Default Afr on wideband

well, the honda is out till i get some more fuel and a tune. Got the header on, 3in exhaust and the aem wideband..

idle afr: 12.5
wot afr below 6200: --
wot afr after 6200: 16.8

So it's getting no bottle for now.

Think the injectors or pump is going out? Bad o2( even though cel isn't on for it) or just need a tune with just i/h/e?

You need a tune!

AFR for idle should be around 14.7
WOT should be no higher then 14

You probably just need a tune. It wouldn't be a bad idea to check your fuel filter though and send out to have your fuel injectors cleaned.

going to replace the filter, fp and put on a afpr.

Thinking the person who did the swap may have left the cx fuel pump in the car also.

Well, for night i a friend had a v-afc for cheap( i mean really cheap) to use to get the afr straightened out till i can get the money for the neptune rtr.

On a side note the afr is now 13.1 in 3rd from 4k to 7800 at wot. Car runs 10 times better than what it did before.

The vafc hack is only temp, i know it's just a bandaid fix.
