So I just installed the ZZP PCM 1.0 in my 2005 LT 3.8 non supercharged Monte. While I thought this would be a straightforward install, I've hit a couple of issues, and I'm wondering how I should proceed. I already wrote ZZP about the issues and I"m awaiting a response. I'm wondering if you guys have also experienced these types of issues.

First, I had to do a CASE learn to get the car to start. After 2 complete cycles, it finally started. GREAT! At least I thought.

After it started, I got the SES light of doom. So I took out my scanner and got the following codes. P1664, P0140,
P0654, and P1260. The car thus far seems to be running fine. However, I haven't taking it out for a full blown test drive, because it got soo late.

Aside from the DTC's of DOOM, I also noticed two other things that are pissing me off. My remote starter no longer works. Which is an annoyance. But more importantly, my Oil Pressure guage no longer functions. HELP!!!

P140 is the O2 sensor - bank 2... otherwords the one right behind the cat. I don't have my book on me so I don't know the rest.

For the oil pressure I would double check that the electrical connection didn't become disconnected. When tearing out the intake you might have bumped it.

Short of that I don't know much about their programming.

 

Case learn is different from Security Relearn.

CASE learn is Crank Shaft Position Relearn ir CKP relearn known by some.
The securtiy relearn is the cycle thing you were talking about and when I got my Intense PCM it state "to complete the cycle 3 times". Not two cycles...Approx 30-45 mins. Thats strange though...

I have hearing so many bad things about the ZZP PCM. They have great parts but I question the tuning.
They do hold the World Record though....

 

OK! Update time!

My remote started began working late last night. I randomly tried it and it started again. I'm wondering if the new PCM just had to recalibrate to know it was there. So thats a done deal.

Ok other issues. 1 the new PCM was to come with the Rear o2 delete tuned into it. So I'm wondering if thats just an old code lingering, but then again it shouldn't considering this is a new PCM. Right?

As for the oil pressure gauge. Where would that be connected so I can check to make sure it's all plugged in and good to go. Any and all advise is helpful at this point.

ZZP is working with me on this issues as well, I'll keep you posted on what transpires.

One major questions is, I got the new PCM to get the performance and rid myself of DTC's..and the SES light of doom that has been on since I upgraded the Cat, cat back and downpipe.

Lastly, you are correct. I dide a Security Relearn, NOT a case learn. Thanks for clearing that up! Is it possible for me to do a CASE Learn?

 

^^^^^If you have a scan tool with a special menu, it provably will do it. I had to pay the dealer to do a 2-5 min job... I didn't have the tool. I heard snap on will do it.. I would do it to have your PCM run perfect... Some say it's not needed but it is...

 

This thread is the first clue I've had that there might be some negative opinions/experiences with the ZZP PCM, especially after reading the reviews (http://www.zzperformance.com/grand_p...ews.php?id=182)
I recently purchased off of e-bay another PCM that I intend to send into ZZP to have programmed, as I would like to keep my stock PCM just that, when I decide to get rid of the car someday.

Please keep us up to date, hopefully with good news with the problem being rectified. Good luck!

Hey there, I'll definatel keep all of you guys in the loop with anything I come up with. I haven't heard ALOT of bad about ZZP, and everyone should keep in mind that all cars are different, so what might mess with my car, might not mess with yours.

Also keep in mind that my car is running great after the installation of the PCM. It has more power and you can definately feel the shifts are firmer. However the SES light remains on, and the Rear o2 delete seemed to not have worked. And my oil pressure gauge has flat lined.

I will be swapping back to my stock PCM today, just to see if my oil pressure gauge comes back. The ZZP PCM will likely be going back as thus far the o2 delete didn't work, and i'm getting many more DTC's. But I'll keep you guys in the loop.

 

Thats just what I have been reading....^^^ I personally have not had a problem with them, but I don't run a ZZP PCM...I'm get there tranny though, about $$$3,000+ worth of tranny...[sm=jawdrop.gif]

 

I'll be interested to see if it does come back. I'm curious, does all sensor data get logged through the PCM before going to the gauges or not? Do you have a scanner that you can check if oil pressure is being read, but not displayed on the gauge?

 

Here is that security proceedure you should have followed. Not sure if this is part of it at all.



In the event that your vehicle fails to start after installing the PCM, you will need to perform the Security Relearn Procedure. This procedure allows the PCM to function properly in your vehicle. Follow the steps listed below completely.

Security Relearn Procedure Steps
1.) Attempt to start the car by turning the key to the Start/Run Position.

2.) Observer that the vehicle fails to start and that the security light is illuminated.

3.) Release key to the 'ON/Accessory' Position. (DO NOT turn key to the 'OFF' position).

4.) Allow the vehicle to sit with the key in the 'ON/Accessory' Position for at least 11 minutes.

5.) Turn key to 'OFF' position and allow the vehicle to remain in the 'OFF' position for no less than 30 seconds.

6.) Repeat steps 1-5 for 3 cycles.

7.) On 4th attempt, your car should now start.

NOTES:
- Since this is a fairly long procedure, it is recommended that you limit all electrical sources, such as disconnecting headlights, to prevent discharge of battery.

- It is SAFE to wait LONGER than the allotted time, but it is not safe to wait less time (i.e. 12 minutes instead of 11 minutes should be safe; however, waiting 10 minutes instead of 11 minutes is not safe.).

When properly executed, this procedure should take approximately 35 minutes to complete.
