This means you can change the stock narrowband of the car with a wideband sensor and using the patch you can set the afr to whatever you want?
Or just using the patch?
I try also to lean my car at idle but i cannot because of narrowband sensor and i do not know how to solve this problem. I am also using 96530006 with some tephra mods.
Please give me your help.

 

Please somebody help..

 

Wideband gets wired into the ecu by rear o2 pin. Place the sensor anywhere you want. Enable patch and tune cl afr.

One better

 

I'm currently having cold start issues I have buschur bf 272's so I'm sure that could be a cold start issue adder. Also know I have to keep my foot on the gas for like a solid minute or the car will stall I tried adjusting the biss screw on tb and I didn't even see the idle raise and the afr was going real to the point the aem wideband was showing - - -. Car sounds like a chugging train or a misfire maybe due to lack of fuel at the idle once the car is able to idle on it's own. Any ideas of what can help or it sound like all tuning?

 

Yes your tuner can easily fix this, or you can fix it yourself.

If you are on E85, once you get below 50 deg F, you need a lot more fuel than you would think during the warm up phase. This is because ethanol doesn't evaporate as well as gasoline at lower temps and so it is much harder to light with a spark.

It sounds like you can get it started but it runs super lean while it is warming up. Try adding fuel using the MAF Comp for (coolant) Temp tables. Increase the values at the coolant temperatures you see before you start up by 5%. Keep increasing 5% at a time until you have an AFR of 12-13 after start up.

 

Thank you very much!!

 

Thanks a lot!!

 

Now does that work the same if my car is speed density? I don't have the actual maf on the intake.

 

I have installed JUN 264 cams the idle is loopy, i have changed the hi and low octane maps changed to as rich i can get but the ecu still hunts for 14.7 but just at the starting 5 secs it hits 13.5 and after that 14.7 - 16.

Every one on the forum is saying i should advance the timing till 12 degrees but infact what i have noticed the car is lacking fuel in the idle area. Advancing the timing the car cranks late and raising the limit the water temps climb fast at idle.

I NEED TO RUN 13.5 AFR at idle [ with out wiring the wide band sensor with ecu. not good at electronics ]. Which table should i fiddle with to achieve the desired... The rom is 93360005.

Require assistance please.

 

Have you let the car sit and idle for 20 minutes to set fuel trims?

 

Not 20 but 15 minutes.

If i change the values 500 - 1000 rpm cells of open loop load # 1 and #2 to -9.5
So the open loop will operate for these rpm ranges above -9.5 load ?

Similarly if i change the throttle low and hi load 500 - 1000 rpm cells to 0 from 1.62 will this bring in the open loop for that rpm range ? or on the load 1 and 2 tables will do the job?

What temp should i put in for min coolant temp for closed loop ?

Which condition does the ecu responds to first ? the load tables or the min temp ?
