This is the response from ZZP after I already told them I checked the service numbers and I was sent the wrong PCM. UUUUGGGGHHH!!!:

Can you tell me what the service code is on the box we sent? Should start with 125, if it does, you have the right box.

Then let me know what the sticker we put on it says. I’ll check the revision.

Sounds like they dont know that it needs a 03 PCM.

Yeah they knew. When ordering the pcm on their site it askes which yr engine. I chose '03 and Fiero platform. Now theyre saying they don't know if they don't have a file for the '03 PCM use in Fiero, but he's going to try to figure it out and get another PCM out to me so we'll see.......I think it will work fine. The car is running on a '03 PCM now so why wouldn't it....

Just tell them u want a refund.....At this point they should not be trying to figure out things..With what they checharge there should be no excuses.

Dont let them try to send you another one... there is basically a 99% chance they wont take out the correct stuff.

I guess they already shipped me another PCM..... We'll see.....

Here are the claims with the 1.0 re-flash

http://shop.zzperformance.c.../74-ZZP-1-0-PCM.aspx


The ZZP 1.0 PCM gives you the most requested and sought after features in a PCM.

Description
Additional Information
.

Buying from ZZP ensures nearly instant response on emailed questions, fast turn around, prompt core refunds, and a phone number you can call if you need to. The ZZP 1.0 PCM is backed by a company you can trust.



FEATURES:
•Speed limiter removed
•Raised rev limiter
•Raised shift points
•3-1 and 4-2 skip shifts
•Programmed for race pellet added timing
•Transmission line pressure increased
•185F fan turn on
•90 second fan on at key-off (this feature activates when engine coolant is 180 degrees or greater)
•MAF calibration is year specific
•WOT fueling richen to reduce KR
•Removes lag by changing downshift tables
•Correct VIN number programmed in (if put in note section)
•Part throttle KR issue fixed
•Torque abuse modes are modified to eliminate bog at launch
•Shift KR is remapped for modified vehicles
•Power enrichment tables modified for cars running increased boost
•P0128 code removed for running drilled or 160 Tstats on newer cars
•Torque converter lockup tables modified to improve transmission life and eliminate converter lockup hunting
•Fiero PCMs have all codes deleted for use in the Fiero, 1.0 features, security disabled, ABS disabled, etc (use the year of your engine on the drop down and all 9's for a vin)
•Sand rail PCMs have all transmission settings disabled, all codes deleted that need to be, security & ABS disabled (use the year of your engine on the drop down and all 9's for a vin)

'06 Grand Prix GXP: We can do this vehicle however the car must be flashed at our location because it has a separate TCM that can only be flashed in the car.
PCMs ship within 24 hours of order placement!



NOTES:
•Electrical items are non returnable.
•97-00 GTP: performance shift mode must be selected to enable shift points and line pressure modifications. On all other PCMs, we program in the performance tables to run all the time unless otherwise requested.

•2001 and 2002 GTP PCM's ship with performance shift tables copied into the normal shift table of the PCM. But we do leave the light throttle shifts stock so gas mileage is not reduced. If you want to add the performance shift button to your car, please specify in the comment line and we will leave the normal shift table stock. But you will have to run a wire from your pcm to a switch in the car to activate it.
•Prepaid return labels are available for the lower 48 states only.

Do you currently have DTC codes or is everything working fine and you just want more uhmmf?

No codes or anything like that...
Yeah. Pretty much. It's supposed to help with KR. and torque converter performance and all that so for $200 and no cut knuckles I thought why not....
My last 3800SC had a PCM done by intense racing and it was an animal!!! It did have other mods too though..... I want to do the power log, or headers.., and short stack intercooler so I can run a smaller pulley though...Compared to my last 3800sc Fiero this one has a ways to go. I also wanna do the cam and rockers etc, but I'll have to build up the ambition to drop the cradle ofcourse....,

1.9 modded rockers and springs are easy to do in-car.

I would just add more mods and make the engine bay look purdy . Unless you start changing injectors sizes, TB/MAF, try to get 30MPG, or shave .5 sec off you 1/4 time then your PCM tune will be fine.

hmm Never done them before... Looks like the front ones may not be too fun......

I was thinking I would need a different cam to do the rockers.... hmm

Man! I'm about to give up on a ZZP PCM in this car.... I finally got around to trying it and it immediately throws codes: p0480,481,530,650,1546,1637,1653,1670
On the upside it does feel peppier and shifts are definitely firmer. I'm not going to have to reset DTC's every time I drive it though. I emailed ZZP to see what they want to do now.... It is the right PCM this time, just looks like they forgot to disable some stuff that the fiero doesn't need..... UGGGHHHH!!!

