Spec sheet for the new Sprint RE. Should redefine the entry level rotary ECU IMO.

 

cost and impression...

 

Cost: is great. Problems: 16x16 map, high impedence injectors only, 2 outputs available

 

My impression of the Sprint 500 (general equivalent of the RE version) has been outstanding. Think of it as an E6X that is less expensive, uses the great ECU Manager software, and without the trigger issues the E6X is prone to have. I really don't feel the 16x16 mapping is a handicap at all, my opinion anyway.

The high impedance injector drivers aren't ideal for the traditional rotary build. That said, there are a ton of great high impedance injectors on the market now. If you already have low impedance injectors you can use resistors with them. It's not ideal but it certainly works. The 3rd option would be an external driver box, though if you're going to spend that kind of money you might as well pickup a Sport ECU.

You are limited to two programmable outputs, in addition to the built-in Tach and Thermo Fan outputs. So you can still run an open loop boost controller and a shift light for example.

Other pluses:
4 ignition outputs, allowing direct-fire ignition on a 2-rotor.
Built-in 2.5 bar MAP
Direct USB connection
Laptop datalogging
Uses Data Manager software


Price? Haltech MAP is $746.94 with harness.

 

A bit of a nit, but are you able to specify injector dead times of the primary and secondary injectors separately? That appears to be one limitation with a standard Sport ECU - only a single injector dead time table.

 

Thanks Ludwing. That price is without Harness though.

I ended up just getting a P1000 today, should be more than what I need

Thanks

 

Correct. The price I quoted sounded pretty low. ECU and harness MAP is $866.25.

 

no omp control ?

 

Nope.

 

Hey guys,

Some info on the new Sprint RE. Mainly the diff between this and the Sprint 500 is that the 500 is piston only, the RE is rotary only. The specs on them are virtually the same, only diff is the trigger options.

Both Sprint units will ONLY be able to run high imp. injectors per output, Haltech will have available a balast resistor box that will be reasonably priced, on the other hand you can always use the OEM 2nd gen resistor box and just wire it up. FYI, Haltech is stocking 630 and 900 cc high imp. injectors.

Both units do have the CAN output to be able to connect them to the AIM or Racepak dashes.

Both units have the onboard 22psi map sensor, and are capable of handling up 7bar sensors, how ever, BOTH Sprint units ONLY have 16x16 adjustable resolution.

They are NOT E6X replacements, but more affordable units. Unlike the E6X, they cant run Stepper motors, and outputs are limited to:

- 2x generic duty outputs, configurable to anything that needs to be turned ON or OFF, and as simple duty cycle control.
- 1x dedicated thermofan output
- 1x dedicated tacho output

As far as inputs go:

- 1x dedicated speed sensor input
- 1x dedicated O2 sensor input (wideband and narrowband)
- 1x dedicated Aux. RPM Limiter

Thats it, its the same for both sprint units.

If you have a 20B, you will only be able to run it with the Sport 2000.

Another thing i could say about the Sprints is that they will most likely be more at home being used in parallel to the stock ECU, that way you can take control of the injection and fuel and leave the rest of the stuff to the stock ECU.

Finally, idle control on the sprint is a very simplified duty vs. temperature and rpm table. Same goes for boost control, there's only a simple generic rpm vs duty table to do boost control.

I hope ive cleared most of the questions that have been thrown around on this thread. If you have any doubts post them. Haltech is fully stocked on Sprint units, both 500 and RE editions.

Also, on a side note, they now have the newly released fully terminated harness option for 13B motors for use with the sport 1000, these harnesses are all done up to length, heat shrink wrapped with all necessary connectors on hand, there are 2 options for coils, either LS1's or M&W CDI ignition. Now these kits are ment to be sold as part of a whole kit that would include ECU+terminated harness+coils (or CDI). Contact your nearest Haltech dealer for availability and pricing.

If there are any other questions, please let us know!

 

What is the fuel injector resolution?

Also, I can't find the "full service manual" referenced by the Quick Start Guide. Any idea where it is hiding on the Haltech website?

It is "For Racing Use Only" but it doesn't work with racing fuel injectors?

 

16X16 map for injection and ignition. Download the software and play around with the re map.

You see "For Racing Use Only" on any non CARB approved parts. Pretty much any ecu will have that statement somewhere. As to the racing fuel injectors your assuming they are low impedance, there are plenty of new high flow high impedance injectors around now. Haltech will also have a resistor box on its way for the unit if you still desire low impedance injectors with the unit.

 

By fuel injector resolution I mean the minimum stepping avalible for the pulsewidth. For example:
Motec M400 - 0.002ms
Wolf V500 - 0.0035ms
Haltech E11 - 0.004ms
Haltech Platinum Sport - 0.0064ms
EMS Stinger 4 - 0.01ms

Sorry, but I'm a little older than most of the forum members and apparently I don't see very well anymore. Where does it say that on the high-end Haltech EMS spec sheets?
http://www.haltech.com/downloads/pla...ifications.pdf
http://www.haltech.com/downloads/pla...tions%20v2.pdf

I'm also not seeing that anywhere on the Motec M2R:

Nor on the Microtech LT8s:
http://www.microtechefi.com/pdf/Microtech%20LT8S.pdf

Not seeing it on the Electromotive TEC3r either:
http://www.electromotive-inc.com/products/tec3.html

Can't find it on the Wolf V500 either:
http://wolfems.com/files/Wolf_V500_S...1_Dec_2006.pdf

Link G4 maybe? Nope, not seeing it there.

