First Datalog after AEM wideband PRA ecu [EP3]

Post by jdouille »

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.

Have you discussed these tuning issues with CPL Racing?

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.

If the issue is intermittent, it could be a wiring related issue, or it could be a tuning issue. You should discuss this with your tuner.

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

Lambda in 4th at WOT look ok. Lambda cruising looks ok. Where exactly are you experiencing the poor running?

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's little differents.

K20a2 EUDM Sp98 fuel
Flowstack, CAI, intake manifol, exaust, Deatschwerks dw65c, RDX injecteurs and KproV4
N/A 240ch

Thanks
