Help Teaching Wren SS ECU with Jeti/Duplex DS 24 TX
Please help!!
I have a Wren SS that I have had for years that works great. I upgraded my radio from a Futaba 9C to an amazing Jeti/Duplex DS/DC-24 and for the life of me I can not get the ECU to read the throttle position properly. I have gone through the teach process 20 times, reversed the throttle, changed batteries, and everything else I can think of. It seems like a simple process but when I am done it doesn't say "ready" like it's supposed to, I either get a message that says "Sticklo!" or "starting". Advancing the throttle will start the starter like going into manual cool down mode, but NOT initiate the start sequence. I can look at the pulses on the home screen and they don't change when I move the throttle trim (digital), but do when I move the throttle stick. As far as I know, no failsafes or throttle cut/hold are set up as this is a brand new radio.
Any help you can provide or suggestions would be greatly appreciated.
Thank you
Anthony

Wren SS ECU Issue
BTW, I am not sure which software version the ECU is, I am sure I have not updated it in years. I just turned on my 9C and it worked so I didn't mess with it. I am not even sure I know how to update it with Wren USA service being gone and all.

Just a thought, try reducing throttle throw to 80% before doing the learn sequence. 80% in Jeti is equal to 100% in some other devices. Not sure if the older Xicoy ECUs require this.

Have you looked at the servo monitor on the TX (or with a servo plugged into the throttle RX output) whilst moving the throttle and throttle trim?
Is the trim responding correctly?

Siclick,
I think you are on to something! I plugged a servo into the throttle port of the receiver and the trim does NOTHING! The stick will move the throttle, but for some reason I have no throttle trim. Somehow I must have disabled it. I have to figure that out before I try anything else.

Thank you for merging the two.
I got it figured out by the way. Appears by assigning controls using the wrong utility, i had "hidden" the throttle trim from the receiver by creating a new channel. Rebound the receiver started from scratch and everything works perfectly now. I would not have imagined the trim was the problem.
Thanks for the help everyone.

Danny was right on the money, I assigned the throttle trim but did not do it in the correct utility. As it turns out, all I did was confuse the transmitter and turn the trim off. I am new to Jeti and still amazed at how sophisticated this thing is! I am used to manually doing thing that the transmitter already knows how to do.
Thanks again to everyone that provided suggestions, you definitely put me on the right path!!!
