has anyone supercharged a 1.6 Mazda MX5?

my mate has asked me to help him supercharge it as it he isnt confident to supercharge it himself, ive suggested getting a megasquirt ECU to run it however, hes also asked me about ECU PIGGY BACK devices, has anyone ever used one when supercharging or turboing an engine, i have seen people use them to do just this but know one says what device they used.

im confident with using a megasquirt but would really like some info on piggy back ECUs as really im just interested i know some alter just the timing some can alter fuel delivery aswell.

any help is much appreciated

Thanks

Megasquirt is used on most boosted mx5 engines. I cant see a piggy back ecu being able to do a proper job tbh and a "proper" one would cost as much as a megasquirt anyway.

The most popular piggy backs for a boosted 5 would be a GReddy E-Manage or a Jackson Racing Powercard. The majority do use a Megasquirt nowadays though.

You can boost a MX5 with the stock ECU but not by much. Goggle is your friend.

I have turbo-ed my 1.6. based kit using a Microsquirt V3. Basically a SMD sealed Megasquirt V2 with limited in/outputs aimed at bike market but plenty to run an MX5 well.

One went on Ebay this week for just £140. New ones are going for ~£280. Way better than a piggy back or band aids but you will need to wire it in yourself.

I have supercharged mine and built a megasquirt up from a kit tof parts, i enjoyed building the ms and it ran well on it, but i am now running it on a ms built by a guy called reverand, hes on turbo miata, mx5nutz etc. I would recommend buying a ms built by him, it will come plug and play (plugs into the existing ecu socket) with an excellent map and second to none aftersales. He offers various options from basic to more specced, I have switchable maps, launch control etc. And honestly unless you fancy the challenge, just speak to him. Financially I wouldn't bother building my own again, and if you want to sell it on they are always in demand.
