UTEC load points
Why is not possible to be in any load point less than 60 in the UTEC? If you drive slowly, with low throttle and you have a low open loop thresshold, it will change from load site 0 to 60. At the other hand, if you smash the throttle to the metal at low rpms, you will start at the same load site.
It's a little dissapointing drive the car just in the edge where the UTEC changes from closed to open loop, because the parameters in that column aren't correct for a low load. I mind, for example, I have a ignition timing of 22 degrees at 2500 rpm at the 60 load column, that is perfect for a hard pull (full throttle), but that is very low for a low load drive.
Here is a part of a log showing the problem. You can see that I have all the time the same possition on the throttle, and more or less the same rpms, but the UTEC changes from closed to open loop, making the timing jump all the time.
My car is NA.

is that just shifting the whole fuel map down a load point or is it still running all the way to 90% load....for some reason i dont ever see 100% load only 50 -90%

I just pulled my timing until it detected a knock.. then pulled back one degree from there. I gotta visit a dyno shop to complete my tune..

I only increased timing from 5000 to red line, because I was told to don't touch the 4000-5000 zone because is where the cams switch.
I'm runing now 34 degrees of advance from 6000 to 7000 and still not registering knock
I may try to increase 0.5 degree more.
