possible cause of Pinging

[jliu]

I, and few others have had pinging issues with our cold sides. I have tried to check eveything that could cause pinging without success. Well, I decided to send the pro-pc back to Tom to see if the 5th injector is getting signals. In the mean time, I decided to check the continuity of the wires to the 5th injector. Well, one of the wires was open. At first, I thought I screwed up connecting the wires. But, my connections were solid. As it turned out, one of the wires going into the connector to the injector was broken. You would not know by looking at the connector to the injector.
For those who have pinging issue, I encourage you to do a simple continuity test to make sure your 5th injector is getting signal from the pro-pc.
I had spoken to Tom and he is looking into his supply of connectors.

I set this thread as a stick thread so it will always be on top.

Everybody please check your connector at the extra injector. Early on, we thought we had a couple bad PC-Pros. I swapped a couple out and posted a caution. We tested those PC-Pros thoroughly and found no problems. I sent replacements to a couple customers and they still had an issue. Then we found the suspect ACCEL injectors and thought the troubles were over. But a couple customers, like Jeff, still had an issue. Looks like he found his problem. Where there is one defective part, there may be a second or third. I urge all of you to check that connector if you are having any issues with lean or ping that you can't resolve. We have had two versions of that connector in stock. One with a red and brown (?) wire and one with two white wires. The one in question is the one with the red and brown wires. The one with two white wires is from a different batch and appears to be OK at the moment. If you are having any E-Cool issues, PLEASE check that connector. I will be happy to send you a replacement if you even suspect the connector.
