GT Motorsports: 370Z Supercharger system development

1slow370

Now just to be sporting here is my question about the MAF placement between the kits, How come no one is setting the MAF sensors in a draw through setup so they can actually measure the volume of air entering the engine before it is compressed, and splicing the IAT wiring off to a manifold sensor to accurately measure the incoming air temperature? I restate my question of whether or not you were able to upgrade the MAP sensor to gauge the amount of pressure in the manifold, or by retaining a mostly stock setup do you plan to simply adjust the fuel tables and VE to go around the problem.

Ok now sam answer my tech question

(oh and it's been almost three weeks now are my test-pipes still on back-order)

SAM@GTM

Let start with map sensor, the map sensor that you're seeing is a very low range map sensor or in a better way to describe, it is a barometric press sensor, It is mainly there for altitude compensation.

The key of placing the intake temp sensors as a blow through is to give the ecu the most accurate info possible so the intake temp compensation can be effective .

If you place the sensor in draw through setup, compensation for heat soak condition(for example) will be impossible and if you put it in the charge pipe (the stillen kit) then you are always reading the hot air out the blower .

Therefor placing the maf sensor in a blow through will gave us the most accurate reading of air temp before entering the engine.

I know it's a 1bar map thats why i asked if you upgraded it to like a 2bar, but i don't know if uprev supports the map scaling to do this.

What i ment is why not add 2 IAT sensors and splice the wiring from the combined charge sensors nissan gives you to them so that you could have a more accurate draw through MAF as well as charge temp compensation from the IAT's

Edit: I'm fairly competent with EFI and F/I as i've done NA conversions before so i know what the sensors do

Edit2: I'm wondering how you accounted for the increased density since a blow through MAF cannot pick up pressure and the factory sensor can't either

SAM@GTM

And why would want to tune via Map and not Maf, This is like going backward

Sam,

Please keep your comments in regards to our supercharger kit to the facts...Your information about our kit is inaccurate.

Best of luck!

SAM@GTM

Thank you for your support Kyle, and the best of luck to you too

PLEASE READ below...shady-ness alert!!

Sam's original reply, in case no one noticed clearly (unless Sam has changed it back, as he should do):

Kyle:

"Sam,

Please keep your comments in regards to our supercharger kit to the facts...Your information about our kit is accurate.

Best of luck!"

Sam:

"Thank you for your support Kyle, and the best of luck to you too

Sam"

SAM CHANGED THE WORD "inaccurate" TO "accurate" BEFORE REPOSTING THE QUOTE AND HIS REPLY!!!

Very shady, Sam. As others have mentioned here, your professionalism is severely lacking. Not good when you're about to charge thousands of dollars per kit and you know you'll be required to provide excellent customer service.

Please focus on repping your own kit and leave it at that. Thanks.

I have been looking into GTM products with great admiration over the past few months, with them being on the top of my list for future FI for my 370z.

After coming on this thread tonight and witnessing the past few pages of this thread, all I can say is that GTM has been moved to the bottom of my list.

I expect a much higher maturity level coming from a vendor here. Vendors are here to put out their products for us to buy, the general public is here to make assumptions, flame, put down other products, praise, review, etc.

Stillen, whether your s/c turns out to be crap, or a good unit, I thank you and respect you for keeping yourself composed and professional while all this flame posting has been going on. GTM....you have a lot to make up for and your s/c kit better be a gift from god of the FI market.

STILLEN: 0
GTM: -1


P.S. Sam I believe you need to talk to Tony over at F.I. to give you some PR tips

His comment seems pretty accurate to me. I like both systems but there are things in both systems that I do not like.... I will not pass judgement until I see dyno results on both systems. Sam's statement is correct according to a Nissan master tech that lives next door to me, that is also heavy into modding the Z platform since the Z32.....
