    Where do I start,

    Installation was a breeze following the guide attached, just note that the included saab air temp sensor its m12 as stated on the individual listing for it. Small bit of wiring later and I thought I was sorted! No such luck she cranked but I was getting no spark and no fuel injection. Emailed the diyefi email and Jamie had a look over my tune and sent it back to me, no luck! So after some troubleshooting Jamie instructed I jump the Crank jumper you can see on the back of the board inbetween the main connector pins and I was finally in buisness! Started straight up.

    All in all I can’t recommend this kit and Jamie enough, it took a bit of work but his dedication was amazing!

    TLDR if you have a 1.6 1996-1999 mk1 UK model (defined by the slightly different surround to the rear numberplate and unfortunate 88bhp tune and cams) you might need to perform this step outlined above.
