Hi all.

A new question.. reading the DTT help files and checking on the 2D files is the

IAC Based TPS Adder Table... now the file states " This table consists of a throttle position factor corresponding to IAC position. In an Alpha-N fuel control, IAC position must be considered. A high IAC position (high idle air flow) is the same as opening the throttle. In general the values in this table need only be edited if an aftermarket throttle body with significantly greater air flow is used. In this case, the table values should be reduced slightly"

Now according to this the values should be changed for the throttle bodies that have the HI AIRFLOW....
Now if I remember right (per my conversation with Chris) the Gerolamy throttle body is a high flow throttle body.

My question is why then are the values the same for the stock Delphi single throttle bodies....???
And should the table be messed with?
Has anyone tried this?
It seems to me that going from a single 44 mm throttle body to a 50 mm dual throttle body one would have to change these values to represent change in the higher airflow.
I would think that if you dont change this value you would have to compensate for this somewhere else.. maybe the Delta TPS Fuel Multiplier Table... But since this table is maxed out by DTT and you cant make up for it in the Asynchronous Fuel Gain (which according to Chris is maxed out at 60 for the Gerolamy throttle body then where do you make up the difference for the lack of fuel (yep there is a lean spike when the throttle is "Blipped") when the throttle is quickly opened.
Now since I have a hesitation on throttle opening and have a lean spike this tells me that I need more fuel or less air on throttle opening and since less air is not really possible I guess it is more fuel... Right?
