Another EFI conversion question

There are Air Flow Meters on both the B1 and B2 models of GPz1100's. They are of different designs. According to the schematics, the B1 model has an associated sensor while the B2 does not have a sensor associated with the Air Flow Meter. Another day and another factoid. :blink:

As it turns out...I was looking at the exploded diagrams supplied by Kawasaki when I made the above statement. I 'ground-truthed' the presence of the Air Flow Meter last night and partially dissasembled my '82 1100. Despite that Kawasaki includes it in the on-line parts list and diagram, my bike also does not have one. This is not the first error I have detected in the on-line 1981/2 GPz1100 data. I will be inclined to double-check things from Kawasaki pulled from their on-line material.

My 82 KZ1100B2/ GPz does not have the airflow meter. The computer on the 82 is the same as the 83 and 84 models. The difference between the 82 and the 83-84 is the fact that the computer has a light to transmit codes. They are interchangeable.
The 81 KZ1100B1/ GPz has the airflow meter and it also has a larger type of computer. It will not accept the computer from the newer models. The system is very different from the 82-84 models.

Now that we have that settled, what are we going to argue about next

You know, if this keeps up we are going to know more about these bikes than Kawasaki does :laugh: :laugh:

No Steell, I won't let this thread die:woohoo: Actually Fujimoh, you have returned it to my original question..do you have knowledge that the 1983/4 computer/FI/harness/etc etc will work on the 1982 model? This leads to the Kawasaki on-line info which states that the computer part number for the '81 is 21175-1003 with a replacement number of 21175-1004. This same information is repeated for the 1982 year model. According to Mother Kawasaki then, the '81 and '82 use the same ECU's. The 1983/4 GPz1100's have a part number of 21175-1007. Are we looking at another error on Kawasaki's part?

I stand corrected on my last post saying the 81 computer was diferent than the 82. I have a computer for a 81-82 gpz 1100, one for a 83-84 Gpz 1100. The only diiference between the 81-82 computer and the 83-84 computer is the code light on the later model.

I was mistaken about the 81 computer due to the fact that I was thinking of another computer I have for a 1980 Z1000 Classic. My mistake sorry about that. :blush:

Is everyone totally confused now???

You bet!

There has to be more difference than just the light if one year uses an AFM and another year don't. A fuel map based on temp, rpm, tps, and AFM, is not going to know what to do if the AFM signal is missing

Any computers that are based on rpm. temp. and tps should be able to interchange with others based on the same inputs, AFM based computers will only interchange with other AFM computers.
If it uses an AFM then it's mass air, if it don't then it's Alpha-N, that's two different modes of operation.

I'm talking about the 81-84 GPz1100 models, other bikes are different, some use a combination of Alpha-N and speed density, while others strictly use Alpha-N, I'm not aware of any others using mass air (although there may be some).

No carbs....keep the FI,
