HI all
for those of you who have bigger injectors and are worried about fitting them i must say its real simple on the S2. there are many previous posts on how to do it so i wont teach you to suck eggs but it took about 30 minutes to do the swap.
I wrote a map prior to the change for the vems working out the req fuel to 4.9ms (siemmens 60lb) i lowered the cold pulse width and the hot pulse width. the target settings are usually around 85% of the req fuel for cold and around 25-30 for hot. ive found the audi wont start on these and more like 150% for cold and 60% for hot is best on my car. car started and idled fine after 1 change. i have since taken fuel out of the accel and the VE table as the injectors react so much faster.
the car feels great. it pulls strong and the juice doesn't drop off. butt dyno tells me 400hp at 1.28bar. the EGT figures are down and idle and catching idle is far far better
its time for a dyno visit again so
1. can somebody please tell me the name and number of the dyno we visited before christmas organised by animal mother. i want to use the same one again and cant remember.
2. what are your experiences of pulsewidths especially the cranking hot and cold.
3. anybody else seen good EGT gains from a better quality and larger injector.
cheers
