jaje that looks like a M coupe in your avatar? I used to have a boston green 99 with a half cage in it.

to OP how does this mod compare to turning off the Eco mode and a heavier right foot?

I'm curious what error message you are receiving then. I certainly haven't encountered any error messages when I have both pedals depressed, and we have the same vehicle.

Re: Diesel Lag

I don't find modern diesel engines laggy at all but then I'm just driving to the grocery store and such.

I'd be interested in a tune that gave me a lot more actual hp, but a device that electronically pushes the pedal down for you is pretty unappealing to me.

It would get a message on the EVIC stating Service Electronic Throttle and the throttle would be cut off completely as well as the brakes seem to lose the power brake function. Kinda freakin scary at the time. After I took my feet off the pedals in a second it was back and error message was gone. No DTC codes (or at least I didn't check them). Since I stopped using both feet in the Jeep it I never had this issue again.

Actually it's my old Spec Miata racecar I sold when I moved from KS to NJ last year. I'm now running an Exocet (based on a Miata) with NASA NE and also the TT Director here. Do love M Coupes though - never bought one as they are much rarer and more expensive than a Miata.

I installed a Throttle Sensor adjuster from BD diesel Performance on my Dodge and eliminated the issue.

Once I took delivery of the new JGC, I waited two weeks before I could not resist getting one for my Jeep. Installation took about 10 minutes, and she was ready to test drive. The Throttle Sensor has (3) settings.. stock, 50% and 100%. Basically, do you want stock, mild, or wild. Since I am the primary driver, I set it to the 100% setting. This little box, really make the Jeep rip. Really amazed at the difference it makes.

All that this device does to connect into your throttle and advances the throttle sensor accordingly. Simple... dealers cannot detect it, therefore, it does not void your warranty.

I let my neighbor drive it (Local Dodge Dealer Manger) to see the difference, and he was amazed. He said that it almost felt like the Hemi. Since installing, I lost about 1 MPG in the city, and have the same on the highway.

Anyway..... really love this thing and wanted to be sure to share with the group. See BD Diesel Performance dieselperformance.com for the Throttle Sensor Booster. You will not be disappointed.

Wow. Yeah, I have never experienced that while holding the brake and accelerator at the same time. Your experience was somewhat ironic given the whole point of the maneuver is to develop more power.

This is exactly what happens to me 2 days ago... See troubleshooting forum under service throttle sensor...
I think I may have used both pedals at the same time and it didn't like it at all....... Dead pedal until restarted...!

Re: Diesel Lag

Yeah - me too - I left foot brake and if I'm not quick enough with the footwork I get the "Service Electronic Throttle" message which goes away after a while, but will later result in the "Check Engine" light staying on. I am not a big fan of electronic throttles, and the pedal lag that comes with them.

Re: Diesel Lag

So does this mean that in theory at a boat launch, disengaging the E-brake while keeping your foot on the brake and then proceeding to give it gas to keep it from rolling will cause it to throw an error/code?

Re: Diesel Lag

Yes it very well may, but if you have the hill holder function engaged it may not roll back on you.
I have a boat also and won't know till this spring how that works for me too.....

But I have learned you can't ride both pedals at once.. It does not like that.....

Re: Diesel Lag

Mild use of the accelerator whilst holding the foot brake down doesn't cause any problems. I do it every time I more our boat or caravan as our driveway is steep... and also at the ramp.

Dragging the foot brake as you move is a different story, as is giving it bulk throttle.

Cheers,
Steve
