I know I should just ignore this but I can't.

Mr. Cleveland - What factors do you consider when you determined that our kit "was not even in the top units out there for the S197"?

Does anyone else offer a unit that flows more air?
Does anyone else offer Nitrous bungs that give you the ability to plumb your kit or run water/methanol injection?
Does anyone else offer calibrated electronics as an option?
Does anyone else have a polished one-piece housing?

If any of these are factors when determining quality I am sure most will agree we rank in the top 3. In fact everyone that has purchased our part has praised it
- it has a certain amount of

 

Ok JR, At least now I have a much better understanding how your able to calibrate the MAF electronics.. However, let's just say that for ie if the factory MAF sensor were able to read larger volumes of air in the same way before changing over to the current slot in style MAF electronics, which didn't require a PCM re-flash or any type of electronic corrections that permitted running a cold air intake by itself..So my question is this, are the recalibrated electronics designed for the sole purpose of correcting the sensitivty issues of the stock electronics only ?? Or does part of the re-tuning for your re-calibrated electronics also include modifying parameters, such as advance timing and spark..? Similar to what a flash tuner does..

 

You lost me. The reason why the old design MAF housing


did not require a reflash was because the electronics were calibrated to the housing itself. (like above) That means no matter what you put in front of it or after it - it always samples the proper amount air. However if you were to unscrew the electronic out of the style shown above and screw that it a different diameter tube you would have all the same problems. Granatelli addressed this by introducing the 80064919-0 meter pictured below


Here you see the it looks like the old design but now it has the proper plug in for the slot it style meter. You chose to use this design then again you could put anything you want in front of it and after it just as long as the air all funneled through the housing as it relates to the electronics as delivered by us.

Also the electronics we include in our kits actually have more dynamic range then a stock GT because we start out with the GT (as in GT40) slot in which goes 0 to 2000 kg/hr at 5 volts as where the Mustang GT is only 0 to 1650 kg/hr at 5 volts.

This math follows the same logic as the BA2400 and BA2800 we make for SCT. No one has questioned their repeatability because they are spot on. These parts are no different.

Hope that helped

this way (above) you get to make you own home made intake and it is always calibrated - or -

this way (above) we do it all for you

 

Sorry for losing you earlier, JR...I wasn't able to finish posting everything, I wanted to say, before being prompted to log back in..So I'll re-phrase, what I meant to say.. Let's say for ie, if the factory MAF sensor, were able to read the same amount of airflow, as you're re-calibrated electronics ?, and if there was no reason to correct, the sensitivty issue of the stock MAF sensor..Would you not be able to run a cold air intake by itself, much in the same way, before Ford upgraded to the new slot in MAF design ?? In other words, if the stock MAF sensor were calibrated to the MAF housing, what would be the difference, between you're re-calibrated electronics and running the very same cold air intake, by itself, that didn't require any corrections ?? would the airflow and performance advantages be the same ? or would there still be a difference ?? I hope, that I'm not losing you again, but I just can't seem, to put it, any other way to make, what I'm trying to say, any clearer...However, I have one last question, that I still don't understand..If the stock MAF sensor, is no longer calibrated to the MAF housing..Then what is the stock sensor, calibrated to ?.. Is it calibrated, to the computer itself, or what ?? And finally, what are your re-calibrated electronics, calibrated to ? Are they also calibrated to the MAF housing ? or directly, to the computer ?? Anyway, if it seems like, I'm repeating myself..I do apologize, but this is so confusing and difficult, to grasp and comprehend.. Which is why, I've been asking so many questions, to begin with..So, once again, thanks for be patient and taking the time, to explain everything... Also, when you get a chance..I edited my earlier post, so I hope you'll take another look, at the revised version, as well...

 

Thats a pretty sharp looking intake. Could a tune still be used with this setup via someone like Bamachips for premium fuel?

 

You just quoted what I said in the earlier post – you are correct. If the factory had a calibrated sensor mated to the housing then it should be able to adjust for any cold air intake. – Now you need to make sue the housing can move enough air



Well you kinda lost me on this one. Our electronics are calibrated specifically to our intake tube. Each meter is installed in the house and then flowed as a complete unit

 

Yes - just purchase part number 410040-1 or 410040-P1 for polished

 

You mentioned in the earlier post that before Ford changed to the current slot in MAF design, the reason why the old design MAF housing did not require a reflash was because the electronics were calibrated to the housing itself..So my question was, what is the current factory MAF slot in design sensor mated or calibrated to ?? Anyway, hope your able to understand where I'm comming from now..

