Dynoflash- Evo X tuning results thread
few questions since i like the handheld option:
can the AP control in/ex mivec?
control over stock boost controler? (i have a EBC but many people might have this question)
control over fuel and timing?
fuel injectors, maf table, final gears (when that market is available) red lines, speed limiters, rear 02?
are increments based of % or points ( a lá diablosport or a lá apex) <----off all the ?? i hope you understand that one
basically total and absolute control

Yes
Depends on the table being tweaked
Today I had the pleasure to dyno tune my first Evo X with the new Access Port pro tuner for Evo X. I have had the Mitsubishi pro tuner for over a year but not much action with it until now!
the subject car is a 2008 Evo X
AEM enclosed box intake
Forge UNOS MBC and WGA
Buschur Cat Back / Quiet muffler
Bost peak 25 psi
93 octane
With the car 100% stock tune and the above parts it made 328 whp and 301 TQ
I flashed in the off the shelf Cobb Stage I map (not really for the car with an intake) and picked up some great power 350 whp 331 TQ - that was 22 whp gained and 30 TQ gained. The Cobb base map is very good. Their tuning is well evolved to match the more strudy engine of the Evo X. As always great.
Next I proceeded to fine tune or pro tune the car and tweak the timing and fuel maps
Results were 356 whp and 345 TQ with the Dyno Flash custom map
Here is the dyno sheet

The Cobb AP worked really well - no bugs - no problems - no bricked ecus - it was all smiles on the Dyno Flash Dyno !

Should take a look at the boost level of 26psi Evo X are hiting once the aem intake is installed alone
We had the opportunity this week to tune another few 2008 Evo X's in house on the Mustang Dyno AWD-500.
This particular car came in already equipped with the AEM intake system.
The first pull on the dyno we aborted due to excessive boost (in our opinion) on a stock BCS (boost control solenoid) vehicle. (or so we thought)
The boost spike we aborted upon rolling into the throttle was 25.8psi before we let out which we assumed was a result of a problem with the Evo X's boost control system.
We soon learned that along with the AEM intake system's cone filter and airbox, enlarged intake pipe, there was also something very interesting.
We found that the boost control line from the stock BCS which is SUPPOSED to tee both of the outputs from the dual solenoids into a single line back into the intake snorkel was in fact modified by the AEM intake kit.
AEM uses TWO BCS inputs into their intake pipe in conjunction with large hoses designed to increase vacuum onto the smaller BCS lines. The stock BCS lines have the tee removed and not only are they connected individually, they also are connected to AEM's MUCH LARGER intake lines to "suck" the boost control signal to the wastegate away from the dual BCS's, decreasing the signal to the wastegate and increasing boost tremendously.

As previously stated, we aborted the pull due to the boost spike so it could have very well kept climbing.
AEM claims +16.67whp and +17wtq according to their ad, with the addition of 6psi of boost from their BCS vacuum hosing alone sold with their intake, this is concerning.

____________________
OK, so being that we had deemed 25.8psi and climbing to be excessive, we proceeded to cap one of the two lines to the AEM intake-BCS solenoid lines so that only ONE BCS solenoid was being forced to allow additional boost through.
Here is the result;

As you can see, there is still a peak of 23.8psi which is a few psi more than stock, but not so much as to max out any 25psi boost gauge on the market.
The AFR still appeared well into the rich side of things at 10.3 AFR or so, however the ignition timing appeared to be a bit on the high side with the AEM intake.

Here are the dyno results of the AEM with boost hike by the AEM boost hoses included with the AEM intake.

After the disappointment we had with the AEM intake raising the boost without a boost controller or ANYTHING we decided with our customer that the AEM he bought elsewhere was coming off and the stock intake was going back on.
This is especially concerning for anyone considering a mail in reflash of some kind. With a tuner adjusting the boost control tables higher, on top of the AEM intake raising the boost to 26psi or so, that is a recipe for a certain unhappy result.
_____________________________
Moving on, we swapped out the intake after working with the aftermarket boost hoses for a little while and deciding against continuing along that path.
Our final ZChip tune datalog on the car is shown here:

Here are the dyno results with Forge UNOS boost controller and ZChip tuning on the STOCK INTAKE, not the AEM.

And finally, the graph overlay of the AEM intake and 23.8psi to the STOCK intake at 25psi peak tapering down on a Forge UNOS MBC.

We have found the AEM intake to be one of the best on the market in terms of its cold air routing and isolation from under hoot hear and air turbulence which creates rough idles

I'm currently running Gruppe M intake, which only replaces the factory air box while maintaining the stock MAF sensor and stock turbo inlet in place.
I also have the ARC intercooler and piping installed. The size of the intercooler is similar to stock, and the piping size are 2.25 inch through out.
Is the Stage 1 map considered safe to run with this setup?

With the AP or any reflash of the stock ecu the stock ecu and wastgate solinoid can mainatin sufficient control over the boost for most applications
I always pefer to have a seperate boost control - just personal preference

I cant seem to upload the original dynos but here they are... My MR
1st dyno : Max Power: 287.12 Max Torque: 298.35 (intake, exhaust)
2nd dyno: Max Power: 294.23 Max Torque: 305.75 (intake, exhaust)
3rd dyno: Max Power: 310.89 Max torque: 326.99 (everything in my mod list)
