chugging 4agze *with video*

[30psi 4agte]

looks like your fuel pressure is way to low reece.

It should be up around 35 psi on a stock 4age ( about 240 Kpa )

sure that reading is in KPA ???


aaaaahhhhhhhhhhhhhhh beaten !!!!!!!!

[reecegze]

ok guys seems that i am slowly breaking it down ... Yes it is in kpa ,but on the dial it only said pressure so i am assuming its fuel pressure as its on a fuel map recording ... Now if i figure out how to send this jpeg screen shot over to my laptop to my hone pc i post it up and see if you guys can get a picture of what going on

For now ill just take a picture and host it

[reecegze]

Take a look guys - thats for my fuel map

dont stress its manifold pressure not fuel pressure !

I didnt think EMS logged fuel pressure.

It will pay to get a gauge from somewhere and check your pressures though.

[reecegze]

dam i hoped it was fuel pressure , that way i can fix it with the new fuel pump
well my theories have gone now , i got nothing left
is that a normal manifold pressure ?

[reecegze]

so all of those reading are about right ?? as these reading are from when i chug alot

[30psi 4agte]

do you have staged inj turned on ??

[reecegze]

this is the map the tuner has setup so i havent touched anything just recorded stats
should it be turned on ?

[reecegze]

A/f = 14.40 is that an lean or rich mixutre ? at 2500rpm
i get about 12.5 a/f on idle

[reecegze]

just created a data log to check the variables on a/f its on around 13.5 on idle warm then soon as i accellerate it goes to as high as 16 a/f is high the figure meaning getting very lean ?

[slide86]

16 is very high and getting into detonation territory. i would steer clear of that.

i still think its your fuel pump

sorry for sounding nooby but 16 a/f? doesnt that mean leaning ??? all i know about detonation is that its caused from to much fuel entering the chamber and not being burnt smoothly like it should it detonates causing car to ping.

could it be possible that my knock sensor is fucked ? causing my car to retard timing not on idle but while driving and making my car run like shit

reece i think you better do a little more reading

[reecegze]

honestly mate i dont know shit about this car i bought it like this there plugs missing everywhere due to this aftermarket setup , i payed 400 $ for the tune and i dont wanna go back there abusing him for no reason if he tells me it wasnt his side. I appreciated people helping me because i aint no car mechanic.

could someone just tell me how these a/f mixtures work, so i can find out if my fuel pump is making me run lean

[kingmick]

well said and ill give you rep for that because its the right way to think! when you play aftermarket there is no warranty.
id love to help but without hearing it and seeing it is very hard to tell whats wrong!
if it is logged as fuel pressure its the pump etc, if its not fuel pressure logged its a air leak in the system exept if its a mapping prob! as you see there can be a few thing it can be
