Hi Andy In a word yes. Just make sure to keep the same order/color wire to the stepper motor Idle could be real exciting if you don't Other wise no Pintle shape is prob more important.

This was resolved by making 2 axel shafts out of 1 to have the reluctor Ring on the CV boot. The management systems of these engines torque limits at launch to alow these front drive high power cars to be driveable in all weather conditions and the axel speed inputs may not fully clear the problem. The Northstar may act as a completely different engine if you can convince it to run on a ZR1 Corvette ECM. (This may be more work than is worth, too $$$, parts hard to find.) Does your engine proform well after what would be a reasonable launch and hook up in the stock car?

I wanted to use this processor as the programing experince gained would apply to GM systems and be a step toward understanding EFI332 programing.

Look at the tailshaft, that's where the sender is. If there's a speedo cable coming out then you have a mechanical speedometer, and there's an optical head in the dash that provides a signal to the ECM. It's two little paddles on the speedo cable that interrupt an infrared led/receiver. (at least, that's the way my '86 S-10 is set up.) If there are wires coming from the tailshaft then there's a magnetic VSS sensor in there, and you have an electronic speedometer. - --steve - -- Steve Ravet steve.ravet@xxx.com Advanced Risc Machines, Inc. www.arm.com ------------------------------ Date: Mon, 29 Mar 1999 17:11:18 PST From: "Chris Moore" Subject: Re: Chip for Northstar Hi, Yes it does hook up after a bit. It really kicks down when you are in passing gear. I really don't know what to do. If it is because of the wheel sensor inputs, can't I make some kind of unit to produce a signal to make it look like it is always moving? Why can't I get a chip made to get rid of this all together?

Cooley" Subject: EPROM emulator boards Hello all, Pricing is in on the Eprom Emulator boards... Double sided boards, with component silk screen on top will run $30.00 US each. Delivery is 3-4 weeks. What I'll need is to get a check from everyone that wants one as the company wants the orders pre-paid (since I'm not a company...) This was by far the cheapest of the 3 companies I got quotes from... All that are still interested just let me know and I'll get my address out to you.

Does that name ring a bell? I have an old Honda CB 750 that he built for a lady around 1971. Man, does that bike rip! Anyways, I was surfing the net and decided to look up RC. Looks like he is still kicking butt, but now his specialty is EFI. Does anyone know about his products? Specifically I am looking at the high impedance injectors. I am hoping to use a 749 ecm to control a big hp motor. He is a thumbnail sketch. I am planning, and actually building, a 1946 Buick Street Rod. It will be powered by a 540 ci. Caddy, port fuel injected by via the adaptation of a Ford 460 MPI manifold. Now this is where I get the looks. It is going to be turbocharged. The turbo is more for novelty, kinda keeping with a Buick theme. The motor made 400 hp and 550 ft/lbs in stock form as a 500 ci. I am guessing with all of the mods the hp will be significantly more so let's say 800 hp at 15-18 lbs of boost isn't unreasonable. These RC injectors may be the ticket for allowing the 749 to control the beast. Thanks, Paul Tholey PS.
