AEM EMS Ecu vs Stock Ecu / Evo IX / 9 Dyno Pull - MagicManRed

what was the difference in HP and TQ I couldn't tell. I just bought an aem ems while deployed. Can't wait to get it installed!

@octavioveliz

Stock ECU at that time made ~380whp and ~330tq

AEM EMS made ~420whp and ~370tq

Not a lot of time was spent on the OEM ECU tuning. AEM doesn't necessarily give you more power, just more functionality. If you plan on driving your car daily, stick with stock ECU. A lot has been accomplished with the stock ecu since a year ago. They are very capable. If you plan to buy an AEM EMS, buy new, and buy the V2 box with a steel MAP sensor with appropriate boost (3.5bar/5bar)

what is your timing on 25 psi with 93 pump ?? thanks. nice car

@elpeladodelsamba

Since then, a lot has changed... sorry for the delayed reply... but I'm now running a FP Black converted to ball bearing, and a 2.4L stroker block with aluminum rods and 10.5:1 compression pistons on a lightweight manley crank. I'm putting out 28psi max (can't go much more with that compression on pump unless I go E85) and at that PSI, My timing is about 1 degree on initial load at 4kRpms, then climbs to 3.5 degrees by 5kRpm then 5.5 at 6kRpm, then sees no more than 6degrees.

Note that depending on what ECU you run, the timing values aren't realistic. I have noticed that a stock ECU will need a much higher ignition timing degree value to match that of a value in AEM. If you aren't a tuner, don't mess around too much with high rpm/high load ignition timing... you may blow stuff up lol. Happy tuning :)

So the AEM EMS gave you around 40whp increase, solely on that?

yes sir. His name is TK, short for Thanos Kavas. (Long story)
