring sports car" qualities but that's difficult to claim if you have to make long stops to recharge every few hours
I also do wonder about how a DIY conversion would connect to a fast charger, though. Probably have to borrow a few extra parts from another car to make that work...
