Possibly solved,
Just in case someone reads this in the future i may have found the culprit. I came home the other day with the high idle, before anything else I grabbed the laptop and data...
Hello all,
The issue is back today and more consistent. When it idles high i don not have Idle/cool flag

when it idles normal I have the Idle/cool flag.

Any idea what this...
Jay,
Have you been able in the past to get the data/program to work with a PC laptop? Maybe use/borrow a laptop and confirm the configurations are correct and then repeat the set up with the...
Are you trying to data log in tunerpro or make make changed to burn a chip? I data log with winaldl.
Jay,
If you want to PM me you phone number I can walk you through it.

I dislike unsolved threads so i wanted to post, It has been a month and the truck has been running perfect and not one instance of high idle. I guess i will leave as is for now.
If I ever...
I have the $4F mask. At the time i was not confident about installing and possibly repinning a different ECU. If this continues i might try going with a different unit.
I have a CJ build i...
I just replaced the park/neutral switch again because i had no reverse lights. It wasn't that old. It has always been hooked up.
The truck is an 89 and came with the 400 turbo. It has the...
I bought a TBI from this place when I rebuilt the motor/driveline ~5 years ago.

The injectors that came with it failed after a year. The pedal always feels...
Rick,
Thanks for the reply, Are you thinking if it had no connection/fault/short it might default to the -8C setting and through a ton of IAC?
When data logging i have never seen the temp...
Hello All,
everything On my build has been running nice but I still get a random highh IAC count can can not determine why.
1989 v2500 burb, 5.7 TBI.
The truck will idle fine @~650 RPM with...
Mecanicus,
You are saying you dislike the computer controlling your timing?
I will read Eaglemark's write up. thanks for the link.

Hello all,
Not sure if this is the right forum so please move if needed.
I have an AMC 360 in a CJ7, I have been considering converting to EFI but most aftermarket systems worry me with...
Dave,
I am using the bin and $4f XDF file from the link you referenced.
I just opened tunerpro in the office computer and it works perfect.
Yesterday I downloaded TP to a new laptop in the...
Hello all,
I do not do a lot of tuning and Tunerpro is my kryptonite. Seams like every time i use i have issues.
Anyway, Truck hasn't been running right so i pulled the ECM. Was going...
I am no expert but 160/146 is just the max retract for cold start/reset. I just looked at a bin for $42 and it is 145.
I have since re enabled the IAC and set MIN AIR to about 20 counts. I'm seeing maxed out IAC values on a cold start now, 160 steps is max I think??? Not sure if this is normal, anyone know??[/QUOTE]...
interesting observation today,
I am trying to just use open loop for now, Raising the temp for closed loop to stop it from going closed.
Even with all IAC step removed from the available...
Got under the truck tonight and realized i have no wire at the trans for VSS. My year has the green box under the dash. All original, so it is getting the VSS from the speedo. I have been...
BINGO,,,, I just went back and looked at the raw data and the raw MPH is zero. It is interesting what you said about turning off and restarting. I notice that it will be high and then i turn...
I am trying to disable the open loop idle or have it go closed loop earlier. Today it is back to high idle. I am sure it has something to do with the steps added in OL idle. The truck is in CL...
Hello again,
I have been fooling with Tuner Pro and loggin some data. Nothing in my data shows a MAP or TPS issue and the truck is running smooth. I have concluded closed loop for AFR is not...
Don,
You are right, My guess is a faulty wire of sensor. everything is new under the hood but I have had plenty of defects out of the box. The next time it is idling right, I need to log and...
The cam is 207/213 at .050. I have 18" of vac. It idles smooth at any desired RPM all day long with the IAC unplugged. 40% of the time it will idle right even with the IAC active.
