Hondata

Hello, we are in the process of swapping a k20c FK8 engine (with wiring Loom and oEM ECU). Which version of flashpro I will need and what ECU I should have? Does Euro FK8 ECU work in this case?

Hello. I am tuning an FK8 with xdi evo fuel pump, DW300c rear pump and 1530cc injectors running about 2bar of boost.

Xdi 2bar boost.fpdl

I have seen that DIFP falls at high rpm/boost. If I lower the boost, problem still persists but it shows up in gradually higher rpm. I suspect the rear pump ...

Ok, although I really doubt they can help (car is not located at the US at the moment). If I were to dig a little more to the problem, do you have any suggestions about where to start? (after checking plug and wiring of course).

Problem is that it also has Hondata fuel system so not easy to revert to stock.

ANy chance this could be linked with a 'money shift'? WE replaced the intake camshaft with the notorious trigger shift issue and we interminttently get this CEL (mainly during cold/overnight cranking). We also replaced chain and tensioner and also exhaust cam gear. CAn this be attributed to oil ...

Hello. I have an intermittent P0369 (most of the times CEL triggers on cold starts). Have replaced sensor, nothing changed. The weird thing is that I have also disabled this CEL in hondata menu but it still comes on. ANy ideas?

Is there a reason you haven't activated this mod?

also, if it's indeed a Euro FK8 then shouldn't it be using a Euro FK8 calibration? Or is that not a problem? I honestly don't know, just trying to see what could be the issue.

Both have been addressed in the ...

No boost does not decrease.

Hello, are you sure? Isn't this the air charge limit?

Hello. New upload with 4.2.3 firmware. Only changes to the car -> pracworks carbon intake manifold

Tune modifications -> increased turbine flow and wastegate flow by 20%

Results -> I still cannot increase BPCMD at high rpm. But now another issue arised-> BP is less than BPCMD.

I am not sure if I ...

I see what you mean but I did not turn off a single DTC. After your remark, I started a calibration from scratch (euro 2018 FK8) and used all stock settings in the first menus. Exact same DTCs were disabled automatically from the list!

However if I start a new US FK8 2018 calibration, all DTCs are ...

True. I tried first increasing flow 20% only to see same boost levels but large difference between WGCMD and Wastegate position. So I reduced the values again by 20% (so overall flow rate table where a tad lower than before).

I have not altered the Wastegate position tables though, I do not really ...

Hello Hondata, tried everything, nothing really changed. I only managed to increase BPCMD a little by decreasing intercooler and air filter pressure drop tables to almost zero. This way, BPCMD increased to 25psi at high rpm with a good jump in power. Please check last tune and dyno log.

Yes, looks like it. I can't increase BPCMD at high rpm above 23-24 psi even if I remove all limiters and increase torque request and air charge limit. Hondata, any ideas?
