Sprint Booster review for 370z 7 speed AT

WarmAndSCSI

A tune cannot solve the inherent delay with DBW. While datalogging on my Evo, I found there was always a delay between the ECU sending the signal to open the throttle plate, or at least acknowledging that it had sent the signal, and the throttle position sensor actually registering the change. A device like this that actually adaptively ramps the throttle opening rate based upon your initial "punch" is a good way to compensate for this lag.

I know people are saying a tune can accomplish the same thing, but it simply cannot without re-writing ECU code or compromising driveability. I've messed around with DBW throttle tables on the Evo X extensively - you really don't gain anything over the stock settings. In fact, it consistently makes the car drive worse if you mess with the throttle tables too much, especially on a quick-spooling turbocharged car.

That said, I'd need to play around with a Sprint Booster on my Evo to make any fair judgment. It may really not do anything more than playing around with the throttle tables - it depends on whether it's actually "intelligent" or adaptive in any way.

by continuously measuring and converting the digital signal and providing the ECM (Electronic Control Module) with a new and altered signal for much quicker response so there's gotta be something more than just a diod or what ever it is that gives the signal to the ecu to have a better response and less lag?

Well for one it isn't even a digital signal, it is an analog signal at that point. There is no intelligence to this device, it does not connect to CAN or OBDII or anything except the pedal control unit itself. It is simply built to boost all pedal output voltages in the mid range depending on the "mode". The only lag it reduces is the speed of your right foot.

What I suppose it may do is some form of fuzzy logic on the throttle input signal. It may "learn" based upon what it supposes you're trying to accomplish - be it a quick 0-60 sprint, free-revving the engine, or easy highway cruising trying to save some gas.

Some basic calculus on the past x seconds of throttle input voltage could tell this little device quite a bit.

Who knows?

From watching the videos and reading the descriptions I'm pretty certain that neither the SprintBooster or the Blitz have any intelligence. One video just shows a driver holding the throttle at a fixed position and then it progressively revs higher as he changes modes. This confirms that it is simply increasing voltage by a fixed percentage when the input is in a certain range.

I do have to congratulate Mini Mania on slick packaging and good marketing. Some people certainly like the feel of the more aggressively mapped pedal, and the fact that they are able to sell these at this price is impressive. I'm sure there will be a Taiwanese knockoff hitting the streets in a year or two for $99.

This one from Blitz has two auto-learning modes: Blitz - Throttle Controller Full Auto Pro - Nengun Performance

I'd be disappointed if it didn't do some kind of instantaneous analysis on the throttle input as well.

this porduct has been out for 2 years already so why the f..k i cant find knock off's? and it was awarded by Sema last year. kinda weird if its that simple i cant find cheap Korean models anyway before anybody can say what ever they should buy one and check it out. and Chris i like the fact that your so certain without having the actual product in hand nor even tested this thing lol

edit: ohh and i dont miss that delay btw im pretty happy with the fast throttle response

Im with ya on this one....how can anyone knock it unless they have tried it.

ChrisSlicks

My analysis is based purely off the information the manufacturer provides, video clips and knowledge of the vehicle electronics. Not saying it doesn't work to a point, if you like it that is all that matters.
