In replying to this dead thread I realized the forum was screwed up in my display. Was showing really old posts as the newest. Sorry for the resurrection.

My forum browser was not showing pinned/sticky topics until I searched and looked at one. Weird. Here is the link, you should be seeing about 20 pinned topics in the megasquirt forum, if not then you are having the same issue I am seeing. Not sure how to fix it.

Cool, good troubleshooting. Sorry we couldn't help out.

Replaced the Odyssey PC680 battery. Putting together a plan for the 8.8 rear to upgrade. Torsen t2, new axles, 9 inch outers instead of c-clip elimniators??

Pics are back online through photobucket for a while, but may not be permanent so I am working to upload them here on the server and relink. Check out the article https://www.denverpost.com/2018/05/17/photobucket-image-hosting-plans/

Just make sure you charge the battery completely once alternator is fixed and make sure the battery is good. We had one vehicle run terrible and tried everything for weeks on and off only to end up being a bad battery that supplied low volts to the entire system.

It has been a couple years, the car is still in the same state as mentioned in this thread. It runs good, I take it for a fun ride once a month on average. I have all the parts together to take it to the next stage of the build but I had lost my interest in it when my son passed away on Oct 1st of 2015. Over the last couple years I have been working on cars with one of my sons high school friend. I helped this young man install megasquirt on his miata and then rebuild his miata. I gave him my sons car (90 eagle talon turbo) and I am helping him right now on upgrading it to megasuirt, FMIC, 22psi. I have slowly got back my interest in revisiting my rx7 and taking it on to the next phase. Maybe you will start to see some updates in this thread. I have been out of the community for a couple years so I have lost track of everyone and what has been going on.

Been helping one of my son's friends install MS2 on his 94 Miata. He has been doing all the work and I'm just filling in to help him learn. Got it running on Saturday. I've been out of the game for a while so it was a fun victory. Should be tuning next weekend. I am still around and working on megasquirt, who would have guessed, haha

Took the car to Pueblo Motorsports park to get 1/4 mile times. Tech'd in and lined up, but never got to race. They had problems with the staging lights and timing system. They don't expect to have the track working until September. ughhhhhh

Mazda never released the specs so I'm not sure, haha

Went out to the race event, but rain delays pushed back the 1/8 mile drags. They never did start before I had to leave. Still had a lot of fun. I must have been asked 50 times how big of turbo it has. lol

The car is back up and running. I took it on a 100 mile round trip in the heat and everything seems good. Might take it to a street racing event this weekend and try it in 1/8 mile drags.

You do not need the air flow meter or mass air flow. Megasquirt normally runs as speed density and only requires a manifold air pressure sensor (MAP) which is part of the megasquirt box. I use one of these air valves from an Rx7 for fast idle on my simple setups. http://atkinsrotary.com/store/images/D/N332-13-720Detail.jpg

If your cross country trip brings you through Colorado and you have some spare time I would love to talk over the Megasquirt setup with you. I would ditch the AFM, oem cold start valve and idle control valve. Start simple in that area and use a newer on/off air valve until you start to get more understanding of the EFI system. Then start playing around with nice to have features.
