I've seen some good gains on the dyno from advancing the map a bit at peak trq and smoothing it out from there. It gives more area under the curve.

 

is anyone still advancing it from 0 past 6500rpms?...ive yet to seen any power increase from advancing it there

 

Can someone get me a good screenshot of the JDM IX RS MIVEC map? The screenshot in this thread is low quality, I can't make out some of the values. Plus I set my definition wrong on the JDM IX RS map I've downloaded -_-... thanks.

 

If you try turning your monitor's resolution down to 800x600 or 640x480 you should be able to read the JDM RS map clearly.

 

Didn't work.. -_-. Still hard to see values

 

Here is what I gathered from it.. I'm guessing on the darker colors..



Someone with the actual map, please verify?

 

Red and Purple cells are the only things I'm questioning.. is purple 4.8 and red 9.6? Thanks..

 

This is what I'm using, base from the RS mivec.

 

Here are the cam engineering values for the VIII with stock cams:

IVO 19* BTDC....IVC 61* ABDC
EVO 57* BBDC....EVC 19* ATDC

This equals the cam specs in the cam spec thread 260/256 ... 111 intake centerline/110* LSA

This is the engineering for the IX per the 2006 Mitsu service manual.

IVO 0-30* BTDC....IVC 80-50* ABDC
EVO 58* BBDC....EVC 18* ATDC

As you can see 0* is 9.5* cam degrees retarded from the stock VIII (0*-30* vs. the stationary 19* of the VIII). If what I have been told is true the stock VIII cam made more power everywhere with cam gears cranked -5 (cam degrees, or 10 less crank degrees). This means the stock advance map would be at 9* at peak advance (19-10=9). I am also with Razorlab, 28.8* degrees advance tapering from peak torque makes for nearly big block torque.

 

Does anybody have the full RS ROM they would care to share with me?

PM?

 

It would be even better to get the RALLIART FQ-340 or FQ-360 Mivec and fuel maps.

 

They dont seem to be much different to be honest...at least the 340...I havent seen the 360.

 

I have a 340, but no map for it as the previous owner had it Ecutek'd. Aaron, do you have a 340 map or can you tell me what the differences were?

 

Swapping my old MIVEC map from a Tuner 's Map to the JDM RS Map (Copied load cell values from Page1) It seems my "Airflow" is peaking out a little later now.. Both have same boost. Same road, close weather.

Old Peak: RPM 6062.5, Timing: 7, Load: 229.77, Airflow: 1603.95 (Old Log)
Old Peak: RPM 6063.0, Timing: 7, Load: 231.00, Airflow: 1603.95 (2nd Old Log for accuracy)

New Peak: RPM 6156.25, Timing: 7, Load: 226.65, Airflow: 1603.95
New Peak: RPM 6281.25, Timing: 8, Load: 221.67, Airflow: 1603.95

Not sure why I gained timing on the last log but .

I'm going to now see if the new mivec map will allow me to add more timing below
6000, thus making peak airflow be attained sooner? Does this sound right, or am I way off ?

 

What mods do you have?
