ECMlink Can't get car to lean out. Log inside!

[maneotis4g63t]

Good afternoon.

So we went out to do some tuning and we are running into a peculiar problem. We keep leaning out the max octane table in the higher loads, but at WOT and at about 4000 rpm's it goes pig rich to 10:1 on the wideband. The car sputters and coughs because it's too rich. Should I just keep pulling fuel to see if something helps? I'm getting a few counts of knock, but I don't know if it's because I'm running so rich.

GM Maf
1000 CC injectors
Walboro 255
Borg Warner s366

If anyone could help with any advice that'd be great!

Your log says you have 922cc injectors and do you have a AFPR?

If its still rich, use the Maf sliders at the hertz your at to lean it out.

Did you post an idle log? If so post a WOT log

Injectors say 913cc, but your sig on here says 1000cc (fix that)
What was the knock count? If the knock count is bad enough ecu will use MinOctaneFuel table, which are set to pig rich in your tune.

Sorry guys, use this log instead.
Well, I had no idea about the injectors. I do have 1000's so I'll check it out.

I was getting like 5-6 counts of knock in the upper RPMs. Also, when I use antilag it goes super rich in the upper RPM's.

Get the injectors right, then use the maf comp sliders to adjust AF ratio.

What are your Global Fuel and Deadtime at? The global will definitely make you run very rich if you aren't taking out enough

Your boostest is 39psi. I would start from the beginning. Boost leak check, dial in global fuel, dial in MAF.

$hit it says you have 1377 Injectors!!! ... So many experts... Look at the % of fuel removed not a abertay number.



PTE "1000cc" Injectors flow about 940cc at 43psi. Can't think of anyone else that calls them 1000's...

97% duty and flowing 67lbs a min... You Running 36+ PSI? No, didn't think so.

Like said above Boost leak test.

Oh,
Read this as well OP... . CLICK
