Injection angle
Posted: Wed Feb 21, 2018 1:16 am
Hi Guys
Has anybody tried fiddling around with the injection firing angle degrees. The car has been dynoed, made 350bhp on pump fuel which is enough for what i need. What i noticed is that it is using much more fuel , apart from the over run fuel, i was looking into other things that could use alot of more fuel.
Infact i locked the fuel and timing on idle at around 950rpm, and took some readings for different injection firing angles. the best result was at -90 . Lambda fell by 0.4, this shows more fuel being burnt. It also corrected a throttle response issue that i had and couldn't fix with the fuel pump%.
The problem is that this is at idle.
I don't know how i can work out the rest of the map.
Any help even with a std map would be very helpful.
Thanks and regards
