this is the limit... doesnt matter what MAF you put there, if its calibrated to what the ECU wants to see.

as an example: get a MAF that outputs 1/2 the voltage as stock... then when there is 33.827 pounds/min, the ecu will only see 2.5v.

Now the ecu will only add fuel for 16.9 pounds/min of air...

see the problem..?

the only solution I see is getting injectors with double the output... this way the air/fuel ratio will work itself out!

Some maxima guys are using a Z32 MAF and 370cc Z32 injectors with the stock ECU. The readings from the Z32 MAF are ~49% lower, and the 370cc injectors provide around ~54% more fuel, so it effectively works it self out as you said. To fine tune they use a FMU with small ratio disc and lean it out with a SAFC.
