As most of you now know, we are using the Link G-4+ Extreme ECU. This is now the ECU of choice for our application.There is at least a half dozen GM aftermarket engine management companies. Not many will help with aviation. You do them all the same, though.
I understand that, but if they have been "around for a long time" and no distinct problems with the PSRU, then it must be reasoned that they are working ok?Not sure. I just feel better with a geared drive PSRU.
There's a number of Seebees converted and that's what drew me to the site. I am not aware of what others use their products, but the Seebee guys seem to have had a decent run.Only if you make the assumption that they actually have sales, and that the sold items are being used.
The drive appears sound, at least none of the customers who contacted me ever said anything negative about that aspect. The ECUs were stock GM ones from what I read, with code revised to remove O2 sensor inputs for operation on 100LL and possibly turn off other chassis sensor inputs which are not on the aircraft. I read where they were resetting open loop AFRs at higher power settings (leaner) in an attempt to reduce cruise FFs.Problems with their ECU setup or the drive unit itself?
This is of particular interest to me as we have the LS376/480. Titan claims fuel flows of 13 gph, but this is at a very reduced power setting, 2800 rpm. That would work out to .4 lbs/hr/hp. That will give me a burn of nearly 16 gallons/hour at 10,000 feet MSL, WOT, 3700 rpm (Max Cruise Power). Just hope we are going fast, real fast!I read where they were resetting open loop AFRs at higher power settings (leaner) in an attempt to reduce cruise FFs.
