Haltech Platinum Pro

[adzR34]

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.

Cheers,

It does support AFM's but I'd be gutting the AFM's (Meshes and sensors) and using the MAP sensor on the ECU.

Last time I contacted Haltech they said the setup for MAF is in the software but not functional yet, This may have changed so ring them first.

Bloody good ECU anyway.

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

[TiTAN]

does it support dual live maps? so you can just switch without loading in another map? (toggle switch on the dash wired to an input)

[J'z-R33]

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.

sorry bout bumping an old thread

i have read that if u use the haltech wideband with the platinum pro there is a auto tuning option, is this hard to set up?

[SargeRX8]

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.

Yer they are direct plug in for all r32/ r33 and are on special direct from haltech untill xmas for $1795 usually $1995

Gtr260. Pm/txt me about the auto tune. It isn't what you think it is.
