Over run / crackle option

Post by WRS4 » Sat Jan 12, 2019 1:32 am

When i had my car stage 2'ed at MRC, they added the overrun/crackle to the map. To be honest I did like this BUT not all the time as it would have annoyed the neighbours but also im no spring chicken. I went back the following day and they kindly removed this form the map but did say they were looking into trying to find a way of adding the overrun / crackle to a button inside the car so that it was optional and I would actually go for this as it does make sense to be able to turn it off as and when you want.

Anyway a year on MRC have either decided to not go for this or they cant solve how to do it, I did ask them a few months ago but they still didn't manage to come up with this system as of yet. SO MY QUESTION, has anyone found another company that can do this ? as I say I do like the sound but not all the time and as with most of us its a case of have it or don't have it but there is always a time and a place so it would be cool to have it at the push of a button.

I also have mrc stage 2 with crackle and love it but occasionally it does draw attention when perhaps not appropriate lol
You'd like to think that the crackle map could be linked to the sport button. I'm no expert on this but my S button changes throttle response which I'd have thought is part of the map

You would think the ecu could take two maps if the throttle response changes, i had an astra that was the same and had the sport button map changed only
