Well, I finally got a chance to install and tune a Haltech Platinum on my 350Z yesterday. Overall the unit works very well, installation is a breeze, and the VTC worked flawlessly.

The only changes to the car was the exhaust and EMS. Having the ability to control the VTC will make a huge difference when tuned correctly. Dyno number 103 was what my car was making at the last track rental/meet at Mason Dison, if you compare that to the current setup (run 153, same boost levels) it yielded me nearly 130ft/lbs of torque at 4400rpm. That's a difference that even your "seat of pants dyno" will pick up

Congrats to Injected Performance for offering the community another capable PNP EMS solution.

Awesome Ray !!!!

Did you tune this your self ?

 

But of course I honestly bought it just to see how well it worked, and well it works. Every tuner has their favorite EMS, I just wanted to check this one out first hand.

 

wow! i bet it feels great making more power with less boost

 

WOW! Thats some good numbers! Good tune!

 

You have a Revup? Impressive you picked up so much power up top peak over before. And I love the fact that your HP stays flat until 7500rpm's, that is a GREAT powerband for the track.

 

Nice tune no question - congrats. May I ask what EMS and exhaust you had before and which exhaust you switched to? I assume this is a Greddy TT? Can you provide any insights into your tune of intake vs. exhaust vtc?

 

Man!
Those Greddy turbos just have best power band.

 

Ray, congrats on the numbers and tune - I wasn't sure that you ever got around to installing it Thanks for posting up your findings, and let me know if you need anything.

RCDash / Alberto, I believe he is non-revup, and was using AEM previously.

 

wow...that powerband is absolutely disgusting.

 

Nice!!did you play with the VTC much to achieve those gains?Or was it from leaning it out, smoothing it and adding some timing?
Looks Great!!
PS Hal@IP, yo never emailed me what we discussed, hit me up..

I have an 2003 so it's a non-revup engine. The peak gains up top are mostly do to the exhaust change. It should be interesting to see what it will trap now

 

The last EMS on the car was an AEM EMS, I never got the VTC to work correctly however it can be done (I think SP's version of the AEM works correctly with out modding the cam)

I had and Apex-i exhaust system with 2.5" Y section from the downpipes. I had used the stock flanges that are pretty smalI when I made the 2.5" setup. This time I made the Y section with 3" flanges and tubing that join to a single 4" exhaust system we made. It seems to be working really well.

 

I messed around with the VTC for about 20 runs. The VTC is what brought the torque up in lower rpm ranges. It can be a bit tricky to get dailed in. The power increases up top are from the exhaust system changes. The AFRs are about the same, and I was running lower ignition advance then on my previous tune.

 

does the ecu retain the same factory failsafes for the DBW system

 

Wow-Im about to come down for a tune damn that is great work!

 

The DBW system is completely controlled by the Nissan ECU. The Haltech has no effect on the DBW system.
*yet*

 

Thanks. We can stick your car on my DJ whenever you're ready

 

so its kinda like a piggy back?

 

The unit runs parallel with the factory ECU. It also can run in a pass through mode similar to how the UTEC works.
