Just want to make sure i can do this

[vbryanv]

i was just confused, wondering with this set up and how it works. what i mean if i hook this up, i will get the reading my AFR, but how will the stock ecu now gets its signal and i,ve got no way to adjust reading
i did not buy it yet its a toss up between afpr and this gauge. i cant afford to buy too much right now...but gonna to squeeze some money to get something else.

any feedback will be appreciated.

i'll try to explain a little better.

right now i dont have a AEM UEGO Gauge-Type Wideband.

lexus maf *not install yet
I just recieved the christmas gifts i bought myself.
1. walbo 255 fuel pump
2. rc 550 injectors
3. greddy boost controler

Basically from your list you can install the greddy boost controler. You would be alright installing the fuel pump as well but no real point untill you are able to get a few more items.

A wide band like the AEM UEGO is not necessary but you do need:

Walbro pump
550cc injectors
lexus maf or the LIPP maf
FPR

Basically by installing the lexus MAF with your 550cc injectors it helps to balance the extra fuel with extra air.

You can leave out the MAF but then you would need a way to tune and the ability to see the air/fuel ratio.

You can install the wideband without having anything to adjust the ratio
It is only a sensor so does not effect anything only gives you more information.

thank for the help

[Green7mgte]

installing your mods that have to do with air to fuel ratio you have two options.. one standalone like Maft or tuning with an air flow controller and a afr guage.

installing the lex kvam with the 550cc injectors would be considered standalone.
