I am planning on putting a BB turbo setup onto my 91 SE-R. Can I use the BB ECU in place of the stock one, or do I have to use a JWT? And if so why? I have been told that yes I can use the BB, so long as I use a O2 sensor from the BB. I have also been told that you can use the BB ECu but several wires need to be moved around. Is there any one with actuall experience with using the BB ECU that can answer my questions? or can anyone direct me to someone who can give me a definite answer.

Thanks

I have the BB ECU installed in my NX2k since 3 week, and it's seem to work pretty good. But if you have the money to buy the JWT Ecu, it would be a better than using the BB Ecu :)

I'm also using the BB ECU, works very good. I have a nx2000 and I don't have erratic idle problems.

Using a JWT ECU is pratical when you change your injectors, increase boost pressure, change MAF, etc. You can increase boost pressure on the BB ECU, but the reprogrammed ECU will be better tuned for this boost pressure. But it works.

Just think about all the DSMs that increase their boost pressure on stock ECU...
