mivec tuning exposed with dll dyno graphs

[fusionchicken]

Here is the mivec map that Fast Forward and I are using on our cars. 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 who post on the Ecuflash forum. 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. At first I thought it was in my mind, but Fast Forward confirmed the same thing. At first he had a hard time adjusting to the driveability on his car. You usually use too much throttle with the Evo to get it going. With this map throttle response is amazing. I kept quiet while he was driving for the first few minutes. The look on his face was priceless

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.

I just got "Looney Tuned" and like gus (Ff) and Naji (nJ1266) reported, its like driving an N/A car... like Gus noticed, I can be cruzing at 30mph on 5th, mash the pedal and its like im in first gear without down shifting.. lol!

dunno about 1st gear, but after my Evo got retuned 5th gear is definitely much stronger :)

dang, btw are you guys running this mivec map with a stock fuel map? or you guys also got your fuel map tuned? im still learning more about the fuel map, and tuned a little of the degree's here and there but i was too scared to make any drastic changes because i didn't want to mess up the fuel map too bad, since we are only running the piss 91oct(if i mess up really bad, it can be bad for my engine LOL)...


btw thanks a lot for sharing your map Fastforward and nj1266, i will try this map out..

My car, FF's car and SR20kid's car have had their fuel, timing, and boost maps "Looney Tooned." "Looney tooning" is the next level in tuning. Looney tooning frowns on the use of MBCs and open filter intakes. It is going to take the Evo world by a stormÂ*

[ohhgyeahfasho]

^^ hahaha nice!..i need to make my fuel map leaner...im still currently on the stock fuel map, and i need to fix it, its too damn rich..

[TeKiZeRo]

Dayuuuuum! After reading this I really want to try this out!

ohhgyeahfasho, did you try using FF's numbers in your table yet?

[ohhgyeahfasho]

ohhgyeahfasho, did you try using FF's numbers in your table yet?

yes, and what they speak is the truth. i sent the my table with some modifications from FF's map to my friend who's running 93oct 30min ago(hes in Central time zone, so it was like 2am something) he got out of bed, flashed his ecu and logged his car and ran around, he was very pleased on how it was so responsive in the low rpm, and he also said that he noticed more kick in 4th and 5th gear..tomorrow im going to test this on 91oct, with 2 cars..Evo IX with my first map and Evo IX with FF's map+some tweaks. and i will log it, and i will test this on completely stock fuel maps. man i wish i had a dyno..

i really need to learn how to tune the fuel maps! hahaha someone teach me! >.<!

[TeKiZeRo]

Awesome! Let us know how it goes. I might do some custom tuning next week after I get my bolt-ons on so I would love to be able to put these mivec changes in to see the difference. What tweaks will you be doing to FFs map?

[ohhgyeahfasho]

i only changed some of the values in the higher rpm and in higher load part, mostly done in the 4500-5500 range..i still need to test them though..so you have a tactrix cable? do you have knowledge in fuel map tuning?

[TeKiZeRo]

Naw, I don't know how to tune fuel maps. My friend will be tuning my car if he's available after the install.

[Evolutionized]

our cars justin and our friend....

cant wait!!

[vortech_g35]

I'll just give you my maps :P, wonder if they would work.

[TeKiZeRo]

I still have your maps on my laptop... I'll take a look tomorrow to see if Alfred altered them :D.

ohhgyeahfasho - Any updates?

[ohhgyeahfasho]

I'll just give you my maps :P, wonder if they would work.

what maps? mind if i take a look at them please? :) whatever map your talking about, i can test them to see if they work or not.. hahaha

[TeKiZeRo]

I have them on my laptop and with Andrew's permission, I can PM them to you.

Anyone know if messing with the mivec settings can cause any potential damage to the engine?

[leaveit2bevo]

Anyone know if messing with the mivec settings can cause any potential damage to the engine?

no as long as its a good tune.

+1

if done correctly your off-boost response will be off the hook, my car seriously feels like a healthy v6 down low right now.

as well expect great spool; the power delivery will feel like an n/a vehicle.

darn mivec

Jealous?

now that's just mean :D
