Pinging when accelerating, help please!

Have to go to the dealer and have them upload it. The ping reflash. There is an actual name for it. I just don't feel good enough to search for it. Plenty of other posts have been made about it.

A few people have even done fuel pump ramp tests and found the factory unit to be inadequate/failing. So they upgraded theirs and it solved their issue.

 

I had that same problem. I took it to the dealership and they performed An Ecm reprogram. It got better. But still hear it sometimes. Hear it more with the 87 octane. Not so much with the 91. So I just use 91 now.

 

I'd be curious what a ramp test, for your fuel pump, would show @hueman562 ?

 

Mine tings or pings under a load as well, mostly under 3000 RPMs. Can sound really bad sometimes.

 

I'm trying premium shell octane, and running cleaner through the fuel! See if that fixes it, if not checking into TSB 0014-44 for the 12-15 models reprogramming ecm

 

That upgrade/TSB is not available for my year tuck though :/

 

How many miles does your engine have @10trdtaco ?

 

77k

 

Depending on a list of variables, it could easily be that your fuel filter is just simply saturated with contaminants.

 

It's a 10:1 compression engine which is pretty high. Unless you're at elevation, 89 is too low regardless of what Toyota recommends IMHO.

 

How do I check that?

 

So use premium to be safe?

 

Drop the tank and pull the filter

 

Dang. Have you done this? Rough or pretty simple?

 

If going this far, just upgrade the fuel pump with a kit from URD. The OEM filter isn't exclusively replaceable. ~$450+ for the OEM replacement. The URD kit makes it a 5 minute replaceable filter, for the future PM. ~$160.

 

Not on this rig but on others.

 

Yeah, this is a good idea

 

Yes. High octane gases only exist to prevent high compression engines from pinging. That's the only reason high octane gas exists.

 

The IT geek in me first thinks that your truck is sending an electronic message (a ping). Perhaps another descriptive verb is necessary?

 

I thought this kit was for forced induction Tacomas?? Or for both?
