This is odd because I've never read about anyone having a voltage increase across the lines, only a drop. If Block Learn is at 0% everything is just right. Make sure Plus and Selected are bubbled in. If the vehicle seems to be running decently no pinging or potentially problematic situations drive it around for awhile. Only way i was able to use the read function of hptuners.
I would rather have more accurate data over a tighter use-able range than less accurate data over a wider range. If you have a shift kit, leave max line pressure at 90. So you would get unlimited flashes on them for 2 licenses worth. Step 2 — Things to remember before you start tuning Whenever you make a change, you should save it as a completely new file and you should name the file after whatever changes you've made. I recommend doing this any time you want to get data as accessories, car chargers, battery condition, system voltage, etc can all skew ground offset and slope. By far right of table I have shift pressure up to 96. Navigate your gauge and menus with ease by touching the bezel of the gauge.
Mount the controller inside the vehicle away from heat, water, moisture, dirt and all moving parts, in an easily accessible location. Not every motor can achieve this though. By doing so the air-fuel ratio remains at 14. It takes me literally 5 mins. This view is histogram 6 with the initial run on the bottom.
Thanks, Dave After what could be a lightbulb just going off, I may have figured it out. Should the unit output closer to 5V when in free air? Cruising on the highway is a good place for this as you can cover all rpms and a wide range of mph. Not only does it save time but also avoids variability in the narrowband sensors. The key will to be initially setting up your wideband outputs so you know what you are working with. This component easily fits into your fuse panel and provides an additional fused power wire for accessories such as gauges. Now, drive normally with nice slow acceleration.
First and foremost, leaving a sensor unheated in an exhaust stream or with frequent extremely rich misfiring can cause rapid failure in any system. Start with 10 and then you will need to adjust from there. These values can be known and set with total objectivity. If they are enlarge the hole. Idle is the best place to start. The table can also be hand smoothed using the 3D graph. I use edit or I would let you look at his tune.
Laptop computer Outline There are many different ways one can tune a car, but below I have outlined a methodical process which should work well. This is very handy as all you need to do is just drive smoothly and obtain whatever cells you can. Using only for tuning and specific monitoring periods will extend sensor life. After making the changes, go back to step B and repeat until the oxygen sensors are in the 890mv to 900mv range. Start your truck and get your O2 sensors hot.
I have been reading posts on Wideband O2 and have a couple of questions. The first step in this is to record a long log file of driving, a minimum of 20 minutes, but the longer the better. I bought that one so I could swap it back and forth between my car and my buddies c-5. The only tricky parameter to set here will be injector constant. Here is how I did it: Good info. I then took the middle and started beefing up shifts in increments of 10 then increments of 15.
To view links or images in signatures your post count must be 10 or greater. Do this until they are acceptable. These values indicate how the computer is correcting. It is recommended that all tuning sessions be done in like weather conditions. I also know that I can purchase the update from hp to do tuning on the fly. You currently have 0 posts.
Which one can I use as a scan tool on basically any vehicle without buy a license for each platform? Most cars seem to like narrow band oxygen sensor reading between 890mv - 900mv. So it's just that, a closed feedback loop. After working through 3 additional sessions looking from the bottom up , you can see the improvement. You can tune with confidence knowing that we have developed a safe, effective and repeatable process for you to follow. The adjoining cells should be smooth not spikey.
This method uses the stock narrow band oxygen sensors which are not accurate for this type of tuning. Then you put the key in the ignition and turn it to the run position without starting the engine. Even if I have to drive to someone, it'd be worth getting a good tune and be able to actually put in my cams and meth that have an inch of dust on them from sitting waiting for a good option! I have been able to get the gauge to display lambda so I have to be getting closer. Perrsonally, I haven't messed with Lambda. Just under that, give it an abbreviation of your choice.
