Suppose KE- jectronic is ok but im sick of buying bloody metering heads dont seem to have much luck with them. At nearly £100 a time second hand it gets expensive. Plus EFi seems to be more tunable from what i can gather. Am in the process of converting my mates xr2I to 2Ltr zetec and he is getting ideas of going all the way and turboing it. So could order two lots at the same time. The mega squirt seemed quite a good setup. i also read u can buy it in bits and solder it together yourself. Whats that all about?
