Recently switched to V3 SD, trying to get the tune dialed in and cant seem to get my #s to make sense. I posted this on Link and didnt get much for feedback, so thought Id try here.
My OpenLoopMaxOct is tuned down to 8.0 A/F (max) and I was still running lean!
I 'added' in the fuel sliders and now am a bit on the rich side (will be correcting our next dry day).
Almost looks like the fuel pump isnt carrying its end?
Heres what I have and have done:
2.0L, 8.3:1 wiseco, kelford 280s, 93 Oct + methanol
a1000 pump (low miles)
AFPR (43.5 base, verified that it goes down with vacuum and rises ~1:1 with boost with engine off + pump on via link)
1350 injectors (second hand with supposedly low miles, checked for clean filter baskets)
Boost leaks = Couple small ones
Got a decent idle/cruising tune; global -69.5, deadtime 610.
Sending the injectors for cleaning seems possibly fruitful?
If anybody has a good idea, let me know!
Thanks
