tuning a supercharged A-engine without a WB-sensor

[arnold]

Hi there

I'll try to explain the idea: blower blows into a modified TBI unit, the throttle valve removed and put upstream in front of the blower.

Engine is a 1293cc A-engine, I use a Rochester TBI unit of a Opel Astra with a more or less unknown injector. What I found is a flowrate of 19.4 lbs/hr (partnumber on the injector is #029 5278). I installed a NB O2 sensor in the exhaust.

I aim for moderate boost of max 0,7 bar, probably app. 100 HP

Well, I guess the injector is not sufficient, I'll raise the fuelpressure if necessary. My main concern is the difficulty of tuning a FI engine with a NB sensor.

If I need teh WB sensor, what do I have to buy besides teh sensor itself?


PS. I had the engine idling already but had to remove the throttle because of fuelleaking....
