Hptuners wideband formula. I've tried playing with the input linear chart, from 5v/10 and it gets closer when I use . (Your Wideband manual will list this) Step 3: Enter the data the formula gives you (see the green box above) into your HP Tuners software. 2 while the wideband analof value supplied to the HP Tuners transfoem will be 14. 2 and HPtuners says I'm at 15. That is the formula. I also included my graph settings to make sure that they are right. Since the HPT interface has analog input and ground inputs, the wideband is being analog grounded to the same place as the PCM. 3L motor with the Z06 cam. 5)+10 Other guages may need a different formula, this should be documented in your wide band guage leaflet of what voltage euqals what AFR. Voltage Range= Range of sensor, typically 5 Device Range= Range of AFR that your instrument is set to read. I own a 2001 Silverado with the 5. A special tip for wideband users How to connect the LC-1 for wideband and narrowband outputs Dynojet Wideband Configuration MPVI Pro Connecting Pin Out Which Wideband is Right For You? I like to set things to be 0v=10AFR 5v=18AFR this makes our Formula for HPTuners volts/0. If you don't have a Graphs tab, go to layout, add to layout, graph. it seems as you can get a rs232 serial to usb and plug that cord into the serial data cable the mtxl comes with and then somehow setup the usb input as the wideband. I've done my searching but have only found partial answers (at least to my newbie skills). No thread on this after over a decade worth of posts here?????????????????????????? :bigshock: Is it because most custom PIDs would be a bit different for different applications so people don't really bother (sharing their PID formulas)? :confused: I want a thread with everyones custom PIDs and math they used in it. After I graphed the scanner data how would I go about adjusting the tables I have an AEM 30-0334 gauge/controller and I just ran the wires to connect it to my MPVI Pro. 42105263)+7.

So now you have to adjust the Transform Offset value accordingly. May 6, 2020 · Next you need to setup a user math parameter that will take the EGR voltage and calculate the AFR based on AEM?s formula you can find in the Wideband documentation. In this case, the wideband controller is calculating AFR and then generating a voltage based on that value. Right click in the graph, select graph layout . I'm pretty new to tuning and recently had the opportunity to get a wideband 02, I've heard this is an awesome way to fine tune your vehicle. I have the formula provided by 100*/equivalence ratio commanded. What is the formula we are supposed to use? I'd like to stick with AFR instead of lambda for Trying to tune for 14. 0 to get this to work? Sorry I'm still really new to all of this as well lol Apr 22, 2009 · got a zextronix wideband any have the magic formula to get this to work with hp tuner Not familiar with the brand but what are you looking for exactly? Do you need to know what formula for hptuners or what? This is meant to serve as a basic how-to for setting up an AFR or Lambda ERROR graph (histogram) for vehicles with regular VE tables (i. 625 + 10 in this diagram we also see that our 14. I set up an AEM wideband through my EGR on the ECU. Please assume a Feb 16, 2016 · I'm trying to setup the scanner to read AFR through my AEM Eugo wideband through the AC pressure switch. I just wanted some input on if my formulas look correct at least as a starting block, Jun 20, 2018 · Are there any good how to's on setting up a wideband using the ac pressure sensor? Everything I find is either out of date or to difficult for a beginner to follow. It is perfectly accurate with this wideband as it has a calibrated resistor built in, but can be free air calibrated down the line if needed (sensor degredation). Jun 26, 2016 · This is the first time i will be using the new AEM x-series wideband (30-0300) vs the old uego. I'm using AFR not lambda. The MVPI interface measures that voltage and converts it back to AFR. --------------------------------- First go to the Graphs tab. For example if you setup your LC-1 to read 10-20 AFR So immediately your commanded AFR wil be 14. I have the documentation for my wideband which includes the voltage to afr/lambda chart. 1. All of the googling it done leads me back to how to' on the old version of HP tuners. not virtual VE). But what do you do?You look at the manuals, and it looks like this:SCT Analog Input with AEM Series X UEGO:HPTuners Pro Link with AEM Series X UEGO:So Mar 2, 2010 · The most common support question that we are asked is how to setup a Wideband in Hp Tuners. You've order the gauge and adapter (hopefully of our site) and now you're ready to go. So is there anyone who could walk me through exactl what I need to do in 3. I'm using an AEM 30-0300 wideband I've noticed that my wideband reads a little different (. Covers Offset formula and HP Tuners Formula. For instance my wideband gauge will say I'm at 14. You will need In HP Tuners For the AEM guage the formula would be =(EGR_Volts/0. However, I dont know the formula to create the settings needed in the Cutom UDE i/o. I called AEM and got their formula for it and it was closer but didn?t work. quote from your link:HP Tuner Scanner • Now that the wiring is done, you need to set it up in HP Tuners. Learn more. Now, before you think 'this guy just wants us to do the work for him' I should note early on in this All standard wideband should have a 0-5volt signal which is the one you'll need. It?s reading the voltage and I?m able to get AFR but it won?t match the gauge, it?s off by about 5 points. 2 on my wideband it shows as rich on my eq ratio. So since I couldn't find one after days of searching, I Hello, I am wondering if I could get some help. I'm using the same formula that the manual states and what HPtuners has by default. 422v/7. Does someone know the precise formulas to work backwards to arrive at a Gen V VVE value without using a logged Volumetric Efficiency value? I've been using something that's close, but it's certainly not perfect. Start the engine and let it come up to full operating temperature. I've changed GHuggins, in your experience, how has the AEM wideband performed in quick throttle snap readings compared to other options, and have you encountered any challenges with its compatibility with HPTuners due to software changes?

I thought I would reach out to see if anyone might help to refine the calculation. A couple questions I do have is when you are logging the info in the histogram chart, do you use average or last value (when tuning the VE using ltft and stft values)? Files specifically for our Wideband Offset. The download is free. Below is a snippet of Java code I've been using to experiment with known values. 5 to 1 point) than what HPtuners sees when using the proper transform ratio (V/. 312, but its still just a guess. . This assumes you already have your wideband working properly. Here is the screenshot and the formula: the equation goes like this: volts / (voltage range/Device range) + (Minimum value of device range)=AFR This breaks down as follows: Volts= Incoming voltage reading, typically between 0-5 VDC. 3125. 12 in VCM scanner, but my math seems to be wrong, because at 14.
