no disrespect, I completely understand why you want to do as much as you can yourself, but when it comes to something as specialized as mapping a car, fair enough have a go at mapping a cheap engine build, to learn the basics but WHY fuck about ruining a good engine trying to map it yourself? a little bit too rich or too lean will easily kill an engine, and from what I have read you have nowhere near the knowledge or equiptment to do the job 100% corrctly, when its somthing like this 95% correct IS NOT GOOD ENOUGH
