what is the best place for ecu upgrades

I have an 89 TII that has a downpipe no cat apexi dual n1's. also an hks air intake. Do I need to get an ecu upgrade? I have heard from many that I do because I need to get more fuel thrugh that engine. I really dont know to much about ecu stuff so if you have one please inform me so that I dont do any harm to my beloved 7!

You should get...

...A fuel cut defenser... Plugs into the pressure sensor, takes 30 seconds to into =). Goto mazdatrix.com (mazdatrix FCD) or rx7store.net (HKS FCD)...

I would say get what he said... plus some 680 or 720 secondaries, and a S-AFC to tune with.

Even cheaper get a Walbro fuelpump and pump rewire w/ that FCD. $130ish and keeps my '87 w/ TID mod, downpipe, presilencer and ported wastegate running rich at 10psi-just overly rich in low and medium boost. Yes, it is still best to get a computer upgrade if they can add maps above factory fuel cut so that you don't have to add a bunch of fuel and only need it when the ECU is reading less boost than you have going.