Stop messing with ZZP and tell them u want a refund..No ifs about it....Tell them they have failed twice.amd.that they should take Fiero PCMs off their list.

Yeah def not good business to claim you do PCM's for Fieros and don't have a clue... I would have thought before they sent this last one they may ask some ?'s about my set-up but they just shot another PCM out instead... By the looks of those codes they just have to do with Fan relays and such. I'm guessing in Fiero form the PCM must not control fans for it to be throwing those codes??

The factory PCM monitors electrical connections to the fan relays and many other outputs. If it does not see the expected voltage on one of these circuits, it will set a code for it. In the Fiero, the fan relay can also be activated by the HVAC control panel if you press any of the A/C buttons (it was not like this in the car the 3800 came out of). If you do this with an OBD2 PCM not programmed properly, that fan relay code (and other codes like it) will set. Sounds to me like ZZP doesn't know what needs to be done to the programming in a Fiero swap. I would recommend you have somebody on here (like me or somebody else) who is familiar with tuning PCMs for Fiero swaps just program a PCM for you.

If I ship it back they'll delete the codes.That is there offer from here out. No refund!... Is my car wired wrong, or should these have been deleted in the first place? The PO did splice in a switch to activate the Radiator Fan....? But my other PCM doesn't seem to mind... There all codes to do with fan relays, etc.. Not happy

I would push for a refund or retract the payment.

If you paid with Paypal or a CC then I would go thru them to get a refund....There should be no reason they should not refund ur money for there lack of knowledge....

I just want to make sure it's not throwing codes because my radiator fan has an override switch... Seems that the codes were mainly for fans..... and the other codes he said didn't exist?? Doesn't make sense. Maybe I'll just file a charge back because I think I did use paypal....

The factory Fiero wiring for the fan relay has it set up like there IS an override switch stock (but it is just activated by the HVAC control panel instead of another switch). Anyone looking at the factory wiring diagrams for the Fiero would have seen this. I can only assume ZZP doesn't have much experience tuning PCMs for Fiero swaps so they probably don't know these codes need to be disabled. They are also going to need to disable the code for the A/C relay because it will set due to the way it is wired up in the Fiero from the factory.

They must not... I'm going to tell them they shouldn't advertise that they do the performace PCM for Fieros when they do a half assed job... Takes three tries to get it right... what a joke.

who are you dealing with over there? I can try to give one of them a shout later if they are giving you the runaround on this.

"Turbo Tim"..... is who has been emailing me. I stated that they must not be familiar with programming PCM's for fiero swaps. I also asked them how many tries this is going to take and haven't gotten a reply yet..

ill see what I can do.

I did an L67 swap on my wifes 2004 impala. I bought an entire powertrain from a 99 regal.
When I swapped I remember having to decide whether to use HD trans versus stock,amd due to wiring differences chose the 04 non HD because of simplicity and keep with stock SS wiring etc..
I also had to rebuild her trans very soon after and did alot of research into different 4t65e's looking for the best parts to use for rebuiding.
There are differences between different platforms I know,as the her tune caused me issues when I used the regal HD diff in it.
I read everywhere that they all had Certain ratio and tuned accordingly,turns out buick got a totally different ratio.

I found this with a quick search,and think it might help with your issues.
Apparently 03 Bonneville is different trans than any other year bonne somehow.
Didn't read entirely,just skimmed. But saw reference to 2003 soecific trans and something about differences in shift wiring.
http://www.bonnevillepro.co...opic.php?f=28&t=5054
Might be as easy as telling ZZP the correct application ie it's a Bonne trans and not a GTP.
If pins are different (you did verify GTP versus Bonne right?) then PCM will be programmed accordingly.

Just some ideas,good luck and hope you get it figured out!

Yep, I explained all that to them... The second PCM they sent worked fine. Now it's just throwing codes for fan relay's that should have been disabled....

It sounds like they are using you as a test bed. Some how they don't have a problem taking your money and time to develop a product.

The car def feels more powerful with the ZZP PCM, but I'm not sure they know what to do for the fiero platform... I just sent mine back again. We'll see how it goes when I get it back. This will be the 3rd attempt.....

Well I hope it will turn out the way you want it to be.
And if they don't will u get your money back or will this go on
Till they got it al right , with a flawless bin file and used your PCM as a Ginny pig

Then they can say : selling a PCM for Fiero engine swaps

Yeah,,, If I woulda known I'd have to jump through hoops I woulda used someone else... My last swapped Fiero had a PCM tuned by Intense racing and it ran great!! I figured since ZZP offered the same thing it would work just as well, but looks like I am wrong...
