I can't lean it out

[isaac]

it doesn't matter what i do, I can't lean it out. and if I put it in gear, it will go lean instantly and tries to die.

reduce Engine>Fuel>Transient>Tansient Fuel Qualifications>Min Fuel Milligrams from .029 to .019. Will further reduce the min injector pulse width floor and lean out your idle. Check your IPW before and after....Larger injectors can't be driven low enough with the stock settings.

So waht you mean is that all my injector data is wrong?

[mowton]

No, believe them to be 80lb Deka's or equivalents. In order to get a small enough pulsewidth, you have to further reduce the pcm hard limit or else you ar spaying rich at idle and no matter how much you lean it out, you'll never get it right.

Don't know enough about the injectors or their heritage to respond to the accuracy of the data, but with the IFR values you have, you need a decreased min idle pulsewidth.

this is my setup: it's a 1986 rx7 swaped with a gen 3, 5.3, 224/224 .581 .581 cam and 625 springs 78mm turbo 80lb Siemens injectors @58psi dual 255 fuel pumps turbo 400 transmission 01 ecu 3 bar gm sensor and all that stuff to run speed density, I'm not running o2 sensors but I do have a AEM wideband

[isaac]

I have another question why when I log in can't see any data from pulsewith?

Did you select the two (Bank 1 and 2) Inj pulsewidth parameters in the Channel table as well as in the Chart? You may have to hookup to vehicle to collect the parameters supported first. Assume you already have though...

Is the underlined a problem?

Honestly I'm not sure, but somebody told me on another forum that if I'm running a GM ECU then I have to run o2 sensors or I won't be able to tune it. But he wasn't really sure about it. I appreciate your help. I just feel like on my settings that I must have missed something or something is wrong.

[mowton]

What is the problem then????????

Ed M

[isaac]

The problem is that I can't get it to lean out on idle and when I put it in gear, it leans out. I did what u told me to do and IPW before the adjustment was 2.1 and now it's 2.0 and it did lean out a little but not enough. I just want to know if i should keep lowering that number until I get to where I need to be?

I was asking if not having O2 sensors was his tuning problem.

[isaac]

Oh lol, he was just assuming that that can be the problem but he wasn't sure

Yes, try .015 now....

Sir u are the man, it's working now the way it's supposed to

My pleasure...glad you got it sorted out

I have another one for you I wach ur video on YouTube about virtual ve and I was trying to find out why when I go to Edit it don't have that virtual ve option?

[5FDP]

Because VVE is a GEN 4/GEN 5 computer thing only.

GEN 3 computers use regular Primary VE tables. You have a gen 3 computer.

Gen III's have a conventional VE table in Airflow tab....only Gen IV/V (E38, E67, E92 etc) employ virtual VE.
