Well its here! we're in the beta stages of the new ECU Manager 1.08 software and Renesis trigger support has been finally added to the mix! The Sprint RE has been successfully installed in the renesis as well and is running very well already!

The Sport ECUs allow for far more control over the whole engine operation under all conditions. Control of the different solenoids for the auxiliary intake port butterfiles, AND preliminary tests have also been done controlling the Auxiliary Ports on the engine!

I already have diagrams available for the installation in parallel with the stock ECU, and the guys at Mazdatrix have been controlling their RX-8 race car with a Sprint RE unit. They were experiencing some issues, but it was all corrected and the car runs great now.

The Sport 1000 and 2000 will now be able to give the user a full stand alone ECU to take full control over the engine's parameters.

Here's a little preview just to wet the lips. Expect full product release within the next couple of weeks!

 

What other changes does 1.08 have?

 

So the Sport ECU's now control the 3 stage injectors as well smoothly? Are you able to idle the RX-8 at 15 AFR like the stock computer with all the idle controls? This is very good news. I hate how you have to rely on the stock MAF with the CobbPort. Looking forward to progress with this.

What. RX8's idle at 15:1!? I doubt it, or they wouldn't have an air pump...?

 

They're air pump only comes when you start the car to warm up the cat for a minute or so. It never works again after that. Since with the side port exhaust, you no longer have overlap, there is no need to idle rich anymore like with all the older rotaries. The car idles at 15.0-15.1 AFR and tries extremely hard to cruise at exactly 14.7 AFR even with minor throttle movements. By running at 14.7, there is no need for an air pump since its plenty hot. After about 3.8k RPM, it switches to 13.8 AFR during cruise to prolong cat life and WOT is in the 11's once the valves open up.

heh, learn something every day. Nice. As you can tell I haven't tuned one yet

 

Besides the fact that now we'll have the RX-8's trigger among the choices, there are other updates to the engine protection strategies, antilag and launch control have been improved, expanded some calibration and tuning tables, added a few more trigger patterns (mainly for other piston motors), fixed a few issues with triggering in specific applications, added more input options, etc., etc.

The Haltech pairs up 2 of the stages together, either the primary or the secondary, so you would have 2 stages, like the previous generation rotary engines. There is a way to have 3 stages, but we have not yet tested it to find out if there really are benefits.

I am confident that the motor can run just like stock with the Haltech ECU as long as it is programmed right.

Might also want to check out the thread we've got going on RX-8 Club Forum as well.

Thanks! And keep the feedback coming!

 

Could the 3 stage injection not be programmed in? The Haltech should be capable of doing it since you can control so many other outputs trigger by certain events or is it hardware limited somehow?

Also, is the OMP still controlled by the stock ECU? Is there no foreseeable way to remove and replace the stock PCM with only the Haltech?

the 09+ rx8's revert back to 4 injectors, so while nice, the 3 stage thing isn't a big deal

 

What are the injector sizes on the 09's?

thewird

 

As i answered in the RX-8 club thread, yes, the OMP can be controlled via the Haltech, thats not a problem, the problem would be all the other modules and control boxes in the car, not having the stock ECU would render most of them non-functional, the dash also wouldnt work. So unless you're turning it into a race car, then the stock ECU needs to be retained.

 

So the 09's and up use only 4 injectors, even on the high-power version? Do we know the sizes?

 

We only get the high power version in the US for series 2.

Primaries = 400cc
Secondaries = 525cc

 

I know the ECU connectors on the S2 will be very different than the S1, so if anybody has the pinout, connector diagrams and or pics of the ECU connectors as well, i would love to get my hands on it in order to see the main differences between the two and get the S2 going as well.

Thanks for the feedback, keep it coming!

 

I'll try sending you a copy of service highlights through your hotmail address. I dont think it has connector diagrams, but it does have pin numbers. Hope you get it.

Nevermind didnt work. PM me your email address. File may be too big too.
