im almost done building my 91 hatch
i have a d15b non vtec, and it was carburated so i did
the mpfi swap, i have a a6 intake manifold i believe [it has the thick fuel rail] and all that, its good now, but i heard that the
pg7 ecu might give me better performance than the pm6
is this true? it plugs in and everthing no problem, im not driving my car yet
so i cant see test drive the ecus thats why im asking
and also, is it better to have an auto ecu when you have a standard tranny?
thanks

pg7 runs richer than the pm6 thats all.

with my experience of doing mpfi swap i used both ecus with the pg7 at wot it fell on its face but right after had a nice kick.

i was using a d15b2 with intake,header it worked out ok but i could smell that it was running allot richer than before the swap.

just stick with the 5 speed ecus.

**edit also with a stock a6 cam**
