datalogger maft

[skinnyt]

well i just put my maft on,it came with no instructions so i found one some were cant think of it right off hand,but the question i have is the logger i got as far as fuel trims are to set the base on start up and drive it between 50 -70mph on the maft is (ftrl)=84% (ftrm)=100% (ftrh)=100%...and i have no nock.so i need to run it richer don't i ? hell I'm confused about the hole thing for now.

Well if you just installed the MAFT you will want to drive around for a while so the trims will update as it's slow. Your Low trim is maxed out on the low side. Meaning it's pulling fuel at the low setting which means you are rich. Since your Mid and High are at 100% I would assume they haven't even started moving yet as you haven't driven the car enough for them to update. I drive in 3rd at around 30-35 MPH to get the mid to start moving. You can see what trim your on if you use pocket dyno to log. Also you can see when your trims start to move by looking at the subtrim. They won't start moving until your subtrim moves from 100%.

I would check your Base setting on the MAFT. Go Here to set up your MAFT properly. I'm using a 3" MAF and running blow through with 1000 cc injectors. Have the injectors compensated for in the ECU so I set it for 3" MAF and 450cc Injectors and all other knobs zero'd out.

From what little info you posted I would think you have yours set up for smaller injectors than you actually have. Good luck.

I'm running 450cc injectors iv been settin up the maft all day yesterday and so far so good.i drove the car on base setting for about 30 miles then whent to set the mid and high.so far i got 0 knock on mid and 4 knock on high.i still need to do some more adjusting but i need to reset the boost back to 13psi right know its on 11psi.i didn't think this would take as much time as it is,but I'm trying to get it right.
