Rotrex S/C k20a3

[chrisvang209]

For other s/c k20a3 out there base or civic si

i have a couple of question regarding my tune, originally i thought it was great with just what i had at the moment. But then after looking at the calibiration that we were using i notice 3 main faults i guess it was miscommunication.

cal-states i have 650 when i really have rc 750cc injectors

cal-3bar map sesnor (netronic) and i using a motec 3bar mapsensor

cal-vtec windo is at 4.5k to 6k rpm i believe after reading alot of conrad(clubrsx.com) tuning guide on the k20a3 it should be set lower

I didnt get a chance to look at other stuff such as cam advance and etc because my sister took my laptop without telling me i am going to get it today.

Please hondata guru help me out here.

(side note: i already called the tuner, i believe it was a honest mistake because there was alot of noise when i was giving him the info on what my set up was)

here is the dyno picture i took

It is plainly obvious that the vtec switchover is set way too high for optimal performance. As long as the map sensor reads ok in datalogging, you should be fine. The injector size will only throw off the duty cycle reading, and possibly the throttle tip in, depending on if that was adjusted seperately or not.. I'd get the car re-tuned anyway.

After think about changing my tune i have opt to make a date with a very well known tuner of hondata kpro. I have made a appointment to see shawn church at church automotives to see if he can ease my constant thought of possible better numbers with the current set up. At 2pm this coming saturday i will be getting a new tune from shawn church hopefully i will recieve better numbers.
