nobody is going to show me how to map a car as they will be doing themselves out of a job so theres only one way i'll learn anything.
how does the bottom pulley work out with the position sensor? is there one for a det available?
hows the black legend coming on jackiefan?

Emerald gets rave reviews from everyone I've spoken to about it, admittedly I know know anything about mapping ecu's.

Going to be running Omex in mine when it comes to it but that's just because I got a good deal on one

The Crank angle sensor wheel thingy from Omex is just a disk with a small 10-15mm hole in the middle of it, I guess the Idea is you then get a machine shop to match it to the OD of the crank pulley then tack it on. You then rig up the actual sensor (?halls device?) off the front of the block using mecano or something. Its a one size fits all solution although I'm sure there are some clever sods out there that have found other ways around it.

The MKI is coming on, all be it rather slowly (I just don't get the time to work on it). Got mostly S13 parts for the front end sorted and painted, all the front bushes are done. Just need to get the manual rack back from my old man so I can get it rolling again then it's off to get a cage fabbed up (when I can find someone to do it for my for sensible money). I'll update the project thread as soon as I've got it to a point I'm happy with.

this is what i did...



made up a spacer ring and machined an omex trigger wheel blank to suit




pic shows the original crank angle sensor bracket on the cam belt cover, but although it felt stiff, it vibrated and caused a missfire, so a beefy bracket was bolted to where the water pump used to be (my car runs an electric one). just ensure the crank sensor bracket is built like a brick sh*t house or they can cause issues
