Use spare tps for fuel trim?
Posted: Mon Feb 19, 2018 12:27 pm
As I have a spare tps, could i use this as a quick and dirty fuel trim control, wired via an analogue in? I want to dial in a fuel map for different sized injectors and fuel pressure? I have calculated a % change due to these changes, but was thinking of giving myself +/- 5% to play with to get the afr back to where it needs to be if the maths is wrong.
If the logic is sound, can you define the cells you trim in the software or is it global. I know i could do this in mapping, but a single rotary i can adjust on the fly would be useful to avoid having the laptop in the car.
