Any updates Mike? my eco wants a tune.

Hey Mike, I think I figured out what is happening. I started my truck up in test mode (hold the odo/trip button when starting the engine) and cycled through the displayed units to speed, and the digital displayed speed matches what the trinity is reporting. So it would seem that the needle on my ...

OK thanks for the info Monte.

Will likely be picking your brain a bit on a custom tune for my F150 soon as well

Hey my room mate has a new Jeep srt8 and we were wanting to play around with my trinity before he decides to pull the trigger on one.

Now my questions are, do I only have to restore the stock tune to my truck before we can use it on his Jeep? Is there a CROM update that I would have to apply before ...

Well according to my iPhone GPS app, they were both out by a good margin. the trinity was the closer of the two. My app read 92km/h, the trinity read 100km/hr and my truck speedo read 105km/h.

I ended up tuning the revs/mile to match the gps speed with my speedo on the truck just to keep mileage ...

I do not own a GPS or know anyone who does. I might be able to find an iPhone app. if i find anything out i will let you know.

I do run different size tires, but was under the impression that i could recal my speedo using the trinity. My summer setup is 285/50r20 and i set the revs/mile to 636 i think it was, and now with my winter setup 315/70r18 i have the revs/mile set to 570 iirc. Does those numbers only change the ...

Sorry it has taken me so long to reply, work etc. The PID is under performance and is named "Engine RPM(RPM)". There is also a PID named "Engine speed(RPM), and both seem to read the exact same values.(4-5% lower than the truck's dash speedo.)

Hey I noticed that the speedo on my trinity and the one in my truck do not read the same, the one in my truck is about 4-5% faster. Which one would be the accurate one?

recieved it, thanks for the speedy response, will go give it a shot now.

Thanks again.
