Finally got it to idle. Issue seemed to be the fuel map was incorrect as well as it will not run with a hall sensor as my CAM sensor. I have to use a VR sensor for it to fire the injectors and coils.

I'll have more tomorrow, the computer that's being used with the ecu is not connected to the internet.

Hey everyone, I've been working on my locost 7 project with very strict budgets of spending no more than the car weighs! Finally I've got the engine running but she isn't happy at all. Some errors keep popping up and I am not sure what they are trying to tell me. My current error is a skipped fuel i...

Hello! Sorry it's been so long had a busy race season and some other personal stuff go on. Tonight I got the engine all up and running! After a bit of head scratching why things weren't working right I changed a few ground points and changed pin outputs to get it firing on all 4. I think one of my i...

Here is a video of it with power to the board with the USB and 12v power supply turned on. It does the same thing at the sae time interval. Looking at the logs it doesn't show any sort of "oh crap, disconnect" it just resets as if it is losing the com port. But even with it not plugged in ...

Every time that it hits 300n it resets and while it is plugged into the computer on the tunerstudio it will kick the ecu offline.

Here is a short video of what it does.

I'm trying to figure out what the LCD display is showing and I'm not too sure where to go to manipulate it. Has someone posted how to do such? This counter counts up to 300n and then the board resets, not sure if it has something to do with when I put it together or if it's a software thing. https:/...

So when I clip the jp01 jumper that same test point goes to 12v instead of the 7.5v

http://rusefi.com/wiki/index.php?title=Hardware:stm32f4discovery_repair#Diagnostics_steps Looks like maybe dead d1. I may just buy a second board so I can test other projects as well. Here is my setup for testing the power. https://uploads.tapatalk-cdn.com/20170120/f427e07eb3ffd99bfcf5b0b4849d1cc8....

Please remove discovery from Frankenso red board, does it still power up? Does ST Link utility connect? Can you reprogram the firmware? Did you kill it with 7.5 volts or was it while not connected to Frankenso? Little details matter :) https://uploads.tapatalk-cdn.com/20170120/81b0a0e7fede21553153f...

Cannot find your user on wiki, not sure if you need to activate it somehow. I can try help with stm issues if you provide more details, for 7.5 volts on power supply we would need CEO help. https://uploads.tapatalk-cdn.com/20170120/6a936bdc04be7eb4a26567729f3503cf.jpg Sent from my Nexus 6P using Ta...

Cannot find your user on wiki, not sure if you need to activate it somehow. I can try help with stm issues if you provide more details, for 7.5 volts on power supply we would need CEO help. I just reupdated it on wiki. Double check now. I was getting connection yesterday with rustuner and tuner stu...

Also, I am having issues with the stm32 when it worked fine yesterday. Today must just be a bad electronic day haha.

There are some changes that are in the more recent versions that are different from the Wiki. I would not mind making a how-to-assemble guide at all once I am able to get this one working right and true. Can you please create a wiki account? wiki and forum are completely unrelated things at the mom...

Thank you so much for the input! I will check the components out closer on Monday afternoon when I have my soldering kit on me. I dont care about having blinking LEDs as long as I am able to verify that the right components are working otherwise. I am currently working on setting up the STM32 board ...

What's the current state of the harness? Do you have battery mounted? Do you have starter button wired up - can you crank the engine? I have no harness made yet. I have a location for the battery, just above the passenger footwell. I have a simple starter panel ready to be wired into everything. Th...

Hello and welcome! I'm in the Dallas area also. Nice to see another Miata engine coming up, and the Lotus 7 project sounds like lots of fun. It is a ton of fun by far. Here is a picture of it in its current state. Not super pretty right now but it is all just making sure it fits right before making...

In terms of needed I/O: Sensors: - Crank and Cam are the most important - Manifold air pressure (MAP) is the best way to calculate fuel requirement (I'm using an external Chevy-style 3bar sensor) - Using MAP means you can get rid of the MAF sensor - CLT is important for warmup - IAT (post intercool...

Other than the pulley is a tad different but that shouldn't be a problem. I only think it is a 95 alternator. Haven't checked the part number yet.

I think I shall do so then.

I am in the Dallas area. I have definitely seen a lot of focus on the miata front here on the forums as I read through. That is true it really is just a 99 block with a turbo haha. I currently don't have an alternator for the engine other than a 95 alternator. I am not sure on the EBCV. I only have ...

Hey everyone. I am working on a lotus 7 project and found out about the rusEFI. Sounds like a lot of fun to learn and help develop if possible. I was trying to figure out which would be a better board to get for my project 7. The frankenstein or the frankenso. The setup in the car is a 2005 mazdaspe...
