i have a 93 wrx with a chipped z4 ecu and pump and reg and 3" exhaust,
i connected the wires under the dash and it said airflow meter,so i replaced,the took it for a run with both sets of wires connected and it flashed up code 32 which is lamda sensor [the one in the downpipe right?]
the problem before all this and after is that the car seens to make around 0.9/1.0 bar up to 4/5 k revs but doesnt feel like it and then when your up the revs it feels like something kicks in and away we go but like i say it seems underpowered even for the booost it producing until high up the revs,
the problem is even worse in lower gears and not as bad in 3rd and 4 th
i even changed the chip in the ecu but no difference,iv had a classic with exactly the same set up before and it was much faster and responsive than this
as another point will a lambda sensor for a uk turbo be ok to fit to a wrx
all help greatfully received

im going threw the same problem in my 93, car feels flat,
mines thrown up a error with the idle control valve so have one on its way to hopefully cure this.

Guys don't forget the outside temperature will effect how the car performs. Heat soak is a horrible thing and a big possibility considering you will both be running slanty intercoolers.

This did stick in my mind so ive taken both blanking plates off to remove some heat, and the car still pulls like this at night time, but you could be spot on so its probably time the fmic gets bought!!

Lamda is in the headers on the early cars. If you see a connection into the cat pipe, its the "cat on fire" sensor.

Thanks for replys but it's definitily not a heat problem
it's is some sort of fault as when you get high up the revs
it all comes on song more or less
on the other point will a o2 sensor from say a Uk turbo be
compatable
also does anyone know if an o2 sensor would cause this problem
thanks
