was wondering if the autotunes aggressiveness will be ramped up much faster with heavy knock events and drop in timing (e.g. meth system failing) or if it will still be subject to the 3-4 partial throttle pulls to bump it up.

Just to clarify, autotuning is a scalar adjustment to the currently active map. And that map, in the case of progressive methanol use, will range in boost/timing as a function of meth flow. You will NOT be relying on autotuning to make the map aggressive when meth is flowing and less aggressive when it isn't flowing (or fails).

Autotuning is simply a substitute for manual custom tuning. Think of it as a full time tuner making relatively small adjustments all the time in reaction to different driving conditions and driving characteristics.

So more along the lines of switching between an M7 and M10 nozzle and changes in the meth mix while on a methanol-specific high boost map.

I have a DO basic kit with no failsafe or flow sensor, but I do have the low level sensor that will indicate when I am out of meth and at which point I can swap out to a lower map or refill the tank. I am not sure if the DTC map switching will work on the fly for such a situation, as I do not have the unit yet!

you should add a flow module... they aren't expensive..

The coolingmist flow sensor is 110 or so IIRC. Are there cheaper options? I do not want to install the CMGS or VC2 from cm.

edit - missed that link below. That unit looks very simple and easy to implement. Rip out the current pressure switch, replace with this, secure with double sided tape or zip ties in the engine bay. Run flow signal to Procede, issue resolved. I'll look into it for sure later on. I bet if the dash boost gauge ever comes to fruition i'm sure monitoring flow would be right up there with it.

Does this flow sensor replace a basic hobbs switch based pressure switch or works in conjunction with it? I am looking at the diagram and am confused as to where that green wire goes.

considering the benefits a flow module adds, it isn't a lot of money..

i don't know of any cheaper options but i plan on using the labonte module since it is what shiv uses/suggests/sells w/ his kit.

Can't wait for autotuning maps...I just upgraded my M5 nozzle to a M7 nozzle and hooked up the other M10 nozzle in preparation for NO2 when Shiv comes out with it!

M7 meth nozzle will always be controlled by the meth controller as a function of boost...If you choose to install nitrous is when you install another meth nozzle rated (M10) with solenoid and this nozzle will then be controlled by the Procede on when to spray along with the nitrous nozzle...They will work in conjunction with one another, both being controlled by the Procede tune

works with the current boost switch. What I did was run the blue wire to the procede harness. For the power to the unit I simply tapped into the wire that goes from the pump to the boost switch. Then simply ground the flow sensor to whatever. This way when you hit xx psi, the boost switch clicks, turns on the flow sensor, sensor feeds the signal to the procede and its all gravy. Real simply, install will take you 30-45 if that.

And now the Procede will use the meth flow as a failsafe to kick down to a "safe" map, right?

I saw the DIY on the Vishnu site, does not look difficult at all. Looks like I don't need the 12V output from the failsafe, just the 0-5V flow sensor?

The Procede currently uses the 0-5v analog flow signal in a feedforward system to induce extra boost/timing.

This approach is more driveable, safer and just better tuning than simply using a 12v output from the failsafe to trigger a discrete map change to a high output map or to a valet mode. That's so 2009.

That's the second time you said that. I have a 2009 approach to tuning I guess.

The new autotune maps haven't been sent to beta testers yet.

Hi guys,
Just a head's up.... i've promised to spend this weekend with the gf (with the exception of the few hours at the dragstrip yesterday which I still don't know how I pulled off). But I have new maps/firmware ready to go for the private beta mailing list. I'll send them out tomorrow along with documentation. Yes, an early stage of autotuning and launch control (for 6AT) will be included. It will be explained in the email. Once I get enough feedback, I'll release a more advanced stages of them. I'd rather not do everything at once since I can only absorb so much feedback in my thick head at one time

2-3 weeks for the upcoming batch. 10-12 weeks once that is sold out. We are, quite literally, making them as fast as we get the parts.

To clarify for myself, this will actively autotune based on the map and current conditions it reads to optimize the performance of the tune. You set the map based on whatever mods you have on the car. The tune does not automatically detect what mods you are running and adjust. Correct?
