aem uego

[ooraceredgt]

i have a aem uego with a a/f guage and was wondering if anyone elses guage fluctuates when just regular driving. also i placed the O2 sensor on the last bung toward where the rear cats used to be. i have a pro-chamber without cats and wondering if this affects anything.

The air fuel ratio is always fluctuating, so it's normal. Normally the bungs need to be closer to the headers to be accurate. However, the place you have it should be fine. It'll just be slightly off.

yep, ive got one and it swings from 14-15 or so usually during cruise... i hav noticed that at times it will be WAY off... like it will say 12:1 during cruise with no change in tone or performance, all i have to do is rev it up once real quick and it fixes it... but id say that 99% of the time its fairly well dead on but that last 1% is WAY off lol

but to let you know, the tune i set up with my predator would run abotu 13.8:1 at 5k rpm with stock manifolds and a prochamber, and since putting longtubes and h-pipe in. its at 14.2:1 at 5krpm
