Hi everybody,
I am looking for infos on how to tune an Honda Jazz L12B2 2012 (keihin 37805 rb2 G160).
I changed exhaust and put a larger bore throttle but now I have plenty of fuel too rich errors at idle and low speed, while at higher speed engine tend to be in lean condition...
So I should remap, but in my area nobody tunes Vtec hondas...the only answer I received was "you can only do it yourself".
Is there anybody that can help?
I heard that many tuners will adapt maps on the fly if I send mine.
So first of all, how can I copy original map to my pc?

Thanks
