Guest lustful Posted January 30, 2004 Report Share Posted January 30, 2004 bavarian hot rod.. since the last thread got locked i will answer your question. atleast i think you have a question. on matts vette, we can't get the feul curves just perfect mostly because he has this O2 sensor that sometimes just measures nothing so i am trying to adjust a feul curve without having anything to base it off of except how the car reacts. It just intermidently does this we haven't found the rhyme or reason yet.. i think he is gonna try to put in a heated 02 sensor from a ZR1??... hope this answers your question.

Guest drifter Posted January 30, 2004 Report Share Posted January 30, 2004 why dont you edit and ask these guys about the oxy sensor? Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted January 30, 2004 Report Share Posted January 30, 2004 ahhhh yes, i forgot the c4 on twenty 2s had Haltech stand alone. , I think? as far as the ZR1 O2 sensor, If its a 5 wire, awesome. If its 2,3,or 4, you might want to get a Bosch LSU4 or the NTK UEGO. Switch type monitoring wont give you anywhere accurate results. Quote Link to comment Share on other sites More sharing options...
Guest lustful Posted February 2, 2004 Report Share Posted February 2, 2004 to be honest.. i forget which standalone it is.. and it isn't on 22's ( he just told me about it this weekend.. he could have had a sweet ass deal on those wheels) anyways.. as far as the 02 sensor goes.. i am not 100% on the number of wires.. from some cross reference his dad has it seems to match up fine.. are you saying that if the zr1 has five wires that it will work.. or that it will give sweet ass results? what we run into is when you floor it it just reads some bizarre number that won't correct no matter how much feul you put to it.. so it has to be the 02 sensor .... i forget the exact explanation behind it.. it needs replaced bottom line Quote Link to comment Share on other sites More sharing options...
Nate1647545505 Posted February 2, 2004 Report Share Posted February 2, 2004 Generally: Narrowband = < 5 wires. Wideband = 5 wires. (plus a controller) graemlins/thumb.gif Im fairly certain that the ZR1 is NOT a wideband unit. It would most likely retail at > 120$ and people would demand it for DIY WB kits. And it will not be a match up part. So right now im going to label it as narrow band, just the fact that its heated may help Lambda readings. If you are using standalone, a stock O2 sensor is not going to work for tuning. I really dont see how it would even work with it in the first place. Stock Sensors are referanced around Stoic, it would simply try and get it to read .500mV in closed loop. at WOT, O2 data is like pissing out of the door, its ignored. And it should read constant value around .900-.915 for a "healthy" WOT AFR. What value is it reading ?? Quote Link to comment Share on other sites More sharing options...
Guest lustful Posted February 2, 2004 Report Share Posted February 2, 2004 well in the program itself it reads the a/f value.. not the mv. the values that it gives me is something around 10.1.. but soon after you let off the throttle it comes back to near stoic or right at it depending on how much of the throttle you let off. thinking back, i think they wanted a heated sensor b/c the thought was that the sensor was not getting hot enough under WOT to get a proper reading..thus a heated sensor was desired.. oh and BTW i think the sensor is right around 80 bucks.. might be wrong Quote Link to comment Share on other sites More sharing options...

How are you tuning this? VIA ODB2 port or serial from the haltech? Autoptap? ALL SYSTEMS will read the output in milivolts (mV),and decode it. Wide Band just can output Linear voltage, and most units have a display to decode it. If you are using a stock O2 (aint a wideband), it will really F up your whole tune. A ZR1 O2 will make no differance. The sensor is working fine. Best hope now is to strap it to a Dyno, and tail pipe sniff it. Quote Link to comment Share on other sites More sharing options...

Guest drifter Posted February 4, 2004 Report Share Posted February 4, 2004 the o2 sensor thats in it right now is the stock single wire pice of shit. I think its lettin the car jump in and out of open and closed loop. I thought maybe puttin a heated sensor in it would at least keep it in closed loop, Quote Link to comment Share on other sites More sharing options...

I thought maybe puttin a heated sensor in it would at least keep it in closed loop, that doesn't nmake much sense...closed/open loop should be dependent on engine load i.e. TPS problem. then again it wouldn't be the first time GM has done something i didn't understand.
