Sorry, I thought you were referring to the AFR Corrections table, not the Feedback table. The trick Emerald showed me for turning on/off closed loop or adaptive at a global level was to set the coolant trigger to a very high value that the engine won't reach in normal operating conditions. In the screenshot above, that's why it reads 120C. When using Closed/Adaptive, it is changed to 70C.

Correct. No, you are changing the values in those cells. In the Emerald, + adds fuel or timing, and - removes fuel or timing. To enable adaptive, you need to have values in the lower right section of the tab shown below under "Conditions that enable update of the corrections table".

I don't recall how to turn on adaptive. I'd need to look at the manual or the software to jog my memory. The difference between closed loop and adaptive is simply that closed loop makes the changes live and does not store the values. Adaptive, identifies those live changes and stores them in an AFR corrections table. At some point you can accept all or some of those changes which in turn updates the map with the revised values. When you do this, it's a good idea to save the map with a new name so you can always revert to the original if needed. Another advantage of adaptive mapping is that it gives you a way to safely walk up on a big change when doing initial tuning. Closed loop and adaptive both have user settable values that limit the amount of allowable change. This is to prevent a massive erroneous reading that could create an overly rich or lean condition. As I recall, Emerald sets the default at a pretty conservative value. Maybe 5%? Now imagine the cell actually needs a 9% change. Closed loop won't get you there and will continually limit the change to just 5%. With adaptive mapping, you can update the base map with that 5% change, then the next time you run the engine, it will identify that additional 4% change needed and enable you to create an updated, accurate map.

Based on your questions, it sounds like you have not read the instruction manuals available at Emerald's site here: EmeraldM3D.com - Software / Manuals The Emerald K3/K6 Manual v 057 is a good primer and will help you understand the various terms and what the Emerald can do. It's not written for the expert. It's written for the average hobbyist. The Adaptive mapping aspect is covered in the section beginning on page 31. You want to use the Emerald to log data, not the Innovate. That simply feeds the AFR to the Emerald and won't tie that into other key parameters available to the ECU. The Emerald allows you to map multiple channels and its use is covered in the Data Logger Guide on the page linked above. Load site is a key item to log and is how the software identifies throttle input. Coupled to RPM, it equates to how much air is being ingested by the engine. The mapping tables generally have Load Site on left (the rows) and rpm on the top (the columns). The cells then contain the elements that table maps. e.g. timing, fueling, AFR.

Was there something amiss that caused you to make those changes? If you have the WBO2 working correctly, you can log the AFR, load site, and rpm to identify if anything is off and then address it. You can also turn on the adaptive mapping, plug in target AFR at each load site and rpm and just drive it. This should all be covered in the documentation available at Emerald's website. I can try to answer specific questions if you have them, but I may not know the answer off the top of my head as I haven't had the need to mess with mine for a few years.

There is a lot of info here and I'm not 100% certain I follow the issue you're chasing given the talk of tuners and midrange lean misfires. Is the following correct or did I miss something from a post above? You car worked fine with the loaded map for years. Let's call this your baseline map You had an issue with the WBO2 so replaced it and some wiring, after which the map switched to another map loaded into the ECU (we'll call it the starter map) and your problems began. Is the above correct? If so, is the goal to simply get the baseline map to operate as the default and have the working WBO2 for either closed loop mode or data logging? Did you make changes to that map while troubleshooting or is it unchanged from the past? Based on the answers to the above, I may have some suggestions based on my experience with the Emerald.

Honestly? It's not overwhelmingly promising. Given the sensitivity of the information, I'm not a big fan of sharing it with someone who joined the forum expressly to access it. Particularly when their IP points to the UK where the likelihood of misuse is much higher given the far larger number of Caterhams on the road. Ultimately, it's up to the person who owns the IP. If you PM me a username on Blatchat or pistonheads that I can verify by PMs there, and you have a positive reputation, I can share those results with him.

See this post:

To manage storage and page load times, all images are automatically resized to no more than 1000px x 750px. This is optimal for a forum and results in a much, much smaller image. Looking at your specific data, you have uploaded 340 images, with an average storage size after compression of under 300kb. Your largest is 770kb and you only have 20 that are larger than 500kb. Therefore, it's safe to say that uploading a resized image under 1.9mb won't impact quality. That said, you are about to reach the 100mb storage limit for an unpaid user, at which point you will no longer be able to upload images (Paid Members can store 500mb). I'm comfortable lifting both limits by 20% for now and will investigate a higher limit when I have time.

Posting in the General forum to maximize visibility. The outage over the past 24 hours was due to a failed autorenewal on the domain. Mazda had this set up to an active payment method, but not only did it fail, the registrar never contacted him to highlight an expiration issue, therefore no one knew about it until the site stopped responding. He worked with registrar to correct the payment issue about 6:15am PT yesterday but it took a full 24 hours for the change to propagate. To avoid this happening again, we will be changing the registrar to our forum ISP who is responsive and has proven error free over the past few years. -John

@Bob.Dobos, Fejer category is added. Please send files to @Croc. Thanks, John

Scheduled to arrive at its new home on Tuesday

I broke this off into a new topic since it was appended to the thread about looking for Jake LaMont's book on building an engine. One of these things is not like the other -John

Found the problem and the fix has been made. It now works correctly for my test account but might take up to 24 hours to fully propagate. @TEM when you get a chance, will you please change your email address back to gmail, then send me a PM so we can test it? Thanks, John

Those are not the issue here based on my limited testing last night with a newly created gmail account. I also confirmed the new account can receive an email directly from the gmail account used as the send-from address for notifications, so that address is not being blocked. I suspect this might be related to the extra routing from mails that go through our hoster's UK servers, but the lack of consistency is odd. Having more data points of people who are seeing this will help me do further digging on commonalities that will in turn help with any support tickets I need to open.

Thanks @panamericano and @thewebgal. Now we know it works in some cases, and I suspect most, which is why this hasn't arisen before, but we still don't know the frequency of the problem. Are there any others for whom it is not working?

You're the first to report this. I just created a gmail account and confirmed I am seeing the same behavior. Is anyone else seeing the same thing or are notifications to your gmail address arriving correctly? Thanks, John

Interesting. The only photo I received was taken in a dimly lit portion of the factory by my dealer when he was there. Other requests were ignored. They must have known I was a Westfield owner I had wondered about a Rich Kamp connection but didn't find anything on his website. It's a nice spec and the asking price is just about what it costs at current currency conversion rates less the international shipping.

Good catch. Not only not CA plates, but not US plates. This one shows a building with Caterham signage and RHD cars in the parking lot. Given it's a '21 model year and not yet completed, I'm curious to hear the back story. I suppose it could be a scam, but they would certainly be chasing a very limited market.

That's a nice spec. Provided someone likes the color, it's an interesting option for someone considering ordering a kit. Given it's in Sonoma, I wonder if Kampena Motorsports is involved in some way?

Last night I finally got around to updating my website with the Caterham story. While uploading photos to the modifications page, I realized I didn't have one that showed the 3D printed battery hold down, fuse box lid, and coolant junction cover together. Given they share the same ribbed design with the hope of making them look more cohesive and intentional rather than haphazard choices, that was a miss and was addressed this morning. Adding that photo here as well to show the end result. -John

I drilled out a lowered floor rivet, then riveted one of the spare cable tie wrap mounts in its place. Lousy photo, but it should give you an idea. -John
