So as I am sitting here with the flu and cold in full effect sipping on my nice warm apple flavoured neo-citran, I find myself in a meditative state of mind. Looking out towards the many tasks that I have ahead of me and struggling to understand how I ever got to this point.
What started as a conversation with my better half regarding an old BMW that isn't too fancy and that I could park on the street, soon became a garage only drive, with electronic fuel injection accompanied by a laundry list of parts that I have amassed for the next stage of development. I find myself wondering why... why do I feel compelled to jump into this?, is it ego? is it curiosity? is it bravado? what am I trying to prove? and to whom am I trying to prove it to?
The reality is that I feel enabled by the folks on this forum. And truly enjoy sharing what little time I have trying to help others. I think what I am trying to say is thanks to everyone for your support on this part of my journey. It means more to me than you may think.
Now that I have all that touchy-feely stuff out of the way. I think I will close out this blog, as the initial scope of putting a Sniper EFI on a 02 has, at least for me, primarily been fulfilled. The knowledge that I have gained has been invaluable both as a car enthusiast and a data jockey.
I have been fine-tuning the system, and for the most part, it is working well. I hold myself to a high standard, and by that measure, it wasn't a complete success. It starts drives and stops well. The shortcomings of a TBI based injection system perhaps are exaggerated by the small displacement of the engine. I do not doubt that it would be an excellent fit for an M20. I have primarily tamed the idle issue by essentially digging a hole for it to sit in. On each side of the hole, I put a very steep fuel and timing curve that "forces" the idle to stay between 850 and 975 RPM when the pedal is less than 2%. Kind of a hack solution, but a solution nonetheless.
Before I decommission the setup, I will post my log file and tune file for anyone wishing to pursue a TBI setup further. Perhaps Holley will come out with a TBI that is more suited to smaller displacement engines. I will be starting a new blog on the conversion from my existing build a new one based on the familiar 3 series manifold. I think it was a good rule that I will post stuff there if anything interesting or new as many others have done an excellent job focusing on the fundamentals of the megasquirt conversion.
Being a data cowboy and learning from this journey my intent is not to make enormous power (just significant power), but to essentially create a data-gathering platform that I can learn from and perhaps contribute in some way to the 02 community. The ultimate goal is to inspire others to tinker with stuff (not just cars). I will fail, I will pick the wrong wire, but ultimately I will get through whatever hardships I may have.
I want to do some crazy shit as well, even more hair brained than this one, just to see if it would work.. why? ...because life is truly too short.
