Dyno tune

[rainman]

Drop my 05 rocket 3 off last weekend to be Dyno tune Having a problem of it staying tuned
The guy says he has it tuned but then checks it the next day and it has changed
It is either running rich or lean this has happened each time he has tuned it
Does anyone have any suggestions on what might be causing this

I'd try reloading the tune. Then check the TPS.

Steel I checked the tbs before I took it to him I will be picking it up tomorrow

[Steel]

Did he tune the ECU, or did you use a Power Commander? Either way, I'd try reloading the tune in the ECU.

[rainman]

Using tune ecu
grom what I understand from him is that when he reset the adaptation is when everything change
O2 sensor off
Maple and tps sensor reads like they are supposed to when he was tuning

[rainman]

I'm gonna run this tune for a little bit to see how it is if I don't like it I'll change it back to the tune I had

We went out for a good ride today over 200 miles the rocket did good ran smooth and plenty of power but the only thing is my gas mileage went down from 33-34 mpg to 27 mpg

I've never quite understood why youse 'Murcans' worry about your MPG figures. You pay for a gallon of fuel, albeit the smaller gallon, what I pay for a litre! Just another of lifes little conundrums.

Grumpy Old Codger l don't really worry bout the gas mileage just letting people know that I had it Dyno and that my mileage drop it's all good 😃☔

[rainman]

Update of the update went out for another ride today and my mileage is back up to 33-34 mpg

Just another of lifes little conundrums.

I wonder what difference there is in electricity prices?. Time to start making Hydrogen I think.
