Hi Guy's,

does anyone have a suggestion for sourcing a Frankenso in the UK. We are wanting to fit rusEFI to a 91 MX5 (Miata) manual. I have sources and flashed a brain board, but I dont fancy building all the IO from scratch on vero board.

Plan B may be to get an old ECU and remove the CPU and wire in a brain board, but I suspect the logic levels will be 5V rather that 3v3 on the ARM processor.

Thanks,

Ian.

You are right, the 3v<>5v issue would make chipping old ECU unpractical - you would need an adaptor board to shift output levels and divide analog inputs.

I ship Frankenso boards worldwide from https://www.tindie.com/stores/russian/

Hi yes I found the online store, but the shipping is very expensive and then I believe it will need tax and duty paying for imports.
Im wondering if I can get 10 made up by a UK based PCB firm and supply them via this website. I will looking it.

You'd need to pay VAT at 20% plus a handling charge which is typically £15.

Rhinoman,

Thanks for the info. Which version of the board is most compatible with a Mk1 1.6 NA Miata/MX5. V0.4 or V.011?
Im hoping to make this plug compatible while we are experimenting as the car is used daily.


Thanks,

Ian.

0.4 and 0.11 is referring to different boards altogether - see http://rusefi.com/wiki/index.php?title=Hardware:For_Sale

0.4 was designed to be a PnP in a 91 Miata.

I strongly suggest buying at least one kit before trying to source all the necessary components. Manufacturing the PCB is only the first step - the second step is sourcing all the right components, a couple of them like SD card socket are eBay specials.

Which ECU do you have? the early JDM models were different to the UK models though I believe that the connector pin-out is very similar.
