Ping problem

[akwilks]

I have mentioned pinging in recent posts and come to realize this could be a serious problem....I have lost faith in shops around and could really use some help...dont want to go through another motor..ever, so is there anyone who can help me diagnose and fix this problem in my area? I live SD near the Elisworth AFB.

Re: Ping problem

First - Get a scantool (Datamaster, etc....) so that you have some accurate representation of exactly how much retard you're seeing.

Second - Do a full tune up....fuel filter, cap, rotor, plugs, wires, 0 deg BTDC timing check, exhaust restriction check, see what chip you have in there, etc....

Third - Try better gas to see if retard is real or not.

Once you've done all that let us know what going on with it. You might want to find some local SyTyers to assist you as well (check the regional forums).

When my ping is high, I usually get pwned by a headshot!

Re: Ping problem

More information needed to help you. What octane fuel are you running and how much boost? Have you logged with Datamaster or another scan tool? What mods do you have, if any?

Re: Ping problem

My Ty has 50# inj(I was told) custom chip from Dynotech in which they have revealed nothing to me, cold air intake, IC pump upgrade, MSD ign, 2500 stall convertor, GN turbo w/ext wg and boost controller, custom exhaust w/o cat...the engine was just replaced with 8:1 TRW pistons otherwise, everything else is stock...I'm running no more than 14psi of boost...The gas here is 91 octane...I'm new to these trucks and the one I have is a gem(68k mi).....dont want to destroy it by my own hands...I feel I'm taking better care of the truck than its previous owner who was destroying engines left and right....I had to replace the engine because of the previous owner's need for speed...and blind faith in engine shops...I love this truck, the throttle response is amazing..just checked for ecm codes and there were none....I dont want to start tweeking things without having a fair understanding of how the truck operates....thats too expensive

Re: Ping problem

I would get Datamaster and do some datalogging to see if and how much detonation you're actually seeing. I also run 91 pump gas and have my EBC set to 17psi with very little knock retard. Need to find out what that chip is you have. I would ditch it and get a Phil Long chip if you have 50# injectors. Also, an alky injection system would be a good investment if you plan on running high boost with 91 octane. 14psi is pretty low, so you shouldn't be seeing much knock at that level. Check it out with a scan tool and let us know what you find.
