Can the MS1 V3 run a knock sensor?

Is the ECU self learning at all? IE with a wideband will it set its own fuel and with the knocok sesnor will it learn its own advance?

Sorry, total noob when it comes to maps etc

Yes with the Ms'n's-extra addition. Afaik it's not tested with the pug knock sensor but with some calibration it should work.

I don't think it has self learning but I might be wrong..

As niklas says the v3 msns extra can be configured to receive input data from the knock sensor - but it is one of those optional extras if you buy it ready assembled. It is not self learning (spark timiing) and mearly retards the ignition by a set amount when receives a knock input. I believe the fuelling map can be adjusted faily simply with the aid of a wide band lamda and some test driving.

cool, thanks for the answers, Im gonna be using extra code anyway for the 60-2 pick up so will look into the msns extra as well . I'll be going self build route anyway.

There is a feature called autotune in that you can run in megatune but you will have to have a laptop plugged in while you drive. This, assuming you have a wide band O2 sendsor will allow the ECU to tune itself while you drive. you need to make sure you burn this information to the ecu before the end of each session though or all data will be lost.

 

The other way of tuning it is to take a data log and the run it through megalog viewer which will alter yoiu map for you. load this new map into the ecu, take another datalog and just keep doing it until your happy.

 

in order for the knock sensor to work you have to be running the ignition through you MS too.

I had auto tune running on my MS-II ecu.

It worked quite well until I realised the wideband lambda sensor was crap

mega tune wont do the volumetric efficiency tables though will it??

[Bono 0]

how do you mean?

It will alter the fuelling table which iirc is a percentage of VE
