Hondata

Update.

I managed to buy a used ECU from an Atom owner who had upgraded to a Syvecs ECU. I returned my ECU to standard map, unpaired my Flashpro, and then paired it to the replacement ECU and uploaded my custom map. Car now drives without issue (although I still need to replace the faulty lambda ...

Hi again :-)

Following on from my last post, I've spoken to Ariel and I'm a bit confused. They've advised that I need to buy the ECU from Ariel as it will be supplied to them from Hondata after being "jail broken." They've advised I won't be able to map the ECU unless it's "unlocked" by Hondata ...

Returning to stock and unlocking the Flashpro from the ECU is no problem.

Do I definitely have to buy a replacement ECU from Ariel? Do they do something to the standard Honda 37820-RRB-316 ECU before installing it? It would be much simpler and cheaper if I could just order an ECU from a USA Honda ...

Another little update.

I fitted a new genuine Honda ECT sensor. Same fault symptoms.

I disconnected the loom from the IAT sensor and inserted a resistor of a specific value to make the ECU think that it was seeing constant 40 Deg C (thereby effectively removing the actual IAT sensor). Again same ...

Ah ok, fair enough. Can I ask what is special about the Flashpro specifically for the Ariel Atom? I assumed its using "standard" Honda K20 running gear. Also, do you know the reason Ariel use an American ECU when it's for a car sold in the UK? It seems overly complicated. I'm sure the engine/box and ...

Thank you very much.

It's bizarre that I need to use Flashpro specifically for vehicles outside North America, yet I have to use an ECU specifically from North America. I really don't understand that, as it's a complete contradiction. How can the non-American only Flashpro work with an American ...

Serial number is FP-SI-INT-24281 "Civic Type R outside North America"

Many thanks!

Hi all, just a bit of an update for anyone interested.

My car went on the Dyno at the garage that originally mapped it for me a few years ago. They "believed" that the issue was a poor/bad connection in a multi pin plug, and after attending to that the car apparently behaved itself on the Dyno ...

Just a quick minor update.

I ran two new additional ground cables, one from the cylinder head and one from the inlet manifold. Unfortunately it made no difference, hondata logs still showed ECT and IAT feeds dropping out intermittently at higher rpm, with VTEC also dropping out.

I also measured ...

Understood, and again, many thanks.

You are correct, originally it ran a JRSC manifold with the associated supercharger, but now runs a MercRacing inlet manifold with charge cooler core for the TVS 1320.

I believe the Atom uses a "standard" Honda harness, so any alterations should be limited ...

Thank you very much indeed for the reply, I really appreciate it.

I've looked at the logs again and thanks to you I can now can see the VTEC dropping out as you said, and the coolant temp and IAT temp both dropping out.

In the "6th gear pull" log, it seems that the VTEC drops out a few tenths of a ...

Hello all,

Apologies if this is the wrong section to ask for help.

I have a TVS1320 supercharged K20 in an Ariel Atom with ID1050X injectors and other supporting mods (chargecooler etc), it has been custom mapped on a hub mounted dyno using Hondata Flashpro.

The car has started loosing power ...

I don't know precisely, other than the issue must have been due to the CPL map. I don't know if it was something to do with the fact that they used an unsupported calibration method, or whether they just didn't map it properly or did a really bad job. Because they deleted the map I paid for from the ...

Have you managed to eliminate the rev hang?


Yes I have!

Torque Developments International remapped my car for me and completely transformed it. The rev hang issue has gone, throttle response is superb, no more misfires and logs show no more detonation. They were extremely helpful and open, and ...

Hi there i'm a bit concerned about your experience with your tuner thought as you had bought a flashpro and paid for the remap it became your as even on identical cars the map wouldn't necessarily give the exact same results. Anyway all I wanted to say was I had my fairly standard gruppe m intake ...
