question about hptuners
question about hptuners how come hptuners dont have a horsepower and torque calulator on it like efilive does in their scanner. it might not be Accurate but at least you know if you do one thing and you drop in hp or tq then u know to change it back.

the scanner does offer a delivered torque PID.... and hp is a derivative of torque... so you could make your own histogram showing the info you want .....
Though... I fail to see what good reason this would serve (useless in tuning) other than telling your friends "well my car made 528shp!!!!
"
or
"woohoo! I added a FRAM air filter and I went from 412shp to 413shp (*shp = scanner horse power)!!!!"
To use this info in tuning though.... seems pretty assinine (sp?) to me..... (hp/tq readings are PCM calculated..... if your MAF/VE isn't dialed in then guess what.... the hp/tq readings the PCM gives you is going to be wrong!)
to get your MAF/VE dialed in you really need a wideband O2 sensor
but as I stated originally... if you really want this info... you can create a custom histogram pretty easily that will show you your torque/hp (PCM calculated) ... but I wouldn't use it to determine if your tuning is correct..... (I could provide you w/a tune that would result in well over 1000hp .... doesn't mean your car is making that power.... and I don't guarantee your engine will last long... but if you want the number.... I can give it to you)
