Re: Hellen 72 - Miata NB2 up to 8 cylinders

Hellen72c will have a WBO module. In order to simplify the LSU sensor wiring, we used a board-to-wire connector on the board: image.png This is a XH series connector (XH-8A) with 2.50mm pitch and 3A current rated pins. We use double pins for the heater output and ground. The best part is that JLCPCB...

Hellen81 PnP for 81-pin M7.9.7/ME7.9.7/ME7.8.8/Yanvar7.2/Micas10.3

Hellen81 is an ultracompact and cheap yet full-functional 8-Cylinder ECU board. The board is compatible with some 81-pin ECUs: Bosch M7.9.7; Bosch ME7.9.7; Bosch ME7.8.8; Yanvar7.2 (Январь 7.2) Micas10.3 (Микас 10.3). The board is NOT compatible with 121-pin VAG ME7.x vehicles!

Re: Hellen 121 ME7 for VAG PnP ECU

As an Audi guy, this makes me very happy!!! As far is I understand, you have a ME7.5/ME7.1/ME7.1.1-compatible ECU which uses a 121-pin connector (81pin+40pin). Currently we developed a Hellen81 board design, which is a 81-pin only version for ME7.8.8/ME7.9.7/M7.9.7/Yanvar7.2/Micas10.3, and which is...

Re: Hello there!

Most of the MS2 derivatives use just the same BIPs as the Prometheus does and you can just solder B to C and use the signal, but a buffer of driver IC would be the most elegant method I think. Yes, you can solder jumper wires instead of BIPs. I've used Prometheus with logic-level COPs just fine: !l...

Yes, that's true. If you enable this option, it will use batch fuel/wasted spark right after the first sync (until fully synced):
