GDE Tune .... OK, Wow!
I went out today at 3 PM and installed my new Green Diesel Tune for my WK.
I'll post some actual data later along with some "For Dummies" photos of how the install is done. It was easy. Here is my first impressions of the performance.
I got in and started up. Nothing unusual. I listened carefully and did not notice any additional noise. If it is louder, I can't tell, but then I do wear hearing aids in both ears. My wife did not notice anything either and she is a "sound hound." I have not told her about the tune up yet. That is my way of testing the "feel" of it.
I put it in reverse to back out of the drive way and first off I noticed that the Jeep started moving as soon as I touched the accelerator pedal. There is usually some mushiness in the pedal and you can tweak it a little when you back up. NO MORE. Same with forward motion. There is no play at all in the pedal, if you push it even a tiny bit, it goes.
I also noticed that the going smoother and steadier. I sometime get a tiny bit of turbo lag, but not near like it used to be. The turbo lag (if that's is what it is) is also different. Used to be it would not accelerate strongly until the lag was over, now is gets off to a smooth strong and immediate start and then there is this tiny little lag. It seems to happen on medium and fast take offs, and is imperceptible on the slow typical type take offs. My wife often complains about the Jeep being laggy. I doubt that I will hear that complaint again.
Power.... I took it out and stomped it couple of times. Very subjective test. It does seem to have more pep. I have no way to rate this. It has always been peppy. Now it is a smoother peppy. I did notice that it is more difficult to get it to go slow in those 20mph zones on Main street. Have to watch it.
Mileage.... most important to me.
I'm starting with a FULL tank and have previous records. I'm clocking mileage using my Garmin Nuvi in harmony with a Garmin Mechanic Ecoroute HD that monitors the actual engine performance through the computer port. For the next fill up I'll compare their "At the pump" feature with past records. Each routed trip is tracked and log individually.
This morning I drove to Church and back.
Recorded 16.xx on the way there and 19.xx on the way back. On the way there, the trip was ruined by a long period of idling when we made a stop....should have shut it off. It is only an 8 mile trip so a little idling makes a dent.
This evening, we made the same trip and recorded 23.xx both directions. So it appears that I will have 3 to 4 mgp increase in mileage. This is very good news to me and shows that the "tune" will be a lasting value.
By the end of the week, I'll have some comparison data to post.
So, my first impression is that the "tune" is easy to install and it does what it claims to do."
