K-Pro for 2004 Civic Type R (Euro) (PRA ECU)

Hello Forum

I'm in the uk and building a marlin 5EXi kit car and heard that i can use Kpro on the PRA ecu to
bypass the immobilizer and get the K20A2 engine running and thats it's fully tuneable. I have a few questions needed to awnser before i send my ecu off..

1. is full throttle shift an option on the K-Pro.

2. the kit car doen't have an carbon canister/active carbon filter, can this be turned off so it doesn't throw up fault/trouble codes if soleniod blocked off or left disconnected. I work on volkswagen's here in the uk and the ecu knows on vw's if there is a flow problem from the fuel tank to inlet manifold if blocked off. Does this engine work the same ??

3. not related to k-pro in a way, i have an engine and ecu ready to drop in but the scrappy cut the loom of at the ecu connection blocks and flush with the engine, i can't find any diagrams on 2002+ wiring, does anyone know where i can look or get information from ??

4. reverse gear lock out? how does that work?? this is new to me!!

I'm afraid I only know the answer to #4. Hope it's still useful.

In http://www.hondata.com/kpro.html it states:
PNF, PPA and PND ECUs for 5 speed transmissions will not operate the reverse lock solenoid on 6 speed transmissions.

Mines a PRA from a 6 speed transmission, even more confused now...

The European Civic Type-R has:
a K20A2 engine
a PRA ecu
a 6-spd gearbox with reverse lock solenoid.
So the PRA ecu is able to activate this solenoid above a certain speed to prevent you from accidentally engaging reverse.
And apparently some other ecu's don't have this feature...

Full throttle shift is possible with k-pro although I haven't used it myself (yet). Check for instance ClubRSX thread http://forums.clubrsx.com/showthread.php?t=316415

Don't know what you mean exactly with #2

Thank you, that is a great help.

Quetsion 2 is about emission control, i'm not sure if it's a uk thing. There is a third fuel line from the fuel tank on most cars, one is a fuel feed line the other is a fuel return line (noticed k20a2 doesn't have this) and the third is a fuel vapour line which goes to a carbon canister to recirculate the tank vapours to use as an air mix and inject them into the engine instead of venting them to atmosphere, to get the kit car on the road we have to pass a strict test to register the car as a new regestration, i know i can block it off to stop the engine sucking in air, but don't know if it will throw up trouble codes because it's not detecting a flow of vapours when operational (this is where i know newer vw's here detect a flow problem) , next option is to disconnect it, but i would have thought that it would then throw up a trouble code because it's disconnect and if it can't programed out the Mil lamp will be on and fail. or we might have to consider finding a place and fitting the carbon canister to pass the emissions rules.

Thanks again for your help.

I'm not 100% sure but I think what you're referring to is called "evaporative emission canister" by Honda. It has a valve controlled by the ecu PCS signal (=Purge Control Solenoid).

Don't know if not using this emissions feature would actually generate a fault code, but if it does I assume it must be possible to ged rid of it by disabling OBDII with the k-Pro / k-Manager.
This assumption is based on the fact that in the k-Manager software you can re-program the PCS ecu output as a simple boost controller.

Yes thankyou, it is also called 'evaporative emission canister' there are some many different names this device can be called, but thankyou you've awnsered my question about removing it, thats brilliant, i've just sent off my ecu now to have the K-pro fitted, Thanks allot for you help.
