drpep Posted June 23, 2010 Report Posted June 23, 2010 I have installed a new JPI 830 and now I am tweaking the numbers. I have the Lycoming 200hp electronic ignition fuel injected system with 540 hrs on the engine. I am currently recording chts at 70% and 2500 feet to be between 285 and 310 f. The egt's range from 1410 to 1460 Oil temps are 189 and oil pressure 72. Does anyone have some data suggesting what optimum egt's and cgt's are as well as oil temp and oil pressure? Any insight would be greatly appreciated Regards DRPEP
DaV8or Posted June 23, 2010 Report Posted June 23, 2010 I think it varies from engine to engine a bit, but I would love to know average numbers as well. I'm a engine monitoring noobie too.
scottfromiowa Posted June 23, 2010 Report Posted June 23, 2010 My POH has tables for engine at different altitudes fuel burn, HP, Speed etc. I copied and laminated (on my kneeboard) I look forward to comparing with fuel flow monitor to match numbers (fuel burn/MP/RPM) and see where this is regarding leaning i.e. 50 degrees rich of peak, 100, peak etc. I don't believe the EGT (then single probe is listed) much less a more accurate muti-robe reading. Have fun!
scottfromiowa Posted June 23, 2010 Report Posted June 23, 2010 In the green is keen...then it's all about fuel flow and speed for a given setting. Do you want to get there fast or economical...or a combination of the two...so optimal for speed or fuel flow while still operating (cylinder temps) oil temp in green as listed on your six pack.
