I will definitely keep that in mind , but it definitely isnt the issue im having at the moment. I have several setups running sd with no issues, but are all dbc setups with stock throttle bodies and...
I did put the truck in gear with same results.
Anybody think its related at all to the tps fluctuating 1-2% as it starts surging with the big throttle body?
Just trying to think of anything that...
The log attached wasnt the config file for the braf.
I use the russ k config whent logging that.
Im wanting to do a few more scans to hopefully find a change in raf but its been really close last...
I normally run just the po103 maf high code. Any benefit of running all three? Also it does set the code and into sd mode. I did mistakenly put it on second error. Just corrected it in the tune.
Now...
Cannot keep this motor idling for very long and just slowly creeps into a nasty surge. Have adjusted timing up and down, played with fueling and airflow,Adjusted for the bigger throttle body, and...
SD 6.0l cam , stall. Been trying to understand why this idle is still surging a few 100 rpm. Ive ran the base airflow procedure, iac counts are a little high, and ive leaned it out to the point where...
Hey 6speedblazer, I know there are some ac related tables in the fan control section that could be related to your issue. Might have to do a scan and see if any of that might be related?
Hey guys, im having a problem with my fans coming back on after exiting the highway. If I command them to turn on through scanner they come on. Im using the low speed to turn both of my fans on high...
Ive also narrowed my idle surge down to too much fueling in idle. This cam needs a 16.5 afr in idle to idle evenly. Also Im getting better vaccum with it running smoother and 28 degrees of advance in...
That's understandable and will definitely be checking into it.
*Update* After steadily going through every table related to idle I started to move fueling around and with this big cam I needed a...
Yeah i argued that with one of my buddies that has some tuning experience. I agree with that i think i will stick it at 105kpa . Hmm voltage i havent looked at since its getting atleast 12 volts. ...
Idle surges. I lowered the idle spark range 1 degree and reduced over and underspeed tables. anything else that can cause a 1000 rpm surge?
Seems to be over reacting looking at the log. reference...
Update.. found out there is a direct relation to the tcc brake switch Feed and my problem. Everytime i push the brake it opens the tcc curcuit and the Idle steadily drops. I bypassed the switch...
Ok guys, I have been chasing my tail figuring this low idle problem and come to find out it only idles low and dies when the brake was pushed. This is manual brake setup no vaccum booster relation....
Injector voltage offset maybe wrong?? I believe its stock paremeters
After doing everything mentioned ive been adding more and more fuel to the 90to100kpa between 400 and 800 rpm and have gotten it allot better but now have constant problems with the idle dipping. ...
Thanks for the response blownbluez06. I was trying to get the lowest map value possible with this cam in idle. I lowered it by 2 degrees.
I initially was getting really erratic timing in idle and...
If you look at the trans out rpm you can see when i put it in gear and then the idle gets unstable and the iac steadily rises till its maxed. motor doesnt sound right when this happens...probally...
I have an ongoing issue that seemed sporatic to begin with and now is almost constant. Seems to do it more when warmed than cold.. 2002 6.0 tx giant cam ,turbocharged, 4l60e 2800 vigilante stall in a...
I have everything pretty close. I just dont understand why its commanding 140ish to idle when its not wanting to idle but after the restart in the log, its idling perfect aound 118 and closely...
I have been having a random issue ith the idle in my tune and looking at my last log looks like an iac tuning problem or another issue with the iac.
Nonetheless i would like some more experienced...
I copied the data from a similar tune with same injectors. Is it wrong?they are seimens 60lb injectors. Could that be related to my issue?
Mako
Ok ive fixed several issues and have redone allot of the tune. Im running 60lb injectors. Im still getting a low idle after driving and coming to stop.Idles great at startup and doesnt seem to show...
Im pretty new to hptuners and still figuring out what tables affect what.
Have a 99 pcm running turbo charged 6.0 with a tsp texas giant cam.
Im hving problems with the startup sometimes acting...
Thanks WS6HUMMER . I will see how it compares with mine. I do think my timing is on the high side for idle and have heard bigger cams like lower timing.
