Seeking FK8 FlashPro input

This is tough. People who care about CARB will probably end up leaving the car stock, so from a business sense that's a reason for the race. Then there are people in all non-CARB states that want race because why have limitations with no benefits? So basically anyone who wants Hondata living in CA that want CARB approval are SOL right out of the gate.

Personally, the best thing would be some kind of arrangement like the Cobb accessport, where you can unmarry the unit from your car for smog or whatever and then flash it back on when you're back from the smog test. I don't plan on doing any downpipe or power adders...

So... CARB or not is a moot point, everyone gets the race, cars can be smogged if left stock, everyone (except those who are doing bolt-ons and worried about CARB, which is probably a small slice of the population) is happy.

How about ECO mode, decrease load values and boost for max fuel economy for those commuting and traveling?

The ECU already supports this. There are torque tables for each gear in comfort mode, and it is just a matter of decreasing the torque in the gears for economy. Again, torque not boost.

I myself would only be interested in a Race Flash Pro, for full tuning capabilities. I'm ready take my $$$. Some features I'd like to have/see are.

* Start up in +R mode
* Ability to have different boost levels preset in Comfort/Sport/R modes
* Flex Fuel
* Launch Control/Antilag
* Nos/Meth Aux
* Traction Control
* Rev Limit Control/Raised

Some very good suggestions. Looking forward to how this develops.

A very important point is that a CARB FlashPro is not just for California. Any emissions controlled vehicle in the US needs to be comply with the clean air act, and the only way to certify than a modification does not adversely affect emissions is through the CARB process. So a CARB FlashPro is for any non race vehicle in the US.

I find it so strange that the injector duty is so low while the fuel pump is nearly maxed out. A mixture between traditional Honda and British engineering?

Direct injection. It's a 4 stroke Engine. You can only inject in half the strokes. Different ECU's measure IDC differently. My old DIT car couldn't get more than 40% without impingement.

I would like a CARB option, but it makes sense to make it a race version & just flash back to stock for emissions testing. I will probably only use one of the pre-set calibrations; don't plan to dyno tune every time I add a bolt on. IC, intake & exhaust is all for me, but I know some of you guys track your cars and want to squeeze as much power as possible. Will only making a race version help with roll out time line & cost?

Technically if your car sees any public road at any time you should be getting the CARB Flashpro. Only the track only cars should get the race. But obviously we all know very few follow that.

Yes, I know 50% in the theoretical max for DI engines, but 10% is still very low.

With our 1.5T EXT and Si completely stock we would see around 25% to 30%.

The injectors are simply quite a bit larger. The DI Pump is larger as well. Keep in mind the tuned R's are seeing 100whp+ over the 1.5T's with comparable Fuel pressures. The low IDC is a blessing. The stock fuel pump gives out before the injectors even on PI cars most of the time. At least in my experience.

Plus I think the logs and dyno runs I've seen so far the IDC is definitely higher than 10%.

I think a better explanation of what is available for CARB compliant models is needed. Personally paying $1K for a device that handicaps quite a bit of the most important parameters or more is a bit hard to swallow. How about MAF scaling? Not being able to adjust fuel mass and timing on a DI car is a killer.

Will the flash pro work for the euro CTRs?

Not initially. We need to get the US FlashPro off the ground and then train dealers in Europe to do the unlocking.

Looking forward to the release of FlashPro for the FK8 Civic Type R!

Seems I'm going down the slippery slope of "race/track day car" (so the race option for me since I already have a catless system in the works), and have already spoken with Aaron at Pure Tuning Inc. in anticipation of an end of March release.

I've had this silly notion of getting a spare/second ECU for FlashPro modification ... though I'm sure it would have to be "adapted/cloned" for my car and could/would such a thing be possible??

-- Would it be possible to switch VSA completely off in R+ mode so as not to have to do the VSA switch/pedal dance every time one restarts the car at the track?

Thank You, Ed

1. We anticipate people asking for a spare ECU, although there is little benefit. The vehicle can only be keyed to one ECU at a time, so swaps at the track are out. If you did get another ECU then you would have to go down to a Honda dealer, swap ECUs in their service bay and then get them to key the immobilizer to the ECU.
2. Good point, we'll add this to our list. At this point I don't know if the pedal dance is for the ECU or VSA, and if it is the VSA there might not be anything that can be done.
As a note, is there a difference between the pedal dance and the +R 'completely off' (hold VSA for 5 seconds)? We always use the pedal dance on the dyno because otherwise you sometimes have to pull the car off the dyno and drive around the block to reset the VSA, which is a pain. But we have not tracked our type Rs yet, so hence the question if you know of any difference between the two ways to disable VSA.

The Type R seems to run less injector duration than the 1.5, but then when we put a scope on the injectors we found that the ECU will fire the injector multiple times per cycle. So I suspect that there is a difference in datalogging when the Type R is reporting net injector duration and the 1.5 is giving us the gross injector duration.
We might cover this in another post. There is a lot of science in the way the engine design and ECU operation tries to keep the mixture as homogeneous as possible.
