I would like to use an ls3 maf/intake on my ls2... the plug is different though. anyone done this before? is there a link to it somewhere?

 

It's a little more involved. The pig tail you can get from Zip Products a forum vender <----------

Then copy the Air Temp table from an LS3 and copy it into your tune and then adjust the MAF tables and WOT.... that's all. Oh yea, if you are going to do this yourself get HPTuners and send them an email and get the beta2 version so you have access to the air temp table.

Or have a tuner do it.

All you need is the connector, avail from your favorite supplier and move the wire/pins over. And then rescale the temp etc with your favorite tuner

MAF transfer code, not temp.

The code is completely different between the Delphi 85 MAF and the probe MAF sensor.

You forgot the MAF meter as well.

Our package includes everything including the MAF tables.

 

sweet!

 

I have the ls3/7 intake housing and maf already... just need the harness to make it "work"

also, I dont HPTuners or any way to tune it myself...

 

Pretty much what I said, The IAT (temp) as well as the MAF transfer functions need to be changed. Most dont even know they are different and some tuning packages done even have the ability to edit the temp transfer. He has a complete LS3 asm and only needs a bare connector to swap it over then his favorite tuner (ME) can edit the tune.

 

I hope I am not highjacking this thread but I have more questions than I can find answers for.

Is there a problem with the IAT. I read somewhere that the ls3 MAF does not have the air temp sensor built in, is this true?

Also are the LS3 and LS7 P/N the same does anyone happen to have the part number?

What benefit does this ultimately provide? I know the lager tube allows more air at any given MAF reading (Hz) but does the LS3 MAF also have a higher frequency range or does it just allow for the larger tube & more air at a given frequency?

Lastly have does the MAF frequency patch play in to all of this? I understood the patch to extend the frequency range of the tables... so does the LS3 style MAF frequency range line up with the MAF Frequency patch?

If any one can answer these questions I think we would have a good start at putting all the MAF upgrade data in one place. I have not seen any soup to nuts on this subject yet.

 

The LS3 sensor has the IAT built in and is very responsive. I have installed and tune a bunch of these are they are a lot better than the 85mm MAF. The MAF Sensor will read 4096 g/sec, as long as the ECM supports it. The upgrade is very simple and not much to it. Just need a adapter harness, sensor and a place to mount it. The 102 mm MAF Housings are a great option. I have tuned S/C Vettes with this installed and makes 850 rwhp. So, it is a great option.

 

Does anyone know what way the wires are swapped when using just the connector and not a harness adaptor?

 

I know this is an old thread, but I just installed my ls3 intake, maf sensor and adapter harness on my 06, I need a tune with the ls3 maf tables, can anyone help me out? Thanks

 

download an ls3 stock tune from the tuners web site. If you can't get one email me

 

From HPtuners? I don't have that software, I have a t100 diablo tuner, will the stock ls3 tune work on a ls2?

Thanks

I ran a Z06/LS3 maf on my car.

You get the connector and double the MAF tables as a starting point for the tune.

Any Colorado locals who want this done, I tune it for free.

 

No, it needs a real tune.

 

All pinouts are in my thread above.

 

no you can't use the tune, only the MAF table as a starting point.
The ls3 table would be a good start only if you have the same diameter tube as the ls3, but if you just pluged the sensor in to another pipe then it has no corelation. BTW I thought the LS2 swap out was the LS7 sensor (my memory is foggy here).

Also why did you switch out the sensor? are you runniing an SC. If so then the MAP needs to be swapped too. If you've just put a CAI on then this mod is a waste of time and money.

This tip might help too... I had alot of trouble getting the car to run well after I put my SC on. It kept going in to reduced power mode untill I set the max flow settings in the diagnostic tables.

Here are the LS3 Stock flow nummbers but like I said they are only good to a certain point. Spin's method of doubling the flow and tuning is a good tip to use:

I switched to a stock ls3 air box/ air bridge, what ever its called, I do not have a supercharger yet, I got these parts for less than $100, I heard the ls3 airbox an maf sensor were more efficient/better than the ls2 setup, eventually I may swap motor over to a ls3,

I'm not good with this ecu tuning/adjustments how can I put that maf table into my tune without hp tuners?

Thanks

 

After reading this, I now know why I wrote a check and had some tune it.....
