Edge Pulsar owners

Just installed the pulsar on my truck today. I have bigger than stock tires and hate the pedal lag programmed into these trucks. So i went the pulsar route instead of a PC and speedometer calibrater. The pulsar solves both my issues cheaper then both mentioned above ideas.

My only gripe so far is mounting location in 2017 2500s. It’s a tight fit between mounting bracket and A/C lines. I had to bend the line a bit to make room. There isn’t a clearance between A/C line and PCM connection that i would like. I had enough room to slide a section of wire harness insulation over the A/C line to keep it from rubbing connector as well as help with heat on the connector. Hopefully it will be sufficient. Maybe someone has a better solution. Picture is below.

I will be driving from south Texas to Massachusetts next week, 2000 miles. I will be tracking fuel consumption and drivability. The terrain changes drastically as you drive north east so mpg will not be consistent along the whole trip as gravity sucks and will going through mountains and city traffic when i reach New England. I will log mpg for each fill up and section of route and elevation. Once i have the data i will determine best way to present the information.

I will either run in economy or tow without MDS. With my tires and size of truck MDS hardly comes on due to tire resistance and vehicle weight (7895lbs, roughly). I might have an extra 1000lbs of people and cargo.

Just installed mine in my ‘18 PW! It fit well! I was a little confused with the mount, but I finally got it! It looks a bit awkward, fit it fits and it works!

I set mine to economy mds on, 34.6” tires, factory gears! My PC is set to city +4! I ALWAYS run 93oct! I’d love to see another mpg, but we shall see!

I’m happy so far!

Running in Economy, MDS on, Ive been seeing a continuos rise in my average MPGs! A steady gain of .9 so far!

I travel 19 miles each direction, to and from camp! Home in the morning, back to camp in the evening! Cruise is set at 65, corrected to a 34.2” (35 12.5 17 BFG KM3)! The pedal commander has been backed off to City -2!

Performance doesn’t seem to have change(butt dyno!)!

Happy with the investment!

I am looking into shutting off the MDS to see if it makes a difference when going down a really steep mile long hill in 4x4 Low in 1st gear, no throttle applied. The trucks gearing and compression should slow it down enough, but I find myself tapping the brakes more than my previous truck, a 2006 Tacoma. The truck feels like it holds, and then releases and speeds up. Wondering if this is the MDS kicking in when descending down the hill because I am not applying any throttle.

Do any of you have a similar experience and will the Edge Pulsar fix this you think by turning off the MDS?

I will say that I was skeptical at first before I made the purchase of my pulsar. I’m pleased to say that it has worked out well for me. I have a ‘17 on a 6 inch RC lift, 20x35s KO2s. I was averaging on the ole truck computer before hand between 14.5-15 MPG (13.9 last check before install). Usually driving 75 MPH in hill country of Texas every day.

Fast forward to installation of pulsar and running all the different settings weekly and/fill ups to test MPGs. I eventually stuck with the performance mode w/ MDS off all the time. I average the same if not better in this mode as I did in any other mode. My truck computer averages 15.9-16.4 currently. I know the computer is usually about a +1mpg difference most the time, but still pretty good numbers for my truck.

Next event to make me feel confident in my purchase. Now.....I’m in the military and took some leave to go back home to Arkansas for a couple weeks. I don’t know if it was the difference in state posted highway speeds , altitude, humidity or mosquito population or what, but my truck averaged at one point 18 MPG!! I was shocked, because as I was driving across states, I through it in economy mode and wanted to see how it would perform. Well, just like before, I started dropping MPGs, so I kicked it back into performance mode. It went back up of course.

Anyway, I know this was long, but hopefully it helps someone out there on the fence like I was. I have no complaints so far and it makes the truck fun to drive on top of the added fuel MPG benefit.

I would not want any tunner that does not remove the speed limiter, I thought they all did that.

So far, no complaints on my end!


Short term, eco added almost a full mpg!(9/10+)every 30-40 miles I gained 1/10! Was hoping to see that one more 1/10, but got into fall/winter gas mix at the pumps(always hurts 2-3mpgs)! Towing the Toyhauler home and running 4x4 on snowy, icy roads!

my winter average was 8.6mpgs in economy!

im going to run Performance now that my toyhauler is hauled back to its seasonal site!
I’m up to 9.8mpgs after 133 miles!
My driving style would be called “spirited”! I’ve also replaced the 35” Duratracs with the 35” KM3s!

I’m hoping to see 10-11mpgs!

It’s kinda funny, my “economizer” is a WS6 that I roast off 3-4 sets of back tires a summer! It averages 21-24mpgs!

Why would you want to go faster than the speed limiter in this truck - that’s stupid! Go buy a car for that ****

I like the Pulsar for what I paid and what it is. It really does the job.

I'll be ordering one soon. I have a 2018 and started looking at these almost 2 years ago. At that time there were still some sporadic issues and figured I would be better off waiting. Now I can adjust the tire size as well it will work fine for what I want. I don't need crazy performance out of this thing as I have a Challenger Scat Pack for that. I just want a little more performance as the Ram does lag at times and the ability to disable MDS without pressing the gear button is a plus.

As for removing the speed limiter, I don't get that. Rams get rather unstable at over 100mph and I really don't do that anyway. That is what the strip is for and the Ram isn't something I would ever run there.

I have had 2, one on each truck (17&19 classic) and I really like them for what they are.
The MDS shutting off was a issue,(not sure if it still is) but I just automatically hit the gear buttons on the steering wheel to 8 and NO issue.
If you dont have one I recommend a pedal commander or equivalent to complement the Pulsar

i got the cheap 9 drive and man that made a huge impact- the 5.7 is pretty lively with the throttle lag removed

Hey guys. Just about to order my Pulsar but I’m confused about something. I see a lot of guys talking about how great it is to adjust power levels on the fly, and a lot of guys seem to be running the PC in conjunction with the Pulsar. That would be me as well as I already have one on the truck and I love it.

My question is, if you adjust the Pulsar on the fly, it doesn’t have any affect on the PC correct? I know if you try to change the PC on the fly it will throw all sorts of codes from what I’ve read.

And I would only be interested in running it on level 7/8. From what I’ve read in this thread a good PC combo setting is about City +4. Is that still an accurate statement? Just want a good starting point.

And fuel requirements. 91 fuel around here is tough to find and very expensive. Anyone running level 7/8 on 89 octane who can share their experiences?
