Want to eliminate your MAF?
Well, in some respects its true, but the engine at operating temp, with pressurized air, is hot enough to evaporate the atomized water/meth/alky/mix very quickly..
Like I said, there are different schools of thought and there's no really wrong answer.. this is just how I chose to do it with my original electromechanical system, and the new Buschur/SMC setup nozzle will also go in the same location.

Alright sounds good but trying to stay a little on topic, I think I was the one that strayed.
But this still sounds like a killer deal. Is there a number for the place, I can't find one.

Now on to a important question:
When will TurboXS let us know about a MAF replacement!!!!!!
Jermaine where are you

They will have a PNP harness for the evo8 in a few weeks. Not sure if you want to wait for that. Without the harness you will have to do some splicing. If you going with speed density you will need the GM 3 bar MAP sensor and the tail. You can find all the info on what part numbers you need to order for the sensor in the UTEC manual.
I already have a MAP sensor installed. So no need there, plus I have an extra one from a GN motor, but I think that one is a 1 bar. Ill have to double check the numbers tomorrow.

Since I have the injector just inches from the IC I would probably be best off on the speed density mode, correct?

This was from the website and rasied yet another question.
Speed Density calculates engine airflow as follows. Consider a theoretical " 4 Liter" engine for the following explanation. The engine can be thought of as a pump that, at 100% efficiency, will move 4 liters of material from its inlet to its outlet every 2 revolutions or the crankshaft. At idle the efficiency is mainly controlled by the throttle blade and somewhat by the camshaft/valve timing. At heavier throttle the efficiency is mainly affected by the camshaft and valve timing and mechanical efficiencies of its construction. The material that is being moved by this pump is air of varying pressure and temperature. Since we can measure the pressure and temperature of the air entering this engine, we can calculate the air being pumped through if we know the efficiency. This efficiency is known as the "Volumetric Efficiency" and is the main tuning element of the Translator Pro's Speed Density algorithm. The Translator Pro then uses the calculated airflow number to generate an airflow signal to send to the ECM/ECU. The ECM/ECM is unaware that the air measurement is coming from the Translator Pro instead of the original measurement device, and will deliver fuel based on the new airflow signal.
The very last sentence is what I have a question about and that is that with this unit it will make a calculation and give it an output signal that is close or as equal to the original signal that was generated by the stock MAF sensor. Now if the unit can do this mapping fuel through the UTEC will still be the same, as in it will be a Hz signal to the UTEC which will be passed to the ECU, right?
Sorry if it doesn't make sense getting kind of tired.

They have a messageboard on the www.maftpro.com site. Someone had asked a question similar to that. The explaination given was basically that you can keep running the stock MAF while running Speed Density. You can then monitor the output from Speed Density and see if the conversion is being done correctly. You can make adjustments until you have it right. Like I had said if this things works as they say, this will be an amazing product. If they market this correctly they will have a gold mine on their hands. It can even be made to control timing buy adding a "chip" to the unit. Currently I think they have timing control on buicks and DSM's. Personally I love the features that UTEC provides so I will not be removing it, but UTEC+MAFTpro is going to make a killer combo. In a few weeks we finally know if an affordable solution to our restrictive MAF has been found.
I should get the unit some sometime next week.

OK guys here I am. A couple simple things to go speed density you will need a MAFT Pro, A 3 bar map sensor (AEM 5 bar will work too), a GM air temp sensor close to the TB or in the intake. A harness to connect it. You can hook this up and the stock ECU or Utec will not even know the stock Sensor is gone. There is a full VE table for fuel tuning, there are controls on the front panel for tuning. It can operate as a boost controller, (using the map sensor to keep it where you want it) and if you have a wide band unit (we recommend the Innovate LC-1 but most others will work) you can enable the "AFR tracking" option. This will allow you to set a target A/F ratio for wide open throttle operation. The Pro will then correct the A/F ration when going down the track and hold it at whatever you set it at. This is great for N2O or Alky where sudden changes in A/F are common. On one of our Buicks you can see a 20% reduction in injector PW when the alky turns on very clearly in the datalogs (Pro does that too) but the A/F is constant. We are looking at timing on the EVO but do not have a firm answer there yet. I will be happy to answer questions but am not a sponsor here (yet) so I don't want to step on toes. Buscher Racing and Extreme PSI are both dealers. We plan on going to Dave's for a little tune session on one very soon. The EVO software should be done next week and it will be officially supported by us and shipped at that point.

Mike,
Any chance of a watered down (cheaper version) which just gives us UTEC users what we really want. A Blow Through MAF or Speed Density with no other features that we already have.

Ahh I can sleep better at night now. I know when searching through the site they offered all of these things that you will need, wondering on a package deal price.
