Hi there,

I'm looking at purchasing a Haltech Platinum Pro plugin ECU for my R33 gtr and i'd like to obtain clarification whether the ECU will support the factory AFM's or totally rely on the MAP sensors. I vaguely recall reading that it can support both but i'd like to find out for certain.

In this respect, does the ECU operate or perform better under a particular setup e.g performance/economy wise? I realise this may trigger a wide debate but it would be good to obtain people's experiences and setups relating to this ECU.

Thanks,

Adrian

I think i may have found the answer to this from haltechs site

"Supports R32 GT-R twin MAF sensors" and " Selectable onboard internal MAP sensor rated to 150kPa (up to 1.5 Bar or 22psi boost)"

So i take it will support the twin afm's. Does anyone recommend the AFM approach over the MAP setup? Im generally looking at keeping the factory airbox thats why im keen on checking if its the preferred approach.

Thanks

An ECU is only as good as the person tuning it. Talk to your tuner and see what ECU/sensor setup they recommend.

The Platinum pro does support twin AFM's, it also has the option of an internal or external MAP sensor.

I have one in my R33 GTR, using the onboard MAP sensor, cold starts are great, idles perfectly, power wise its making 320kws on a run in tune, not sure on fuel economy as I've only put a few hundred kms on it since the run in.

Many thanks guys, this is exactly the type of information i was after. I should really get in contact with my tuner and Haltech direct.

Johno, you mention the internal MAP is working well in your setup. I'd be looking at a similar power figure (is that with the N1's?), but basically what i take from their site is the onboard unit would be efficient to 22psi. I think that is more than adequate on a standard internal engine. Obviously pushing more you would need to revert to the optional MAP sensor.

I think i also have read that the ECU supports two ignition/fuel maps, making it possible to switch between two tunes?

Cheers

No probs, Its working quite well. I will be swapping over to external map shortly and turning up the boost. That's correct 2.5 Bar internal is supported. Im running 2530's but N1's (GTSS or -7's) will get you into that power range with a bit more response.

Yep, you can load maps quite easily. I aim to have 2 maps done, one for street (98 octane & fuel economy lol) and one for E85 when its more consistent & readily available.

Cheers,

Johno

My thoughts exactly johno.

Switching between the two maps; is it as simple as loading up from the laptop? I doubt it would have some sort of an external switch that would allow this, though it would be ideal!

In regards to knock control, i couldn't see anywhere in the spec's whether the unit responds to knock by say reducing power or rev's?

Cheers for the responses they have been helpful :)

You wil have to load via laptop for now.

Live Dual Mapping - Not yet, but I have been told its only a firmware update or 2 away, probably about 2-3 months.

The Pro series does full knock control, long term and short term trimming. It also does long term and short term Fuel control.

It will flash the engine check light each time a knock even occurs and even log it if you like.

And without starting a new topic, are these plug and play into the rb25det series 2? They sound more functional than a power fc... Whats the price on one of these?

Auto tune mmmm. There is an auto tuner for power fc but I ain't have the gonads to try it out. All it needs to work is the wide band and some limits entered by the user. I think it should be an option, its nothing fancy really. Have the ecu know what car its on and let it load up some target afr's and start adjusting til they are met from the wideband feedback. After fueling, give timing until a threshold of knock is heard. Then the user can go over it to adjust anything if necessary.

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
