ms

[I am not very bright]

what is a ms is it better then a piggy back unit

[Turbo-Brown]

MS or MegaSquirt is a full engine management system which replaces the original ECU and assumes control over engine functions like idle control, fueling and ignition.

A piggyback modifies the behavior of the standard ECU.

so it would be better to go for the ms if im right

[Turbo-Brown]

I would say so

[I am not very bright]

how much does it cost

[mattG]

MS will allow you to run bigger injectors and has programable outputs to control lots of other things, electric fan, nos, boost control etc.

[I am not very bright]

thanks for that but does it control rpm

It will run every aspect of your engine replacing your existing ecu, rev limits, timming every thing

[I am not very bright]

so do you now how much it costs

[mattG]

so do you now how much it costs

The price varies alot depending on what you want ie options fuel & spark only or full monty with lots of outputs, diy or fully installed.
Mine was done a couple of years ago so not sure on the price at a guess £300-£700 depending on diy, fully installed & mapped.
