Despite being responsible for every problem in every early CS, Lewis is great. Take that PCNA!

"does this enables us to physically remove the SAI system from our cars, including the OBDII ones,"

No! All it does is fool/mis-represent what the O2 sensors 'see' when the
SAI air pump turns 'on', i.e. It basically indicates that an adequate amount
of air is reaching the O2 sensors during a cold start-up.

Why does that mean we can't remove the SAI pump and system from our cars? What am I not understanding here?

Count me in for one! Thanks Lewis. I think I still have an old Heathkit voltmeter from about 1970 that my brother built.

Wherever the "formal" list ends up for sign up, I'm on it. Never know when one may need one.

Thank you Lewis!

I don't see why not. My pump is disconnected. The SAI pump relay is still in place to show a load across the relay. I agree this is not a complete OBDII bypass, just the SAI portion.

This is awesome Lewis! Thanks for taking this to the next level.

Please put me down for 1 ea. assembled and 1 ea. kit. TIA! You da man! :bowdown:

p.s.: Still have my Heathkit strobe light and CO meter (analog...nowhere near accurate enough for today's cars.) Built many kits when I was a teenager.

Great post and Rennlist spirit! I don't have any SAI issues, but I will also like to sign up for one please!

What happened with Post #1 that Flying_low posted with the schematics and pictures? I could see it yesterday but it has dissapeared now...

That's weird. If it doesn't re-appear I'll create a web page on my server for the details.

We made a small error and moved the posts in the DIY section.
I will try to fix it now.

Ok fixed.

I would like one too. :cheers:

"Why does that mean we can't remove the SAI pump and system from our cars?"

Yes, you could remove just the pump, but why? When you remove system
components, it no longer looks stock, i.e. A possible future sale or an
overly committed emissions inspector/tester.
