JB4 Logging, stacking and Map 6 Discussion

first log of map 2 with is38 on with e30

map2 quite safe. try 7psi from 4500+

 

[Bee_Finn]

I normally have been doing absolute values on map 6 when is20. What values would be 4500- ?

If you are set on doing map 6 as an absolute still you can find that answer by taking the target shown on that log you posted at each rpm point and subtract that from 7 then take that difference and add it to the boost value you were hitting at that same rpm point.

example:
4500 rpms
Target - 4.5
Diggs suggested target - 7
4500 boost - 23.5 to 24.5
7-4.5=2.5+24=26.5 @4500 (just round down to 26 to be safe till you log)

Hopefully this log show the fuel bias changed here is another 3rd gear log map 1 e30

Looks good I peeked your long multiple pull log aswell that had some cyl3 timing pull on boost onset, raise boost safety to 28 and log map3. Do you have any mods?

@ChrisMk77 I have drop in k&n drop in filter gfb diverter valve catless dp intercooler intake tube turbo muff delete turbo inlet pipe

 

[Mrpie187]

I'll move over to map 3 and do a couple logs today thanks for all the help guys

 

[Diggs24]

turn it up

 

[Mrpie187]

turn it up

@Diggs24 I've been waiting to c that lmao should I still b at 60 fol or go to 50 with e30

 

[Diggs24]

60

Looks very good so far. Like Chris has mentioned, do boost safety to 27 or 28. Make sure to change the 6-cyl timing to 1. It removes the safety nannies that intervene when ya turn things up. Have to see if the AFR spikes lean again around 4500. Map 3 should be a walk in the park.

is JB4 code 49F5 "O2 B1S2 Stuck lean" just due to catless downpipe? Is this a code i can just ignore? I have a spacer on it as well.

yeah S2 is sensor 2 so that's the downstream post cat location, which spacer and insert are you using in it?
