Thread: Take a peak at AFRs on this 3rd gear pull and comment if knowledgeable!

Looks good to me

Oil pressure shouldn't be bouncing around like that.

Once you get into boost and run the RPM's up it is locked around 11.8 and that is fine.

Your absolutely right Vadim, started bouncing like that when I added my AFR gauge to the mix...re-grounded, tried a different power source, still doing it. Bumped fuel at 2200rpm to keep in under 13 in that little patch...I want this to be my "safe" file, then build a second file at 13psi for cold/night conditions with AFR around 13.5 to 3000rpm for faster spool up, then 12-12.5 range to redline. Sound idea, or too aggressive?

agree

i hope its the wiring/otherwise... else ur bearings wont last long

I think I found the reason...I have a single 16" slim fan for my radiator thats wired always-on running to the same fuse as the gauge. Might be voltage fluctuation from that...time to pick up a radioshack volt meter, I always lose those damn things!

Radiator fans should always be separate from everything else really, they suck way too much power. I'm used to mech gauges, no electrical interference FTW!

I wasn't even paying attention to the oil pressure..........Just focusing on A/F ratio :o

I am an oil pressure freak haha, I am always looking at it.
It does look like a boost gauge issue, more than an oil pump issue...

Your AFRs look good to me, personally, I prefer to be a little bit richer on the AFRs, than risk for a lean condition
