Re: Project Frankenstein - full ECU shield

Have you considered selling these as a "kit"? Presumably if you order the parts in quantity it will be cheaper than everyone buying them individually. It would make it a heckuva lot easier for someone who wanted to try it too... Perhaps recommend that they buy an assortment of 0805 resistors/caps ch...

88-89 carb had one type, 89 auto was its own thing (different wiring harness, ecu, distributor...) 90+ were the same. What year are you working with? If its a 90+ it should have an optical sensor, same as on my B6.

Re: '92 Festiva with 1.6L SOHC

Everything is still hooked up in my car like it is from the factory, and I'm getting the signal by back-probing the the connector at the ECU. So the ECU is still hooked up to the circuit. The opto sensor has 12v going into it so I'm guessing there is an internal 5v regulator. I can "borrow" a piece ...

Re: '92 Festiva with 1.6L SOHC

With it hooked up like this, but not connected to the signal wire, I started the car - the tach values were all over the place. And the signal wire was not hooked up at all? I unhooked the 5v from the opamp and it dropped to zero. Then I hooked it back up and same thing - so I unhooked the ground th...

Re: '92 Festiva with 1.6L SOHC

puff, that's what I did - rotated the engine by hand (but with the key "on" so that I had power to the sensor)

Good idea to check the fuse... it worked fine last time I used it but it has been a while. And yes, it is an optical sensor, same as the one I took pictures of.

Do you have a multi-meter that can measure around 10mA of DC current? Can you measure the current in either the power wire or the ground wire for the optical sensor? Can you tell me what it reads both when the op-amp LED is bright, and when it is dim. Also what is the voltage? I know it's 5V, but i...

So, what do you we call your engine configuration file? Mazda 323? 90-93 Festiva (1.3l SOHC) and 90-94 mazda 323 (1.6l SOHC) use the same general engine management. Meaning, you can run the 323 engine on a Festiva ECU. The distributors are the same part number, VAF can be interchanged (although the...

I wouldn't suggest anything smaller than 18 AWG carry more than an Ampere more than a few inches. Not necessarily because it can't, but because of the heat build up.

The ampacity for 18ga wire is 14a. No offense, but your implication that 18ga wire with >2a current is a fire hazard is absurd. Can you share the calculations you've used to back this claim?? For example: I wire industrial control systems running 24v at ~1a with 22ga wire (short, 3-5' runs). Max pan...

Are we talking about making an entire harness, or just an extension? 18ga is more than adequate for a few feet, especially if it isn't bundled tightly in a harness. Of course if it makes you feel better you can use thicker. Sure won't hurt! I'd be OK with just soldering the wires to the board throug...
