So I have been playing with adding resistance to the cht to bump my mixture. Messing with the mps was not getting me to where I wanted to be I wanted something a little more global. Anyway, bought a 10 dollar Bluetooth relay. Set it up so one channel was clean the other had 50ohms resistance in it. As I am driving I can switch back and forth and watch the results on the cht and AFR. 50 is really working well (this is all in addition to my 250ohm found on 73s). Now I have added another 20 ohms to the alternate so the relay will switch between 50 and 70. It ain't pretty but it's only for troubleshooting.

I added something new today. Leaving the resistance in my cht lead at 400ish. Will season to taste with the inner screw. However, now I have set up my little bluetooth switch to turn on and off a vacuum valve (EGR thingy from a Mazda) that allows ported vacuum to the distributor. Now, while cruising I can see what kind of effect the vacuum advance is having. Although I can see my vacuum on the gauge, it doesn't absolutely tell me if the advance is operating or not. Now I have to wait for it to warm up a little.
I also took this little snow interruption to actually install the bushing in the firewall for my shift linkage. I can't wait to try it. There was nothing there. When I pulled the motor I didn't even realize there was supposed to be a bushing there. |
