msq v1 piggyback
 

I have a guy local to me trying to sale a piggyback v1 i didn't know that megasquirt made a piggyback i thought it was only standalone setups so if anyone has messed with it please lmk thanks

Walk away, you don't know enough to buy it and use it.

Way, way, way back in 2006/2007/2008 when we first started working with megasquirts in the miata lots of us would with them in parallel with the stock ecu. We were running the Kingofl337 mods and using switches to switch fuel/spark back and forth between the MS1 and stock ecu.

that's why I was asking for info i have never heard of a piggy back only stand alone systems plus he is asking 100bucks so its not a big risk

I mean unless you are trying to run it in Lemons or something I would still say it is a waste of money and time. The MS1 is way old and not really worth it.

thats what I was looking for thanks for the info
