Chuck...think it might be something for the J&S or maybe an old Powercard? -Bryan --- On Thu, 9/11/08, Chuck Wills <[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> wrote: From: Chuck Wills <[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> Subject: Re: Expensive lesson To: "pm" <[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> Cc: "Miata Power List" <[email protected]> <mailto:[email protected]> Date: Thursday, September 11, 2008, 11:28 AM There were many 1.8 kits sold that had *no fuel management to speak of* - it relied on a resistor in the air temp sensor line, and sometimes there was a pressure switch in the dummy throttle body that would only cut the resistor in during boost. This was a real crap fuel solution. You are correct - the BPL-9 is the ECU. If you have a knock sensor, then most likely you have a J&S knock sensor somewhere. I'm guessing that's what is plugged in to the CAS wiring. The J&S used to be a little black box, and sometimes had an LED readout for knock and AFR. My first JRSC install was set up this way - no fuel management and a J&S to keep detonation at bay. It was the worst management scenario possible - as the J&S does not pull timing until knock is happening. (newer J&S are better than the old ones, and have some pre-knock retard capability, btw). I'm not surprised that things melted down on you. If you confirm that you have a J&S, you might want to adjust the sensitivity... or sell it and get a timing controller that will pull timing based on boost/rpm/temp. You really need a fuel solution though. An AFPR and better pump will probably do the trick, and won't be terribly expensive. An electronic solution like the FM Voodoo Box or Power Card from Moss will work as well. If you are sticking with 6psi non-intercooled, you'll probably get the best drivability out of the voodoo box. There are lots of different solutions and combinations of things you can use. it kinda comes down to how much you want to screw with it and budget. -Chuck pm wrote: > > > On Thu, Sep 11, 2008 at 9:06 AM, Chuck Wills <[EMAIL PROTECTED] > <mailto:[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> <mailto:[EMAIL PROTECTED]> > wrote: > > You really need to find out exactly what you've got for engine > management.
