Hi

My car is dumping fuel during hot crank. I´ve tweaked with Crank fuel PW vs Coolant temp-table but with no luck. The injectors have been replaced with Ford 0280150943. Is it possible that the offset vs battery voltage are different compared to the original injectors so that when the voltage drops during cranking more fuel is delivered? I don´t have the offset values but I thought that newer injectors are less dependent on voltage. I´ve found one value for offset. 0.055ms. Can I translate that to the whole table?

Current Injector PW correction vs Battery voltage is
6.4 2227.81
8.0 1861.60
9.6 1525.90
11.2 1190.20
12.8 854.50
14.4 610.36

If not, is IAC park postition next thing to try? I´ve tried to give a little gas during cranking but that has limited effect.

Cold, the enginge starts fine. Hot it cranks for a couple of seconds until it slowly fires.

try those offsets​​​​​​

keep playing with the cranking and possibly open loop fuel tables. What mask/system are you using? Iac position could help too

 

Ok. I´ll try that

I use $32b mask and are editiing the original bin.

One thing I´ve noticed is that the idle increases after a cople of minutes, My theory is that it happens when the ecm swithes to closed loop. And that rpm increases because it leans out a bit. Does that point towards open loop fuel tables? I´m a bit nervous that I make it run too lean and potentially harm the engine
