No, only one wideband is necessary for O2 correction. There are wiring instructions available for this, it is pretty simple. Email / pm me if you need them.

 

not sure if anyone is interested but since i posted above i will let you know how I wired up my Haltech to turn on my oem fans. I wired this up to the low speed fans. I used AUX 2 from the H-PNP and tapped it into the relays for the fans in the IPDM. Set the threshold to 90 C instead of oem ~99 C. Below is where I tapped it into.

Now my fans come on earlier. YAY.



NOTE: The pinouts above are only for the older model ie: non-revup etc.

 

Hey, Hal, any updates on some of the features that have been asked for, or new versions of the soft/firmware?

Thanks
Dave

 

Active knock control?

 

Yes - shoot me an email (hal at injectedperformance dot com) and I'll get it over to you.

 

I do believe you can now just create a map with knock count along one axis and timing along the other for active knock control.

I haven't tried this yet. A screenshot of the UI demonstrating this would be cool (hint, hint) I won't get to play with this till May 10th. I'll try to set it up and see how it goes...

 

Will this ems work on the HR powered 350z?

 

I believe it can if you're creative enough with wiring up the harness . I'm sure the IP folks will chime in with some info on a vehicle specific harness shortly.

Check this website out - they are already working on a GTR version - and claim it will be up and running in a few weeks!!!

 

Hal,

I know you guys are working on integration with the stock CEL system for the Haltech. I like the proEFI's ability to throw a CEL to warn about certain conditions. Would it be possible to actually "label" cells in some way so if that condition occurs, it could trigger a specific CEL code. So rather than that cell outputing a signal or correction, it actually spit out a code?

That would be a very cool safety control/warning system! It's one of the most attractive announced features for the proEFI (IMO).

 

So I have also upgraded my UTEC to Haltech. I am expecting it from day to day. QUESTION. Can Haltech alter the max RPM limit of a 04~06 engine? According to manual this is not the case.

Also I can not find the active knock control anywhere in the new firm-soft ware

 

In the 05-06's, the rev limit is controlled by the throttle, rather than by fuel cut. As such, you will not be able to raise the rev limit, with Haltech, or FCON. In the future, I imagine that Haltech will allow for drive by wire control, and then you could certainly change the rev limit.

For now, the 05-06 guys will need to have their factory ECU rev limit reflashed.

 

Hal, Any chance active knock control is around the corner?

 

That is impressive, I am glad to hear they are on the ball for the GT-R.

I am assuming it would be plug and play of course

Maybe I will be getting a GT-R sooner than expected.....

 

The GT-R is on the dyno now - started right up with the Haltech Platinum on the first try. It should be at the track soon to test before/after tune.

Also, we are working on the HR plug+play harnesses now. Currently it is available as a wire-in unit.

Thanks great!!! Thanks for the update.

 

So I suppose that with my car the rev limit works fine. I have a 03 model. Thanks for the info.

 

Warning: this is a dumb question:

The new G8 has something where when cruising a few of the cylinders turn off to conserve fuel, could something like that be programed into the Haltech?

Certainly not a performance oriented idea but someone might consider useful. I don't care about gas milage because I never drive the Z but...

 

I mounted my Haltech to the plastic cover under the glove compartment in a G35 Coupe.



Should I run an external ground from the Haltech to the frame of my car? I remember some early UTECs have grounding issues, but I have not noticed any with my Haltech.

I thought I read somewhere that the Haltech was internally grounded through the cables. Does anyone know if this is accurate?

Thanks!

 

It may not be required but an extra ground can't hurt.
