Steve ..... we need to talk after the holidays

Send me your # in a PM.

steve

Check your previous PM's ..... you already have it

I'm not sure what catagory your putting my questions into but I'm still waiting for answers to my questions :hello:.

I see things with my GTM Stage 1 supercharger system that have me concerned. Between the cipher logs and the AFR, EGT, fuel pressure gauges I have questions that so far GTM wishes to dismiss and ignore on a regualr basis, in the forum. No PM's either.

Maybe there is something to my questions that GTM doesn't want the general public to have knowledge about?

^ mind sharing what the issues are?

+1 let us know

You are only adding to the any confusion in the community by vaguely alluding to a bunch of problems you are seeing. Perhaps if you made them public here then you could get answers, and at least educate the rest of us as to potential issues to watch for.

I don't think you will find a more forthcoming company on this forum with information than GTM. So I don't get your statement. Every dyno graph we post here has always shown all the info needed for the end user to get a full picture of how are system performs: Hp and torque and most importantly Air/Fuel ratio. You almost never see AFR on a dyno graph unless it is from us. Every car we tune always has knock equipment on it. Why? Because we dont take any chances. Especially when we are shipping kits out all over the world. So I don't understand what you are driving at here.

But here is the the biggest validation that our system works and that we have the best kit on the market. The car we posted here has the same fuel system you have and ran multiple 30 minute sessions on a track with no problems. Same fuel pump, same tuning method, only with more power due to the bigger supercharger. So why would this system work with this car, but not yours? Where's the magic at? Where's the secret? What's the difference?

As many have said here, the only way to advance the the community is by discussing it here, this way every one can learn from it.

Please don't take this the wrong way, Lloyd, I value your business, and I like you a lot and as always, I'm just a phone call away.

Sam

This guy is for real. Sam is all about helping people out and putting out a serious product. Not many can back their products like him. I spoke to him plenty of times and I don't even have one of his products (yet).

So I'm just gonna put this out there.........I'm not oneof the fanbois hanging on GTM, but I acknowledge that Sam and his crew are true professionals! :tup:

Firstly, I'm not the tuner and don't have the logs in front of me to answer all of your questions regarding IAT's and degrees of timing added. Ultimately, the proof is in the pudding: 40whp gained as a result.

Considering that MAF sensor cleaners generally consist of VOC's that don't leave residue and methanol is a VOC that doesn't leave residue, you will not be damaging the MAF sensor and you can bet that it'll be clean. That said, if you notice the size of the nozzle before the MAF sensor, the volume of water/methanol being injected before the MAF sensor is very small...just enough to lower IAT's that the MAF sensor is reading.

Because EGT sensors are very slow to respond to changes in actual exhaust gas temperature, they are not a very effective way to judge how the engine is running. That's old school tuning technology.

The modern method of checking engine operating parameters is through the use of a wideband oxygen sensor. That's what's important. If you are running lean, EGT is the least of your concerns. Another thing to recognize is that EGT is affected by ignition timing and AFR. As such, EGT does not give a clear picture of what is really going on.

In regards to your second post, clearly you have something else going on if you are talking about AFR and fuel pressure. What does that have to do with your other question about EGT's, IAT's and water/methanol injection? If you have a mechanical problem that needs to be fixed, and/or you need information relating specifically to such a problem, this isn't exactly the thread to do that in. As you can see, the answer to your question does not contain information to diagnose and/or solve your concern. Furthermore, I do not have any PM's or e-mails from you regarding your concerns. For you to imply that we have something to hide by not answering your question as it relates to the topic of this thread is confusing.

Fair enough, and that's all that had to be said. It would be nice to have some hard numbers to compare with, on what the 40 whp gain is with the meth injection versus without.

Yes it will be clean but from what I've read on meth injection, that it's a bad idea in have meth injection in front of the MAF sensors due to possible damage and the increase of the volume of gases the MAF reads, that could effect fuel injection rates. I'm sure tuning could compensate for that. The jet is very small and I'm sure at the end of the day, it will help more than hamper. That's why I asked for before and after IAT's temps, so that perhaps I should be considering designing them into my meth injection plan.

lol ...guess what, I am old school and EGT's will tell that something is not all right in the world and you need to look at other things. In my world a EGT of 1800F @ WOT is not acceptable and there is a problem(s) that need to be dealt with. The AFR on the dyno tune really showed where part of the problem is and what needs to be done. Yes we did call Sam, and unfortunately, they both missed it and I found the problem on the dyno. It's a small miracle and a testimate to Nissans computer programming that I didn't blow the motor.


I have had a few conversations with Sam on my issues and the basic answers I've received is that it's my fault and no one else has reported to have the same problem. So I feel I'm left to solve it on my own ...and I do. So when I ask questions on information given by GTM, shared with the masses, it would be nice to get the info, to help me solve my problem, and so when I get ignored and labeled; I get a little pissy.

So my apologies if you think I'm trying to slander/ discredit GTM in any way. I'm just trying to get enough info to help me solve my issue with my supercharger kit; plan my shopping list for the spring to resolve my issues and have a reliable supercharger kit that works as intended, if not better.

Trust me Sam, I value doing business with GTM as well. I like the engineering behind every GTM product and it was never my intent to bash GTM in any way. It is never my desire to publically share my issues.

Plus I plan to do more purchases this spring to correct my problems and make my supercharger system better and more balanced.

I just don't like being labeled and ignored when I ask questions on a GTM product released to the public.

Mike/Sam @ GTM - you guys done any e85 + Stage 2 builds to get around our poor gas here in California? I know we are very limited in number of stations handling it, but a person could have a fallback tune if they were in a pinch and needed to use 91.
