afr in other gears?

[Timing]

So is there any possible way to tune the afr vs other gears? And if not where should i have it sitting in what gear. Right now im at like 11.7 throughout second gear then when it shifts to third im seeing like 12.5. Car seems to be happy and im not really seeing any kr. Ive heard these cars like 12s anyway.

Not really, because look at how the PE is setup.

It's just based off throttle % and coolant temp really, and there is an adder table as time goes on. So you can't change it by gear.

They like 12's if your NA or maybe running E85, but I'd still keep it in the mid 11's to keep it safe.

Idk but that would meen that i need to keep the second gear in the 10s to have 3rd in the 11s.

Or set PE to a single number, zero out the adders and see if it stays around what you command.

If it goes leaner on your wideband but your commaned AFR in the scanner stays the same, then you have fueling issues.

commanded is set to 11.8:1 and all adders are set to 0.
Fuel pump is brand new and new ac delco fuel filter not long ago. I kind of wonder if one of the injectors is slacking though.

Also what do you run for a wb? I think ima invest in a NGK and sell this one.

Do you have a re-wire though?

Because after 10-15 seconds of WOT the power supply with the factory wiring can cause lower voltage to the pump.

Yes i have a rewire. So are you saying that your wb reads the same throughout all gears?

Playing with the PE adder over time table I've been able to pretty much eliminate AFR changes into 3rd (on a blower car).
It doesn't do the same thing at all with my turbo setup.
Probably because Im only in 2nd gear for 2 seconds.

Oh nice, ill look into this thankyou.

Just make it add .2 to .5ish more fuel in the spots needed and see what happens.

I run a AEM wideband in both my car and truck, works just fine. I don't do this stuff for a living nor is my car making a bajillion hp and needing a better more accurate wideband.

^what snowflake said. look into "PE.RPM. vs TIME AFR" table. I try to time it so starts to richen up approaching the 2-3 shift point from a stop . . roughly
