Individual cylinder timing

Unread post by VJordan »

Is it possible to do individual cylinder timing on cvaf1 ? At least for cylinders 7&8 on a 4.6 . If so what scalar would it be?

I checked those and somehow cyl9 was -3 and cyl8 was -0.25
So I made cyl8 -3 also and it just backfires like crazy out the exhaust if I put it back to -0.25 it’s fine

It’s the same bin I’ve been running for the past year or so ,
I tried the newest one you posted but the car wouldn’t stay running and I didn’t have the time to find why so I switched back to the bin it’s been on

You learn nothing if you don't figure out why something doesn't work when it should.

I’m going to try it again and see why it wouldn’t run I just didn’t have the time at that moment that’s why I switched back

Is it possible for the fuel pump to be getting maxed even the duty cycle says .43 which is about 86 percent ? I can’t get the fuel pressure to follow 40 I’ve played with the pids , I halved them at first but I don’t really know what to do with them just been trying different settings . When rolling into the throttle fuel pressure shoots up then drops to about mid 20s the afr stays fine though because of the compensation so I haven’t worried about it too much but would rather not have the pressure so low

the fuel pressure histogram shows you exactly what it needs to be

just simply take the corrections tunerpro gives you and apply them

fuel pres sure be solid as a rock then
