    Here's one that may trip you up a little. It's the car facing in from the left.

    I don't know, all the cars in that picture are serving 1 purpose. They're blocking my escape route from stealing that Shelby.

    That mustang is the original King Cobra drag car. It only has about 6,000 miles on it, 1/4 mile at a time.

    Sorry. I have been doing something more useful than trying to identy cars from a partial picture.

    I have been writing some algorithms to alter boost based upon the output of a flex fuel sensor. I have to decouple the amplitude from the pulse width because the combination the two give fuel temp/alcohol content. Controlling boost requires a DC signal that then inturn goes bake to a PWM signal to control a solenoid.

    Bill I remember 3 of those at a drag strip in York Pa.

    Getting their clocks cleaned by a Vett form S&S in Philly.

    When you're really good a partial picture is all you need. besides, you can put a pilot control on that solenoid and make it work whenever you want.

    So what is there to work on? DC <-> PWM is easy sounds like a job for a little micro. 15 minutes and done. :tongueout:

    Not really. The problem comes down to knowing the octane of the fuel. A mixture of E85 and premium can be anywhere from 91 octane to about 105. To be able to run highest boost possible, the alcohol content is needed to know how hard it can be pushed.

    Sure, the boost map can simply be re-programmed with every tank (or always run summer blend E85...but even that might not be 81% ethanol..or always run 91 octane fuel). But what I want to do is have the car know how much boost it can run based on the octane of fuel in it. Automatically adjust.

    Its sort of like a trabant. Yes. one CAN measure fuel level with a stick, but that gas gauge thingy is a pretty slick alternative...

    Not that hard, just having to make sure everything is scaled correctly.

    Usually by post fifteen I will identify it. Remember all those Brewster bodied Springfield Rolls Royces. Well Brewster also built some complete cars. This is a 1915 Brewster knight Landaulet. The Knight designation means it has a Knight sleeve valve engine. It was called the Silent Knight because it had sleeves for valves.

    this is not really a bump. Brewster went into business in 1810 and was in business til the late thirties.

    Here is the Brewster most recognizible.

    I'm pretty sure it's not a Honda Civic.
