thanks, dropped to 11 for my morning commute and she worked solid, seems like good power and boost increase. I tried to film a 3rd gear pull on the highway with my iphone but I kept getting DTC kicking in at 50mph boost on my p3 gauge showed 18.3psi. I think I read somewhere that boost on the gauge is actually higher than the engine is seeing?

I want to thank Shiv and everyone else who works on their PnP meth kit. It truly is high quality and well thought out. I did run into one issue that I think is worth mentioning with anyone who has a Injen DCI. Placement of the meth jet interferes with where Injen relocates the power steering reservoir. I had to literally pull apart the two hoses under the power steering reservoir and slip them around the meth jet elbow. Maybe if I flipped the Meth pipe around it might have been better, but I got it to fit this way so I decided not to try flipping it. The other very Small issue I had was that the positive battery lead connector was to small to work on my battery connectors, so I just changed that. Most time consuming part was looming the wires together with the supplied wire loom wrap.

Whenever an injection mode change happens, I think it would be awkward at best if Autotuning of Map1 had to re-learn everytime it switches maps..........just putting that out there.

So is it fair to say if we can expect that when the Procede does not see meth flow via input from the IFS-30, the tune has the capability to automatically switch injection modes and progressively transition from the Meth map to map1, but if we manually switch to Meth Injection mode and meth is flowing, it will progress to the Meth Map.
In this setup.......Map1 always being a "Autotune Mode Map" and Map? being a "Meth Injection Mode Map".

The DTC map switching should only be for switching between Map1 - High MPG Map - Valet.
Methanol mapping should only be accessible via another CANbus enabled switch which will change Injection modes.... which will then in turn, automatically enable the Meth Map.

Please don't flame me as it is just a thought which I think would be ideal but is this feasible at all or have I confused myself??
I absolutely agree on the persistant auto-tune settings when switching injection modes (not when manually switching maps) but I don't think I'd want the injection mode to be automatic.

The flow sensor integration should only switch maps (defaulting to map 1) if I turn the injection mode on, and should auto-tune map 2 only in this case. It should stay in the map I selected if injection mode is off and auto-tune that active map.

I would still love to see the injection mode switching also support arming/disarming the methanol kit hardware (through one of PROcede's outputs and a universal relay???) This way you would have one button on the dash to press to turn on injection logic in the PROcede and power the pump/controllers.

Hey Shiv - how high is "in car injection mode switching" on the priority list for you guys?

Since I got my kit installed I've been running with injection mode ON constantly, which is cool because it auto-tuned map 2 settings on meth to 15.9psi and 0IC At the same time though, I've been running off methanol at the map 1 default settings of 13.5psi and 50IC

I recently had an issue with the solenoid so I turned OFF the injection mode and my map 1 auto-tuned to 15.1psi and 0IC. Would be great to be able to take advantage of both these auto-tuning capabilities!!!

Should be taken care of with the next firmware update. Thinking about introducing a Map3 which would essentially be Map1+Map2 progressive. This way you can leave your injection mode value in the user adjustable all the time. But to make it funcitonal, you'd have to mapswitch over to map3. So map1 and map2 become standard injection maps (pump/pump or pump/race) with full autotuning. Sound good?

Does it affect people that have a on/off switch in the cabin....Essentially my meth is turned on by a on/off switch

My question is, If I run meth and it is always switching over to map 2 then if I run out of meth and or turn it off map 1 really has never fully auto tunned as it is switching to map 2 before it learns?

So if we don't turn the meth hardware on and there's no flow in effect it's like running map 1 only, but if you turn on your meth hardware and the PROcede sees flow it will transition to map 2 (with no need to change injection value/mode)?

As long as both are autotuning (map1 when there's no flow, map2 when there is) is there really any reason to mapswitch manually? If I'm understanding this correctly, it sounds perfect!

Yes. But currently in progressive meth injection mode, you will only autotune when meth is flowing. So in the scenario above (in progressive meth mode but without meth flowing/turned off), you will not have autotuning active. Have a dedicated map for progressive meth (map3) will solve this.

That sounds like a good idea but what happens when you switch over to Map3 but don't have meth?
Will the Procede detect this "No Flow signal" situation via the 5v Blue wire from the IFS-30 and automatically switch back to Map1/Map2 ?
Ideally, it might also be a good idea that Injection Modes change automatically dependant on switching between Map3 and Maps1-2 and/or Meth Flow Signal.

If Shiv introduces a Map3 which is the dedicated Meth Map, that will arm/disarm the methanol kit via input of the flow signal from your failsafe. 0v=no flow, 5v=Meth Flow. So it won't be necessary to have a seperate switch, as Map3 is your switch.
As for Injection Mode switching from Standard to Meth...........I still believe that it can be dealt with automatically dependant on which map your switching to. Having to remember to switch Injection Modes manually just adds to the confusion.

It's a good idea but the only thing is that you loose your autotune settings for the other maps.

I also agree on the confusion on the switch for injection mode. One map meth should handle the meth flow, injection mode, and everything associated with methanol. Might have to have this in the new software.

It might be good idea to persist the auto-tune on map switch. I am not sure what the advantage or resetting is on map switch, but am sure there is a reason its like that seeing how well thought out this PROCede tune really is. I'd be curious to know what the rationale was though.

The way I'm reading this is that when you're in map 3, it switches between the actual map1 and map2 that you've defined in the user adjustables based on seeing meth flow, so there's no "actual" map3.

Therefore if no meth flow (either because you don't have a meth kit, you haven't hit your kit's flow psi yet, or something's wrong), it stays in map1.

I think you still need a switch to power the hardware, but with what Shiv/Calvin describe you won't need to switch the injection mode. In my case I would always run map3, and control whether or not I wanted meth flow by just turning on/off the meth hardware via my homelink button

I don't think you lose autotuned settings unless you manually switch maps with DTC button. In this scenario, autotuning would be active (if turned on in the user adjustables) for all maps in all situations.

Then again, what do I know

I hate it that everytime I switch maps I lose my autotune settings and I hope if this can be changed to keep it persistent.

Once maps become persistant via DTC map switching, it would be a good idea to enable an Autotune Reset button via the User Software............for those times when you want to start autotuning from scratch and allow the Procede to re-learn.
