FlashPro Flex Fuel support

[Mestiso863]

Thank you for this.

For anyone else playing along with the wiring diagram decoding ring/hunt game, Honda refers to this as MAF/IAT1, and MAF/IAT2 according to them is on the intake manifold. The white wire Hondata calls out is pin 3, and traces back to fuse B21 in the cabin. This is the same fuse that SiriMoto recommends for their kit install by the way. Apologies for the odd screengrab, they don't make it easy to get everything in one go:

Where were able to find this diagram? I've been trying to find wiring diagram for the all the grounds

I’ve always used full power 1st 2nd but had to lower the slip value to 1% on Hondata traction control because of excessive front wheel slip from all that added torque.

You do realize optimal slip is about 5-6% right?

Doesn’t matter anymore since My TC is now set in the Power Metrics stage 2 tune.

full installation and how to plus review of sirimoto flex fuel kit with hidden "integrated" gauge display in the engine bay with a waterproof box. even more torque now on top of the recent prl "triple threat" setup (hi volume intake, titanium turbo inlet, and charge pipes)...

Currently running the OTS Flex Fuel tune with PRL HV intake and front pipe. Mixed to E27 and car is running flawlessly. Fuel pump is definitely near the limits.

Logs attached for anyone who's curious.

@Hondata will there be an update to the Flex Fuel map soon? Also wondering about the PRL intake, if it will be available as a mod soon.

 

[Hondata]

If the intake does not alter the AFM reading then it does not need a mod. The only intake the does need tuning is the eventuri.

Don't really like the idea of splicing/tapping the factory harness for the Innovate install. Would prefer PRL's kit since a lot of people seem to be keeping their gauge under the hood anyway.

@Hondata, thanks for all the info. Just to confirm a few things.

It seems like if you're going to go with flex, you're better off having everything else stock due to the factory fuel limitation, correct?

Are there more performance gains with flex + FBO if there wasn't a fuel limitation, or is it still marginal?

 

[Hondata]

Ethanol will still give gains with the stock fuel system, but not around peak torque where the HPFP is at max flow. At peak power the fuel pump typically has fuel flow to spare. The difficulty is that there is a fine line between making more power over pump gas and reducing air charge to keep the fuel pump from running out of fuel. As far as FBOs go, most don't make any power or have a secondary effect (lower temperatures in some circumstances), so the only one that makes any difference is the downpipe. And that is a component change not without negative effects.

@Hondata, not sure if it’s something you were already planning to do, but it would be helpful if you made a video on how to read WOT pull logs. For example, what are the primary sensors I should be looking at, when should I be concerned, etc. I think it would just educate the community as a whole.

hi guys quick question has anyone experienced a few beeps from their horn prior to starting up the car? just finished installing the sirimoto kit today and looks like that is that is the only thing ive ran into, i just went to check my connections and disconnected and reconnected everything, thanks for the help and much appreciated

 

[ruddyrid@procivic]

Just an update in response to @Ashxsi post and in case anyone comes across this in the future, found that the alarm was accidentally disconnected during install. He was able to plug it back in and was good to go.

 

[ayau]

@Hondata, can you comment on power being potentially reduced when the ambient temps are lower (e.g., less than 60F)?

Since it sounds like the fuel system is already close to being maxed out on a completely stock car, does adding flex/E30 add any additional risk? For example, is there the potential risk that the engine will run lean due to not being able to supply enough fuel? Is the tune able to quickly compensate for the lack of fuel to reduce the engine from running too lean?

How difficult was it, to install this gauge, under the hood? I'm torn between having it inside and visible vs. under the hood. I'm guessing it's not something to always look at.
