S4 na rtek 2.0 how to log "load"
 
I'm running a 1/2 bridge six port and I've got my fuel trims pretty well where I'd like them to be, and now I'm looking to adjust some timing . The na table reads load vs rpm for the timing map. I know the load is calculated off the airflow, but is there a way to log load directly, or a lookup table to show what loads the different airflow numbers represent

After digging through some dinosaur threads it looks like load is just another word they're useing for the tps reading. can anybody verify this

Page 22 and 27 about table indexes and logging.

Load is proportional to airflow divided by rpm. So 100 liters per minute at 2000 revs per minute is higher load than 100 liters at 5000 respectively. I don't think the exact ecu formula for load is known but remember airflow/rpm. Look up Bosch L Jetronic. It's the same thing basically, Denso licensed the technology from Bosch.

It is not TPS based. That is called an Alpha-N control system.

....... So they have you adjust timing via a parameter you can't actually log or verify to know what cell to adjust....... That's a little suspect.

You didn't read the manual. I even told you what pages.

I read the thing 7 times, it says you can see it by selecting the correct parameter, but it doesn't tell you what parameterhttps://cimg5.ibsrv.net/gimg/www.rx7...c724364fc6.png

Is that rpm vs load, or do I just want straight loadhttps://cimg5.ibsrv.net/gimg/www.rx7...4e187fcdc0.jpg

My understanding is that you start at the origin (bottom left) and count to the right for the rpm index and up for the load index. That's your T-Indx parameters.

Given the RPM shown on my logger that would make more sense the other way around, "14xx rpm being closest to index 3 and load being 5" but I get what you're saying