Surely the PFC has it... nope, can't find that either.

EMS? don't see it.

How about AEM?

Oh look!: "Legal in California only for racing vehicles which may never be used upon a highway." Hmm, maybe you English majors on this forum can help me out, but I'm thinking that doesn't have the same meaning as "For Racing Use Only".

High-performance racing fuel injectors are usually low impedance. The high impedance injectors tend to have a slower response time, but they are cheaper to produce so that is why they are usually OEM on street cars. Resistors work great as a ghetto mod so you can use the wrong fuel injectors with your EMS, but unfortunately they really screw up the dead time as the voltage fluxuates.

So is this high impedance restriction a marketing scheme for Injector Dynamics or something?

 

Resolution is .004 mS.

Not sure why you're making any sort of deal out of the "racing only" statement. Does it really matter? If you're in the US, and you fit any one of the ECUs you linked, any aftermarket ECU for that matter, in a late model car, guess what; you've broken the law. Everyone one of them is "for offroad use only".

Some of the best injectors on the market today are low impedance and there is a great selection of volumes. It would be nice if Haltech had used high impedance drivers, but in the interest of keeping costs low, they didn't.

You might want to check out the latest in injector tech. The modern high impedance injector is a better injector than the old EV1 style injectors. The venerable Bosch 1600s are pretty pathetic in terms consistent performance compared to the newer high impedance injectors.

 

Thanks!

Hmm, so the cheapie Sprint RE has better resolution than the top of the line Platinum Sport 2000? That's rather strange.

If that is true, then aren't you and all of the other EMS dealers setting yourselves up for jail time and/or fines if you are selling EMS units and offering support to people who are using them on their street cars? Is Steve Kan going to court for ten million counts of the crime of tuning street cars? Somehow that doesn't seem likely to me.

Why is there no "racing only" statement on the high-end Haltech models that are touted as "original equipment in cars and motorcycles"?

I am making a big deal out of it because:
1) I have never seen that statement on any other EMS units throughout the last decade.
2) I think it is ironic because the only EMS units with that statement can't use peak-hold fuel injectors, lol.
3) I was hoping that Haltech gave you guys some type of technical reason for the statement, which I assumed was in place because of some type of capability that the cheapie EMS units lacked vs. the high-end units that do not carry the statement in their literature.

Also, I am not asking these questions just to bust your chops. I am trying to decide what to do with my NA 13B that needs a rebuild soon, and the idea of running an IDA throttle body and Alpha-N EMS crossed my mind. I will probably just stick with the stock ECU and intake and sell the car when the new 16X RX-7 hits the market, but it's nice to shop around for options.

Yes, apparently I need to get more up to date.

 

For racing use only should be on any ecu or other part(exhaust, turbo, intake) that potentially could change its emission compliance. Unless it has a CARB sticker on it its potentially illegal if you are caught with it. A lot of states don't care and don't do checks but potentially yes there is liability in all of it. Look at what the guys in Cali have to go through if they fail emissions. EPA could have everyone that does not modify their cars with EPA compliant and test parts by the cojones if they had the manpower and will to do so. I would think anyone that does not have that sticker potentially is liable. How about this send a message to some of those ecu manufacturers and ask them if they are EPA compliant for vehicles where they replace the original ecu? HELL NO....

 

Federal law, enacted in 1968, prohibits modification of any pollution control device, ECU included, on any vehicle. Are you really not aware of this? There are exceptions to this, but generally the only approved parts are provided by the original manufacturers as they are the only ones that can afford to submit those parts for emissions testing and certification. Call Motec headquarters and ask them if they'll stand behind the use of their product on a street car in federal court. They'll quickly tell you their products are intended for offroad use only.

The Platinum Sport document is a misprint. The software has a .004 mS resolution.

 

is it a big deal to use resisters on injectors to convert them from 4.5 ohms or less.

 

It's not ideal. The PFC guys have been doing this for a long time though with a decent degree of success. With resistors and a high impedance driver running a low impedance injector you end up with an injector that is lazy in response and not very linear in response at low on times. In my experience with the PFC and converting to an external driver box instead of using resistors, you get a better idle and actually lower the duty cycle of the injector at high loads.

IMO, if you need to use an ECU that won't run low impedance injectors, use a driver box. If you are starting from scratch and want to use the Sprint RE, use the latest high impedance injectors.

 

anybody run this setup.

 

Correction, for all of the E8/E11/Sport ECUs, the minimum adjustment (resolution value) is 0.002, the mini adjustment value using the keyboard inputs was 0.0064 on the E8/E11's and on ECU Manager its 0.004.

Hope that clears that up. What was that about motec and wolf? :P

 

Seems like a reasonable budget ECU... i may get one..

 

i live in CA, and USUALLY the owner of the car is responsible. the police officer gives a ticket. they do have pictures and lists of what to look for on popular cars like the SR20 s13/s14's and you go see the smog referee, and you get to turn it back to VISUALLY stock as well as out the tailpipe.

if they catch several cars that were all done by one shop, the brown shirts will stop by the shop and tell them to stop selling ECU's. i know of one rotary shop around here that got told not to put power FC's into FD's anymore.

this isn't really new to CA.... cops have been seeing the CARB sticker and looking for the carburator for 20 years....

 

Its amazing, and we're supposed to be living in the 21st century where a Haltech (or any EMS for that matter) would let the car run better than with any freakin carb.

 

'With a smug Face' Im glad i live in illinois No smog check for 95 and older cars
