I have same problem After mapping, not all time
When i press thé clutch, engine RPM down very fast.
Same problem with iacv ans not iacv well it's not problem.

I have a " WOT compensation fixed at lambda 0.85 (12.5:1) " enable in Closed loop advanced it's normal ?

Have you resolve this problems ?

Because i have a similar questions.

Hi.

On my map, VTEC kick at 4200rpm not 5100rpm and normaly the target lambda curve it's 13.2 AFR curve and on Datalog i see
between 12.5, 12.8 AFR régulary and pic at 11.46 it's more rich...

I do not understand that the target is at 13.2 and that I can read more than 12.5 it's little differents ...

Hi.

On my map, VTEC kick at 4200rpm not 5100rpm and normaly the target lambda curve on my map it's high 13.6 or 13.2 AFR curve and on Datalog i see
between 12.5, 12.8 AFR régular and pic at 11.46 it's more rich...

I do not understand that the target is at 13.2 and that I can read more than 12.5 it ...

Hi.

On Datalog WOT 4th, 5100rpm as pic at 11.51 afr, it's very rich for natural aspirated and stock internal K20.

See at 22s and 1.10m

And the afr its not linear,clean, he is very cahotics.....

thanks

Okey, but have you see any problems on Datalog ?

Because on WOT 4th it's very slow and rich, Lambda is very high compare to my target at 13.2 I 'm not an expert but i's possible any leaking, intake manifold or bad fuel pressure or electrical problems..... ????

Thanks

Okey, but have you see any problems on Datalog ?

CPL RACING have tested my ECU with other car and tune without any problems. Perfect ecu and Kpro card. I made two maps a year apart with
similar performance, 240ch and 230nm on Dyno. But on the road it's stange comportement.

For what ? have you see an problems on Datalog ?

thanks.

Hey Hondata team's

Following my intermittents performance problems, before and after mapping.

I installed an AEM 30.0300 wideband on analogic plugs for totaly delete OEM narrowband. Here are the results with the AEM.

What do you think because I always have an irritating and unstable car ...

Hello.

Did you find a solution ?

Because I just got this AEM 30.0300 probe to replace a oem narrowband on a PRA ECU and Kpro V4.

My schematic is correct ?


Thanks everyone.

Today i have a same problems.

I don't understand, i have compare EP3 full stock with my EP3 240ch and he turn very good power !!! compare to me.

I have unpluged and disabled secondary oxygene sensor for just us Primary every time, no change.... There are days it works very well three times in 1 ...

Ok, disable in Kmanager but unplug wiring secondary sensor from exhaust ?

My goal is to use only the first sensor for all time.

Thanks

Thank you.

My tuner has mapping my car with this wideband to him.

I just wanted to know if in Misc I could use only the primary narrowband and disabled, remove from exhaust the secondary sensor.
Normaly the EP3 PRA ecu will be turn correctly with just primary narrowband ?

Thanks

Hello.

Kpro will be return to my home. Verdict to diagnostic, it's ok for ECU and Kpro, no problems. He tested my ECU in other car and reprog perfect.

The problem is in my car, mebaye wiring or harnais because the fuel pump relay is very vey hot when engine started and WOT.

Other question, with ...
