Thought I was going to keep my mouth shut on this one for a while, but I see a few posts indicating same "differences" that I am getting after a few days with both.

Let me start by saying that weather has prevented anything more than a couple of bursts and no highway driving yet at all on the combo. As I have also read tons on the computer having to relearn/learn the chip and the other way around, I figured maybe my truck was still in Pre-School.

Be that as it may, I am experiencing the following after installation, and I do believe Frank and I did the installs properly.
1. Rougher than normal idle.
2. What I will call "cutout" on really light throttle. Perhaps stumble or bucking is a better description. Just like a distinct engine miss.
3. Idle goes way down when putting trannie in park prior to shutting down and then goes to normal in a second or so.
4. Had some mild detonation at over 3k revs, but that seems to have stopped.

I have less than 200 miles since the change, all at basically under 50 mph., so maybe I should wait until I have had a chance to wring it out, but as I said, others seem to be seeing the same things.

Opinions?
Bill
PS: I love it anyway!!!!

Bill:

It sure sounds like something abnormal is going on there. Mine runs like stock in idle, and would not even know that I have the chip installed until I step on it. I have no ping with what is described to me by Superchips as inferior fuel (Citco).
I'm still in the first 50 miles, and if Mr. Chip has more to learn, I don't know if I can stand the excitement. It will be interesting to see what some of the experts have to say.

Bill,

I didn't think much about it at the time because it seemed so minor, but today I noticed a similar "stumble" with my newly installed PSP chip. The low speed stumble would only become apparent at extended cruise times (several minutes) at below 20 mph with the chip in "performance" mode. If I cruised above 20 it would smooth out and when I switched it to "stock" mode the stumble went away regardless of speed.

I have not experienced any of the other symptoms you mentioned.

I'm thinking it may just be "computer learning" related but if not, I'll be happy to just leave the chip in "stock" mode in heavy traffic and during our current house hunting expeditions (kids are gone; time to downsize) and "performance" the rest of the time.

Other than this relatively minor thing, the chip has been truly awesome thus far.

Bill, did you go straight from the superchip to sal's chip or was there a no chip for awhile? curious as to why you got sal's after success w/superchip, or was it a custom thing, shifts,nitrous, nitromethane . i know the "wintergas" thing had you pinging in #2. you yankees in atlanta ought to move south, where there is no such thing

 

MrBBQMAN:
Try to keep it simple:
Loved/Love Superchip, but did run into detonation problems in mid/late Nov. due to change in gas formulation.
Had been talking with Sal for some time on "custom" program for his chip.

Ran Superchip in normal mode for about 6 weeks. Changed to PSP chip last week and one day later installed filter. Am running PSP chip in Performance mode full time, but as stated, with no serious runs on it.

To be honest, I am more curious than concerned as both chips have been sort of unused for about 2 months in the sense that I have not really wrung the truck out for some time.
As I sit here at about 10;00 PM, we are in the middle of a rather interesting thunderstorm which is, to say the least, unusual in Georgia in January. Therefore, there will be no full bore learning curve 0-100 mph. runs for a while.
Let us just let it lie for a couple of weeks until I can get Moby out on the Interstate and give her her head several times and then I will report in again.
Bill

I have a superchip and experienced both the detonation and the stumble. I went so far as to get an RMA number but have not returned the chip yet. For some reason, both problems went away just a day ago. When I first got the chip, there was no detonation or stumble. It just started happening one day. And, just like it appeared, it has gone away. I wonder if the chip's learning process just takes a really long time.

Also, I had to remove the chip to take the truck in for some warranty repairs. Will it hold the program or will it have to re-learn all over again when I put it back in?

 

i TALKED TO M.TROYER . He says the superchip learns for 800-1000 miles OUCH!! Looks like my truck will be learning for 3 or 4 months.

 

Question: Does the chip learning process have to be carried out with the chip (Sal's or Superchip) in "performance" mode exclusively or does some "learning" also take place in the stock mode?

Hey Guys

Just installed my new chip tonite and i am seeing the same thing with mine. Really notice it at WOT. It only happens in performance mode when switch back to stock it doesnt happen. I really believe it is the fuel we are getting. All i can get around here is 91 octane. The other chip i sent in was doing the same, but ran perfect the first 3000 miles. I am going to try Avgas, which is 100 octain. My fuel tank is empty so will fill up with 10 gal Avgas and top off with 91 octain. Do i have to put oil in Avgas to up the luberative values? Thanks Dennis

Nathan:

I wonder if you just had some bad fuel. I believe Bill mentioned something about the changing of the local fuel formula during certain months that caused him problems. I would imagine that the chip would have to relearn after a power removal. It would be the same thing as disconnecting the battery. Judging from the performance of my Superchip right out of the box, it must not be a complicated or long learning process - my runs incredibly strongly and smoothly.

I think avgas is not unleaded fuel and will destroy your cats. I've heard that some also have a deice agent in them. Its better to get a unleaded racing fuel. Scott

 

Hey Guys

I have had two PSP chips. Like i said before the first chip worked great until about a month and half ago. When weather got a little colder. The last one was just installed last nite.I am sure this Avgas doesnt have deicer in it but will check more into the unleaded fuel thing. Been tring to get some racing fuel but is hard to come by here. Thanks for the info guys. Dennis

 

Hey everyone

I am in NO way running down PSP chip. Because i know how it will perform. Just tring to find out what the problem really is. Will try to find some racing fuel this weekend. Dennis

 

Scottodog is right. Not only will it damage converters, but your O2 sensor as well.
