While I understand the beauty of Silverleaf and now BlueFire (which is a thankful addition to the market, given that it uses bluetooth) for engine monitoring, the issue I have with both is needing a powered screen for output.
We wanted to keep it simple, uncluttered, and don't think we need tons of gauges, just the basics. Perhaps we'll upgrade to BlueFire later but for now, we're going to see how the Scangauge D will work for us.
Because we have a 2000 Magna and cannot find a 6-pin or 9-pin Deutsch port anywhere in the vicinity of the dash, I've purchased an adapter for the rectangular diagnostic port that we do have under the dash,
J1708 ALDL Male to 6-pin Male Adapter. Hoping to get enough data off the 6-pin (which is really only 4 wires: 2 data wires + 1 ground, 1 power). Hoping it all works.
OBD Diagnostics has a ton of adapters & options, just btw. Great customer service, as well.
If not, well, plan B...or C. One expects to be flexible & patient with an older (but awesome) rig!
