Here we go 96 civic Ek sedan s40 b1000 Had blown y7/y8 mini me Equal length t3 manifold,true hks ssqv bov, true 38mm tial wastegate at 4psi,evo 560 injectors w/resistor box, no name turbo ugh, obd2a to obd1 jumper, integra ecu chipped and vtec installed auto to manual 3 bar map, FITV delete with real block off plate. Swapped in a d16z6 used y8 im with hondata Im gasket, used new z6 dizzy,cap,rotor,wires, step colder ngk plugs, with jumper harness. Fuel pump primes engine starts but has real bad idle thru whole rpm range. Have checked TPS and MAP voltage it's dead on. Iacv is new but hums when key on. plugged iacv hole in TB with fingers no change. Then covered TB with hand while surging sucked like a vacuum died right away then still had suction till pulled hand away so rule out IM gasket. Cant rev while surging just sounds like hitting rev limiter. For ***** and gits tried a Virgin p28 ecu from same car that the z6 came out of nothing, no start or even pop WTF is going on

 

What's your AFR look like at this point?

 

Bouncing are 11 and 12

 

Pulled ECT sensor off when surging and it idles and has full rpm range seriously the ECT sensor.
