Evo VI Dyno

R. Mutt · Posted: Thu May 07, 2009 1:37 pm Post subject: Evo VI Dyno

I decided to post this up here as I'm looking to share with the local evo community. I've been working with Silvermike in preparing his evo VI over the last few months. He finished his build and was looking for an affordable means of engine management. I recommended swapping out his VI ecu for that of a VII and reflashing the vehicle...as you might have seen I sell the hardware, software and technical support for users to take control of their vehicle in terms of diagnostics and efi tuning be it a new or old model evo.

Up until recently tuning a cp9a meant one of two routes: piggyback "intercepting" or full blown stand alone management. The former quite affordable and simple to use but potentially dangerous given the side effects as a result of altering the MAF signal. The latter, while a very powerful route, is also quite expensive and may offer no knock protection. The stock ecu processor speed is 4 times faster than than of an aem ems, and allows you to control all aspects of fuel, timing, boost, knock and diagnostic control.

Mike's ecu was swapped out for that of a VII (thanks go out to dgobo for providing the ecu at a reasonable price). The wiring was very simple and the car started without a hitch. The ecu swap does produce a single p0135 check engine light but this is common to the swap due to some voltage irregularity with the front 02 heater circuit. The CEL was easily resolved by modifying one of the periphery bits in the ecu.

Although you can now tune the stock VI ecu via the openport 2.0 cable I prefer the versatility of running more pervasive rom id's that are well defined and have great technical support in the evo community. For those already familiar with reflashing we are using the 98640014 ID very common to the evo VII.

After a few weeks of street tuning we hit the dyno yesterday. The car was tuned the car for about 45 minutes in 94* Trini heat and came away with 341 whp and 320 ft-lbs

I don't think these are crazy numbers by any means so please don't think that's why I'm posting. It's more about showing progress of a project and to provide the results thus far. The car is running a stock IX GSR turbo @ peak boost of 23 psi holding 21 psi to redline on straight premium pump gas...no methanol. We'll be looking to tune for meth and race gas in the near future and see just how much she can squeeze out of the stock turbo.

I have some video of the runs but can't edit it until I get back to NY. Here are some pics of the car, I'll leave it up to Mike to talk about his setup.

strong numbers on pump!

when u ready to crank that boost call me.... Laughing

Nice build... Nice pix. Thanks for the post Mutt. Congrats Silvermike.

320 WTQ / 341 WHP with Mitsubishi

E9 turbo on straight Premium is pretty good.
Do you guys still use HKS 272 cams? What size injectors?
Can you post a "Spec-sheet" with a list of parts used?

Any pix of the actual "build in progress"?

Mod list:

Evo ix turbo
TBE
Blitz sus filter
AMS FMIC with custom 2 1/2" piping
AMS 680cc injectors
HKS 272 cams/ fidanza camgears
Fullrace prostreet manifold
Forged 2.0L
Stock intake mani/ TB/ head
JDM E7 ecu
Coolingmist WMI ( not hooked up atm)

I am pleased with the results on straight pump. I think given the consevative tune we did, the numbers represent where I think the car should be.

The next step will be to regap plugs and shoot for higher boost on meth

Below is the log of the very same dyno run posted.

Peak engine load is @ 276 around 5500 rpm. At this point boost started to taper.

The IDC tops out just about 85% holding a l11.2:1 afr. The car didnt seem to like the leaner afrs. Tho I know several other evos tend to like it a bit leaner. Could have been due to the heat.

Thanks guys. I just got the dyno footage back from the video capturing company here in Brooklyn. I'm converting the mpeg-2 to avi for editing in Premiere Pro and After Effects. Look out for a video on Sunday or thereabout.

While I've been back to business as usual in New York, Mike is still hard at work tuning the evo. From what I've seen in the logs, I believe he's making even more power with his most recent tune.

There was some room for improvement in terms of the AFRs during spool and following on through to redline. Also a common mistake when tuning is to forgetting to adjust the cells you hit during a shift. Mike has done a great job of cleaning up the timing map to account for this so that timing doesn't "jump" suddenly between shifts. I wouldn't be surprised if the car is making over 350 @ the wheels right now. Very Happy
