In relation to 1993 LT1 tuning, is it uncommon to see large % increases under the Power Enrichment tables. Anywhere between 15-20% at higher rpms?

In 94-97 tunes, I notice that these part of the tables are actually lower than stock .bin files, (leaning of the fuel curve), however is this because the MAF sensor compensates because of its ability to see airflow? Cam=More Aifflow=More Fuel. Tuners tend to lean because the stock program tends to be rich.

Am I correct to assume the Speed Density set-ups have no idea of increased airflow through more aggressive cams and are limited to programming as set by the tuner. It can not compensate for cam changes to any degree (other than change to Kpa).

I ask, because my tune has around 15-18% fuel increase on the PE tables (top range) and an additional 7% on the VE TABLES @95 & 100 Kpa @ 3,500+ RPM.

Wondering if this is rational. I think it is, just need reassurement.

 

anyone?

 

You might try posting this in the Computer Diagnostics & Programming section of this board, you'll probably get much more response


Eh...nevermind, looks like a mod already moved it for you
