Guys,
I am looking to get my hands on some maps, on to realize that there is no map sections available for different tuning options. I am going to push this through the various engine sub forums in different flavors. But I will start here, and please follow format. I hope we can get enough so we can borrow, tweak and upload.

.020 8.5:1 bottom end
BC stage 2 cams / gears
Greddy intake manifold
550cc sidefeed injecorts
FPR PSI XX

I would post mine, but it is a work in progress and I am running a GTR PFC on a RB25.

any sensible person should know this, but you may want to update the original post with some disclaimers about using someone else's map. even if your mods are the same, a different motor may run completely different with the same map. doesn't hurt to take a look for comparison purposes, but one BIG thing is the PFC is blind to ignition timing. it assumes your ignition timing is set at 15 BTDC (rb20/25) and 20 BTDC (rb26) and goes from there. so if someone's CAS is 1 or 2 degrees off from yours unintentionally, this could mean bad things at peak power.

This by no means is a "here download this map and use it", but rather get you in the area so you can modify from a good starting point (typically most people will use it as mean to get running to match modification so they can either get it tuned, or tune). As for the disclaimer, it's ECU tuning, if you don't know how it works and that you can cause damage then don't try. Oh Axpexi supplies the disclaimer.

However on your not of ignition timing, that is a good thing to list. As I have no yet started tuning mine, but I have noted 16 degrees advanced

yeah...timing is a good thing to mention for sure. whenever i'm using someone elses map, as a rule of thumb i typically take 3 degrees off the whole timing map across the board then as i mess with it can add it back in a degree at a time if i feel it's safe. then tune the timing from there.