 

Ya - now that is a simple question. The MAF is calibrated to the stock intake tube and the balance of the work (most of the work) is done in the ECM tune. This way Ford can use the same slot in meter for like 15 different applications. Each application has a differnt ECU calibration.

So I see where you are going with this. And my point still holds true. GMS/Hitachi can scale any meter to any tube as long as we can see the before and after application on our flow bench

 

Now you've lost me ?? I don't quite follow what you mean by and the balance of the work (most of the work) is done in the ECM tune..Or did you mean PCM tune ?? Nor do I understand what you mean by each application having a different ECU calibration.. in fact I don't even know what an ECU calibration is ?? How does this compare with the old style electronics which were calibrated to the housing itself ?? In other words was the balance (most of the work) also done by the stock tune as well ?? and also did the old style electronics have different applications that also had a different ECU calibration ?? or does the old style and new slot in design electronics work completely in different principles ?? Perhaps you can explain all this in easier and less complicated terms so that I can fully understand, where your coming from..

 

ECU - electronic control unit
PCM - Power control module
ECM - electronic control Module

It is all the same - just different verbiage

Bottom line...GMS can scale and calibrate any MAF sensor to any orifice

 

I am going on a road trip to meet customers for 2 days so I will be back on Friday

 

I could go for a road trip...hell, I could go for a coke slurpee.

 

Hell, just my brain could use a long drive after trying to figure out all of this complicated terminology language..

 

I back - just a warning

 

And I've been right here waiting lol..So If I'm understanding correctly, when you mentioned that your electronics are calibrated to your intake tube..I get the impression that your re-calibrated MAF sensor is in no way modifying nor changing the actual stock tuning files..? Am I correct so far about this ?? And if I'am.. Is it also true that your re-calibrated electronics also do not modify any of the stock's timing and spark curve parameters?? such as have the ability to either advance or take away spark and timing, if needed ?? and most of all..The ability of getting rid of that annoying throttle lag ?? And If I'm still right..Isn't it also true that only a hand held tuner, such as your Fuego flash tuner have the ability to actually modify the computer's stock tunning files ??? If were still on the same page, where I'm going with this is..Does not the combination of a cold air intake and flash tuner provide more overall performance and power gains than just your cold air intake alone ?? (even with re-calibrated electronics and no re-flash required) That's were I was going with this all along JR...So I hope you have an idea, where I'm coming from..

 

I'm no expert but here's what I gather from lot's of reading:

A cold air intake is in most cases a larger diameter Mass Air Flow(MAF) housing using the existing stock MA sensor which is calibrated for the stock MAF housing. Since the stock MA sensor in a larger diameter MAF housing does not send the correct values to the PCM then a tune is needed to compensate, else you run too lean. Most people don't recommend installing a CAI using the stock MA sensor *without* a tune.

Granatelli CAI on the other hand includes a larger diameter MAF housing *but* it also includes a new MA sensor that is calibrated to the new diameter MAF housing, therefore it sends the correct values to the PCM and no tune is needed to compensate. If this is entirely true then the engine should not run lean with the MAS calibrated for that diameter MAF.

But when you get a tune there are other tweaks that almost certainly mean that you will get more HP and Torque gains out of a CAI plus tune then you can from any CAI by itself (calibrated MAS or not).

So I would say the Granatelli unit is a lot better than a CAI by itself with no tune but not as good as a CAI with tune.

If you don't want to flash because of warranty issues, want a unit you can put back to stock real quick and don't worry about re-flashing to factory, and want to spend about $200 to $300 less than most packages (because most need the tuner) then this would probably be a good choice.

Now we just need to hear from some people that have actually installed and used one of these. <g>

 

Yes, I understand all that and had pretty much directed, the very same question to JR earlier, when I asked..Does not the combination of a cold air intake, and flash tuner, provide more overall performance and power gains, than just your cold air intake alone ?? (even with re-calibrated electronics, and no re-flash required)

 

I now say to myself - phooy! If nada is said from someone who HAS this unit installed - back to what is tried and tested. CAI/tune. Sorry, I'll be a gunnie pig on a lot of things, but not on something like this.
