My last AFR tune

[vr401]

This is my last log in 3rd gear. Finaly got the AFRs where I want it.

Total noob
I take it these numbers are good, so what does it actually mean?

Just that it's running at optimum?

11.5?

looks nice and safe

Good work!

Looks very nice.

How does it go?

Hi Miodrag, how did you get the information in a graph format like that?
What sort of wideband/software are you using? What are you using to adjust your AFR's?

Cheers

It goes good. It dosn't feel that there is any flat spots in power. I have to do couple more thing before it goes on dyno and WSID.
Knock count is just a couple sometimes so it runs very safe afr/timing setings.

11.5 it is mate and fuel map is mapped from 11.4-11.7 so 560cc are tuned good. It took me a while to tune them but it payed off.

I'm using AEM wideband read by evoscan.
Then I open evoscan log in excel and using afr readings row vs rpm readings row I make a chart/graph. That way you end up with such a nice graph. Very useful to monitor airflow readings as well as AFR readings.

Wow, smart man. Thanks for that.

Wow, smart man. Thanks for that.

Many people use it on evo IV-X because they can log the load and that way tune the maps correctly.
I'm getting latest ostrich emulator :thumbsup: that can be used with tuner pro and it can map trace the load cells too. With it I'll be able to tune maps on Evo I-III, RVR and VR4 easy.
If there is any knocks caused by high timing I'll know exactly what load cell was used to adjust timing.
