I just finished modding a PC-V for a friends 1st GEN,he already had a PC-III but he wanted the dual maps,autotune etc...

It's really a relatively easy thing to do,I spent more time thinking what to do than actually doing it... :badteeth:

Side by side




PC-III has a separate plug for the tps input,which PC-V doesn't,it's the white 3 wire plug,on the PC-V those inputs are on the main grey plug...



Checking both devices with a multimeter and my initial suspicions came out to be true... The brown wires on the PC-V are a simple loop,same for the black wires on the PC-III...So I just need to identify the coloured wires,thankfully dynojet has the same colours on all the PC's,so it's easy to follow...
Here you can see that both devices have the exact same plug,but the pins are in different locations...


So I just rewired the PC-V plug to match the PC-III... PC-III on the left (used as a guide) and PC-V on the right after the rewire...



As you can see I left the grey ( tps) and black/white ( sensor ground) wires out. I just made two more loop wires and pluged them in their location.

Then I made 2 extensions for the grey and black/white wires and using posi-taps I connected them to the tps...





Next step is to fit the autotune...More pictures on the bike soon... Dynojet should have done that a long time ago... :heyyou: Here is a short video showing everything connected...





As you can see in the 2nd video TPS is not yet set up properly,and you can see that AFR is stuck at 9.99 because my battery is not fully charged and cannot heat the sensor immidiately.Having a fully charged battery is a good thing to do because autotune draws a lot of current ( 3 Amps),and if it's not working properly you'll get wrong trims...
I would also recommend that you download the latest software for the PC-V,which is version 1.0.5.8. It has some nice additions,I will explain them later... Most important are the cell tracer,that you can configure the map switch and autotune on-off switch indepedently,meaning you can have 2 maps and autotune at the same time.




EDIT 22Well here are the schematics. They are very raw as they weren't ment to be public,just to help me.

I will try to explain what you see here,anyone has any questions please ask.

This what the 3d GEN PC-V looks like when looking the plugs from behind.





And this is the rewiring you need to do,so that you can install it on a 1st GEN.

Now the tricky part. There is one small thing you need to take care of. The B/W and Gr (grey) wires are not a simple loop,but a "T" connection when you buy the PC-V.




We don't want that because the tps plug is located elsewhere on the 1st GEN,so we need to cut the wire that goes to the PC-V,make an extension for it and using a posi-tap "steal" the tps signal and sensor ground from the tps plug,right above the 1st cylinder throttle body.Something like this... (note that I left the other wire in place to act as loop-wire,this is the easiest way to do this).





And this is where you need to connect the two extensions you made.





I know my write up is a mess,but if you have the PC-V on your hands you will understand everything,it's very easy actually... :mrgreen:

When doing my 07 PC3 to 04, I cut out and re-used the servo motor connectors to act as the junction,then just hard wired the servo motors.

I just installed an Ignition module from a Zx6RR to the Gen1...coils,same, white wire tagged into the ignition pickup.....simple as that.

Gotta love the simplicity of mass production....decoding what wires do what was the biggest mystery, as you stated too.

Very interested in this!.............so this is a fly by tune?.meaning..I can hook up an O2 sensor on my akra header and the PC5 will autotune it to keep it within a set A/F ratio?.........I'm subscribed also!!

Yes,you can hook up the autotune device which controls the O2 sensor,and connects to the PC-V.

Then,you enable the autotune feature through the PC-V software,set your target AFR and let the autotune device built a map.



dynojet research said:
New for the PC V is the available add-on Auto Tune 2-cylinder module which allows for live, closed loop EFI tuning. Based closely on Dynojet's new Wideband Commander 2 it features a OEM quality Bosch Wideband O2 sensor.
The Auto tune module allows users set a demanded air/fuel ratio in the Power Commander V software and the Auto tune will make adjustments in real time. When enabled there is an AFR table with the same 250 RPM increment resolution as the fuel table. The Auto tune can be configured for minimum run time before live sample as well as maximum +/- fuel adjustments in relation to the base map.
The Auto Tune kit can also use the Dynojet map switch or any open/closed switch which allows the user to switch between live tuning to the parameters set thru the PC V software or the base map in the PC V unit. You can leave the map switch in "live" mode, or if you want to write the fuel map you can connect to the PC V software, retrieve the fuel trims and either write them to the map or clear them. We have also compared several Auto Tune derived maps to dyno tuned maps and the results were impressive.

You can also use the wideband 2 module as an autotune device ( actually autotune it's the same device as a WB2 minus the ability to drive a gauge). Using wb2 gives you the advantage of monitoring the AFR live through the gauge,while the device is autotuning...
(rep to dynagrego & madmax for bringing this to my attention)

I'm using the very same setup on my gixxer,and it works like a charm... I will soon replace the stock dash and wb2 gauge with an MXL,and I will see the AFR live on my MXL dash ,as the wb2 has an analog 0-5 output.






REP'ed for an excellent job mate :thumbsup:
Thanks!

that is very sweet. reps to you :thumbsup: so this means i can probably do that with a Bazzaz setup as well. i have the bazzaz tc replacing the regular bazzaz fi on my 08. was going to sell it but now i interested if i could rewire it to make it work on the 05.

Also can anyone buy only the wb2 without the gauge?
To change the dual maps on the pcv you need an LCD (lcd100 or lcd200)?

I have an XML on the gen1, you won't regret it !!!

Do you need to weld 2x O2 sensors on the gen1 exhaust, or one is enough?

Why weld 2 bungs? Hamaguchi exhaust already has a bung installed so I didn't need to do anything on the exhaust...
Even if you have 2 bungs,you can't use them at the same time with 1 sensor :badteeth:

You can always dive into the deep of individual cylinder tuning using 4 sensors and a datalogger,and then adjust the mixture through PC-V for each cylinder separately... But that is just too time consuming if you are tuning alone,and the benefits for a almost stock bike like the most out there would be minimal...

Or if you have the cash you can buy a Motty AFR tuner and it's expansion unit,and let it work it's magic! :idea:

But the cost would be almost 1500 €... :badteeth::badteeth:

Ι know! I got one from bayboy and it's already here waiting to be installed! Just need to get an extra harness...

Bazzaz is quite different,as it plugs directly on the injectors and the coils,I installed a ZFiTC on a 3rd Gen once... ( lot's of wires :lol: )... 3d Gen ZX 10 has 8 injectors,1st Gen only 4. What are you going to do with the extra 4 injector plugs? Will it work without them connected? I don't think the injector plugs are even the same between the 2 models... Lots of things to worry about,+ the autotune of the bazzaz is not as good... A lot of people have issues with it... I thing this unit exists mainly for it's traction control,if you don't want that then go the dynojet way...

I find it very challenging,at least...

so my question is with autotune will i be able to switch between e85 and regular gas. will it be able to pick up the differences???

If you are asking me,I'd use the autotune to make 2 different maps for the different gasolines.

Then I'd removed it,and change between the maps via the map switch. I don't want it making adjustments all the time,bike runs better without it.

I feel interested in the PCV Ignition Module. Is your guess that it can be adapted as well?
I would upgrade my whole PC system in that case.

Great work so far. Congrats:thumbsup:
I am sure he will sort it out :thumbsup:
But the new IM should fit right in the pcv ? :dontknow:
Edit: Do they use the white connectors now?
