During a normal drive in an NB2 with H72d, the tach dropped out and engine stalled. Tuner Studio showed critical error below. TS was connected but only for monitoring of VVT position. This critical error would cycle between PD12, 13 and 14. Only one would show at a time. PD14 being the most common. ...

This is what i had on my old VVT car with MS.

Thanks for posting! share some pictures and videos!

NB2 Miata H72D. Customer reported that VVT response would drop out intermittently. It is captured in the log screenshot below. I am waiting on the tune so that i can upload the full log. Earlier in the log, VVT position seemed to be responding as it needed to. Do we have VVT target available or only...

Welcome! Please post pictures of your project too!!

Please use YOUR eyes and identify where it is. This seems like a lost cause at this point.

You still have soldering and misalignment issues. Plus +12 also.

Please post high quality pics of the board as it is currently

Im 100% not surprised it let smoke out. Did you fix any of the obvious shorts or misaligned components? These kits expect a certain level of assembly ability. Getting it Because you are broke is going to end up costing you more money. For $480, the hellen would have been a smart investment.

Hi. Im seriously concerned with the quality of the soldering. I can see many solder bridges and misaligned chips. You really need to take your time and do it right. I dont mean this to be insulting and i hope it isnt taken this way. Is there a reason you went with this kit rather than getting the pr...

@mikey how are things going?

Quick update. She is up and running!

Added an upgrade today. MPXH6400 map sensor for all the boosts. With the built motor and bug turbo, i knew id be running out of map sensor soon.

I would like to test the m3 please.

Mikey, pm me your phone number. Id like to call and discuss.

We will make obd2 proteus adapter first for direct testing with available car. Then we can make the obd1 and test it on obd2 with double adapter.

Hey mikey. Only use firmware from the link. As of now, firmware through TS isn’t supported. If you can at some point, id love to see the popup you saw.

Please us firmware from https://github.com/rusefi/rusefi/wiki/Hellen72

Remove board from case. Press and hold the PROG button then power the board. This will put it in manual DFU mode. All lights next to the chip should be off. Then perform the manual firmware update through the console.

What firmware did you use?

Powdercoated M&M orange!

Thanks for getting back to me! Shipping out tomorrow now that its configured to your car.

Mikey, check your PMs.

@andrey mikey is a proud new owner of h72! Ships out tomorrow!

For wiring, the flex sensor is 12v, Gnd and signal. Does the signal circuit need anything external on the H64 that uses the digital input?
