I ask a favor to anybody who has an HR and can datalog their Intake & Exhaust cams at IDLE

Im having a big trust issue with Uprev right now,
Since I swaped the HR heads into my 370z, I couldn't datalog with Cipher until I tried again today.
I never had problem with the Rom Editor for logging..


so doing a test map I make sure the IDLE area is at 0deg on both Intake & Exhaust Table.

I get this with the Rom Editor;
Intake Bank 1 = 0
Intake Bank 2 = 0
Exhaust Bank 1 = 0
Exhaust Bank 2 = 130

If I add 10deg on both ,, the result is like this
Intake Bank 1 = 10
Intake Bank 2 = 10
Exhaust Bank 1 = 10
Exhaust Bank 2 = 148 (+18 !!)

Then under Cipher datalogging I get this with 0deg in IDLE area Int. & Exh
Intake Bank 1 = 0
Intake Bank 2 = 0
Exhaust Bank 1 = 130
Exhaust Bank 2 = 130

if I add 10deg Exh Cam I get this
Intake Bank 1 = 0
Intake Bank 2 = 0
Exhaust Bank 1 = 112
Exhaust Bank 2 = 111


so I cant trust anything in this.
My Favor is to see what other HR owner gets please .....


edit; the engine idle fine, no DTC, doing a 1/4 mile performance run with my AiM Solo DL , I got 103.5mph which look to be alright for a lightly modded HR engine.

 

only 103.5mph?

 

it was on the street average out of 2 run, not a 1/4mile track prepped on. Its quite different
and don't tell me a relatively stock HR engine with street tire will do much better than 103.5


Btw, this thread it not about how fast I went or 2-3 mph faster with a better driver , but the datalog issues with the Cams so if you have nothing else to share on that topic, avoid posting.

Thanks.

 

Usually the values presented are bigger than actual degrees, in this example i'd assume that what Uprev translates to "degrees" is listed in smaller units in the PCM language, so you are seeing 18 'units' change for a commanded ten degrees. That may not be abnormal.

The fact that it presents two different base values from left to right bank makes me think there is a possible cam sensor communication issue. Are you re-using the 3.7 sensors, or the 3.5? I'm not aware of if they are interchangeable or not, excuse my ignorance. I would assume you cannot based on the VVEL setup being different but anything is possible.

I'd have to guess, if the 3.5 sensors are sending a different type of signal that what the ROM editor is used to from a 370 you could be getting that errant value. Were you getting normal degree values before the head swap?

I know on my HR with my Cobb, the logging/reporting on the screen isn't correct for cam timing either. It stays pegged on one cam at times. I think there is something in the ECM that they don't have fully descrambled.

 

Thank for this comment

To answer the big question about if I used the 3.7 sensor..
no

all sensor connected on the engine up to the ECU, came from the HR engine ... because everything had to be transferred over.

so, after talking with Sasha (SG-Motorsport now Onpointdyno.com)
told me last night that he remember seeing the exhaust cams to be around the number I had. (130deg)

since the ROM Editor doesn't read the same from each bank but under Cipher it detect both side to be the same. .. I would assume now there is a bug into the Rom Editor that Uprev should fix asap.

I'm just quite **** at Uprev because ,, well that ECU/Roms has been around since 2007 ! its not like they couldn't or someone couldn't detect it before ! Or it was just a bad timing on my part that happened to have started tuning on this ECU while a bug/conflict was integrated into the software not long ago... who knows.


Still, it would be awesome if somebody would datalog both of their Intake & Exhaust cams banks at Idle to confirm my possible issue.

 

It's not uncommon for odd issues with uprev. They had to reverse engineer every ECM (multiple per model year and engine type). Also, ROM editor is where they spend all their time these days and Cipher is on life support. Have you contacted Jared about this? He's been fairly responsive (responds within a few days but then communicates regularly) with all my queries some of them pretty detailed. I'd also be a bit curious how your ECM is even dealing with sensors it wasn't designed to work with - and it's not like they spend time testing every possible Frankenstein setup. Just as curious as you are about if it's a bug in the ROM editor though.

 

You'd need logs from a 3.7 though, 3.5HR logs aren't telling you much because the ECU interface is different.

I get Intake cam values pegged at +50 all the time and exhaust cam reports correctly on my Cobb AP, just saying.

 

I haven't send my email to Jared I was supposed yesterday but didn't had time.


I guess I wasn't clear, ...

my HR head swap on the 3.7bottom require the use of the HR ECU ...

so the HR ECU is controlling the engine at 100%.
the only sensor I kept from the 370z were the 2x 02sensor which are use by the HR ECU , same setting.

I currently don't need a datalog from COBB ... only UPREV please.
Thank you for you Input though.

 

Ever figure this out?

 

I didn't emailed Jared about this,
and nobody ever offered any real help about what I asked.

there is a lot of snob peoples that are too busy showing off I guess.

 

Rom editor values are fine. Took a look at my logs, intake follows numerically, but exhaust is different.

At idle:

ICB1 3.5
ICB2 5.5
ECB1 -0.5
ECB2 128

Looking at long term logs, the ECams like to oscillate more than the ICams. Don't forget that adding 10 "degrees" on the Uprev table is really trying to add 5 degrees of actual cam advance. So a swing of "8" on the raw value, is really a +-2 degrees while in operation. You can trust ECam B1 to be the value that correlates best with the cam table value.

 

Thanks you very much T_K about this.

So it prove that my current setup seem to be 100% fine.

 

i have a 370z and i've been chasing an intermittent loss in throttle response.

when fully warmed up, my intake cams are advanced to 34.5 degrees at idle. this is based on Cipher logs. thing is, the engine idles fine with the exception of some rpm fluctuation. other than that, it seems ok. the engine feels flat after 4000rpm though.

i thought the intake cams were meant to be retarded/zero degrees advance at idle?

i dont think it's a glitch because Cipher does show zero advance at idle when the coolant is below 65 degrees celsius.

hope that helps
