- One of the new products released here at SEMA 2022 is Haltech's brand new R3 ECU.
Now this follows on from the R5 that was released a little while ago which is a larger ECU.
The R3 Anthony, let's talk about what it is and what it isn't and let's start with the
number of cylinders it's really designed to drive here, what sort of engine would you
choose the R3 for?
- Yes Andre so the R3 is actually suited for up to 8 cylinder so this would be great for
LS guys and even our JZ guys, our RB guys, remember it's up to 8 cylinders, so this
could be used on a K24 with staged injection or 4G63 with staged injection, there's still
8 injectors at play here.
- So you've got 8 injector and 8 ignition drives, so you can run that 8 cylinder engine direct
fire and sequential injection.
- Yes sir, yes sir, that's the point yep.
- OK in terms of the big difference with the R5 when that was released is that it's the only
ECU at least that I'm aware of that incorporates a power distribution module, power distribution
unit, whatever you want to call it, as well as the ECU all in the one package.
You've carried this on with the R3, it's a little bit tamed down so what have we got there?
- Yes so you're completely right, the R3 is turned down as far as the amount of output
control which we just covered but as well as on the PDM side, we're able to retain the
four 25 amp outputs and that's going to control your fuel pumps, your cooling fans, you could
do starter control as well.
But what we really lose here are the 8 amp outputs that the R5 had.
So the R3 still has the dual H bridge, or sorry double H bridge, so we actually have four 8 amp
outputs if the H bridges are not being used.
But in cars that are going to be single drive by wire throttle body, they'll use at least two
of the H bridges, leaving two available 8 amp outputs.
- Alright so just to clarify there, you've got the 4 dedicated 25 amp outputs, so really this can
be a hub for complete control power wise of the engine, it's not going to control your whole
car but then that's where it gets a little bit of a grey area, you've got the 8 half
bridge outputs and if you're not using those for engine functions such as as you mentioned
there, drive by wire throttle which would use up two of them, you can use any unused
and function them as a normal power supply output, up to 8 amps correct?
- Correct, you got it yep.
- OK just wanted to clarify that.
- Alright other elements of this particular ECU, how about wideband control?
- Yeah so that's a really big thing because every customer in the past always had to buy a
wideband controller after the fact, when they purchased their ECU.
So with the R3, just like how the R5 had, it had dual wideband input.
So with the R3 we have a single wideband input which will still allow the customer, if they have a
V bank engine to purchase a secondary wideband just as they would with the module in the past.
- To be clear, this is onboard, you wire the sensor to the ECU, this isn't needing an external
CAN based controller, correct?
- Yes correct yeah, the one onboard wideband sensor available for the R3, you would just wire
the 6 pin O2 sensor to the ECU itself.
- OK in terms of logging capabilities, what's the R3 got available there?
- The R3 has 128 megabyte onboard data logging memory.
It is slimmed down from the 512 megabyte data on the R5 so we did have to trim some of that down.
- Alright this is a new product that you are just debuting here at SEMA, is it available for public
launch yet or is there still a little bit of work to go before it's available to purchase?
- Still a little bit of work before it's available to purchase so we're hoping that it'd be
available quarter one of 2023 so just a couple more months.
- And if people do want to find out more about the product or get hold of a Haltech dealer to
purchase one when they are available, where are they best to do so?
- Please visit the website, haltech.com or please talk to your local dealer.
- Perfect, thanks for your time Anthony.
- Thank you Andre.
