If I drive the same speed on the same road and tune to get 250-375 in the flat going 75 i'm good?
I get the black dial gear thing, and how it adjusts the slope of that logarythmic function thing, but adjusting the idle CO mix seems to affect part-cruise settings...
I keep chasing my tail on that.
Get a wide band A/F meter. you can infinately tune your car.
CHT will not give you much info.
EGT can be a helpfull tool tuning WOT. you would be amazed at how different each cylinder runs. Lots pf power hiding there.
I now rent out the LM-1 wideband AFR kit through the Type 4 Store..
Tuning with CHT isn't that effective..
EGT is the mega tuning tool, not just for enrichment, but also for optimizing timing..
Whats ballpark $$?
i cant find it in the search function
Its not enabled on the store yet.
I'll get it done later today after the server is finished being backed up..
Ah yes,
Always do your backups!
I've written about this before, but I installed a potentiometer in place of the
CHT in an L-Jet. I used a 5k pot beciause I had one, and I can adjust it as I
drive.
I use the CHT gauge to set it. I have found that at sea level where I live,about
1,8 k ohms gives a running temperature of 370 degrees +/-. Lower resistance
seems to produce a lot more heat. I do have holes in my engine tin, no heater
hoses, and a cutout on the starboard side for the non-existent AC compressor.
The car is quite senstive to the resistance. I theorize that I am adjusting the
mixture, lower resistance is leaner. I do not have an AFR but I think I'd put one
in a new engine, if I can afford to build one.
I'd love to know what I am actually adjusting!
