Default Romulator, Wideband

Ok so i'm going to do another CRX turbo, i'll be staying OBD0 so i was just wondering which romulator to buy to use with Turboedit, I understand that on the fly tuning is possible the the latest bin if you use a commercial romulator, so if i'm wrong correct me, if not advise me!

Also as i am wanting to tune for myself i will be needing a wideband O2 sensor, i bought the diy wideband but the sensor costs an absolute fortune so i was thinking of buying a commercial unit that uses cheaper sensors, any recommendations?

A bunch of guys are just now getting there zeitronix wb's. I just got mine today, we've figured out a way to datalog read rpm, afr, throttle, and BOOST without the boost sensor. It's the perfect tuning tool. and it's only $290 shipped.

Just got mine today so I'll see how everything works this weekend.

so if i got that i wouldnt need to get the romulator, because i could log a run make changes, log a run, makes changes etc until properly tuned, am i correct? also i wouldnt need to buy another boost guage as this can display boost and vac pressures?

if i am right then, damn the thing is a ------- bargain

yeah, that's generally how you tune using data logging

yeah, with the program you datalog your run, then you can see the play by play in the program. It comes out as graphs so you just move your cursor over a certain point and you can see all the info for that cerrtain point in time. So you just look under where your afr needs to be tuned, (EX. look at the rpm, boost) and go into turboedit and make your changes by either adding or decreasing fuel. Then burn the bin, and do it again until you get a nice afr curve.

Having a romulator would save an assload of time. You could tune it with a laptop in the car, while running, and get it perfect; then when you're done just burn a chip with those settings and you're done. Without a romulator it takes more time... make a run, log it, come home, study log, make changes, burn chip, put back in car, make a run, repeat. :P (that's the way i'm doing it)

yeah i know it will save time, but the time part of it isnt an issue as i like ------- about with the car, and i just bought a house so the cash flow is somewhat restricted, so, compromises have to be made and if the only real benefit i get from the romulator is tunng on the fly then it can wait until i have some spare cash
