Nice work! So shiv,whats playing the big role as far as the car making more power than the VIII's?Is it the MIVEC or the turbo? Both? Im curious to see whats the difference between the 05's and 06's.Thnaks

 

TrinaBabe- I'm not sure if the EVO 9 ecu behaves the way you are describing the DSM ECU to behave. There seems to be some very immediate and temporary activity between the 3 high octane timing maps. There might be some long term implications but if there is, that's only part of its functionality.

fire-ballz- They could have underrated it for insurance reasons. I think 300bhp is the magic point for 4 door sedans where it gets bumped up to another insurance bracket. I could be wrong though...

RedAustinIX- Yep, like all EVOs, the 9 has the factory fuel cut at 7606rpm. Nothing to worry about. There is also a secondary rev limit (as with the 05s) at 5000rpm. JDM cars have this set at 5500rpm. I bumped it up to 6000rpm.

burningmoney97- Power-wise, I'm not so sure it can go much further. At this poing we're limited by knock at 5000rpm and again between 6500rpm and 7000rpm. I will try to smoothen things out a bit without sacrificing too much power. I'll also spend some more time working on partial throttle mapping since the few tweaks I've done already payed off bigtime. After this is done, we'll get to work on 93/94 octane mapping which should be worth another 10-12whp.

Vishnu_Evo8- If I didn't reveal some findings, I don't think anyone would realize just how deeply we get into these ECUs There's a reason why our ECU solutions work the way they do and I hope this explains why. Before releasing an ECU product for a new car, we spend heaps of manhours testing/refining/developing before it sees the light of day in customer cars. And even then, they continuously get refined as time goes on.

skiracer- Perfect. 270whp on the TT Dynojet translates to a 15% correction. Assuming this, the stock EVO 9 with just a reflash would be making ~310whp down there which is somewhere between an EVO 8 Stg 1 and Stg 1+ as far as what we've seen while tuning on their dyno in SoCal.

Cheers,

On a percentage how much is mivec/new ecu and how much is the new turbo? Be interesting to swap an 05 and 06 turbo to see.

 

Well, you are definitely very close on this based off of Skiracer's dynojet chart, but it looks like ~1.13 is almost dead on assuming you are basing your DD 239whp to Skiracer's Dynojet of 270whp. BTW, his next two runs were both 265whp.

 

You wanna know what is going to be dead on? You and Alfred out on the indoor karting track tomorrow when me and the boys administer the beatdown

bring it!

This is a bone stock IX then, that is impressive, I might have to dump my 03 and go with an 06 RS... You are making the same hp my modded 03 is making, granted a stage 0+ 93oct Xflash isn't a lot of mods.

Yep. It's totally stock. Just an extensively remapped ECU. And on 91oct, it's making nearly as much as an 03-05 with full exhaust, cams and gears

-shiv

 

I don't know how anyone can say these results are not amazing, from timing and fuel alone.

From what I understand you have not played with the cam yet?

As a IX MR owner. if I was ever to get my car tuned, I would like to have someone with your skill tune it. Forget that, when can I sign up?

Shiv, is it the turbo, the exhaust or the mivec that is helping with the power?

ECUTEC is SICK!

 

Hiya,

We have not played with camshafts yet. Still have a bit more research to do now that we have MIVEC to complicate matters in that respect. But I did remap the MIVEC tables with good results. As for the big power gains over the XIII, I think they are due to a bit of everything. Hard to put my finger on any one thing in particular. I still have a good deal more work to do before it is ready for realease. As far as ECU mapping goes, it is essentially a new platform. And with that comes a lot of time on the drawing board, road and dyno.

Cheers,
shiv

 

I should have listened to my pops and waited to trade my 03 for the IX instead of another VIII

 

Hey Shiv, I just remembered this and don't ask why lol. I was reading through all this and remembered when I purchased the American Touge video to see your car hauling *** and something broke down loll. I was like ...COME ONNNN! hahaha. I still can't believe how much power you guys are making. Keep us updated Shiv

Another update:

I took the opportunity to subject the car to SMOG station today. We conducted a test-only smog just to see how tailpipe emissions are effected with the ECU remapping. My concern was that our revised MIVEC mapping may push pullutants over the threshold. Well, they didn't

Results (idle and 2500RPM test):


HC readings are about as low as they can possibly be. CO readings are well below the threhold as well (0%!). CO2 readings (higher the better) are also very good. In fact, anything above 12.5% is considered good for the environment. NOx readings are not applicable since you need load to generate NOx. We'll conduct another test when we put the exhaust on and remap it again.

We'll also conduct some testing under load with a AWD dyno to get the best possible picture of the cummulative effects of the upgrades. We're hoping to make 390bhp while still maintaining stock or below stock level of tailpipe emissions.

I'm watching this thread like a hawk, KEEP UP THE GOOD WORK!!
I will deff give you a call when it's time to tune my 9.
Shiv you are a dedicated man and we appreciate all this work!!

 

freakin awesome, can't wait till I get my IX, i'll drive up to norcal just to have you guys tune it shiv!

 

Unreal

Put a tbe exhaust on the IX and tune her ASAP.
