Check out www.needhams.com... There PB10 programmer will do up to 4 megabit devices (27C040) and is expandable with adapters to do 8051 etc...

I have two projects in the works for the '730 that eliminate the eprom. the first adds a Dallas Semiconductor battery backed up ram chip and makes the ecm reprogramable in real time over the aldl (small code mod also required)(<$50). the second replaces the eprom with flash. the mods require a couple of jumpers be added to the cpu board, but it will be much easier to alter code/tables. john gwynne ------------------------------ Date: Tue, 29 Jun 1999 17:04:56 -0500 From: Steve Ravet Subject: Re: DIY_EFI Digest V4 #386 > > Date: Tue, 29 Jun 1999 21:50:11 +1000 > From: "Geoff Richards" > Subject: led O2 sensor > > I have a 10 led o2 sensor that is commonly known to the list > I would like to be able to check the operation of each individual > led by applying the correct voltage to the signal wire. > My question is how do I make a SIMPLE variable voltage source > for this. > I have very LITTLE understanding of electronics so to any folks > kind enough to reply BEWARE it will need to be basic > I posted a similar question to a newsgroup and received an answer > that I really do not understand but would be able to send to anybody > willing to help out. > Cheers > Geoff Geoff, try this: take a regular 1.5V battery (C,D,AA, whatever). Get a potentiometer from the Australian equivalent of Radio Shack. The value doesn't matter too much, something from 10k-50k should be fine. Get one that says "linear taper". Don't get "audio taper", "log taper" or anything like that. Hook it up with the battery across the end terminals of the pot. Connect your LED meter to it's usual power source. Also connect the ground or common side of your LED meter to the negative terminal of the battery. Finally connect the middle terminal of the pot to the LED meter signal input. As you turn the pot, the signal voltage will vary from 0-battery voltage, about 1.5 volts. You should see the meter move accordingly. - --steve > - -- Steve Ravet sravet@xxx.com Advanced Risc Machines, INC www.arm.com ------------------------------ Date: Wed, 30 Jun 1999 00:33:24 +0200 From: "Espen Hilde" Subject: Re: DIY_EFI Digest V4 #386 I have seen some weber -marelli fuel pressure regulators that are adjustable. But Fiats are maybe not so common in your aria, I had a problem with the bosch regulator , it wasnt able to dump enough fuel at low output, this weber marelli unit cured it and is adjustable.

Is there any formulas for figuring exhaust flow by horsepower level? I was looking at some Dynoax mufflers and there is one they rate at 0 backpressure at 600cfm. What horsepower level would that be? It has three inch inlets, so it should be fairly decent. greg kring ------------------------------ End of DIY_EFI Digest V4 #387 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
