LH-jetronic? Man, I'd talk to a Saab or Volvo guy. You can probably swap injectors, MAF, and ECU and be ready to go if there's a turbo version of whatever car you're working on.

The 90-something Saab LH-jetronic is a fairly nifty piece. They use ion sense to detect cylinder pressures to tune fuel and ignition under boost. That would most likely NOT be an easy setup to wire, but very cool nonetheless.

Hey J Davis, have you run the saab apc unit you were talking about? I got two saab 900 turbos I'm thinking of parting out, and was wondering if anyone had adapted them to anything else?

Yep, I recommend everyone buys one. You need to tune the knock sensor sensitivity pot once you have the APC installed, as the Honda engine "sounds" different than a Saab engine. I have a stereo tuner **** wired in place of my peak boost pot, so I can adjust boost on the fly.

Make sure the KS wire is uncut, and thread it back thru the firewall so it remains with the APC plug. The other wires you can cut off at about a foot (or more) length, those need to be custom wired anyway. You need the boost solenoid (three vac prongs, and a two prong plug) and the pressure transducer (reads boost, has VDO stamped in the housing if it's like mine).

The APC can be under a seat, or under the windshield cowl. The transducer is underhood or under the driver's dash, above the footwell near the fusebox. The solenoid is always in the engine bay/underhood. $75-100 is a fair price for them, plus shipping of course.

I want to buy the Hobbs switches off your turbo Saabs... they are under the driver's side of the dash, near the transducer (if mounted underdash). They run $30/per new, let me know what you want shipped pls.
