Anyone here running Banks Pedal Monster to counter diesel turbo lag?

[SSingh1975]

Topic..interested in getting this but not sure if it's actually helpful or not. Plus its $300 so not exactly cheap for a "trial". I have a stock rubicon with factory 33s but I work from home so most of the drive (as of now) is around town/short commutes with a lot of traffic lights/stop signs etc.

I have the Pedal Monster. It doesn't get rid of the turbo lag. It covers it up.

So, not on a gladiator, but my friend has it on his Ford Diesel and says it takes care of the turbo lag. I would assume it would do the same for the Gladiator.

I would be curious as to how it could "cure" turbo lag. Turbo lag is caused by not having the exhaust flow to create boost. Anti-lag is the only thing I have ever seen that actually helps by dumping raw fuel into the stream, but I can't imagine that's easy on the turbo. You can remap the boost tables, but that isn't going low lower the actual RPM that boost is available, but can at least map all available boost. The only other fix is to replace the turbo with something smaller that spins up quicker or something more efficient.

There is an on ramp I take leaving work to get on I70. If I cam merge quickly, there is not lag and I'm up to speed. But if I have to sit and wait for an opening. I got lag. Unless I brake it.

There are two different things to talk about here: turbo lag and throttle input lag. None of these pedal controllers (I have a Hike-It) change anything about actual turbo lag.

But ask the 3.6 (non-turbo) owners about their experiences with throttle controllers. Best guess is, Jeep programs in a little time lag between pressing the pedal, and actually delivering increased power at the engine (presumably for slightly better MPG on the EPA test cycle). Throttle controllers all seem to improve this, perhaps by directly editing the delay out, perhaps by delivering a pulse that simulates a quick stab at the throttle, perhaps something else. (I haven't found any direct evidence like oscilloscope traces, just lots of first-hand reports including my own.)

First hand experience: Hike-It reduced the perceived lag between pressing the pedal and increased power delivery. It's not subtle, and when I remove it for a dealer visit, the increase in time lag is immediately obvious. This is even on the "Eco" setting, which actually reduces the amount of power you get for each degree of pedal movement. So it's not just some placebo effect of remapping the pedal movement vs power curve.

But like above, there's nothing it can do to change the time needed to spool up the turbo and deliver boost (and that actual lag is present and obvious in the usual situations on my diesel). They just seem to improve the input lag.
