ES2 Civic K24a3 swap with PPA ECU

[lexuspod]

Hi Guys,

I'm close to completing my ES1 Sedan 05' Auto Civic to K24a3 6SP M/T.

Im having some issues with either the ECU or Starter or both

Starter isnt engaging with flywheel. (ordered a new one)
Bench tested & starter does spin when jumped but issue still remains below:

Car is auto chassis & key is held hostage in ignition barrel when trying to take out
Ignition barrel also never has been able to turn starter motor on.

Old Engine: D17z1
New Engine: K24a3 (from accord Euro)
Old Harness D17z1
New Harness Base RSX
All ground cables in

ECU: PPA Q04 CRV 04' KPro from RevZone Aus

Error code in ECU logs also:
P1607 for ECU internal circuit malfunction check
(When I go to load up a map file in Kmanager - I dont see PPA so only other option is to go 'other engines' and select the stock TSX map)

Immobilizer is also disabled & Kmanager can talk to ECU/upload/save maps & changes

A little stumped and dont know whats causing the ECU to not turn the starter motor...

Any ideas?

Did you bypass/bridge the old auto box shifter park interlock on the body harness for the starter and possibly the key release from the barrel?

Hi guys,

So, I have some more news - after further investigating/troubleshooting with friends (1 is an auto electrician)

This is the config now:

KPro 04' CRV MT PPA-Q04 (Bought from RevZone Aus)
K20 (RSX Base) engine harness
K24a3 Accord Euro 03' MT Engine
Chassis: ES1 2005 AT Civic

Since first post I have:
1 - By-passed auto neutral/park safety (Key now cranks engine)
2 - On KPro I have immobilser disabled
3 - I have loaded an accord/tsx base map from the calibrations available on KManager

So with all of this, now when I crank the key

- ECU reads, ignition on, online on KPro
- When cranking, I get RPM also on live datalogging on KManager
- No spark

I have bought and replaced the CKP sensor & rewired it.
Ground is confirmed & tested on the harness
& I have also tried both remaining (Sig/pwr) pins in different spots

I still get the error code:
P1607 for ECU internal circuit malfunction check
& Crank position signal error

I honestly think this ECU is not compatible with Kpro with my chassis

the PPA-Q04 I was given by the tuner shop, is it possible this is actually my issue to why I am not getting spark?
I also tested on the harness from ECU end to sensor is wired up to the correct pin on the ecu

Any help is appreciated :)

ok I have a lead - going to try this tomorrow

The ECU you are using is not supported and should not be used as it does not have all the circuitry needed.

Ok so one of the verified retailers has sold this to me & I have explained this to them many times that you guys say its not supported.

I can send it back to them to get it exchanged for another ecu right?

The authorised dealer is RevZone in Melbourne, Australia.

I will use this thread as a reference to them.

Thank you

Kind Regards,
Alex

This will be up to the dealer, but they should install the K-Pro into a compatible ECU.

UPDATE:

CKP Sensor was faulty (bent signal pin)
This explains the CKP signal fault issue I was getting

IAT Sensor was also not wired correctly.

ECU wasnt the issue although I did try a 2nd ECU anyways. RevZone confirmed ECU worked on their end.

Car runs now, everything works well.

Hey man, what base map did you use with the PPA?

I have a PPA with a Kpro 3, I can’t start the car on most maps but I’m not seeing a lot of data from sensors. When I click to data log, the relay clicks like crazy and the car dies
