does anyone have a couple of maps or a tune that i can check out? i am trying to smooth out my tune at the moment and would love some advise or at least be able to look at what others are running.
I'm running a AEM EMS on my RB25 with a GT3076R. it puts out for sure(420rwhp :biggrin: ) but I'd like to smooth out the daily driving bits because, well, it recently became my DD.

I'd prefer to see AEM maps of fuel, ignition, and such but I'll take what i can get. or if you can even point me in the right direction the help would be much appreciated.

email me at

thanks
Eddie

Eddie I'm going to fire you an email here right away

I'm on ViPEC, gt3076 as well but I'd like to take a look your maps. I can share as well if you'd like. My fuel ones will probably be useless but the ignition ones you may find of use.

eh?

What's happening that you need to smooth out?
Fuel maps will vary greatly with each set up. Even with the exact same set up we can have vastly different numbers. Do you have o2 feed back enabled?
The timing map you can just use the supplied base .cal for comparison.

i seem to be running a kinda rich when I'm out of boost(but i don't know exactly what to look for.) and the maps look great near WOT but down low they have a couple of spikes (ignition map) or irregularities that i just want to make sure are either necessary or bogus.

i'll take a look at the base cal though. thanks.

eh?

When it's rich is o2 feed back on or off?
The ignition spikes you are seeing maybe the the ecu trying to compensate for something. Usually it's to compensate for idle rpm when you see that happening down low. Go to Idle->Advanced Idle-> Ign vs Idle rpm . I usually just zero it out.
