I recently bought a new RRM ECU. The only problem is that I don't want to have to put premium gas in it all year long. I was planning on using a switch to switch between the existing ECU and the new one. If anyone knows how you could do this I would really appreciate some help because I don't really know how to go about putting a switch in there. Thanks for your help.

 

uhm... sorry to break it to u but i don't think it can be done... i think yur getting confused with the pb and an actual ecu... the RRM pb is like an add on to the ecu... n to just shut it off... mite be kinda hard... and then to turn it on agen it myte be hard agen... but i think the increase in mpg should make you even when buying premium gas...

but i am not expert... ask rock... i am just guessing
