Yes, I believe MrFred has that info.

Anyone willing to take a swing at this?

 

No one knows how to log MIVEC yet. Mrfred simply plots the values from the MIVEC table. If you use his HP/TQ calculation Excel file, you can find the MIVEC data on the far right side of the spreadsheet.

He did mention he was looking for the address to actually log it while working on the boost variables ...

 

Could somebody please post up the Radical map image as well as the JDM RS map image...the links in this thread seem to be either dead or unclear. I would be more than happy to host both images.

 

You're right, I was posting this in a rush between cars yesterday. oops!

 

What is that HUMP 4700-5400 rpms?

is that from mivec?

 

If you could parse these two maps together to make a better map what would you change?

 

Jeff, I would make all the 28.8's from 2000 to 3500 30*'s and run it from 70% out to about 240%. I would crank the advance at 6500 and 7000 that is now 0* to 6.0-6.6* and up the line of 4.8 to 7.2 or so

 

Could be timing (ignition) or not quite a smooth enough transition in the MIVEC map. I would probably figure it was fuel or spark rather than MIVEC though.

Another possibility is it was boost doing odd things as it sometimes will.

 

What direct benefit does this have, say if you are running 1.8 bar there?

 

Optimised cam timing means more power. Your results may vary, all depends on octane and total tune to take advantage of it. Sustained top end power but not necessarily more power in all cases.

 

Here is the mivec map that I am using. It is a combination of the radical mivec map found in the Ecuflash forum on Evom and a map given to me by John Bradley. All thanks to John Bradley for allowing me to post this map.

I simply put them together and adopted them to 91 octane gas use. Basically above 6000 rpm I zero out the mivec completely. I did not find much power difference between advancing timing above 6000 and zeroing it out. My car became more knock sensitive when mivec timing was advanced above 6000 rpm. Since gas pices are going down, I am hoping that 100 octane would fall back to $4.99/g. I can go back to mixing for 93 octane and see if advancing the mivec above 6000 rpm with 93 octane gas helps the top end.

The spool up in this mapis fantastic. At the low end 500-3000 rpm it is like driving an NA car. Just shift at low rpm to the next gear and it pulls. The only downside is the idle goes up a bit. in normal driving it stays around 800 rpm. After hammering on the car it hovers around 1000 rpm. But I have a cure for that with another map that lowers timing advance in the idle areas, but it is not as snappy as this map.

 

IRT ^ I noticed when changing low load Mivec variables I could hear and feel the car change when putzing around town. I didn't care too much for that.

I'll probably keep the stock JDM lowend profile for daily driving and switch to a more aggressive map for lapping days.

Thank you John and NJ for posting the map

 

so by giving positive values to cells for 6500 to 7000, you can keep more power to the top end but it can make the car more sensitive to knock? is this correct?

 

I just tried the map in post 297, but left advance in the top end as I always run some octane booster, and the car feels great at part throttle, I am going to log and compare loads at and spool, but so far this map feels awesome, the idle is slightly lopey, but mine never stayed at 1000, it always went back to 796-810. Thanks to Mr. Bradley!!!
