Have 05 ram hemi.with u7137 predator.use the lowest octane tune and never had an issue till today.pulled out into traffic while lightly pressing on the gas vehicle went unresponsive then backfired then the lightning bolt between two lines came on i pulled over and turned the truck off.after checking everything out I decided to remote start my truck so I could look under the hood as well as shut it off by remote if i needed.the truck went thru its normal remote start sequence but did not disengage the starter.this type of system has to see a signal off the injector wire to let it know when to release the starter.so appereantly the injectors were not firing.I let the truck sit a few minutes then was able to start it up and drive it trouble free ever since.the only thing ive ever noticed is if and when it messes up the throttle seems to not work the truck feels like the throttle is non functioning and the truck spits sputters shakes and dies.

Thats what the lightning bolt means, that theres a problem with the electronic throttle. Most likely its something simple, like you need a new throttle body. You can get them on eBay dirt cheap since I stopped buying them. Used to be able to get them for under $20 all the time, sometimes for under $10.

Any idea what all the pids mean? So I know what I'm looking at .I got a link before but it did not work.and the instructions did not supply any info.

P061c means " Internal Control Module Engine RPM Performance"

What else do you need the meaning of?

Just wondered what all the pids were i could monitor.not the codes but if I want to record real time data.some are obvious like rpm,map sensor.there's too many to list.I guess I just wondering what they mean if i want to view how my trucks running

For your 05 its recommended that you log these:

RPM - engine speed
MPH - vehicle speed
ACT - Air charge temperature
ECT - Engine coolant Temperature
OPEN LOOP FA - Open loop Air/Fuel ratio
1/1 Short Term ADAP - Short term fuel trim, Bank 1
2/1 Short Term ADAP - Short term fuel trim, Bank 2
1/1 Long Term ADAP - Long Term fuel trim, Bank 1
2/1 Long Term ADAP - Long Term fuel trim, Bank 2
BARO - Barometric pressure
PRATIO - Pressure ratio
TOTAL WORKING PW CYL1 - Injector pulsewidth, cylinder 1
KNK LT RETARD - Long Term Knock Retard
KNK ST RETARD - Short Term knock retard
ACTUAL SPK CYL1 - Actual spark advance, cylinder 1
BASE SPK - Base spark advance
SENSED MAP - Actual Manifold pressure
MAP TO USE - Manifold pressure used in the tune
READ MAP - Pressure the MAP reads
RAW TPS1 - Throttle position, RAW, reading 1
RAW TPS2 - Throttle positive, RAW, reading 2

Sweet.thanks

Ok.recorded all the things you mentioned went for a drive about a minute into the drive it sputtered and tried to die.so I recorded it happening but don't know what to look for on playback

I was suggest uploading the log, so the Diablo guys can see whats happening. They'll know much better then I will.

2.36 seconds into it.total working inj pw cyl 1 goes from 13976.00 to 0 then back to 13976.00 at the exaxt time it messed up

Ok I'm not sure how to do that

You need to do the log on the Predator, then plug it into your computer. Use DataViewer to download the file from the Predator. Then you can view it through that and upload it here as an attachment.

I think this is a somewhat common issue on these trucks, have you checked any of the ram forums?

Not a whole lot but I'm fixing too.I know its not a predator issue just thought if I used it to get data someone on here would chime in.
