End of Injection Timing Open Discussion

[WASyL]

I've got the 60123 from lunati 243/251 110lsa. What I'm wondering is why not spray right in to open intake but wait until the exhaust is closed closed enough

actully this is what You want to do, the later EOIT happens the later PCM starts to spray. The more EVC the less unburnt fuel is evacuated thru exhaust and by that engine works more efficient. This also reduces fuel smell on idle/cruise on engines with big overlap cams and helps witd drivebality

also found this on HPTuners board for LS1 PCM but actually it apply to any fuel injected engine:

- By adjusting (increasing) EOIT "Normal" , you can reduce or eliminate most exhaust smell at idle when not running cats on a cammed LS1
- LS1 PCMs are limited on what you can control, not 1 value solves all
- .11 = 10 degrees of crank rotation
- Leave the "Injection Timing Boundary" at 6.50 (stock value)
- Leave the "Makeup Injection vs ECT" at (stock values)
- Don't oversize your injectors for your application
- The bigger the cam and more overlap the higher the "Normal Injecting Timing vs ECT" values
- EOIT normal values can range from 6.0 all the way up to 6.5, depending on valve events

Now I'm confused your saying we need to add to the eiot ? Not re move. I don't have hp tuners I'm using eehack so I'm guessing the eiot definitions are different on how they are displayed I don't see a normal or injection timeing boundary in eehack only the eiot vs temp
