Correct - I do actually understand how the ecm uses the maf signal!
Its just not my experience even if it is yours. (which doesn't make either of us right)
Logically if all my Synergy and mafam/digimfam customers had 'high' failed mafs and their engines were therefore being overfuelled by the ecm, then:-
a)there'd be no loss of performance (apart from that due to gross over fuelling)
b)the Synergy or mafam/digimafam would exacerbate the problem.
