    You need an RRFPR and possibly 48's with that Rotax Charger. I have a set for sale. Other than that, things look good.....

    Speed is relative to setup. Fill the ride plate holes and trim the reverse bucket. No guarantees if you don't have the supporting mods.

    Exhaust temp shouldn't matter. So long as it is not tripping the alarm or sensor you are good. Don't worry about it. You aren't doing enough to matter at this point to monitor your EGT's. With your afr's right, you should be ok for now...

    Get the RRFPR - I am saying this again because it is highly important
    Get an MTX-L to monitor the AFR's - You will thank me later.

    Good luck.

    OH, Welcome to the Hulk.... Hang out and participate and talk with us. Don't only come around when you need something.

    The MTX-L is a kit that has the MTX gauge and the LC-1. The whole thing that controls and gives you the AFR readings is the LC-1 - It is called and LC-1 because it is a LAMBDA CONTROLLER-1. It reads and interprets the sensors output in voltage and has an algorithm that gives you the actual ratio we know as an AFR...... It has the ability to read multiple fuels. The sensor only gives a certain reading. The LC-1 applies a certain mathematical formula to interpret the readings for a certain fuel. The gauge then has it's own algorithm that interprets the signal and displays the AFR. This is how I understand it. Maybe I have been thinking the wrong way the whole time.
