M7/8 with twisted turbo

[WyoBoy1000]

It my understanding that yellow=idle green=mid red=top or main jet yellow/blue=primary injectors, green/blue is secondary injectors and red/blue is the fuel switch point.

You need to find out who set up the kit and how it is programmed. There is no way to do it right until you know, if you can find out I can explain how it works.

On mine the red, If you go 2+red and red/blue at 7.5 it means nothing happens until your in the high throttle position and the box read 7.5% of load which is a pretty high load then it starts to add that +2 in the red zone. But they are all different so you can see why I say figure out the function.

I agree with wyo and the others. You need to come up with more top end fuel. Either by turning up fuel pressure or top end fuel box adjustment.
You should call shain and ask. He is a super guy. He will help you out.
Just remember to make small adjustments and remember where you started
in case you need to go back. Good luck. sounds like you are 1 to 1.5 points off according to your afr numbers. If you are in the 13 area be very careful that is dangerous to top ends.

This should be what yours is.

green = idle
yellow= throttle up
red = WOT
Y/B= kicks in secondary injectors after 9lbs of boost.
G/B= kick in on boost
R/B= kick in the red where you set it.

You don't need the red to get close it is more of a fine tune,

try raising the fuel pressure but I would check gauge and see if its right and check to see if the guage is rising. The pure logic is used for OVS kits??? what turbo are you running. I still don't know how the percentages are programmed for these numbers so its all about understanding the box and testing it.

If I understand what Travis taught me about my pure logic box, you have that correct except the red. The red(and red/blue) only works below boost, so essentially it's not needed on a boosted sled. I have turned it off and only used the other four during my initial tuning. Later I used it to add a bit more fuel for a cleaner transition to boost, once the box sees boost the red is out of the picture.

If you can't get enough fuel with the yellow blue, kind of high(6-8) and the green blue about mid(4-6) then you may have a fuel supply problem. Another thought: if you are only running a 1:1 regulator and your PL box is programmed for a 2:1 it may need to be reflashed.

Hope this helps and good luck!

Well what you are saying makes since, I turned my red all the way up expecting it to flood out my sled and it didn't seem to have much if any effect on the sled??
