Maxed out maf table at 67lbs?!?!

[Frosty]

So on my setup I already scaled the 60lb injectors back 30% for e85 and I have a ls2 maf. Im hitting aprox 10,875hz on the table occasionally so I dont need a maf scaler yet. Tuning has gone well so far and I have everything below 7500hz locked in at 2% or less. My issues are with 7500hz+ because im maxing out the table at 67ish lbs. Im guessing taking the injectors down another 20% and then taking the maf table down another 20% will take care of it but I just wanted to make sure.

Something is wrong. You should be able to use a stock LS2 maf table, which doesnt even pretend to max out. If you are tuning the maf at all there is a mechanical issue, I have never needed to tune a LQ4, LT1, or a stock maf car's maf table before.

When I switched from stock maf which was nearly perfect to ls2 maf and table everything was off by 15+ percent wideband and narrowband. No way just changing the maf caused my entire fuel system to shift 15%.

Figure out whats wrong then. I usually just start with a stock tune, then dial the injectors in where they need to be on a stock maf table.

You've got issues. No way your MAF table is even close to correct. Go back to your stock table, and check everything over.

All i did was scale injectors down 30%... Idk where i could have messed up

 

[darkhorizon]

scaled injectors, then your maf table magically added 50%?

I changed maf table after scaling. Ill mess with the tune and zzp fpr tomorrow
