VE Table Question

Unread postby Mikestang » Thu Jul 18, 2019 10:26 pm

When tuning the VE table, what if it requires a larger VE than 99.61 (the limit for the table)?

My car is NA, This is theoretical at this point...

kick up the ve multiplier scalar and reduce the ve table accordingly

or reduce the injector slopes and VE accordingly

Humm, not finding any type of VE Multiplier in my DA1.

Not sure I will run into this issue yet. I just started some initial tuning and already have pretty high VE numbers in the table, around 93. These are stock 19lb injectors, I have not changed any of the injector data.

Injectors are too small. With the combo in your sig 30lbers would be my minimum.

Vehicle #2, This is a stock 302, stock E6SE heads, Stock TB, Stock Upper and Lower intake, Ford F Cam, Long tube headers. I'm am also at high altitude in CO. I guess they may be close? Numbers in VE table seemed quite high for no load at 3000 rpm. I initially thought my fuel pressure may be off, (gauge in car), but I verified it is correct.

Found a "Airmass Flow Multiplier" KVEFF, would this be what you are talking about?

This came up in a search, from what I gather when I change heads, cam and intake I'll need to modify the to work with the increased airflow. Is there a formula or a multiplier if I know the airflow capability of the old heads vs. the new?

What happens if I were to only modify the top right value of the VE table, say moving it from 85 to 95?

cam moves tq so some colns values will all go down and some columns values will all go up

heads changes the whole table. Only way to dial it in is to hold each cell and plug in the fuel error.

95/85== 1.11

you made it 11% richer there.
