Before we state, I have a motronic ending in 027.
So my girlfriend accidentally bought a 153 chip off eBay that obviously will not fit my 027 1.1 motronic.
If I were to buy a 153 1.3 motronic
(http://cgi.ebay.com/ebaymotors/E30-3...em330207541249), would I be able to replace it to my 1.1 Motronic and drive happy without anything else needed?
I would like to later down the line upgrade to "I" wiring and brain for upgraded rev limit, but I am curious if I will be able to just buy the motronic and not the wiring.
Thanks. :D
