My Positive Exp Tuning AEM EMS S2 on Stock Turbos/Fuel - 313//337

[bboyalan]

I usually keep my more mild tuning updates to our regional board, but I felt that this build has had a pretty cool outcome thus far.



The owner, Rob, was referred to me through another client/friend in SoCal. After seeing the results with "DuTTch" Mark's VR-4 [560AWHP @23lbs on AEM], he decided to hit me up. I knew that I could not pass up the opportunity to tune a Series 2 from scratch yet alone with a stock turbo and stock fuel car.



Needless to say, I was determined and very much prepared. I was already on my toes from doing multiple GReddy/Link/ECUFlash tunes and such this year with local 3/S, Evo, and DSM cars. The results absolutely surprised me, and I can honestly say that the car drives leaps and bounds better than it did on stock ECU/MAS!





Full boost by 2.8k, crisp DFCO, lean cruise, and she looks/sounds/performs plain mean! The only downside was that I quickly realized how limited I would be from the stock fuel system - completely tapped out! I was amused to learn that shortly after receiving the car back, he had wasted no time in acquiring GReddy 720cc injectors and a Walbro 400lph FP yeeee!!


"313AWHP is the final number - for now! This is exactly what I was aiming for on stock turbos, stock injectors, and stock fuel pump. The gains are roughly +38//22 at the same 1bar boost with pre's hollowed and 3SX DP added along with fine-tuning the AEM of course. I am definitely content despite not having more fuel to work with.

For the record, peak KNKV was ~1.09v =]"

The next possibilities include more boost on Pump-91, 91/100 mix, or Pump-E85 regardless of stock or upgraded turbos. Things will continue to get more interesting to say the least though!







Stay tuned!

Oh! I almost forgot my pre-celebratory breakdance 3/S picture

Gotta love the S2.

Gotta love the S2.

Yess'r! Chris H. and I have been joking back and forth via FB comments about live tuning being the best perk of all; it really is though.

Good shit! You know my opinion on AEM S2

HAHA ya damn right I do brotha

BTW! Did you end up going with a Holset over FP? I could have sworn that you ultimately decided on an HX40. The reason I ask is because I miiiight be taking in a local's built 8.5:1 2.0L with the 6-blade HX40. It VD baselined around 350+ on Link v3 lite in SD and needs a complete retune. I was curious to hear your experience and what kind of powerband+boost curve you are/were seeing for comparison.

The underhood madness of a large turbo 2.0L 4G63T. Break-in has been completed, and a few items will be addressed before the next step, such as FP intake pipe, sealed OCC w/ vac, wiring, etc.

Yes, I can [and just did] derail my own thread LOL!

I have a 7blade 70lb/min HX40 on the shelf. Still rockin the 14b for now until I gather the final pieces to build the spare block into a long rod 2.4. Just need a 7bolt 2.4 crank and torque plate and it can all go to the machine shop this winter.

I can so see myself maxing out my 13G's before stepping up to DR750's. Thanks for sharing.

Curious...How much boost for the 350hp on the 2.0 hx40?

Very welcome and thanks for commenting! I believe it was Saf from France that pushed 13G's to 430AWHP on Pump-E85 and AEM EMS.

[I just double-checked to confirm and yes, I remembered correctly!]
