I didn't get any email from the list on Wednesday
April 28th. Is everyone just out cruising, enjoying the weather? I
drove my '70 to work for the first time this year, as it is almost 80 today in
Cleveland. woo-hoo!
Since it's been quiet, I'll post an update on my
latest project. I'm starting to gather parts for my EFI conversion.
I plan on converting my 406-powered '70 to EFI using the MegaSquirt EFI
controller and a TPI-based manifold. http://www.carcraft.com/techarticles/116_0403_mega/index2.html It's definately not an easy project. Just assembling the
MegaSquirt and pieceing together a harness will be challenging, let alone the
high-pressure fuel system and then tuning the thing. All of the software
is free, and the whole design (hardware & software) is open source, free for
anyone to modify to their liking. There's a real good mailing list with
lots of knowledgeable folks. I think I'm going to start with an 80s TPI
manifold setup, although I susspect it might be too restrictive for my
combo. I hope to score some of the intake hardware at the GM Carlisle meet
in June. I got a set of injectors from a '96-98 Mopar 5.9 for free at work
today. I'm not sure if they work or if they'll work on a TPI manifold, but
they were free.
I haven't seen any postings here, but over on the
MegaSquirt list, there's a lot of talk about the newer Wide-Band oxygen sensors
(WB02). Even for carb'ed cars (who put an O2 bung into the exhaust), these
WB02 sensors can show a real-time air-fuel ratio. Unlike older O2 sensors
(narrow-band), these wide-band unit are accurate when you get away from stoich
(14.7:1 Air-fuel ratio). I imagine you could really
cut down on tuning time with one of these, not to mention increase the 'quality'
of your tune.
