Hondata

hello

can anyone see something wrong in my maps or datalog?
i have a 2l LSvtec tuned outside the car after the engine was completed, but when hitting vtec the car just bogs and A/F shows rich mixture. and poor acceleration

another thing is that the PLX guage and hondata A/F readings have a split of 0.6 where hondata shows highest reading

i know the builder tuned with SMSP big tube header and i use an RMF new drag style header and full exhaust, could is be that where the problem is?

It needs to be tuned on the dyno in your car with your parts. You need to set the offset correctly on the closed loop tab so that the AF readings match.

well, the car runs better when moving the vtec xover up to 6000

is the high speed map not tuned right then?
