I have a MK1 1.6 MX5 which was imported from Japan a couple of years ago with a turbo fitted.

It has an HKS fcon 'mini' piggyback unit which has failed. I have read online that the ROM chip in them can fail when jumpstarting which is what I was doing when it failed. Can it be repaired?

And now I don't know what to do. Any help or advice appreciated.

Have you tried posting on MX5nutz ? They seem to know a bit more about this stuff.

Last time I saw one of those mentioned the general advice was to dump it and replace with something better. Even an eManage Blue is a step up.

Jonny I may have a FCON mini spare which you can have for postage assumign I can find it. Its from a turbo'd NB 1.8 though so not sure it is of any use?

I replaced mine as its basically pants.

I replaced it with a piggyback ECU that was recommended by my trusted mapper. Theres no point in getting an all singing unit if your chosen mapper has no experience of it...

I thought they were supposed to be good, is that not the case?

Maybe. Problem is nobody over here knows a great deal about them. Do they control timing or only fuelling?

i could swear you started off with an EMB laz?
am pretty sure it does fuelling and spark timing, but you can only go so far on EMB.

your best options are e-manage ultimate, megasquirt, or adaptronic. the latter two appear to be more capable, at least they are a becoming a lot more popular - of those, MS is cheaper but has slightly less features built in (i think), but they'll both do absolutely what you need. EMU i don't know much about...

i went MSPnP on mine, for ease. the mazda ECU harness plugs straight in.

laugh yes, the EMB does, I was asking about the "HKS fcon 'mini' piggyback unit" laugh
EMB is fine for most setups, it's just when you start pushing for bigger power they are a bit lacking.
