So I went to the stealership and got a new battery and had it registered. PROcede was turned off but left in the car as I no longer have a warranty so why bother right???

Now here is the fun part... If the PROcede is on, when I floor it as soon as it gets to 4K rpm, the Service Engine Soon light comes on and the car goes into limp mode. HOWEVER, with the PROcede off, Map 0, the car will pull at WOT all the way till redline and shift. No Problems, and no limp.. pull after pull. THe 1st occurrence was 500 yards from the dealership when I tried to pass someone with the PROcede on.

Once the SES light is on, a short time later it will go off and the car goes back to normal. PROcede off or on. I tried this 4 times before posting....
HPFP was replaced less than 2,000 miles ago.
Should I suspect foul play on the part of the stealership? ie "frying" my PROcede?
What could be the cause of this besides the HPFP? But if it is the HPFP why no problem with PROcede off. I run 10psi stage 1 with K&N filter.

thanks for help

Need to read the codes..

[ptwob311]

yea, I got to go get one of the USB cables... My other computer that had the serial port died

[Wedge1967]

Did you do a full reset on the PROcede?

[OECMG]

Maybe someone at the dealer is playing tricks with you??

I read somewhere there is a way to read out the codes through the tach but I can't find the directions for that. Someone here might be able to forward them to you.

how do you do that?

[Garrett@Vishnu]

The best way to get some feedback remotely would be to get connected with a laptop. Use our User Tuning Interface that is available for free download from our website, PROcedetuning.com. Try to pull any codes and/or run a datalog and attempt to recreate this condition. Also, if you are local to us or one of our official dealers, we can provide further support directly to you.

I have experienced the same case as you, finally it is about spark plugs, just change a set new one and problem would be solved.

[Jeff@TopGearSolutions]

It sounds like you have a misfire, likely related to spark plugs. If they are over 25,000 miles they likely need replacement.

Reading the codes would 9/10 show a misfire. The misfire only occurs tuned because you are running nearly 2x more boost then stock, perfectly normal.

Over time the spark plugs gap increases, which is the cause of these misfires.

However, I would first, reinstall the firmware and software on the PROcede and do a reset.

Step 1: Turn ignition ON, use the cruz control to access Command Mode 3.

Step 2: Once in Mode 3, go to commands 12 and reset 12 thru 1 (12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1 in that order). It's also a good idea to wait 10 seconds once Command 3 is executed (DME reset) before progressing to 2 and then 1.

Step 2: From your USB cable, go to COMMS menu in user software and select "Reset PROcede". This will take a few seconds.

Step 4: Turn ignition power fully OFF and wait 5 seconds

Step 5: Start the car and drive!

codes reveal misfire on cylinder 4. new plugs are enroute...

Good choice. I recommend ordering an ignition coil as well (fairly cheap, $47) to have on hand. I replacrd my plugs 100 miles ago to fix a misfire and it worked until last week, where it reappeared in cylinder 5 only. Then yesterday i replaced my Cylinder 5 ignition coil and it solved all the stuttering/misfires that had reappeared.

Just my $0.02. It might just be ur plugs, but its always nice to have an extra coil on hand in case you start having misfires on only a single cylinder.

PS-Do you have the spark plug socket tool? You need this in order to replace the plugs yourself. Its like $19.99 from BMS

[ptwob311]

ordering the tool tonight. Hoping to have it all back together by Friday for a trip to Houston.

I also just pulled another code 12543 which is an under boost code. could it be spark plug related?
