calibration question

[peshinho]

Javier or matt:


Hope you are doing fine!!

I have a 2007 civic si with strup race header, p2r throttle body spacer, aem sri, toque dumper , skunk2 exhaust and of course the flashpro

the only thing i have tuned with the flash pro is the air/fuel ratio (when the ivtec is on its in 13 aprox, can i take it to 13.2 or it will be too lean?), modified vtec 4750 (lower) / 5900 (upper) and rev limit up to 8800 (is this ok? or it should be lees or can it goes a little bit up?).

** will i have any beneficts if i change the cams angles? (if yes should it be when the ivtec is on, or it can be modified in both "ivtec on and off"
** can i modify the car advance timing as well and get any hp gains?
** what other parameters can be adjusted besides the air/fuel ratio, the rpm set and the ivtec adjustment?

Thanks

We find that 13.0 - 13.4 is a good target for a NA engine.

8600 rpm is the highest rev limit we use a stock engine. You can rev higher on the dyno for testing.

You really need a dyno to tune the cam angles and ignition timing. The simplest method is to compare runs with a baseline, the cam 5 degrees advanced and the cam 5 degrees retarded. Some for the ignition (we use +2 degrees and -2 degrees for the ignition). For more advanced tuning lock the cam angle to one setting, and tune the fuel and ignition for each cam angle.

I will rent a dyno and go and change the parameter you just said.
Thanks a lot, i will povide the calibration and the logs after this is done so you can take a look, if that is ok with you.
Take care
