Has anyone got a hires pic of the symtec labs egt board? It looks like it might be a 558 chip?
Thx.

does anyone have a copy? im looking for the peculiar parts article in this edition.
much appreciated.

"A titania lambda sensor works like a coolant sensor. It changes resistance as the air/fuel ratio goes from rich to lean; but instead of a gradual change, it switches very quickly from low resistance (less than 1000 ohms) when the mixture is rich to high resistance (over 20,000 ohms) when the m...

So what mA does the typical ecu feed a titania o2 sensor operating in the 5v range ?

The yank stuff was for catalytic convertor equipped carb cars cause a convertor needs the fueling to swing rich then lean then rich like closed loop fueling to feed the convertor enough oxygen to burn the bad stuff some had an air inlet on the convertor as well to feed in fresh air to burn Yes that...

My Thoughts run like thds: IF the maths tfrom other inputs, and calcutations... eg both temp sensors and calculations such as BLM are all added and subtractex together anb fxnally applied to the BPW, at that moment i could JSR to a routine that recalculates and applies to a spare output to vary the ...

***late nite inspiration*** might need to clean this up in the morning So, not being satisfied with the norm, Ive been wanting to do this for a while, Im about to push the button on a minuki feedback carby, they came out in american astrons et al, they did have an ecu run them. the FBC simply replac...

Or so I've been told, yet I see No 1802, and that crystal means the chips are running at 500hz , I think
