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.

On L-jet crap I'll added variable ratio potentiometers on both the CTS (your CHT) and IAT circuits.
Big changes with CTS and small adjustments with IAT. I'd adjust till a bit on the rich side and then lean out with small adjustments with the airflow meter spring tension. With patients and practice I could dial in a L-jet powered 280Z pretty close... I know you're D-jet and it's different. Don't know if you're even using an IAT but it works the same way... Used to buy the little puppies at Radio Shack for less than $5! |
