I don't recall. I thought you yours we had an indicated error. Which mine does not have. It claims to be working correctly. But is not

Ah. Seems different but as usual I didn't really know what was going on with mine anyway.

At this point I still have hope. And everything has been fixable. If this next set of lifters also gets trashed then I'll be a lot more bummed.

Overall I've had a lot of fun with this project and learned a lot. Biggest let down was being screwed over by the machine shop, seeing all the signs of Det after initial tuning, and these trashed lifters. Everything else had been a good learning experience.

Getting fucked by the machine shop was the biggest let down. 4 months late. $500 over quoted price was really hard to swallow. But life goes on.

If I remember right you are running some beta test code for the MS. I bet that is your VVT problem, some bug in the software. I have never seen anyone have that VVT problem before on a miata. The way it just stops working sure looks ECU related.

I agree. I was going to revert to the stable release 1.5. but that has a bug in the communications. And the fix is to upgrade to 1.5.1 beta....

I'll revert to 1.4.1 when the car is running again. But that is a different way of tuning idle and the like so it takes more time.

I had somewhat of a similar vvt issue: it would start spiking/dipping like crazy, intermittently. It was a wiring issue

Mine literally locks up. No spikes or weird behavior. Just frozen. Target angle is stuck, measured angle is stuck.

​​​​​​​That is normal for all machine shops.

No it's not. Sounds like y'all have some crappy places and think that's the standard.

There's 2 within 5 miles of my house, they've never had a single one of my parts, and that includes blocks/heads/etc. for over a week. For any sort of work.

I have yet to find a machine shop on the east coast that is on time, price quoted, and does good work. I have used probably a dozen now and all are like that. It is even worse if you give them something around the end of winter or start of spring.

In my experience the best way to find a good machine shop is by talking to people at the track until you find someone who is happy with their machinist.

I know of one machine shop here that's doing great work and is reasonably priced. The other side of the coin is that if you don't push him A LOT, he will never start your project. If you stop by every few days, he'll eventually get around to it. He usually claims it'll take two weeks, which then turns into two months.

Megasquirt Support Forum (MSEXTRA) ? VVT Issues (View topic)
If memory serves right there was somebody else in the MS subforum who had a similar issue with some value not updating. He was using one of Reverants CAN boards. Not sure what it was, but I Believe the interim solution was not using the CAN board.

Fwiw this machine shop came highly regarded and people have had good experiences with them. They do machine work for English racing. They just fucked me. Also I was told to order the wrong bearings. Anyone want a set of ACL STDX bearings?

If you could find that link Stefan that would be awesome. I'd be interested in that.

Anyone know if there is a break in procedure for new lifters?

In the V8 world, it's a 20 minute run in on startup, at 2K RPMs, covered in assembly lube with a really high zinc oil. Then change the oil. I've only used OEM lifters, but I've never done anything special on a BP, just fire it up and go and my valve clearances/lifters have been fine, so I kind of doubt your problems are from an improper run in.

I'm afraid I conflated DNMakinson's Synch Error issue (see below) that was fixed by cutting CAN wires with my own VVT issues I've experienced with rusefi. So it seems unlikely that CAN is your problem.

Ugh. Did not want to downgrade to 1.4.1. But the msextra guys have been silent for over a week now. So I'm out of luck.
