i can seem to get the ucc to upload the maps to the utec. i dont have the 9V adaptor.

for example, if at 5000rpms, the afr is 10.9 at load 40. would you take fuel away just at 40->100 and leave 10->30 alone?

and with all my 80 loads, where should i adjust the fuel there?

sorry for all the questions.

I would only take fuelk away at the load site logged. But, a load of 40 isn't that much and doesn't need to be as lean as say 70-100. You can run high 11s or even low 12s in the lower load sites.
Your afr should taper towards richening as you go from lower load sites to higher.
This is why it's so important to get logs from as many load sites as possible. Experiment with different gears and acceleration.
Think of it this way, before you change any particular load site (load/rpm), you need to know what it is now. When I get home today I'll try to post up my 91 octane map.

Here is a copy of my current map for running meth/H2O injection and a UCC log file from this Map.
I'm still tweaking a bit, but you get the general idea.
Don't use my values. I have a Dynoflashed ECU, different injectors and every car is different. I just want to show you what a good tune and map look like.
I'm also using a manual boost controller now. I wasn't happy with the Utec boost control. I'm not really liking my MBC either. I wish I would have sold my HKS EVC.
Hope these file open up. I've never posted anything other than pics.
