I did some searching and could'nt really find anything concrete about the exact difference's between these units (Sprint RE and P1000). I started this thread to take it down to basics. I need to buy one of these and as far as I'm concerned, I don't feel the need to fork out that much extra for a P1000. I'm not concerned which one is better. I'm concerned about what one unit actually does compared to the other one. So what are the differences?

 

Platinum Sport 1000 | Haltech - Engine Management Systems

Platinum Sprint RE | Haltech - Engine Management Systems

basically they are the same except the sprint RE has fewer outputs, and smaller tables and a couple less options in the software.

 

On a basic level, is there any benefit to the mapping tables being larger? Does the sprint re have open and closed loop o2 control? Can the RE run a BAC valve for idle control?

I'm looking for something basic. I don't have a fancy or lucritive setup on my car.

 

This is something I wrote up a while back to help answer this question. It comes up a lot.

There are basically two popular options for the 2-rotor cars, either the Sprint RE or the Sport 1000. Both use the same ECU Manager software and Data Manager data logging software. The difference mostly comes down to the inputs and outputs each has available. The Sport 2000 can also be used, but the only advantage it has over the 1000 is more auxiliary inputs and outputs.

The Sprint RE has 4 outputs. Two dedicated (cooling fan relay and tachometer driver) and two user programmable (open loop boost control, water injection, shift light, etc.). The Sprint RE has three dedicated inputs, one for wheelspeed, one for 2-step rev-limit activation, the other for narrow or wideband O2. The Sprint RE uses a 16x16 mapping matrix. The Sprint ECU will do closed-loop fuel control when a narrow or wideband sensor is employed.

The Sport 1000 has more inputs and outputs (7 outputs, 4 analog inputs, 4 digital inputs, 1 dedicated 02 input, all user programmable). The Sport 1000 uses a 32x32 mapping matrix and has the advantage of being able to do closed-loop idle and boost control. The Sport ECUs can also do individual cylinder trim for fuel and spark and closed loop fuel control when used with a narrow or wideband sensor.

All Haltech ECUs have built-in 2.5 bar MAP sensors. This will support up to 22psi of boost pressure, saving the expense of an external sensor if you intend to run no more than 22psi boost. The internal sensor will work well for normally aspirated engines as well as forced induction engines. We recommend the use of the Haltech coolant temp and intake air temp sensors. The S4 TPS is not the best option for use with the Haltech system and we generally advise S4 owners to swap their throttle body and TPS for an S5 unit for the easiest and most reliable TPS. There are other options that use the S4 TB and TPS, but require some fabrication. Aftermarket throttle bodies generally include a full range 0-5V TPS. We may be able to supply the proper TPS for alternate throttle bodies but cannot guarantee fitment. It's best to ask first, rather than build yourself into a corner. The S5, FD, and RE/20B TPS work well with the Haltech systems.

It basically breaks down to this; if you just want to run the engine and not do much else, the Sprint RE will work great. If you want to expand on the auxiliary functions of the ECU or want to be able to log inputs such as oil pressure, oil temp, fuel pressure, etc., then the Sport 1000 becomes more attractive. The Sport ECUs also have on-board data logging, while the Sprint RE can only datalog to a laptop that is connected to the ECU. Many circuit racers need the on-board capability of the Sport ECU.

Lastly, the Sport ECU will do a few things the Sprint will not. Advanced functions like closed-loop and/or gear based boost control, advanced idle control, fuel and/or ignition trim, etc. The Sport ECUs now have a great 3D flex fuel control strategy as well.

 

Does the sprint re have an idle control function to operate the BACV?

 

Not really. You can set it up to run open loop as a cold engine idle up feature. But it will not do true closed-loop idle like the Sport ECU will.

 

Okay. I don't think I really need the bac since I deleted all the ancillary functions (no p/s or a/c). It will be a pain in the mornings but once the car is warm it should be okay.
