hot start problem
Posted: 2021 Jul 03, 14:10
I'm struggling with a hot start problem. I have 160lb FID injectors, but the following items have been scaled in half: maf transfer, cid, injector slopes and injector break point. I did not scale the FN367 injector offset versus voltage, not sure if I should have or not? The car starts fine when the ECT is less than 170ish deg. When its closer to 185-190+, it doesn't do anything but turn over (doenst light off even a little). If I wait a few minutes and let it cool down some, it will fire right up. I have messed around a lot with the FN348A Cranking Fuel PW vs ECT table. Is there some other reason why the engine wont crank when its hot?
65534......0.598 <-
200.........0.598 <- I have moved the top two PW values everywhere from 0.43, 0.45, 0.50, 0.55, 0.60, 0.65, 0.70
150.........0.598
70...........0.702
40...........0.952
20...........1.465
0.............2.075
-20..........3.455
-65536......3.455
-65536......2.881
-65536......2.881
I've even tried going lower than .43 on the top two rows , but it didnt work either. The data I received from FID says that the min inj time is .43 seconds. Base timing has been verified at 10deg with the spout unplugged.
