so i got a wideband last week, installed with no probs. got the o-meter too so i can street tune the thing.

my settings from the afc when it was on the dyno.
lo 98, hi 99. hi/lo settings were the same throughout
1-3.5k -40
4k -37
4.5-8k -35
also had fuel pressure at around 42psi. had to adjust tps so it didnt kinda hunt on idle, idle kept dropping down to about 450rpm then up to about 1200

since the wideband got here i have sorted the afc finally. the afr on idle was about 17:1

street tuned afc settings,
lo 10,
1k -32
2k -41
3k -42
4k -42
5k -35
6k -35
7k -35
8k -35
hi 50
1k -44
2k -48
3k -46
4k -38
5k -33
6k -33
7k -31
8k -31

i now have idle afr of 13.6-15:1. set the tps and removed the adjustable fpr in favour of the stock fpr, now idles petty smooth.
at wot i got 11.9:1 afr from about 3k up to about 6k, then the boost creeps
i was having a boost creep problem a little while after i changed the head gasket, so i took out the mbc so i was runnin off wg spring pressure, its a yellow spring, this is 3.6psi right?
so i had about 4psi till about 6k then creeps to around 10-12psi.i changed the feed to the wg from the plenum to the compressor housing. still creeps around 6000rpm. checked the diaphragm in the wg, it looks fine.

gotta see if i can get some dyno time, sure that curve will look a bit a bit less like walters now lol

45psi

good job on a hmt setup yo
