Now I see why some don't post here anymore.

Interesting..... The AFR500 uses the same harness and wideband sensor as the AFX powerdex. I was told that the AFX powerdex and AFR500 are the same units just rebranded for copyright reasons(its...
This^^^^. I ended up just getting a new harness and kept my AFX box. I had another sensor that was still under warranty and I swapped it out.
Nevermind, I got a clarification.......................
This sucks, I was out tuning and accidentally burned the connectors were the wideband sensor and harness connect with my AFX powerdex/NTK unit. They melted together. So now I m basically gonna...
I just went back and read what you said, these statements are contradictory.
Explain how did you tune those other many setups in open loop?
I don't cosign with taking short cuts but if you must, get a wide band or use a wideband. Or else it will just keep dumping fuel. Then you will have more problems to deal with.
Not...
Post your tune and log if you want thorough advice.
You need a wide band in order to tune WOT properly.
You should NOT be tuning WOT with your narrowbands period.
I am waist deep now. lol
I usually do not run into an issue like this or have to increase the proportional to oscillate faster with a stock motor with all stock parts. Beats me.
The O2's are in the stock location of the...
When the B2 O2 harness plug was on the drivers side wrong, we got P0171(bank 1 lean, the drivers side). We swapped the B2 O2 harness to the correct side, the passenger side and now we are getting...
I swapped sides and it works. The only problem now is the O2 is reading lazy or dead at idle but switches well under rpm. I ohm'd 2 different AC delco O2's and they both ohm's fine at 15. I...
I have to download the wiring manual off painless. This is the times when tuning is a pain. I m one of the few tuners that will actually do some wiring investigation or wrenching around here. ...
I had a conversion car come in that is a bit of trouble. Maybe you guys can see something I don't or confirm.
Here is the info on the car-
79 Malibu
All Stock 5.3 from a 2005 Silverado...
It is a good idea to log AFR commanded and AFR error so you can see on your logs. It will make your tuning process easier.
It is a good practice to use AFR error as well for fueling if you are...
The only way we can give you a more accurate answer we would need you to post your log when the event is occurring and post your tune.
But to take a rough guess, there are other spark modifiers...
Ok. I compared a 99 auto file vs. 99 manual file. The auto tables are different.
Go to
Engine>Fuel>Open/closed loop>closed loop proportional
*Set this table back to stock
Engine>Fuel>Open/closed loop>airflow mode
*Set this table back to stock
Try this and see if...
Great, but you still need to fix those other things mentioned in this thread asap.
I just tuned a car that had killer jerking and bucking especially when downshifting via 2>1 and cruising around 1st or 2nd.
It was pig rich with too much timing. I cleaned up the VE and made...
As stated, you need to make sure the MAF is in fail mode.
Too add, your PE/BE tables need some work. Look at your log and see that your are lean for a a couple of seconds even though your...
