Just curious if anyone has used the Narrowband of the Innovate module to replace the stock one. Im tired of fighting my tunes with closed loop and dont feel like running open loop all the time to keep it perfect or do what everyone else does and goes off narrowband until WOT.

Thoughts?

 

i dont think using the simulation wont help tune your low maf freq. either keep doing what you have been doing or get the hpt mpvi pro so you can log your wb directly and use afr error to tune all the way across the board.

 

Problem is that in closed loop your maf could be raised to whatever you want and the computer will still compensate with trims. The only way is to keep it in open loop the whole time. I get 14.7 in open loop during normal cruise but when i enable closed loop again my trims compensate me back down to the original 14.0s

Ive calibrate my wb many times and get the same results. Also i know its functioning correctly because during warmup it goes back to the original 20.5-20.9 oxygen level.

bump for advice

 

what are you trying to achieve? the fuel trims are there to compensate for small variations in a/f conditions in order to keep the car running near stoich.
if your fuel trims are trying to keep it at 14.0 then something is out of whack.

 

hence why im thinking on the WB simulated narrowband to get things in order. I dont know if the voltage/pulse is the same.

 

what im trying to say is that i doubt it will allow you to tune anything in the lower maf frequencies. its just something to keep the ecu happy in absence of a stock o2 sensor but it may not work too well on our cars. if your CL is holding 14.0 while your commanding 14.7, your factory o2 sensor might be packing up its **** and going home.

if you want to do this, you can change one of the analog outputs in the lc-1 to narrowband output by using the programmer software on your laptop. its simply a 0 to 1 volt signal. then run either the brown or yellow wire (whichever one connected to teh analog you changed) to the signal wire in your o2 harness. should be easy. its either the blue or purple wire in the bunch of 4.

 

Where is your Car's bank 1 o2 sensor in reference to your wideband location. Your car may be correcting your fuel just fine and your wideband might be in a spot that doesn't show the correct AFR.

I have this problem at the moment as well since my weapon-r header comes with an o2 bung on the primary and the collector. My fuel trims were way off of what my wideband was reading because my primary is running about 1 AFR richer than all of them together, also when your o2 sensor gets super hot it tends to read richer so my car would lean out to 16-17 AFR when i commanded 14.7.

Anyways, i swapped locations of my WB and bank 1 o2 and they work better. Whats best is to have 2 bungs right next to eachother so they are reading the same stream ofcourse.

But, using the narrowband signal from the wideband o2, that was an option i was also going to try. I say go for it and report back on how well it works. I don't see any reason it should be bad unless you wideband is in a spot where its not reading correctly.

 

my WB is at 2 oclock before the cat facing the engine. Its just above the metal bracket on the right hand side. Im still up in the air about whether it is my WB sensor or my stock sensor. Going to dyno it sometime before i determine what it is, since AFR meters at the dyno will expose what is faulty.
