Piggyback are old and dated. Engine management can’t change the whole car so much more responsive with standalone. Stick out the extra few quid it’s worth it. @RobSR can supply and/or fit/map Haltech, link, syvecs and other ecus.
You can convert the stock dizzy to 12-1. And remove the cam signal. And/or try replacing the dizzy cable with a shielded wire earthed only at the ecu end. Give me a message if you want any help
