P15UL T Posted July 7, 2008 Share Posted July 7, 2008 i am looking to find out if our zeds are all "drive-by-wire" type throttle or direct cable type ? cheers Paul Quote Link to comment Share on other sites More sharing options...
Stew Posted July 7, 2008 Share Posted July 7, 2008 I thought they were all drive by wire. Quote Link to comment Share on other sites More sharing options...
Chris`I Posted July 7, 2008 Share Posted July 7, 2008 I thought they were all drive by wire. +1 - have a look behind the throttle pedal - you'll see the potentiometer (the variable resistor type thing?). No mechanical cable Quote Link to comment Share on other sites More sharing options...

Chris`I Posted July 7, 2008 Share Posted July 7, 2008 An interesting thing I did find mind, is when I have my OBDII hooked up and pedal flat to the floor, it only ever says 88% throttle. Think I'm being robbed of 12% throttle somewhere Quote Link to comment Share on other sites More sharing options...
Stew Posted July 7, 2008 Share Posted July 7, 2008 Hmmmm, interesting. Was there a deadband at the top Chris? Quote Link to comment Share on other sites More sharing options...

Stew Posted July 8, 2008 Share Posted July 8, 2008 Deadband....... When you push the pedal and nothing happens. like did the readings go up straight away from 0? Quote Link to comment Share on other sites More sharing options...
Chris`I Posted July 8, 2008 Share Posted July 8, 2008 Deadband....... When you push the pedal and nothing happens. like did the readings go up straight away from 0? Ah I see, like play in the steering. No it increases as soon as you so much as wave your foot at the pedal. Any kind of pressure on the pedal will register as 1-2%, actually moving the pedal a few mm/cm gets you from 5-10%. What I would call half throttle (feels half way to me) is about 30% and full whack to the floor is 88%. Tried this morning to do it while driving and gave the same values. I wonder if there is some kind of built in overhead in the throttle in that if there doesnt seem to be pulling enough air it can open it further, but doesnt atm as it gets max airflow without it. Thinking that because it caps the power for us (damn clever ECU!) it doesnt ever need to open it all the way? Quote Link to comment Share on other sites More sharing options...
Stew Posted July 8, 2008 Share Posted July 8, 2008 Sounds like it to me. Hmmmm, I feel cheated! Quote Link to comment Share on other sites More sharing options...
Chris`I Posted July 8, 2008 Share Posted July 8, 2008 Sounds like it to me. Hmmmm, I feel cheated! Me too. The other thing I was thinking was to try one of those booster things that I think 3FIDDYZ has that attaches to the throttle pedal sensor and fiddles with the signal to give supposidly better response (by basically multiplying what you do to the ECU) to see if that would give me a higher reading. Hmmm...... Quote Link to comment Share on other sites More sharing options...
teddyonholiday Posted August 26, 2008 Share Posted August 26, 2008 There is a throttle pedal and position sensor reset in the Manual it will clear the 12% loss. I will try and post the full procedure later when I return home if someone hasnt already done so. Teddy. Quote Link to comment Share on other sites More sharing options...
Stew Posted August 26, 2008 Share Posted August 26, 2008 do you have a link or anything to this????? I'd be very interested in doing it. Quote Link to comment Share on other sites More sharing options...

Curerntly using DashCommand (digital dash generator) and Centrafuse (has an OBDII plugin). Both give throttle percentage. One thing I am still sceptical about is what the number actually means. Will try a throttle reset at some point and see if that gives us 100%. I doubt it will, but worth a punt Quote Link to comment Share on other sites More sharing options...
dcash5 Posted August 26, 2008 Share Posted August 26, 2008 WHERE IS THIS UK SERVICE MANUAL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! THIS IS SECOND TIME TODAY ONE WOULD BE USEFUL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! or are you guys just using the yank on that's stickied?

teddyonholiday Posted August 26, 2008 Share Posted August 26, 2008 Dcash5 I have the original 350 ESM and also the first European version (US doctored) and I refer to them as many of the electrical functions of the european model differ from the US and/or the JDM. As for the reset procedure it is actually posted in the Guides Section too. http://www.350z-uk.com/forum/viewtopic.php?t=10881 Quote Link to comment Share on other sites More sharing options...
Beavis Posted August 26, 2008 Share Posted August 26, 2008 Will try a throttle reset at some point and see if that gives us 100%. I doubt it will, but worth a punt Will be interesting to see Quote Link to comment Share on other sites More sharing options...

The tps reset procedure will not help in this case - only thing that can be done is a reflash of the factory ecu to allow full opening of the blade Quote Link to comment Share on other sites More sharing options...
Stew Posted August 26, 2008 Share Posted August 26, 2008 So we are being robbed of throttle then! Quote Link to comment Share on other sites More sharing options...
Adam@Z1auto.com Posted August 26, 2008 Share Posted August 26, 2008 slightly yes - I had this fixed on my car back a number of years ago, as part of a reflash I had done. If someone feels like donating their stock ecu for a few days I can see if we're able to do it for a UK/JDM spec car as well Quote Link to comment Share on other sites More sharing options...
