LTFT moving in open loop (O2 unplugged)??

So I played with low pulse width - injector offset vs map table and got the pulse width lower.. it seems to help a lot.. I do have a question with dhp.. I thought in the IFR table if you wanted to be richer you decreased the IFR table but when I made the whole table larger it got richer.. doesn't make sense if the tavle in DHP is msec/gram

Yeah I've been playing around with it and have actually got things pretty good...

Does anyone have a stock NA IFR table.. I'm curious to see if it goes from 0--100 without the-10 thru-50.

I've been told that the table is actually atmospheric pressure-map. Which would put 150map at-50ish.. At least around here.. I know when I put a really large number in only one cell (60 - which would be my idle point 99.4-40map) the thing got really rich right at the 40 map mark but was fine everywhere else so I'd say there might be some truth to what I was told..

the table is actually in manifold vacuum.

so if your MAP reads 30 kPa, baro was 100 kPa, manifold vacuum is 70 kPa.

NA IFR table is one value all across the board. Because the fuel pressure regulator does its job as does the fuel pump. Pressure changes at a 1:1 ratio with manifold pressure, keeping injector flow rate the same.
 
Wow, Leaned the car out a little tonight While In PE on E85 and added a little more WOT tuning.... This thing runs pretty good.. I really wanna get it to the track to see what it MilePerHours..
