I already searched and read the few threads about it the forum has to offer. My main question is, who is using them and can make an honest comparison? Thanks.

I've installed one Sprint RE and one Sprint 500. It all depends on what you're looking for. 16x16 is enough for most engines. With the Sport ECUs I don't think I've ever used the full 32x32. With a radical bridge port where VE changes very dramatically in a short range of revs being able to throw a bunch of load sites in a narrow range is nice, but most people that have radical bridge port engines are probably looking for a more full featured ECU anyway.

Basically, it does what is listed on the spec sheet very well. If you need more features, then you need to look at another ECU. The Sprint, when working within what it does, does those things just as well as the Sport ECUs.

 

Agreed, I rarely use ore than 16x16 unless I have to add a bunch like C. Ludwig said. You can still change them to whatever you like, so there is scope to close up some areas (like idle if need be, or dramatic VE change point as stated) and broaden out the boost areas if finer resolution isn't required. Done a Sprint 500 and another on the go right now, am yet to do a Sprint RE.

 

I am looking to get a Sprint RE soon after I sell my Rtek 2.1!

I have been playing with the ECU Manager and I am loving it. I am just undecided on a Sport 1000 or Sprint RE. My car is an S4.

 

its a 400 dollar difference, but its worth it in terms of customizable longevity to have the sport 1000.

ive been reading up on it some, and ive come to the conclusion that the sport 1000 is the better unit in a turbo charged application and the re is perfect for a non turbo application.

 

Why so?

The only disadvantages I can see are lack of oil metering pump control, and only open loop idle and open loop boost control (via General Purpose PWM out).
Idle control I can live with unless the engine has aircon in which case it would kill the engine unless you have a high idle to start with, and boost control doesn't affect us in NZ so much as our climate doesn't vary much (in elevation and temp etc), however elsewhere I can see that affecting it.

Depends on the application, I see Sprint RE as a suitable street car or club car unit where the owner never will use datalogging, even more so in old-school applications wher there isn't any aircon or extras.
Personally I hate having to add oil to fuel and its something else to carry in my car, so metering pump control is nice however...

Got carried away there hmmm, but anyway, I am curious why you came to the conclusion you did?

 

i have no idea. i just future upgrade ability to be paramount.

 

I do not have AC and I have a mechanical OMP. The only issue I have ran into is being that I have a narrowband TPS. Other than that the Sprint RE seems to be fulfilling my needs just fine.

 

I don't even use closed loop usually, and I tune for lean cruise open loop, so in that application a Sprint RE would be perfect in my opinion. As SirCygnus said though, future-proofing can be useful depending on the direction your car may take.

 

I'm with SirCygnus on this one.

 

regardless. think about it. on a turbo application, your going to have to use a boatload more inputs and outputs. water, intercooler spray, radiator fans.

for a NA application, the sprint re is literally spot on perfect. in a turbo charges application, you'll want more timing control and a way to accurately read your timing sensor.



do you want to have a "that'l do" attitude or a "we have implemented everything just in case you want it or a future user wants it. we over engineered it"

just think if mazda still made 12a's because they figured that was enough.

 

What?

 

some people think there is a better option than the stock crank angle sensor.

 

I'm one of them. The SRE can read the 12+1 and the Renesis trigger. Same as the Sport ECUs.

 

Ok this is what I have, HBP, t04e 60trim/1.15ar and looking to make 380/400 whp. And 400+ with water/meth injector. Is this standalone good enough for my goals.
ps
Can I setup 2step with this.
thanks

 

Yes, but only if you are running the usual in/outs, ie fuelpump, radiator fan etc. As stated above, if you start wanting to add things down the track you'll run out of inputs. It does have a dedicated secondary revlimit input (usually from clutch switch) so yes, 2step is there. No metering pump control. Is your meth injection standalone system?

From the question it sounds like you want to use it for drag racing? I personally would go for the Sport1000(or 2000), but not for any reasons stated above. I would get it for the onboard logging. Datalogging is amazing once you get used to looking through it, you'll be amazed how much you can learn about your engine or run/lap. The inputs and outputs it has may be an ice bonus though.
Sprint500 can log to laptop, however you'd need one with an SSD as normal Harddrives shut down from the G's on launch/vibration.

The guts of it is yes, it is more than good enough to run your engine but it depends what else you may want it to do.

 

Thanks, now with more thought, I think I'll get sport 2000 because of future plans. I'm still learning a lot, (rebuild/ported my engine last summer had a blast doing it) and now I'm learning about stand alone and everything that goes with it. I would like to get a 20b sometime in the future that's why I'm going with the sport 2000. I thought I would get something cheaper now to hold me off until I'm ready for the 20b and sell the RE ecu off and get the 2000 then. But if I get the 2000 now, I can learn and get use to the system and it would make the transition smoother once I'm ready and comfortable to get into a 20b.

 

Yeah, good choice in that case

 

well i know several racers that are running the sprint re and dont have any issues with it...its based off of what you are looking for but it will do what it need to do and you can run it in a race car
