    Need help from an electronics professional

    Yup I sent Cableguy here to hopefully get some much needed info. Not sure what all that means either Jimmy but we will look into it. Thanks.

  4. Re: What would cause my AFR to be a half point off

    That could be a possibility. And would make sense. It probably would be a simple -.5 to whatever the current formula in there is. I will check into it, thanks!
  5. What would cause my AFR to be a half point off?

    I'm running a Innovate LC-1 wb with hookup to XD-1 guage and logging via HPT EIO inputs. HPtuners consistently reads about .5 higher a/f ratio than the xd-1 guage will display. Car runs 12.4-12.5:1...

    Re: Enhanced I/O Interface recall / repair

    Should we be expecting a 2nd email then?

    I can understand shipping on a hardware upgrade, but paying shipping for a defective part! Great! :banghead:
  7. Cheapest, simplest, permanantly installed wideband

    Looking for the minimal hardware WB o2 setup that will function with HPT. Alot of these WB's have a ton of bells and whistles, including thier own software, which is useless with HPT. I'm looking for...

    Re: What are the "best" threads in this

    Get the fuel "close" first IMO. Then get the spark "close". Then adjust both slowly to their final values. Without a wideband you'll have to rely on the stock o2 sensor voltage and trust that your...

    Re: 1 OR 2 Wideband O2

    I would just put a bung in the other side. When you are comfortable with the tune, and it is consistent, switch the WB to the otherside to verify that it matches.

    As far as the tailpipe WB, unless...

    Re: Switch between NA-N02

    ah, even better :) Using a resistor to change coolant temp would allow for spark and fueling changes.

    I'm not at home to look, but aren't there alot more things effected by coolant temp than...

    Re: Switch between NA-N02

    Chris,

    are you referring to the EIO outputs triggering relays? And what tables are you referring to? Are you trying to hint at something coming our way in a later update.....?

    Re: Switch between NA-N02

    Also, with this setup you wouldnt have to worry about the low octane table, you could copy your high octane table to the low table. Everything is fully adjustable within the IAT correction table.

    Re: Switch between NA-N02

    You have to wire up a resistor to the IAT sensor from the WOT switch. When you go WOT, it trips the resistor and tells the car the intake air temp is like 175 degrees (an unrealisic value that you...

    Re: Proper way to set Idle RPM?

    I could be very wrong but I think it may be under the ENGINE>IDLE>IDLE RPM tab.

    Also you can adjust idle in realtime in...
  16. Re: Why does it go stoich at WOT? Jimmy, Keith, Ch

    woh

    looks like your o2's drop off from around 900 to the stoich area while the rpms come up. Have you verified this with a wideband?

    Re: When to stop adding timing???

    I have had it up to 34 before, but the week after I dropped it to 32-33 and the car "seemed" to run a little better. I really need a dyno to find out at what timing does the HP peak. From what I've...

    Re: How does KR work?

    Lighter than most but not by much. It's a formula with true duals and no back seat. Nothing spectacular. Some weight was probably dropped with the deletion of the heavy muffler in the catback system,...

    Re: How does KR work?

    Knock or "pinging" on a mostly stock car doesn't usually hurt anything because the stock engine management system is pretty good at picking it up and pulling out timing. However if you are on nitrous...

    Re: Confused on cylinder balance issues?

    Thought about it some more, and have a theory. Maybe it is just a guage of how much a given cylinder "contributes" to the entire engine. It is called a "balance" test. One cylinder is shut down, and...

    Re: Confused on cylinder balance issues?

    But what does shutting down a cylinder, have anything to do with how strong that particular cylinder is? It's not like a compression test, or is it? Or maybe it is an idle tuning aid?

    It shuts down the cylinders one by one and then measures how much the idle drops. I'm still trying to relate it to...
