Base map for BT

[shawn.]

hey guys i am gonna be finishing installing my ATP GTX3071r this week and i was hoping someone could hook me up with a base map for the turbo so i can get it up and running? or even help me out a little with where i can find some info or something. thanks

Who will be tuning you? I'm sure they can provide a base map.

gonna be self tuning. i tuned myself on the stock turbo and feel confident i can tackle this as well.

So, make your own base map....

Do maf resize, set wgdc to 0...

Biggest thing is changing scaling the maf if you've upgraded to a big maf as stated. Then depending on ebc or mbc, set it low, set timing low, set AFR low. And start fresh and slow.

Area of new maf/area of old maf

Like Richie said, take the cross-sectional area (pi x radius^2) of the new larger MAF housing and divide it by the cross-sectional area of the MAF housing you currently tuned your car with. Multiply the result by entire MAF curve. Then perform MAF calibartion.

Set your entire WGDC table to 0 and zero out the underboost side of the Boost error comp and load error comp. This will allow you to run on spring pressure and not allow the ecu to add any WGDC to achieve targets.

This is the best way to start a BT base map. It will allow you to run as little boost as mechanically possible while you get all the basic things dialed in. Also, you may want to run a richer AFR until you get things dialed for safety. Then later you can lean things back out and work your way up on boost. Take your time.

Ok so 3 inch just take go with 25 percent. 3.5 use 66 percent. That'll get you running. From their you do the same shit as before.
But the simple math is (new maf id/old maf id) ^2
Also depending on how you installed things you may get boost creep. Don't freak out and panic. Just keep tuning and it'll go away.
