Rich Afr Ater Power Fc Installation

[stagear]

Hello everyone! Since I'm from Russia, sorry for my English. I have a problem with the AFR after installing Apexi Power FC (GT-T) on my Stagea 34 (RB25DET NEO). At idle AFR 13,2, in boost too rich AFR,> 10-11 .. On the standard ECU are no such problems at idle 14,7, boost 11-12. PFC installation was performed correctly .. ETC, DATA INIT, YES .. 30 minutes at idle (10 min + 10 min A / C and 10 min demister)
Of tuning only exhaust, air filter and intercooler .. Engine standard. I thought that PFC fuel map similar to that in a standard ECU map..

Thanks!

Drop the boost to 7psi and it the PFC is pretty similar to the stock ECU. At 11-12psi it runs richer.

11-12 is the AFR, not boost .. on boost 7psi AFR = 11-12, and to idle AFR = 13,2

You need to tune it no matter what.

Take it to a tuner, and have the map fixed up.

Two of my friends have the same engines and the same PFC. Before they tuned in to the AFR everything was fine, at idle AFR = 14,7, as well as with the standard ECU.

Apologies, I didn't read your post correctly.

I'm sorry, I use an online translator))

The translator is doing a good job. It was completely my fault.

At idle it should run closed loop and run around 14.7 when the car is at temperature if the O2 sensor is working on both a stock ECU and PFC. Have you changed anything else after swapping ECU's?

Of the changes that I saw only AFR.. As on stock ECU's all right, I decided to return it and look for the information about the problem..

perhaps the powerfc has had the base map changed to the 1 bar base map? i'm not sure if a initialisation will wipe this setting.

Can you explain in more detail? Do not quite understand. thank you

[Badgaz]

Scrap that... I thought the standard base map could be swapped out.... But I don't think it can. Someone who knows alot more might know.

I would initialise it once more and go ahead and tune it unless the PFC has been damaged it should still do the job.

make sure o2 sensor feedback is enabled on the pfc

it can be turned on and off for tuning purposes

this will probably only fix idle afr's

If I turn on the o2 sensor feedback, AFR gets richer ..
