Speed Density Idle problem ( 70 LOAD- 10.5 AFR )
 
Hello Guys,
After 5 days my Evo 8 with speed density running!
Car running at idle with 70 LOAD(95Hz airflow) instead 30, and 10.5 AFR instead stoich.

What's wrong? Seems needs a sort of calibration MAP -> LOAD ?

Thanks :)

maf load = sd load, check you calibration

This is my sd ve table.

Any suggestions?

Thanks :)

I am not a professional nor a tuner, although your RPM VE seems a bit rich on the idle.

Just noticed that you said after 5 days like this was a problem that just came up after 5 days of running differently on the same tune? If that occurred you might have a mechanical issue.

Try RPM VE 500 to 2000 as 64, 67, 70, 75, 80 and see if that leans it out any.

I was trying to edit posts because reading replies you made right as I posted so messed the order of posts up a bit.

Thanks a lot!! I will try! :)

EvilEvolution8 May 10, 2016 12:05 PM

In your opinion...the rest of RPM VE and the MAP VE is correct ?

ridenrunwv May 10, 2016 12:07 PM

Can't really tell just by looking at that. You could honestly have all different variations of data in tables and the car still run fine.

EvilEvolution8 May 10, 2016 12:10 PM

Ok perfect! :)

Bump
 
im having a similar issue with my load, it's 44% at idle and the car uses mid LTFT at idle and sometimes goes to low, any ideas? Did raising your RPM ve tables a bit help as suggested?

Need to change the crossover points for your fuel trims. It shouldn't go to mid until like 55-60 load.
