LTFT Q for 06MonteSS

[rv85]

This is dbaker from the CF.02Z06 Corvette with VR + Power Duct + Halltech Honeycomb MAF screen.No other Mods.

Just did 2 ,30 mile data collection runs using the older model(2.13),no logs.First run was at approx 40degrees at 58mph:Both LTFT's ranged from 15-23 and on a flat surface was 21 & 17.Map ranged 5.7-6.3.

Coming back,it was about 60 degrees at 58 mph.LTFT's had same range,but mostly stayed at 21 & 20.Map at 6.5.

Any adjustment suggestions?

Thanks

your ltft's were up at +21 and +20????? daaaaamn...

any exhaust leaks anywhere?? any intake leaks anywhere?? make sure everything is TIGHT so no extra air is being allowed in anywhere...

your ltft's shouldn't be that high...

Nope,all tight and taped at the connecting points to avoid air leaks.

After I installed the VR Power Duct,I was popping lean codes fairly often.The Halltech screen eliminated the codes and made the throttle res better.

Car runs great...good power and mileage is decent.

Any suggested adjustments? The STFT's varied from -3 to +3 on the hwy.

go -15% on your injector slope setting...

put on about 150 miles, and then do a new steady drive/cruise and see how the ltft's look...

you wanna cruise at about 1800-2000 rpms....

Thanks & Done.

On a 40 mile interstate trip today( 75mph/1900rpm),the first 5 miles were
(T)+4.69 and (B)+2.34.After about 15 miles,both settled on +3.91

Am I getting close ?

Thanks for ALL your help!

Subtract another 4% and that will get you right where you want to be. Then make manother run and see where they settle out.

[rv85]
