looking into a piggyback for a BOSCH motronics ECM V8.

MUST retain the ECM as it is tied to the security system AND outputs various other functions. As well as OBD2 emissions....

suggestions? (MS does not count)

 

Whats wrong with megasquirt?

 

its not a piggyback...

 

it can be.

 

No it can't.

It can run in parallel, but it can't intercept and modify signals like a piggyback does.

 

Why would you want this over complete control?

 

because why on earth would you want full control AND obdII compatibilty?

 

Who said I that did? OP wants a piggyback for the reasons he states, seems reasonable enough to me.

OP wanted a piggyback, Brain said MS could, I countered that it couldn't but could be run in parallel to the stock ECU.

 

i counter that I like turtles.

what's left the xede or 15 powercards?
