i am having similar issues, I have WOT shift rpm set at 5800 but it still shifts at 4800rpm. I have adjusted boost pressure settings but still shifts at 4800rpm? Anyone have any advice on...

I was looking at your tune and comparing to mine. I am just now starting to play with the transmission. I am happy with the part throttle shifts but needing to raise the WOT rpm shifts. I changed...

Sorry for slow reply. send me a scan file. Is your wideband showing up when you scan? If it is showing up what are your numbers? Is it in lambda 1.0 or afr 14.7?

sorry forgot to add how I have the histogram set up. Let me know if this does not help or have questions?109979

sorry for the slow reply, the channel selected is in lambda so you don't need to divide by 14.7. You just need to get it in a % that you can multiply the fuel table by., below is the formula I...

Hi Rudy,
I have a 99 Durango JTEC with a 5.9 that is stroked to a 410. My tables are similar. I would go ahead and dial in the fuel tables with the 24 lb injectors. Once you get your 30's it...

anybody know what these tables do? What are the units?109652

Just replied to your other post, After thinking about it if your fuel tables were dialed in before changing fuel injectors it does make sense to set up a fuel error histogram and change the injector...

I may be misunderstanding but I think I can help you log lambda with your Wide band afr. Under math parameters go to math user and select a user math 1, select new EQ ratio (sensor) which gives you...

thanks to everyone's response. I decided to get the vehicle running and start driving before it died from lean. Once I got of idle the stft's worked in controlling 1 lambda. After driving for...

Just verified that I sent the correct scan. The charts below show
I tried to send a snip of the chart but not working, Anyhow the upper line chart is plotting rpm, lambda, O2 volts and speed. The...

Thanks for the reply. you are correct it is taking away fuel, but why? the O2 sensor is telling the computer it is lean, the wide band is showing lean, why is the PCM taking out fuel? I spent...

Guys please help, I think this would be good learning for a lot of people and I know someone probably has some insight. If you look at the scan the O2 sensor is reading lean yet the pcm is pulling...

I have been tuning a 99 dodge durango jtec 410 stroker and have the following issues. I have spent countless hours dialing in the fuel maps and have the vehicle running nearly perfect. I then set...
