I looked back at all the emails and I got an update every day until they showed up. I can't pull up the initial order to show what city it came from now.
Like Sean said, for CHEAP, what is there to loose but a little chump change and a week of...
I think if you don't already have an account at AliExpress and you go to the web page for the Chenho sensor in the next ~8 hours they will give you a price of $1.32 and free shipping 🤣 🤣
That's what I just did. They showed it as a new customer...
I had confirmation of the order and updates on shipping and even when it had cleared customs. No issues. I was as surprised as you. Now if they work the same. I should have ordered 3 and melted the goo out of one for the price that they were...
This one, the Chenho, was $10 yesterday when I looked at it. Now it's $1.32 🤣This one I didn't see yesterday, but I see it is $17.77 today.But it sounds like you are saying that neither one of these is the one you bought?
On your...
That's pretty interesting. Did you have tracking on the shipping? Wondering where the shipping to you started from.
Is it a Chenho brand?
I'll keep my eyes open for any updates you might have on these.Man, when I google "Ruian Chenho Auto...
I ordered 2 6 bolt knock sensors from a vendor I found while on Amayama. It was AliExpress and the sensors were listed as MD141510's. They were very easy on the wallet. I ordered them the 17th and they came in today. A few pictures for the...
I think the knock sensor is akin to an audio microphone. The signal is very weak in terms of voltage modulation. Not something you can measure with a multi-meter - maybe an o-scope. Honestly I've never spent time trying to intercept or put a...
Yes, it is a piezoelectric microphone.Yeah I think that's how it's going to turn out.
I think an expensive meter like a Fluke 87 would do pretty well for the normal running (no knock) parts of it. But a meter like that costs $450 these days...
I'm thinking the IAT input might not work at all for this, because maybe the knock sensor voltage is ac rather than dc. So then an ac voltmeter might be more like what you'd need (Vac on a multimeter). I can try to check this out sometime in...
If you end up trying one of the non-OEM knock sensors that came up in this thread, or even trying to verify your old one for good or bad, we might be able to evaluate how close it is to a known good OEM sensor by comparing its behavior to logs...
UPDATE:Recap: We had retarded the intake cam, from 6 degrees advance, closer toward "normal", and set it to 3 degrees advance.I had to increase VE several % to get airflow back to 0.25g/s. The vacuum at idle with this new cam timing was...
Well that part of the log, from 173 sec to the end, looks good to me. I can even see there that when rpm starts to drop a little, that is when timing jumps up to a high advance. Which would help pick up the rpm. So it's like it says in the...
Yeah if the valve guide IDs are just a little too big it lets the valve stems wiggle around sideways too much and your new stem seals can go downhill pretty fast, or something like that. That's what it was the only time I've ever had this. That...
I just noticed that the ? help on the RPM/TPS page says that timing at idle is varied to help control idle speed. Not just the ISC. So maybe this is where the unexpected timing numbers are coming from, and why they don't match the chart we can...
The 17-02 log looks pretty decent.
I've been looking at the part after the throttle blip where the rpm gets down into the 700's at 8.4 seconds.
At the same place the wideband gets maxed out full lean (even more than maxed out - it hits 4.14 raw...
This is a very useful explanation. I just changed mine to 470. It does seem to be helping. Log attached.Unfortunately, I didn't read your entire post before I started logging today, so I didn't capture the ISC position before startup. However...
