I have a 99 cav and a 2k motor and I have a GM charger ready to install.
The dealer installed the 2k motor, however I'm unsure if they installed a 2k ECU thus allowing me to use the reflash.
1. Is there any way for me to tell?
2. Can the 2k motor run on a 99 ECU or would it require a 2k ECU (would help answer my first question?
I have an MSD DIS two inline fuel pump, AFC II and some other goodies ready, however I would prefer to get the flash if possible. Any help is appreciated
(I 'm heading out of town for a couple of days but I will respond ASAP when I return).
Thanks for the help

I'm pretty sure you need the 2k ECU but im not possitive..
If you still have your stock guage in your car. Then you have a 99 ECU. IF the dealer put a 2000 Gauge in your car then you will have the 2K ECU.
when you do an engine swap with the 2.4 you can still Keep your stock ECU. It doesn't matter if it came from 1999-2002. With amount of work that is involved and knowing a dealer did it the just swaped the engine and not the ECU which is what usually happens anyway. Unless you want to do a full 2K swap with ECU it is not needed.

I thought you would as well but is there any way I can tell?
I have also read that it is very complicated to switch ECU's between the years based on wireharness issues. If it was simple everyone would just switch their pre 2k ecu for a post 99 and get a flash. I doubt the dealer rewired a majority of the car just for the motor, but who knows.
Disregard my last post Mylife helped answer the question.
Mylife, I know the difference between the 99 and 2k gauge cluster is in the redline. Can you refresh my memory as to what the exact difference is?
Thanks
digital odometer
is the main differance that you can observe
digital odometer is only on the 2000 plus models
I had a digital odometer in my with my 99 motor prior to the swap. Are you sure?
Chris
Thanks for the help... So I have a 99 cluster (unless I'm getting confused with my Silverado, I have to check tonight)
As stated before I have a MSD DIS II, In line fuel pump booster and Super AFC II is there any other equipment you would recommend?
Does anyone have detailed instructions for installing and tuning with the AFC II? this thing scares me the most out of the entire job.
I want it to run safe and reliable so any tips and or hints would be more than helpful
Thanks again
Chris
use some rapid fire # five spark plugs, the # is in this forum somewhere.
you probably just have a 2k motor with the 99 ecu stuff. as most the stuff is the same 99-2k minus the ecu stuff.
I have a 1999 Z24 with a 2002 2.4L. Still has the 99 computer.
Didn't they make the changes mid year of 99?? So he could already have a 2000+ ecu. What do your injectors look like?

Changes were made to the 99 Engine but they did not put any 2000 ECU in there. If they did they would have had to put the BCM and a guages that would have been similar functions as the 2K guages. I think someone tries to put a 2K computer in a pre 2K and it didn't function that well, I think it was looking for the BCM.

I believe when they went to digital od they went to a BCM. I know of a 99 2200 with a BCM.
FU Tuning
The 2200 are different from the 2.4's. If that is the case the then what you are saying all 99's should have the ECU because all 99 2.4's have digital gauges. One or two people have tried the reprogram on the 99 and it would not take something to do with the BCM they have in the 2000 and up.

No I'm not saying all 99's would take it. The changed were done mid year. Yes a 2200 is different from a 2.4, but GM is not going to change wiring in one part of a platform, and not the other. Now it could be they changed the BCM's in 2000, and that could be part of it.

You may be right. As far as i remember one person trired to put a 00 ECU in a 99 i believe a while ago and got nothing because they want to see if they could run the supercharger. If it is the same ECU may be a different program on it. The radio etc was all tied into the Door chime etc. There were features in 2000 that 99 did not have. The Change the ABS system etc.. from 2000.

Door chimes were tied into my 97 z radio as well. That does not mean nothing. The thing to keep in mind is they got rid of EGR in 99, so different programing was needed, which would have been when they went to high impedence injectors as well. Which is another key to the super charger.
FU Tuning
Some 99's have the low impedence injectors as well. That is strange door chime was not tied into my radio or anyone else i have spoken. Even when it was talked about on here it was mentioned that it was a feature of the 2K+. That is true they got rid of the EGR. Most people have run the 99 ECU on 96-98 because of the EGR issues. Those car did not have and digital guage etc..

I know it has been said some 99's had low impedance injectors, but have not seen one yet. The injector change went with the EGR, and other changes that the 2k's got.
Yeah when I installed my radio in my 97 I lost my door chimes, which was fine I hated them.
FU Tuning
I did not loose mine when i installed my radio. Most people with 95-99 did not loose thier chimes when they installed their radio. Sounds kinda strange the loosing chime thing was more with 2k+

Truly who knows and who cares, because the door chimes was not what we were talking about.

Eitherway no one knows for sure what is in the 99's. Just the transitional year. Some say there are few 99's out there with EGR's but i am yet to see one. I have not personally seen a 99 with low impedence but about 2 people have claimed to have it. No one really knows but GM. May be the final production car for the year may have a different ECU. Eitherway if it is a 99 ECU no reflash can be done. I was hopeful that 99 may be able to have the flash but it can't. I to was also trying to see if the supercharger would work on my car.

I still think it can be done. Just some more research.
