Re: Fuel injection? Open or Closed loop?
Hogan sheet metal, the sensor is in one of the bungs, above the distributor, on the back end of the plenum.

Re: Fuel injection? Open or Closed loop?
Darrel,
I log every run and generally look at the graph after every run. I run a FAST system in open loop and like being able to review the data after each run! Nick |

Re: Fuel injection? Open or Closed loop?
That's what I've been doing except when I'm lucky enough not to have time between runs to look at them

Re: Fuel injection? Open or Closed loop?
Me too. Once I have run it, and got my A/F right on the row for that Baro, next time I run there (Great Bend, KS, Noble, don't use the same row in my VE table as Ennis, Houston, etc. Don't have to touch it. I have just about quit logging every run. Never have to touch it anymore.
In low gear, Closed Loop doesn't make corrections fast enough. If off at (for instance)7000, the ordectuon would end up at 7500, when it's referencing the 7500 cel, which needed no correction. I ended up trying to set the delay so corrections would not start until 2nd gear. I got it so Closed Loop was not making corrections in the upper gears anyway. I just put it back into Open Loop. With the IAT sensor, it's always dead nuts. The car repeats really well. Wish the driver did.

Re: Fuel injection? Open or Closed loop?
More thoughts......
Since I most likely can't win a heads up based on performance I should quit worrying about getting every last hundredths of ET out of my cars. I should just get them tuned to where it's consistent and leave it alone. Agree?
