aem wideband

[pete.w]

just fitted me new aem gauge and alarm bells going off when putting me foot down.wideband gauge displays around 14-15 when tickover but when i give it some stick it travels to the left and goes straight down to 11 (the lowest reading). ive read this shows its dangerously lean and need some advice of where to start the corrections. ive looked at my injecters and there a purple colour (what cc are these ?).
here is a list of my running gear

2jzgte twin (MKIII)
3" straight exhaust
fuel cut
blitz induction
alloy rad
walbro pump
apexi boost controler (set to 0) until sorted
front mount intercooler
running on mk4 ecu

any help please pips as i dont want to blow her up (fingers crossed)

Well for starters 11's is running rich and when in boost that is completely normal. Have you done a full pull and looked at your AFR's? Also the purple injectors are 550cc injectors.

ive read the info and when the gauge goes green (to the left) thats lean or an i wrong ?

 

[10secdream]

Green is good my friend. The left is rich and the right is lean.

OBD1 lean spot. Over 4000 or so itll go rich, below that itll be in closed loop (14 a/f)

aem uego gauge, i was under the imprestion that keeping it in the middle (yellow) was the target and away from the left (green) was lean and risky

 

[10secdream]

You have been misinformed as lean is to the right. BTW you should go by the actual AFR and not by which direction the gauge goes. Either way most gauges start from the the lowest value and then go up. So it would start rich and then go lean.

Also why would they make "green" the danger zone... If that was the case I should stop at a green light and proceed on reds from now on.

thanks pips for all your help with this, so when monitoring the gauge(wideband) and setting the boost controller ive just got to keep it central and no problem with it going green ,just when it goes red too the right of the dial.

thanks again i can sleep tonight now.

i can up me psi then now i know theres plenty of fuel, ye ye ye ?

 

[tbcmorris]

what are you useing to tune with.

 

[pete.w]

this was part of the confusion ,i know its not the gauge im useing but its lean on the left

 

[pete.w]

this is the actual gauge im useing

 

[10secdream]

There different gauges completely. You can see on the AEM gauge that the left side reads 11 then goes up to 16. So It goes from rich to lean in the clockwise direction.
