We dynoed my friends stock k24 accord before mods and after mods couple of day ago it picked up 30whp and it leaned so much that the AFR is almost 13.5 now. here is a pick of the Graphs overlayed. Mods were PLM CL9 Header and Skunk2 Megapower Exhaust.

 

just use TSX 07-08 ECU + FlashPro for TSX to tune it properly. Always start from ECU management and then install all bolt ons. AFR 13.5 is too lean....

 

Very good results!

 

it's bad result as car is not tuned properly ! It has power dip when VTEC hits....

 

Actually you are wrong..The Car isn't tuned at all in anyway..Stock ECU. I've posted the graph for all Euro owners as reference for gains with H/E not for OMFGAWESOMENEZZ.

 

and have wrong AFR.... as I said tuning must be done with proper ECU managment in first step. BTW I have CL9 Euro with better I/H and Hondata FlashPro ! With proper tune you gained much more !

 

that right there is WRONG info!!

my 100% stock k24a2 runs 13.2-13.6 afr for and entire race tuned on kpro....

 

13.2-13.6 is a little bit too lean for K24 engine you can ask any reputable tuner and they will say the same!!!

 

13.2:1 is definitely not to lean, and many engines respond very well to 13.2-13.4 afr on pump fuel (when the CR is pretty low).

13.5 is a bit on the risky side since it might get even leaner in certain condidtions, but I doubt it is a problem on a stock engine with stock management.

Off course the result would be much better with a proper tune, but the results are still good given the little work that was done.

 

Quick question..your saying k20a2 in the cl9...im wanting to add a k20 type r top end, but struggling to find someone in the uk who is capable of remapping it, ive been told to get a tsx ecu the 07-08 ecu as this will accept the flash pro, any help would be appreciated!
