not to get back on topic
but I installed a SW chip (and a Fabspeed pre-muffler) on Thursday and Sat ran with them in our local PCA auto-x. The car definitely felt more alive and I was spinning the rears more than usual. Chirped 2nd on a couple of launches, and I am really not that aggressive. Did I measure anything? No. I told onlookers I did a 450hp E85 tune to see if I could get a laugh. My engine is kind of beat inside so I am not sure it would even be useful anecdotal data. (worn valve guides, pitted cams, oil leaks… the usual)
I also replaced the fuel strainer from the tank, although the old (36 yo) one did not look terrible.(which is good news)
re: things I don’t understand - I have no idea how you squish a fuel map into 8k of code. Obviously this was not written in Java
You have an idle switch (use idle map?), a WOT switch (use WOT map) but in-between there is a lot of ground (isn’t there?) Amazing stuff however it’s done. Kudos!
Starting seems a little better (fewer cranks), idle is perfect and stable, and it feels more like a good set of carbs now without that hysteresis I generally associate with EFI. Crisper, more lively? Hints of gasoline & pilsner? (
Maybe) The top end seems better too. I don’t want to have to shift bc it is pulling so eagerly now.
Niggles? My anti-static wrist band’s elastic is failing just to remind me that I am getting old. Time for a new one I guess. #sigh
Overall the directions were clear and the process lacked drama - which is a good thing(tm) and the thing makes a noticeable difference, whatever that means.
