was just wondering can you get both the low throttle and hi throttle maps to work on a ep91 manual as far as i understand the manual is just a open and closed circuit on the throttle position sensor but i have a automictic throttle body lying about is there anyway i could make that work?

cheers for any help or input

Safc2 has low , average of high and low and high maps set by rpms.
You set low rpm and it fuels the low map below this. You set the high map rpm it fuels high map above this. In between it averages the maps.

The TPS has idle , part throttle and wot. You basically map them to work together.
eg I have set the safc2 to 7600rpm and my low map is 30% x 7600rpm this means it changes map at 2280rpm.
For my setup I go on boost usually at 2000-2200 so the ecu goes into open loop and the safc2 also changes map.
The low map prior to that is used and can be tuned for spool. The part throttle map also has to work for cruising
especially in OD .
