I understood what he said. All I'm saying is that 90% more crap at 200% of the price doesn't make it 90% better. The AEM EMS isn't all that great. Now I'm not saying that from experience but perception. The fastest DSMs don't use the AEM at least last time I checked. IIRC Shepherd is using ProEFI, Rau was using Motec and Kiggley is using Haltech.

 

Price is irrelevant when you're comparing capability. Tuning, and tuning devices, are not about making more or less power. They are for making your car run properly, consistently, under the needed circumstances. When asked the question of "which one is better" there will be a different answer than "This is my budget, this is what I want to do, what should I get?"

Cherrod is correct, you're completely misunderstanding my point. I don't know why you're taking offense.

 

I'm not taking offense. I was trying to make a joke with the Dong remark.

 

Well in the end I think we can all agree I was right

 

From the point of data logging, extra input monitoring and output control the AEM EMS is the dominant product. However for a 500 HP street car retaining a Mitsu Mass Airflow sensor the V3 Link would be the better bargain and easier for the average person to use. Although high HP cars running speed density, additional injectors, etc would clearly see the benefits of the AEM. As far as Motec, Haltec, etc; they all require building an engine harness and splicing in the the desirable functions of your factory chassis harness. The AEM is plug and play with about the same modification as installing a SuperAFC if converting to speed density. The only FAIL I see in the AEM is the lack of an OBDII connection to get a valid emissions inspection on newer vehicles.

I also have to agree with HighPSITSiGuy about the cylinder heads and throttle bodies. I have spent $1000s on different TBs and sheetmetal intakes over the years only to find you may save a few pounds and only see real gains pushing 35+psi over 8K RPMs. For example I have made 530whp with a stock unported 1G TB, intake and head(only valve work and cc balancing). As great as these high flow CNC ported heads sound they are not practical for a regularly driven car and actually cause losses in the low RPM range. Lots of people miss the fact these 800+HP 4 cylinders don't start making squat for power until you get to 5500 RPM, not very efficient for a street car. 600 HP at the crank is about the best you will see and still have desirable everyday street manners.

 

See, I like that about my car. Not making boost in the lower RPMS means better gas.

 

lmao thanks for all the help guys, you managed to refuel the whole argument of DSM tuning. So by the looks of it none of you are actually run AEM EMS.

 

if you buy an EMS, you are a retard. I tuned my low 12 sec, stock motor gsx with an AFC for 30+ psi. I only switched to DSMlink to streamline the tuning and to actually be able to tune 'right' by playing with the timing, etc. There is ZERO need for an AEM, ZERO.

 

I couldn't afford to buy that shit, but the car came with it, so i have to deal with it. It got tuned at AMS but runs like shittttt.

 

Sell it and pick DSMLink. Then bring to me and I'll tune it
