Async Accel vs RPM Adder ? at address 38d0

i see it here. values are

27
5
0
0
0
6
10
10
16
20
26
32

so you changed the 0's and it resolved it without the open loop and mapping or did you still have to do the mapping?

i have asynch_accel_vsrpm

address is 32e4

left side is rpm
500
1000
1500
2000
2500
3000
3500
4000
4500

then right side

might make 500 0 again lol

 

nvm fail, it didn't work i am really lost what else to adjust. atleast boost is doing better, i am just down to fine tuning.

 

Maybe you should just bump the VE up when the load is over idle kpa for the lower rpm. It could be that the lower VE is just too lean for the car. You could test it by bogging the car at super low rpm to get a reading of what the VE should be at those kpa values.

 

i will try but i don't think thats it cause even when the car was running super rich it still did the same thing, also i think i am still a bit rich because in forced open loop it was running a bit richer than in closed loop.

 

hey i got an interesting question, my car seems to do this since i went SD on occasion when going idle. https://www.evolutionm.net/forums/ec...eird-stft.html

 

dips below like it wants to stall? guy i was tuning on sd with the evo 7 had that issue when i had the map ve scaled wrong

 

Been away for several days so sorry for the late response. Okay so even the RAM SD map and regular SD map must be the same too? Suprised at how far off they are from eachother to begin with. Ive looked into LiveMap but Im not sure my ROM has it.

I know I need the correct scaling for the map sensor but I thought when I went through every map sensor related table and changed the settings from omni 4 bar to klavico 3.5 it would be set. Do I need to find the scalings and manualy put them into the SD tables for the other tables to actually save as 3.5 and not 4?

The problem is Ive opened up the original rom that I downloaded and the settings are all the same. When I go into the tables and change all the 4 bars to the klavico 3.5, those numbers never changed. As I asked above, do I need to manually put those numbers in?

Thanks for your responses!

 

dont tell me that! back to ve tuning i go , i think i need a good explanation on how to correctly use map trace then. cause i think that is messing me up.

 

Nothing changes when you change scaling absolutely nothing.

Scaling is a formula it just coverts number A into number B thats it. In the rom that number is still the same as it always was it just the display in the ECUflash program differently. For example when you switch it out from 4 bar to 3.5 bar you'll see a lot of negative kPa numbers because the numbers behind are the same.

The numbers behind the scene are volts so YES you MUST change them for it to be right. I think i've stated this a couple times already to start simply copy the right hand side into the left and begin tuning.

 

Skyline send me a log of your issues I think you have my email already

 

well i just got done running around with the maf to do some logs to reference the SD logs so i'll send that with the SD log

 

Ok so a couple things are happening to you.

First what you really need to do is stop single point editing maps. If you view you map with graphing it looks like star wars canyon so you're fueling is going everywhere. Try to be smooth in your changes always have graphing enabled when your mapping changes VE is smooth and it changes smoothly. I changed the general trend of your VE so its smooth again and emailed you.

Secondly the o2 sensor trim is screwing you up. The o2 sensor trim just isn't fast enough to compensate for a barely tuned SD map. When your beginning like this you need to look at what the map is doing and not what the fuel sensor is doing to your map some time later. The best way to open loop is to change the open loop load and i'm including that change with your rom. Your async changes may need to go near default to really have the best effect.

Tips:
Since your really starting from scratch like I did I think it will be best to make changes in the beginning solely to the kPA vs load% table (2d one). This is a broad change to all the fuel and it will help you center the fuel and VE map for fine tuning later on. Once you have the kpa vs load down to where only quarkyness remains, ie stomp the throttle and slight lean or letting off the throttle a little rich in certain RPM areas its time to focus on the VE map.
