If anyone has any experience with mass airflow meters disco recommended using that and afrs to figure it out, also. Just something to throw out there.

you're right, flatland - the scangauge doesn't measure actual flow, it's a calculation based on pulse width, air flow, displacement and other factors. that said, it's been pretty darn accurate for me (within 2% of "manual" calculations on the gas receipt at fill-up time).

I think Hondas since the beginning of time are open-loop at full-throttle. I'd like to know this too as I drive my TL with the auto-stick, get into 4th as soon as I can, and mash the gas.

FYI... been watching eBay for about 3 weeks now for a used laptop-connectable OBD2 unit for proper data-logging ability.

kicked myself on friday because i missed out on a real deal: it went for $50 - and the only reason i missed it is because of a web/browser glitch at the crucial bidding moment (15 sec before the auction ended).

i don't really want 2 separate units. the scangauge is so convenient since it's self-contained, no muss, no fuss. i think i posted this elsewhere here, but i did write to the company to see if they would ever consider adding a USB/serial output, and they basically said no.

how hard would it be to add one? opinions of any electronics experts??

Depends on the internal structure of the thing. OBD0 and OBD1 honda ecus it's as simple to do as adding a 25 dollar cable from radioshack because it's already set up with communications ports.

Prolly *** hard on the scanguage I'd guess though.

Re: Quote:how hard would it be
 

Wait, I thought you said it has to be chipped first to send the data? Which is it? Can I just hook up the cable to my obd1 ECU and get data from there?

It does have to be chipped
 

It does have to be chipped to send data, I was just museing on the fact that the communication port architecture, or lack thereof, is probably the biggest hassle when doing this.

The ecus have the communications port so it is just a matter of plugging in, whereas metro might have to create one (if that's possible) to even be able to access data.

I think it's time to post
 

I think it's time to post pictures of PCB's!!!!!

NM...for some reason I thought your ECU was OBD-1...then I wanted to see a shot of its innards.
