Shiv, do you think that a MIVEC retrofit would be possible in the near future for the 03 Evos? If so would the Xede W/SMART be compatible with everything. This new technology for our Evos is just amazing!

 

That sounds complicated and more trouble than its worth.

 

Not necessarily. It might only be slightly more complicated than a head swap.

 

We've been looking into this for quite some time now. We've even determined that the XEDE can be used to control the MIVEC since the VIII ECU can't. More later...

That's quite interesting!

 

By the looks of it, it's not even that involved

 

When people spend $800-1000 on questionable intercoolers and $1500 on turbos which work like stock, a MIVEC retrofit looks a lot more feasible. Esp when it can potentially offer 30-60lb-ft more torque all throughout the low end and midrange.

Sign me up . Faster spool up on my GT30R would be awesome.

 

Thanks for the info Shiv. I would definitely consider doing this. Alot of the Evo owners are talking about dumping their VIII's in favor of the IX. I'm not ready to do that and you have a great possible alternative.

 

Shiv,

If it's not a complete head swap, can you tell us a little more on what hardware would be needed exactly?

I was thinking that a IX head would be needed because there could be:

1. New oil lubricating passages for the CAMs
2. Mounting bosses for the MIVEC control hardware (pump, solenoid valve, etc)

I'm all for getting a MIVEC swap, if it's feasible!!!

 

Shiv,
I called your office today and "presetup" an appointment for this saturday. I had a couple questions before I call tomarrow to confirm it. I wanted to get the xede but it seems it won't be ready for a couple months. I plan on having a different set up in a couple months when you have the xede ready to go. Should I just wait for the xede?
If I get the reflash can you reflash it back to factory when I upgrade to xede? And finally,
Is there a discount from going from reflash to xede, or do we still pay the full amount as if we never got reflash for the xede? Sorry for all the questions but it's a long drive =)

 

EVO9. There sure are a ton of people excited over it!

We tuned BR350 #005 today. This makes the 10th BR Edition car we have built now. Just as a side note -0- warranty issues so far, period.

Anyway, this particular car came in as the weakest EVO I have tested so far. First pull was a horrible 188 whp. Second pull was 196 whp. The car was cold so I figure the warm up of the driveline fluids and such had something to do with the change.

We installed the BR350 package on the car and dropped it back on the dyno. Power went up to just shy of 230, without the tune.

Al came down and we worked extremely hard on perfecting the boost control through the flash. It took us most of the afternoon but the boost curve is now better than I think you can get it even with a manual controller. Even pulling the car in 5th gear we cannot get the boost to spike, just a flat line until the very end where the boost drops to 18 psi.

The end results were great. The car made a best of 276 whp! This is through the stock cat as we have to keep it for warranty purposes. To give you an idea just how much power this is a car I recently tuned with a VPro on it made 286 whp and ran an 11.86 ET in the 1/4 mile.

The other two BR packages we tuned a few weeks ago also made in the 270 whp range but both of them had additional parts on them. This was an exact BR350 package.

No problem. As Calvin probably told you, we don't expect to have a plug-in XEDE for at least 3 months. That's how long its taking to get the new style connectors. Once we get them, we'll make progress very quickly with baseline maps, XEDE controlling the MIVEC, etc,.. But until then, I think our reflash option is the best choice. And even when the EVO IX XEDE becomes available in the future, the reflash may be a better choice for the people who aren't going to take advantage or need user-tunability or map switching capabilities.

At the rate we are going with reflash development, we're generating baseline maps for the IX at a very quick rate. I don't expect updating your ECU for your new future mods to be a problem. That said, i'd say go with the reflash unless you plan on user-tuning. But considering that you're willing to drive down from Washington, I'm guessing driving out to us for custom tuning isn't much of a problem for you

As for changing from a reflash to an XEDE, i'm afraid that they are completely different products. The reflash involves a software license so it is considered a product as well as a service. So that means that if you want an XEDE down the line, you'll have to buy one on top of what you paid for your reflash. This isn't the case with our Techtom-based Xflash from the EVO VIII which isn't Ecutek-based. But I have yet to see a Techtom-based system sucessfully reflash a IX yet.

Hope to see ya on Saturday..
Cheers,
shiv

 

So EVO IXs are still making the same power as the EVO VIIIs on your dyno?

 

It seems that the IX's make, at best, the same power as VIII's on Buschur's MD - Everyone else is claiming somewhat significant gains Maybe someone is not hitting the IX button on the dyno
