Haltech Platinum Pro R32 Gtr

[<<<this guy]

Hey there! Need some Aussie love here!

I am in Canada first off.

The short story is I got a new Haltech Platinumm Pro ECU installed and tuned. The guy did a great job and got me 398HP with a single turbo and injectors on stock internals on 17psi I believe.

Anyways there was no codes on my ETS before but now I get a code 21 (throttle sense). I get a 4wd light on the first start of the day but every other start in the day no code. When light comes on yes I get 2wd only. I have followed the manual to trouble shoot but everything checks out -

replaced tps

replaced ets

and wiring must be ok because the fault only comes on with the first start of the day. Turn engine off and restart many times after and no fault

Sooo to my question and what I am working on.

TPS input I set to .5V no throttle (in the tuning software) and press throttle to floor and hit set and comes to 4.8V ish

The tps input filter recommends 5 I believe and have tried 0 to 8 and 21 code still pops up.

TPS output setting I just found which is the setting for signal out to the ETS in the trunk. I just set the filter to 10... I started once (cold start) and no code but this is nothing new its intermittent.

Soooooooooo I guess the main question would be has anyone know of someone that had 4WD issues after new ECU and what would be a safe setting for the TPS input filter and Output filter??

Please ask around for you aussies have been playing with these cars alot longer than us haha

Thanks

Same problem here except I cant get the light off. Also TPS error but on r33 gtr.

Problem disappears with stock ecu.

Did you find a solution to your problem?

I have the very same error which just recently occurred.

Car was recently tuned (E85 flex tune) with Hatlech Platinum Pro Plug in ECU

4WD was working then badoontish the 4WD light came on last Sunday as error code 21 TPS or circuit error

I also replaced the TPS with a brand new Nissan item and still same error code 21

I will get to the bottom of this as I think the Haltech TPS output setting may be outa whack

I will keep you peeps posted

Found the solution to my issue.

Was relatively straight forward.

It was a ground wire in behind the car battery (also grounding the battery wire) - it wasn't grounded

Gave it a good clean, a new bolt and 4WD light gone and the front torque gauge works perfectly!

Check your earths people. It may be just that simple.
