Hrf300 ecu with rrfpr

[1990timeismoney]

Hi very new to these ecu's ive just brought one and wondering if its ok to run it with a sard rrfpr and at what pressure. the car runs and fuels great at moment so if i plug it in will the fuel need to be adjusted.

Any help appreciated

Thanks

[daniel_g]

Is it the HRF P&P ECU or the HRF/Apexi PFC standalone ?

And always recommended to get the fueling checked and adjusted.

Will be fine to run with a FPR, always a good component to have to maximise your fuel setup.

Hi thanks for the replys its a hrf plug and play ecu I've got a wideband installed on the car so hopefully get it set up and running right

Thanks for the replys

[AdamB]

The plug and play's prefer stock fuel pressure so most people seem to say. Try it at 2.4 bar first and see how you get on. Most tend to run rich anyway so I doubt the fpr will need to be used

[Whitenoize]

As said above you don't really need the fpr just check the fueling with your wideband I don't have a wideband with my plug and play it's next on the list I just took mine to dyno to get checked And it does run rich as said above but it's safe being the main thing

Ok thanks i don't have the stock fuel regulator at the moment so ill turn it down to stock boost whats sort of power will these make with a td04 setup

[Whitenoize]

I'm not to sure about tdo4 tbh mate the plug and plays are more suited to ct9/hybrid but people

Do run them with tdo4 I'm sure you could still run more than standard boost

thanks

Bump any help appreciated

[triple j]

does the car start and run fine with it in,

[Amjad]

Didn't think it would have flagged up a light

[1990timeismoney]

It starts but runs lumpy and is going full rich

[Whitenoize]

Sounds like you have a mk1 gt hrf ecu the loom on a mk1 is slightly different so if your fitting it to a mk2 or mk3 ther is two wires you need to swap round

[Whitenoize]

The wires you need to swap are connector 2 pin 7 and 15 on a mk1 the boost control is pin 7 and on mk2 and 3 it's pin 15 the early hrf plug and play ecus are mk1 specific

[1990timeismoney]

Oh ok thanks is it worth cutting the wires and what exactly are the wires that need to be swapped.

Been a great help thanks very much

[Whitenoize]

I've got a PDF file that shows you all the wires on the ecu plugs think it's the boost control that need swapped i will try and post the link for you not sure if I can do it on my phone tho

[1990timeismoney]

Thanks very much link worked what wires need swapping can they be pulled out or do they need cutting

[Broony]

cut and solder leave enough length on to put it back if needed:)

[1990timeismoney]

Ok not really wanting to cut wires but looks like it will have to be.

Is there a harness available.

Still not sure which wires to swap

[1990timeismoney]

Any advice appreciated

[Whitenoize]

That's y I didn't get the hrf one mate didn't want to cut the wires I'd have fucked sumthing up me and electrics do mix well lol

Lol same here. trying to see if i can get a field harness and use that instead of cutting loom.

What two wires needing swapping.

Mite have to sell if can't get a harness for it

LukEp made a ep82 to ep91 (or vice versa) ecu plug converter loom, dunno if he'd be able to help you out at all?
