Mivec 4G93 - feeling of impact (hesitate/sag) when decelerating. PLS HELP!!

0.5v is ok then right?
Should i need to calibrate again?

If you still having the jerking, try calibrate again to different setting then try again...I think you need to trial and error also....

i cant remember it correctly..
but if u can..
at close adjust it closest to 0.5v
at full open closest 5v

 

[^pomen_GTR^]

set wot at highest 5v first...then check lowest value....

test drive... if not set 0.3v (or lowest possible) then compare at WOT if it gave 5v to make sure there is no performance loss

i have check the voltage for the tps,
throttle close-0.5v, throttle open-4.9+v
is it ok?

should be ok....or try slightly lower max value around 4.7v

If i lower the max value, the throttle closed value will reduce right?

 

[vr2turbo]

If i lower the max value, the throttle closed value will reduce right?

Since you are still having the problem, no harm trying or testing different settings....

coasting setting? but ecu is stock right?

hmmm, what cause engine braking...too much...

Yes…stock ecu

What's the range for the tps value?

 

[vr2turbo]

As per bro. pomen post.....

 

[kayour]

so...how?...dh try??
or...maybe the problem not from tps

 

[.:JiT_187:.]

adjusted to 0.4v when closed
same also..sigh~

Looks like not TPS problem then, have to look else where......

 

[kayour]

can be ecu...plug coil...power tr unit...

 

[^pomen_GTR^]

or worst case...ecu internal capacitor leaks....

but there is plenty of ecu guys can do replacement on that capacitor....

Technician also can fix if really capacitor problem. Take out and replace with same unit....

for hardcore DIY fan sure can

Yup, because is repair PCB board not actually car repair......hhahahhahah

 

[.:JiT_187:.]

I've interchange the ecu before..
The problem still remain
