Im pretty sure we fixed this a few weeks ago in one of the updates. What revision is on your Predator?
I have the 9r13 revision. Even with this update, I was getting the P1128 - 'Calibration Memory'. I was told to datalog the TIP, and see if there is something wrong with that. Like stated before, I downloaded the 93oct tune, car felt amazing, added fuel to be safe cause I hear it's been making the SRT-4's run lean. Had knock, took some timing away, had it pretty good. Running a narrowband till I get my wideband next week. Everyone kept saying that we should hook up the white and red line...so I did after a week of running without them. And always got the P1128 when cruising around, maybe at 0 boost or -3 vac. Uploaded the new revision, and still. Now I'm running off PCM controlled boost, and since no one really knew what was up, I just disconnected the lines, and no codes. Car still feels pretty good, a lil sluggish since I had to pull a little timing due to knock. BTW, I got more knock with the stock pcm at 17psi than I did with the 93oct tune. I have it down to 1 count of knock...and only happens in 3rd gear at around 5600 (where timing peaks to 27 degrees and then settles down to 23), 4th gear is fine, and timing is 21-22 degrees in that gear, and in 5th. All with 1 degree pulled and added 3% fuel in 5-6k. I was running stage 1 pcm before, sold that to get the Predator. Mods at the moment if you need to know...stock pcm, forge motorsports wga set at 17psi spike 15 by redline, fuel pump rewire, 1 step colder plugs gapped at .38, msd wires stock coil, 2.5" dump with high-flow cat, no vac lines, DCR oil mod, um...everything is pretty much non go-fast parts (clutch, sts, k&n filter) Also, the first time I uploaded the 93oct tune, my wga spike went up to 19 on it's own, and 16 by redline. I never touched the wga before or after. After I reflashed the stock tune and then back to 93oct, it hasn't done it yet. idk what other info you may need...i've saved all my datalogs, just don't know how to post them up here for everyone to see.

explain...? I was told to hook up the red line from the cold side, and the tip to the solenoid. what else should I try?
ooh ok i know the tip line does not like vac its a boost source only line but if its in the cold side pipe thats fine
ok...so ya, i have the TIP (white line) going to the solenoid, and the red line coming from the up pipe going to the solenoid....
Pulling timing will hurt performance. Think about this... before the DS. If you boost past the map sensor limits, the pcm would freak out and start to pull timing hence causing the vehicle to run slow. This is why a SRT-4 running 20lbs with say Stage 1 vs another SRT-4 with the same mods but running 17lbs will end up beating the other SRT-4 running 20lbs. Another reason why people run water/meth injection is to increase timing and reduce knock. You don't want low timing.
My timing when I was Stage 1 with bolt-ons at intial WOT it would be 19 and increase up to 28 in timing. Some have gotten lucky and have gotten in the low 30's. Now I went into the Aeroforce timing thread and whats odd is everyone is within the range I was and some like I said in the low 30's but one member with DS posted this: So my question is why is DS running low timing on these cars? Just odd because of the timing concept that has always been with the Mopar PCM's before any flashing device like the DS was developed.
Here's some more interesting information I've gathered... But if you read onto this: So now my question is: With the DS will the PCM adjust timing like it does from factory or is it the timing that is set through the DS is it and you have to keep adjusting it accordingly? Reason I ask is because Juan (KrazyRdr83) says he's getting knock at 27degrees. Around the range our PCM's unflashed have a lean condition which I've seen when I had my wideband and I've seen on the dyno. So if the PCM does what its suppose to do, when knock is detected it should pull timing in Juan's case it doesn't seem its doing that. So I can see why he reduced timing now but he's saying the car feels sluggish due to pulling timing which is what a non-flashed PCM will do on its own and when it pulls timing the cars performance = slower.
idk...i'm hoping someone from DS can chime in...hence why i posted in this thread. i would reset my timing to 0, may do that today, or just wait. only have 1 degree pulled. and like mentioned above, at 27 degrees, is when i get that one count of knock thanks Jesus for you input, good info. what bothers me is i'm only at 17psi spike and drop to 15...and i get more knock with the stock pcm
Have you discussed your issues at all with our tuner Brian? Hes on the SRTforums generally? If not, I'd ask that you come to our forums and post up so he can try to help you out. You can post your tune and log files on our forum as well. Thanks Mike
i've briefly mentioned it to him, said my 04 would be the first with that issue, and made that new revision. but it kept happening. I was going to PM him, but will wait till after the holidays since he's been out of town
