MGF EPAS and Ardunio
Good day all
yesterday I for some reason bought a MGF EPAS system ( ECU et all)...now i have seen speed controllers advertised for the speed and RPM? inputs- and wondered if an Ardunio could be used to supply suitable frequencies ??
And if so ..it would be possible to base the frequency out on GPS speed?
How are folks controlling the assistance maps in current installations - or is if just on\off ?

why not on for first and reverse? off for the rest.

Re: MGF EPAS and Ardunio
I do it on a pot - which controls a 555 timer. One owner I have fitted the EPAS for uses it only for very slow speeds then he turns it off for normal running - the other three use about 2/3 of the control all the time. No good limiting it for 1st in my case as I don't use 1st gear. Our EPAS drawing here http://www.scimitarweb.co.uk/~nenoggins/Wiring.htm

Re: MGF EPAS and Ardunio
Not sure what the EPAS requires, but yes, the Arduino would make life easier for you and be infinitely adjustable to get it the way you want it.

Re: MGF EPAS and Ardunio
The MGF EPAS needs two square wave signals, 1000 to 3000 Hz for the RPM and 100 to 250Hz for the roadspeed.

Re: MGF EPAS and Ardunio
Easy way of getting a speed output is to use an ABS sensor (anything - whatever's cheapest on eBay; I used one from a Corsa I think), get it to pick up on a propshaft bolt or even the yoke, and feed it into an Orange relay used on non-ABS Corsas and Zafiras (part number 09185826) which will give you a decent signal to take into the Ardunio. You can then take that signal, scale is as required and send it back to the EPAS.

Never try and argue with an idiot. They drag you down to their level, then beat you based on experience.

Re: MGF EPAS and Ardunio
well the Ardunio has a built in Tone generator - could it be that simple!!

That sounds promising, have just got an MG unit, but still need to find connectors and UJ.manny wrote:well the Ardunio has a built in Tone generator - could it be that simple!!

Couldn't find the manual controller unit on ebay referred to by Peter... So a substitute solution would be nice.

Here it is - does may makes of cars as they all have the same sort of speed input.

Re: MGF EPAS and Ardunio
looks like the Ardunio will only allow one pin to generate a tone- so i would need to generate the different frequencies between two pins - with minimal oscillation between the two to avoid the EPAS turning off
Or a simple 1500Hz isolated circuit to feed the engine 'on' and Ardunio feeding the speed sensor ( better option?)

Re: MGF EPAS and Ardunio
yes I saw that and that's precisely what I searched for too!!!peter freeman wrote:I put his name on the EPAS drawing I did - it is Monday though/
Maybe because I logged in via Ebay Ireland (gives me English and Euros)
