ive never seen anything about this, but since a 2g MAF running with 550cc injectors is almost equivelent to stock 1g maf and injectors, andthe timing goes alot by the MAF signal, shouldnt you have to retard the timing to compensate for the lower aiflow signal to the ECU to keep it from advancing too far?

 

i've never really thought about it either but yea, that would make perfect since to do....

 

it seems right, i just know this other car runs 100% better to drive itwith a 2g MAF over a hacked 1g maf.

 

well i read not to long ago that the 2g maf is a lot more precise as for metering the air so mabey that's why.
