Anyone have a quick log they can post of a car just idling? I'm curious what the calculated load looks like and what that parameter is based upon (ie what is the ecu using to determine the calculated load?)

I seem to be having a very similar issue to what chris'maax is experiencing, that just started today, and tracking it down is proving difficult. Essentially, the car will start fine, rev fine, idle fine, etc. when cold. Let the car warm considerably (after 15 or so minutes, so well past the point where coolant is fully up to temp for example ), and it starts acting up - slighty backfiring, won't rev cleanly. Plugs are brand new, as well as the coils. Only reported code is P0300 but no CEL. Let the car cool down, start it back up and it's fine..till it acts up again.

 

Humm.. None yet, Let me go for go for a quick drive I can get you one.

Mine seems like if I run the car hard and then turn it off after that drive, the next time start and take a drive it, it gets a sluggish when I try accelerating. To me it's feels like it’s going in and out of limp mode as I accelerate.
I have pulled the logs with Cipher, but is shows no errors.

Files are attached for you.

thanks for the log...back to the drawing table, your calc. load looks just like mine, so I have to assume that it's ok

support page I saw earlier today but nothing was listed there at all.

 

No prob. Glad to help.
I have been eyeballing your APS 350Z/G35 Single Turbo kit.... I just don't want to jump the gun..

 

yep. was just making sure you'd loaded the upgrades. gl.

 

I pm'd you about my logs. If you need more data just pm me your email. I had to delete some of the data in this .csv file to stay below the boards size limit.

 

thanks - no, have not bothered to do the upgrades, as I don't really use the cipher much

twin001 - thanks, but can't get yours to open

what is weird is I emailed gothchick, since I know she logs stuff constantly, and her calculated load at idle is 0...which makes sense to me. I wonder why mine is at 20% Perhaps I need to do the TPS reset procedure

 

Yeah... From my memory that's where mine is... Let me get some logs of idle values just to validate that my calc load is at 0 at idle, Adam. :-)

 

i get that as well, once or twice my car stalled in traffic and then in 1st gear it just started reving from 0-1 then just stalled then it starts like a champ and acts fine. can anyone help me too with advice???? no ses codes or light
what up grade is need cipher? i just got uprev about 3 weeks ago.

 

did you right click on it and open with Excel?

Wouldn't the Cipher reflash correct any TPS issues?

 

looking at one of my old logs my calculated load it idle is around 24%. The min calculated load is 10% and max is 82%. Don't know what to make of this...?

 

ok - gothchick said she would check for me, so we'll see. If more than 1 person report the load in the low 20's, that sorta tells me it is where it's supposed to be. So the search continues to solve my issue

The TPS calibration is not done via Cipher, it's just a factory reset procedure. I don't think this is my problem though, as mine is clearly temperature related.

 

well adam i think me and you are back to square one lol. I checked my FCON and all of the sensor inputs are fine. I will let you know if i find anything and hopefully together we can figure this $hit out.

I am pissed man. I want to go for a drive because it is finally cooling off down here and the weather has been beautiful so i can cruise around w/ the windows down

 

Jason-style?

Damn Adam... that's crazy that you both have similar problems.

 

you know it dude!


G'S UP HOES DOWN!!!!

 

lolol

definitely odd - 2 different setups but very much the same symptoms. Hopefully I'll get a chance to look at mine a bit more tonight.

I hear ya kid, believe me! This weekend the weather was finally nice, and I had some time to myself...and the car is acting prissy I'm of the opinion it's got to be something stupid - otherwise it would do it from the moment the car starts

 

Adam,

I did a log last night. I think you're fine. I'm also at 19~20% Calc Load at idle. See attached log.

thanks Erin

 

Anytime~ :-)
