Did you try testing the 15Amp #6 washer fuse in the engine compartment?

Washer stays hot after ignition turned off. Checked already.

We use the white wire on the MAF/IAT2 harness since it is right there next ot the ECT2 and is 12V ignition switched power.

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:

When you say you used the white wire on the MAF/IAT2 harness u mean you spliced into it? Not sure how to connect it. I just used an open fuse alot in the underhood fuse box, but I'm not very confident since it's constantly on.

That is an awesome pic of the wiring diagram. Thank you! But you might also know, is there a plug that i can use to connect to ECT 2 so that i don't have to splice into that connector? what is that part number and do you have a link?

Is there any shop out there or mobile mechanic that can install this flex fuel system for me?
I live near Santa Monica, CA. I already have the Jailbroken ECU and Flash Pro.

The plug exists, but I'm not sure of the part number or which connector series it is. Hopefully Hondata or SiriMoto can chime in and give you a part number.

Anyone else get a P00087 Code? Low fuel pressure at the fuel sensor. I was at E41.9. I was WOT in 3rd gear and car just went straight to lymph mode.

What calibration? You need to lower the maximum air charge at that ethanol content percentage.

Flexfuel with mods. I thought the air charge would adjust automatically. I will look into it more when I get off work today.

 

[ctrmofo]

for those who asked, pin 3 (white wire) off the maf sensor connector is where you want to connect with something like a posi tap or another type of splice. it's the ignition/switched signal of the maf sensor.

see pic showing pin 3 of the 5 pins connector.

It will, but if you have modifications, especially a downpipe, the extra air flow will max out the stock fuel pump. If is pretty easy to reduce the air charge at 40% ethanol, so if you post your calibration here will we do it for you.

Wow, Hondata with the personal support!
Always cares about their customers.

Wait, so the 'fuel system power limit' I've seen mentioned in a few threads is due to the capacity of the fuel pump? For some reason, I thought it would be the injectors. They cut it rather close, didn't they? If one replaced the fuel pump with a higher output unit, anyone have any idea the power capacity of the stock injectors, etc.?

Thank you for your time.

There are no fuel pumps. If you look at direct injection engines that make more power than the K20C1 then they just put on two fuel pumps to get around this problem. eg Mercedes V12
