The truck is still using stock throttle body.

The vehicle has been dropped off at the tuner again maybe he can get it running. I will share the tips you guys gave with him as well to see if that...

Attaching current tune

2014 RAM 1500 5.7L

Just installed a Whipple 2.9L kit and cannot get it dyno tuned do to ETC service error over 3/4 throttle. Base tune has been established with updated injector data and it...

I havent had luck with the newest beta either for EEC-V I have given up and sent the car to a tuner with SCT.

Just do a search for EEC-V and you'll see lots of us have issues with the the 99-04 tuning as well. If I was to start all over I would just go with decipha suggestions instead of trying to get...

Mine has been doing the exact same thing. I haven't notice it filling in accurate numbers during the glitch in my case it just locks in previous value so you get a nice flat line. Cluster issue...

without a stress free datalogging setup it will not be easy to "learn" to tune. Those who have been tuning for years know exactly what is needed so they know the bare minimum that is needed for...

Here is a log of it driving94446

do notice i get random misfire counts on some logs but not others. Car drives fantastic no stutter miss or issues except stalling when coming to stop and of...

did disable egr in tune no change to stft mismatch.

speaking of that it is always bank 2 drivers side showing lean. Same side EGR valve is on, I noticed when smoking the car I saw some leakage at the egr though I thought that was normal. Reading...

No change to bank to bank error. I have smoked intake no vacuum leaks besides at IAC which I believe is by design correct? Also swapped injectors between sides and saw no change.


Also I...

Got the o2s swapped unfortunately could only get a cold start data-log before it stopped working again. See attached log. 94333

Looks to still have some bank to bank error but not so negative. I...

Switched them but of course datalogging for some reason tonight was impossible with hptuners. Getting at most 10 to 20 seconds of data than nothing for 1-2 mins. Gave up tonight I will try again...

Seeing some Bank 2 Bank stft error at idle seems to go away once I get driving.

This normally points to exhaust leak correct?


Car is 2001 Cobra with Comp Stage 2 cams and high compression...

mine doesn't fill in the the space it assumes same data from pre drop out during that phase. O2 voltage etc stay completely flat during the drop reconnect phase.

Anyone NOT have drop outs with...

Anyone found a fix yet for EEC-V constant drop out of gauges while datalogging?
Makes it difficult doing WOT pulls when you RPM gauge drops to nothing.
I also notice this in the raw data as well...

Not many people are utilizing HPtuners for EEC-V vehicles as there are other arguably better tuning options for them. I do not see allot of people asking questions or getting much feed back...

Good Idea i will check plugs when I change the oil this weekend and see what they look like.

I should mention I have an aftermarket throttle body as well as I know that typically can cause some idle tuning issues as well.

Do not see a way to log isc duty cycle. I can log idle...

Finally got some time i try and tune on the car. Recently installed new o2 sensors as 1 was not reading correctly.

I am seeing large variance bank to bank on stfts at idle as well as surging...

Yes, they are suggesting wiring issues with the car. I verified I did not miss any grounds yesterday and It didn't change the datalogging.

I was unable to log anything without drop-outs including...

Ah ok. So look at average LAMBSES in range compare with average WBO2(LAMBDAs) and adjust from there, looking to get my STFTs down to +-1 Correct? Do i need to disable LTFT learning or anything like...

See attached for the tune file as well as log file.

I am seeing the fuel source go to CL stoich eventhough I have high CL O2 temp, is it truly going into CL or is it still in OL for MAF tuning? ...

So starting the journey of tuning my car.

The car is a 2001 Cobra.

It is a 5.1L stroker 4V with 11-1 compression fresh build.
Heads have slight bowl work and freshly redone, Upgraded...

HIDs removed did not eliminate the issues. I will be checking all grounds this weekend as well.

What else could lead to noise in the wiring that I could possibly look at? 02 Extensions? ...
