I've been patiently waiting for Hondata to impliment some sort nitrous control in the FlashPro ever since it was released, but I really doubt it's ever going to happen. However, I've been thinking of a way to rig up an "addon" so I can use the FlashPro to tune for it.

On an NA setup, there are a bunch of unused indexes in the fuel and timing maps that are reserved for boost. Could those not be used for nitrous tuning? It seems that it would just take a relay and a battery wired in with the MAP to bump the MAP voltage up into that boost range when nitrous engages. Then we can just utilize the boost area of the maps to tune for nitrous. I don't think the ECU actually pulls much current from the MAP, so I would expect an AA battery to last a long time. Any thoughts or suggestions?

 

The idea above about tying in a battery to the MAP sensor was if you wanted to use a dry kit, and wanted the FlashPro to increase fuel and retard timing at each RPM index. However, if you wanted to use a wet kit, and just needed the FlashPro to retard timing by X degrees across the whole RPM range when the nitrous engaged, then it seems like you might be able to simply alter the IAT or ECT inputs so that the FlashPro would pull timing.

 

I'm in for any updates, even though I have an MY00.

 

That's a really good concept, gernby. An alkaline AA battery may not be voltage stable enough, but I think triggering a MAP voltage offset with the nitrous switch and adding appropriate failsafes would work like a gem! Great idea.

Now we just need someone who is interested in running nitrous to make it happen.

And thanks again for the torque spreadsheet.

 

I think I have a better alternative to the battery, but I think it would be better to build a custom nitrous controller. I'd like to use CAN bus to determine throttle position and RPM. If I can find the O2 data on the CAN data stream, then I would also impliment lean protection. If it works out, I don't think it would be that hard to even make the nitrous controller progressive. In any case, I still plan to use some form of the concept above to push the MAP signal up into the boost range so that I can use the FlashPro to tune fuel and timing.

 

the flashpro unit itself can hold 2 maps. I would create one map for the all motor setup and then tweak the full throttle portion of the same map for the nitrous setup and store it. switch when you want to spray it.

It is true that the FlashPro can hold 2 maps, but it is very impractical to swap back and forth. I actually don't like to flash a map to the ECU unless I have a laptop and cable with me, since the flash can sometimes be corrupted. I've been stranded a couple times, so I'm much more selective now.

I want nitrous for daily driving, where I can flip the switch whenever the mood strikes. I don't want it for street racing, or anything like that, but just for extra power.

 

i'd just wait for the nitrous parameters to make it to flashpro. it will eventually.

 

Hondata has surprised me a few times with the FlashPro, but I really don't see how they will be able to impliment Nitrous control with it, especially soon. Even if they do impliment some features that will help with Nitrous, I don't see it completely replacing the need for a nitrous controller.

I've developed 2 custom piggy back ECU's in the past, which were much more complicated than a nitrous controller. However, I wasn't married with a child at the time...
