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

Re:Romulator, Wideband
 

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

Re:Romulator, Wideband
 

i'm new to self tuning, i took my last car to the rolling road and just made the changes that the tuner told me to so i got a lot to learn, i would be grateful for any helpful advice

Re:Romulator, Wideband
 

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.

it just takes patience and some hands on experience. plenty of people to walk you through it when the time comes though ;)

Re:Romulator, Wideband
 

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)

Re:Romulator, Wideband
 

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

Re:Romulator, Wideband
 

It's not quite this easy. yes you can log any sensor (RAW voltage) and then play it back and see where you *think* you need to make changes...but what the Wideband is logging and the ECU is seeing are two different things

You might think you need to make a change in a specific cell, but that might not be the one the ECU is pulling its injector pulsewidth # from in the fuel map.

Re:Romulator, Wideband
 

with that said though Xeno, for the price its a good piece of kit would you not agree, and, even if it cant help to tune my car to a perfect 12 across the board at least i will be able to get it pretty good, a lot better than just feeling the temperature of the engine and smelling the exhaust gasses.

I'm not after a miracle i just want to know that my car is being tuned to a decent (safe) level

Re:Romulator, Wideband
 

the techedge 2.0 kit uses a $35 wideband o2 from a vw...get that kit in the diy version and save mad $$.

Re:Romulator, Wideband
 

I have a zeitronix, but i want to get a romulator also.. what brand(s) work well with turboedit?

Re:Romulator, Wideband
 

First off, ROMulator is not a wideband.

You guys are talking apples and prostitutes here.

ROMulator is a ROM emulator that interfaces with TurboEDIT to do realtime tuning.

Your Wideband is what you use to gather information to help you tune.

Re:Romulator, Wideband
 

The only ROM emulator that interfaces with TE right now is the one from XTRONICS

www.xtronics.com

It is the same one Hondata uses.

I will say that OBD0 cars are pretty finicky with the ROMulator. I find it easier to just pull over from time to time and make changes. Sometimes the ECU freaks out when you make too many changes to too many cells...

Many of the newer Widebands out there use the $30 Bosch sensor. The LM-1 that I have being one of them. This WB will also calibrate itself for the L1H1 and L2H2 O2 sensors as well.

Re:Romulator, Wideband
 

Yeah, I noticed that too the other night. I was able to narrow it down to getting one fuel cell to make it freak-out on a RT update. Seemed like if you changed a cell ust enough to change the column mulitplier it would do it. Could this be? I assume TE will change the multiplier if you jack the #'s up past a point?
No biggie though, RT updates make for some super speedy tuning for sure :)

Re:Romulator, Wideband
 

so what u guys are saying is you can tune on the fly but u have to pull to the side make the changes and apply it with the car on or off? the past few posts confused me a bit. :-\

Re:Romulator, Wideband
 

Read it again carefully

Re:Romulator, Wideband
 

Sounds logical to me...and if this is the case, on the fly TIMING changes shouldn't have any problems since there are no fuel multipliers. Sound right?
