HPTuners or EFILive?

[Rich Z]

Anyone using either of these two programs? I'm thinking about getting one, but not sure which one would be "best". Both seem well liked by people using them, so maybe either would be sufficient. EFILive has a pending upgrade last time I checked, so I'm not sure how far that one is from being released. I think HPTuners just had a new upgrade not that long ago.

But one question I have in mind is how useful these programs would be WITHOUT a wideband O2 sensor? Honestly, there just is no practical way for me to get under my car to dink around with the sensors, so what I have in place is what I am going to have to use. I've heard you can use a through the tailpipe sensor, but if you have cats it will throw off the readings.

So would getting one of these $600 programs be just a waste of time and money?
