Hey guys, I just got the new Blitz Throttle Controller installed on my 05 non-Rev Up Z.

It was very simple to install; you literally unplug the stock sensor under the dash in the footwell, plug the Blitz harness into the sensor and plug, and mount the black box & head unit somewhere and you are done, no splicing, etc.

The system has 4 modes: Econo, SP1, SP2, & SP3. Econo feels like a normal car, no more 'lag' in the throttle.

I prefer SP1 for normal driving -- SP2 is a little bit rougher, and SP3 can kick the rear end out relentlessly in all conditions.

The car feels alot quicker through being more responsive, this system obviously does not add any power, but it makes the car alot more fun to drive and alot easier to launch. I'm taking it drifting on Wednesday, I'll post some more impressions then.

 

$300?! Honestly? Basic reflash is $400 and would have given you at minimum what that does plus some actual semi tuned maps to go along with it. For $700 you could have had that, a full tune, and data logging/diagnostic tools. The things kids do these days.

 

not to mention that that thing doesnt really do anything for you. woohoo, i dont have to press the throttle all the way down to get mad response...or you could save $300 and learn how to negotiate the stock pedal...

 

Ok, so I should have bought Rich's reflash... and the throttle controller doesn't do anything; I feel so informed now

At any rate, if anyone has any questions about this new product for the 350z, fire away.

 

lol. It's really not the same thing. It will give you an instant increase in the throttle response curve at the touch of a button. I've you've ever been in an M3 or M5, you know what I am talking about. It really does help out on the track as well.

Uprev is good, but you would need to bring your laptop everytime you want to change the curves. This product isn't for everyone obviously.

 

Not true, it manipulates how the ECU sees you pressing the throttle. This product does not change the way the throttle plate itself reacts. If you want to actually gain full throttle at the throttle plate off the line, the only way is through changing the mapping in the ECU itself.

You bought an over priced variable reostat that has variable pitches, brilliant.

Just because it comes from blitz and it's mad phat JDM yo, doesn't mean it does much in the way of reality. If you'd like, pop on our Cipher cable and actually watch the throttle curves yourself, it's real time and it's what is really happening.

 

I know there was another thread on here about the bee-r one that essentially does the same thing...and a few members were very curious on the results.

 

Even if it does actually make the throttle move differently, it's not making the ECU do anything differently. It's yet another device that goofs with things fooling the ECU into doing something it's not prepared for. This time it's $300 and not $30 from ebay, that doesn't make it any more legit.

 

it really helps with people that want to feel like theyre at 40% throttle and get the kick of 60%. it has the same sweep (0-100%) of a stock setup, just changes your perception. could have spent 300 actually making the car faster instead of 300 to get the same power

 

^^hmm this seems kinda interesting, it seems as if that might be kinda fun.... I have osiris and cipher, would there be any way i can play with the throttle response to make it feel extra peppy they way this part makes it feel in the sp3 mode? If so id like to try it out....

 

Well this is suppose to remove the throttle lag you feel when you floor it. Other than this and SprintBooster(all the BMW people are talking about how good it is and their is now a model it for our cars), what other products would actually remove the throttle lag. Will a reflash or uprev and its software do it? I want to get something that will remove the throttle lag and what to look at all my options.

 

It's not throttle lag. Drive by wire systems will open at an optimum rate. Mashing the peddle doesn't make the motor rev as quickly as a throttle that opens at the same rate that fuel and spark raise.

These things are gimmicks, no better than the air intake temp sensor box. Yes they will make the throttle open more than where your peddle actually sits, but they don't make any more power. Does it matter that you reach 100% throttle when your peddle is only down 75%?

You need to do something to the ECU to change the way the throttle opens and if it gets WOT at low RPMs. Forcing the plate open to 100% at low RPM with something like these devices doesn't change the fuel or spark down low, so the ECU freaks out and does weird things. You have to adjust the parameters in the ECU to take advantage of it.

You're better off just slapping a bunch of neon lights and stickers to your car.

 

I hear what you are saying but at the same time, fuel/spark are referenced in part off tps, not off the gas pedal. So as the plate opens, the ecu reading off the tables it should be relative to the tps it is seeing. Hiding the air temp sensor is different altogether, as you are now feeding the ecu a false signal. My understanding is that this is not altering the tps feedback to the ecu in any way, it is strictly manipulating the ratio of gas pedal to tps movement, which really is a different thing.

 

Yeah, because that would be so helpful. The Cipher does a lot of stuff, but 95% of it is pointless for most of us.

If you want to sell more of your products, then I would suggest not coming into threads belittling people that bought something other than your product. Yes, the Osiris can change the throttle so that it can open 100%, but it doesn't do what this product does - regardless of whether you think the product is pointless.

 

It cannot manipulate the ratio of gas pedal to tps movement. All it can do because it is outside of the ECU is to send false pedal signals to the ECU.

So how is it any different than the fake AIT sensor box?

Any customer could replicate exactly what this device does for $0.00 by pushing on the throttle pedal differently. Thats is 100% all this device does is amplify and reduce the signal to the ECU from the throttle pedal.

Snake oil at it's finest.

 

Please explain what this product does then. Osiris can manipulate the throttle to act like it's open 100% when it's only at 1%, so that it scales quicker, but then what is the gain? 100% throttle is 100% throttle, if you reach 100% by the time you're only at 70%, you still have a maximum of 100% throttle. This device doesn't add power, if anything it reduces your control because of the scaling it does.

I wasn't comparing Cipher to this item, Cipher would be a reference tool that would show you what this product is doing, which is simply amplifying the throttle pedal signal.

 

Right, the Osiris can do it, but I assume it doesn't allow you to switch between different modes on the fly. Maybe this unit changes the throttle response curve as well, instead of just linearly. Plus - if this feature is so pointless, why even include it in Osiris?

I'm not trying to knock your product at all. I think it's quite amazing what all you put in there - especially for being a small company focused only on Nissan. All I'm trying to say is to each his own.

 

Map switching allows changes without restarting the car, and those are actual tunes that change the way the car drives for $400 (mail in ecu flash).

We don't include throttle pedal goofiness in Osiris when you order a tune, it's there though if the customer feels the need to have it for any reason. It could be useful if you decide to swap a VQ into a Subaru and want to retain the use of the factory Subaru pedals, so you'd need to rescale the throttle controls?!? So yes it is part of our capability.

I agree to each their own is correct, but to misrepresent a product is not ok, especially when people turn to sites like this to get their info and educate themselves before they purchase.

 

There was a white paper on the other product - where did that thread go? It is only a pedal signal amplifier as noted above.

If this product is the same, then it is more about "feel" than anything else and your $$$ are much better spent on Osiris for sure.

UpRev is doing the community a service by dispelling myths. Believe it, or not!

 

UpRev,

Is there anyway to actually increase the speed at which the throttle opens, what I am looking for is something that won't rescale the pedal, but actually improve the time, basically so it feels more like a cable-throttle car.

Thanks,
