225/r26/Clio meg swap mapping issues

[Renny 5]

Since having my meglio, I’ve had this issue through out and chatted to others which ended up with a mix bag of answers, even spoke to afew of you about this and it’s still hit or miss so just want to try and finalise my thoughts about it before I sell mine next year.


Basically, had my meglio mapped several times by efi each time I changed something. Seems that each time I hit the limiter the ignition cuts for afew seconds, sometimes longer. Scoff seams to think that the ph1 225/Clio 200 ecu that I’ve got doesn’t handle +20psi well. Others say that their megane 225 (ph1/ph2) have had this same issue for ages and just live with it. Someone mentioned that changing the valve springs helped. Chris at benniesport said that it’s a 50/50 chance it happens once the megane ecu is mapped.

I kinda remember this on the odd megane 225/r26’s I’ve driven in the past however I don’t want to put my Clio up for sale and put potential buyers off if this isn’t a regular problem through out.

What’s your thoughts??

Mine doesn’t cut the ignition, it gets an odd misfire when cold which clears, which it never used to but it’s running far too rich at the moment. Needs to go back to Chris..

I am running a Ph2 ecu though as Chris advised that when I was building it. Was on std valve springs when it was mapped.

Thinking of selling mine too, don’t want to plough another load of money into it really.

Absolutely no idea. Sorry
