Anybody know what "Buffer Overload" is??

[streetknight]

I'd be glad to send someone some DS files. What I'm experiencing is at NO certain RPM or gear on a WOT pass, the car noses over and all the sensors go to zero value for a second. Kinda like the ECM loses power. But I don't think it is losing power because the values on the BLM tables stay in place.

Anybody got any insight on this problem or what might could cause and fix it?

It's driving me nuts.

Do you have the ribbon cable shielded? The BLM's stay in place because thats the only nonvolatile memory in the ecm.

Yep it's shielded.

Have you tried running the car with DS cable disconnected ?? I ran into the same thing, turned out the cable was pushed too tight on the ECM connector.. I leave it backed off about 1/8" or so and all is well again..

Thanks for the reply, but yeah, I've tried it backed of a little. I've got a shorter cable coming, we'll see if that helps.

Send me the files. But from the what you are describing, I am not sure it is a buffer overload. From what Red told me, the Buffer overload only happens at high boost. When it was happening to me, it didn't really affect how the car was running. Just showed up on DS. Sounds like you need to look closely at your postive battery lead going to the starter and make sure it hasn't worn thru a spot and grounding out. When that happens the car behaves as you described.

I'll send you a file or two Sully. I guess it may be time to go on a wiring expedition. :frown:
