A completely new program for the Syclone/Typhoon! Many improvements to the chip programming to improve cold starts, idle, response, and general driveability. Can be programmed for the stock 2-bar MAP (stock injectors only) or a 3-bar MAP, although a 3-bar MAP is recommended for better boost control. Also includes the ability to read a wideband O2 system (connected to the ECM), and makes corrections at full throttle (above 10psi boost). It will also emulate the stock narrowband O2 if you have a wideband connected to the ECM, so you can remove the stock O2 and replace it with the wideband sensor.The chip is programmed for your setup and the tune is normally fairly close. If adjustments need to be made that can't be corrected with the chip's adjustable parameters, then I do free adjustments for a year from purchase. This does not include changes to the combo (like injectors, turbo, heads, etc), and does not transfer to a new owner.
So i just got my plx dm-6 gen 4 wideband combo and will be running a narrowband simulation with link but had some questions.1. How many have put the wide band in the stock o2 location without problems.2. When tapping into the o2 pin for the ecu can i just pull the wire back or do i need to cut it and splice.3.
Wheres a good place to run the wire from the wide band to the module inside the car4. Where should i pull power from.5. When using a narrow band simulation i only need to use the wideband input correct.6. When using a resistor for the o2 heater wheres a good location to put it.ive searched and coulndt find direct questions to my particular answers.
I have mine in the front 02 spot, no issues. If you're worried about heat, you can make a copper heatsink really easily. That's what I did. I used these sheets:2. You don't need to cut the wire if you can pull the sheathing back enough.3.

Plx Wideband Wiring
Make a small X cut in the rubber boot around the steering column on the firewall and run it through there.4. Any 12v source. Try finding the wire to the cigarette lighter, that's always a good one.5. Wire the 5v output of the wideband to the front o2 pin on the ecu (pin 4 on 1g). Enable narrowband simulation in link, then set the switch point to 2.35 according to this:I don't know about number 6. I have mine in the front 02 spot, no issues.

Never had a need to simulate a narrow band O2 sensor. Just install the wideband in place of the stock RF O2 sensor, plug in the controller module & start tuning. This will put the car in open loop. Once the AFR is tuned, then reinstall the stock O2 sensor.Russ KempI wanted to simulate NB because this is a daily driver and I installed the PLX DM-100 gauge which you can set up to give you all kinds of warnings and custom displays based on the parameters from the sensors. For instance, if I'm WOT or at the track, I can set up the parameters in the gauge to flash a warning if boost is over 8psi and AFR is over 12.5, or something like that, so I can let off the throttle before I blow stuff up.I was going to install another bung for the wideband, but it turned out that I didn't have enough room in the header collector, and the only good spot I could find to install the bung would have been monitoring only one bank of cylinders.
Alright, I'm using the PLX for both wideband and narrowband. The problem I'm having is that in reads the same in open and closed loop; like it makes adjustments to inself.Just to double check my wiring. The positive and ground are wired into my cigerette lighter, narrowband is wired into my O2(D14 if I remember right), widband is wired into D10 ELD.
Download Setup Manual For CARSOFT MB 74.doc from Sendspace.com - send big files the easy way just follow the install guide which is also. By an antivirus program. That's not true. My copy of CarSoft 7.4 works fine and sounds no alarms, because I removed the Trojan while leaving the crack intact. I have tried a download and the cd that comes with it. I keep erroring out at some point. First i couldnt even install the first setup. Then i found a download link with carsoft files and i was then able to succesufully run the first set up. Then the crack.exe wouldnt work so i cant get pass step 2 now. Thanks for purchasing the MB Carsoft 7.4 Car diagnostic device.

Do I need to wire in the 3.3V and GND on the analog connector? Are they just another positve and ground?And please don't give me that stupid link. I've looked at it so many times and I've almost gotten nothing from it.EDIT I can make adjustments and it will read identical to what it was before but it's obviously making the changes.

Do I need to wire in the 3.3V and GND on the analog connector? Are they just another positve and ground?Sorry, I don't give your reading skills much credit.Your PLX documentation explicitly states to not use the cigarette lighter for power ('dirty' power, bad readings).My first suggestion is to fix that. Maybe run it off of your 12V and ground for your stock 02 wiring.NB goes into the stock 02 signal (D14), WB goes into ELD (D10).Make sure the ELD is disconnected (leave the old part of the wire disconnected, not spliced in) and your ELD is NOT disabled in SManager, otherwise it won't read the voltage coming in from the WB.Turn on datalogging when you turn the key on, and check your ELD in the sensors window to see what it's reading.Should start around 2.4-2.5v and climb to 5v over 30 seconds or so, while the engine is off.

I tried all the recomended grounds plx said and then some the only way i got mine to work was i oldered it into d14 aswell as the NB wire. Works great.here is the link to plx's recommended groundsWhat? Could you make that alittle easier to read?My ELD reads 1.3V. I had it disabled, but just tryed it with it enabled and it did nothing. I have read through the tech section plx wideband connection guide and found it confusing.
But, I think I figured it out. The way i understand it is you can wire the narrowband to a spare o2 plug on the white wire and it comes out on d14, then the 5 volt wire to eld. Or, you can just use the 5 volt wired to the white wire on the spare o2 plug, and then the wb 5 volts would be on d14. This would only provide wb signals to the ecu, and you would have to run in open loop all the time.

Do I have it right? If not please correct me. FreshDA9 wrote:you take some wire crimp on the plx connector and pin it into the lower left 4 pin on the smf. You then will solder it into one of their grounds but it worked better for me when i soldered it into the NB wire. Just like the few said before.do like spunk said take a datalog and post it with your bun for more help.So I should wire both NB and GND(ground) wires into the O2(D14)? I just wanted to clarify.Oh yeah, I installed the PLX gauge and it says rich 95% of the time, the other times it'll jump to 12.4(hella rich) or say something else(can't remember).
